In any age, booze is always tasty... On rainy days or sunny days... Booze never changes in how delicious it is. What does always change, is the hearts of the people who drink...

—Jiro on an Emerald Dragon.

Jiro (次郎 Jirō) was a legendary Gourmet Hunter who is well known as the Knocking Master in the Gourmet Age. Despite his elderly appearance, he was one of the strongest individuals in the world and was one of the three disciples of the legendary and revered "Gourmet God" Acacia. Despite technically being retired; before his death he would, on occasions, hunt for ingredients for his own pleasure and like many other well known individuals, he sought the holy and phantasmal ingredient known as GOD.[1]

Before he gained the title of Knocking Master (ノッキングマスター Nokkingu Masutā) and even before he trained with Acacia, Jiro held a more sinister title, the Rampaging Beast (暴獣 Bōjū). He gained the title long before Acacia took him under his tutelage as Jiro was raised as a wild and brutal individual by one of the Eight Kings, the "Wolf King" Guinness.

In the final chapter of Toriko, it is revealed that Jiro is a reincarnation of second son of a family of Gourmet Gods.


Jirou Designs & Expressions

Jiro is easily recognized by his pompadour hairstyle as well as his goatee. When he does not use Knocking on himself, he appears as a frail hunched old man. He can use Knocking on himself to increase vastly the muscle mass of his body, though when not in the Gourmet World he does not seem to take this very seriously, only needing to increase his upper body to perform Knocking on a Devil Serpent and successfully Knocking several Puffer Whales.[2][3]

Gourmet World Jiro with his eyes open.

When he appears in the Gourmet World to save Toriko, Jiro's hair and goatee turn black and his body appears to be well-built, similar to Teppei's and he appears to become younger overall.[4]

When in his usual "old man" state, he wears ragged and patched up clothing and cheap sandals that makes him resemble a bum, but when in Gourmet World he dons a tight black jumpsuit with bandages around the waist and right arm. When hunting in either form, he wears a blue leather vest in which he keeps all his knocking equipment and the vest can expand along with his size.

Young Jiro's full attire during his training days.

During his youth, Jiro's appearance heavily resembles that of Teppei; however unlike him, Jiro's body had a heavier muscle build. He is shown to have sported his signature vest albeit he did not wear anything underneath it and wore shin-length pants which is accompanied by a pair of black kung fu sandals. When he was in his casual attire, he simply wore shorts and did not wear any upper body attire.

At the end of the Human World Act while he is encouraging Toriko, he does not have a goatee.

When he takes on his Rampaging Beast appearance after releasing his Knocking, Jiro's body becomes extremely slender but still maintaining his muscular structure with his body now sporting and extremely dark skin tone. His pompadour grows larger and his hair becomes wilder in appearance. His stomach becomes thinner and his shoulder become broader, he also gains an increase in height as well as arm span.

When he releases all of the seals Acacia placed on him, he reverts back to a muscular human form, but with darkened skin, and black eyes with glowing irises and in this form his body appears to revert Jirou to his physical prime as all signs of aging have disappeared. He also has large saggy earlobes.

As the "Knocking Master"[]

Jiro is a jovial and kindly man of simple pleasures, he goes so far as to state that to him booze is life. The simple kindness of unselfishly offering him a drink is enough to gain his eternal gratitude, causing him to revive Komatsu and save Toriko from the Gourmet World when asked without asking for a reward. He even goes to Drunken Frenzy Island, the source of much of the Human World's liquor "8 times a week".

According to Teppei, Jiro is a very mellow person who is almost always smiling. Teppei's shock at seeing Jiro stop smiling at the sight of a previous hunting ground which had been stripped barren of life influenced Teppei to become a Saiseiya. Long ago, before he became Acacia's disciple, he was known for having a brutal and slightly aggressive nature. 

As the Second Son and Disciple[]

So yer sayin' that if the cells admit their defeat, the wound will stay? Then I'll never have a scar like that in my whole life!

—Jiro about his Gourmet Cells

Jirou taunted

Is it Jiro... Or Jiro.

As a young man, Jiro was overly prideful of himself and a very quirky, comedic person. Much like his current self, Jiro enjoyed teasing people, this was mostly seen when he teased Midora during their youth, as he seems to find it easy to tease the young Midora much to the latters annoyance. The teasing was not limited to just Midora himself as he would also tease Ichiryu from time to time, to which Ichiryu would reply in a more serious manner which annoys Jiro, most likely as he cannot find any fun in teasing someone who is so serious. However, much as Jiro liked to tease people, he is easily irritable when someone else teases him; this was seen when Acacia taunted him about his name. Jiro has a terrible fear for heights, as first seen when he was aboard the train heading to Gourmet Fortune where he stated that he can't even look outside the windows. He has had this fright since Acacia once punished him when he was young.

He seemed more egotistical in comparison to his older self, believing that because of his great abilities, his Gourmet Cells would never lose their will and thus he would never receive a scar due to his Gourmet Cells regenerative abilities. This ego extends to when he became fully known as one of the strongest people in the world next to his brother Ichiryu; when Midora praised him and Ichiryu for their efforts at stopping the Four Beast, Jiro replied to Midora that it "was an easy win" and calling Midora a "moron".




Jiro and Setsuno together at the beach.

During his youth, Jiro partnered with Setsuno as a combo, often hunting rare ingredients in the Gourmet World. This relationship seems to have extended to intimacy, as both of them have the same source ingredients on their Full Course Menu and Setsuno blushes when she mentions that she worked with him. Setsuno even change's Toriko's hairstyle to the pompadour due to her love for Jiro.[5] When Jiro saved Setsuno during Cooking Fest, he referred to her as "his dear Secchan" and she in return did the same to her "Jiro-chan", indicating that their relationship may still be quite intimate after all these years.[6]


Jiro is related by blood to Teppei as stated by Toriko and Barrygamon, Jiro is Teppei's grandfather. Jiro cares for Teppei and has trained him in numerous Gourmet Hunter arts, among them several of his Knocking techniques. Teppei himself mentioned that he became a Saiseiya in order to save the environments and ingredients Jiro cared about, citing Jiro's sad face as the reason for his path in life. When Teppei was younger, Jiro took him to a place where he enjoyed many food, but when they arrived there all the foods were gone and all there left was a desert. Teppei saw the sad expression his grandfather had so he decided to become a saiseiya to protect all the foods in the world.


As an infant, Guinness raised Jiro as a son and often captured Nitros to feed him. Due to this, his body was filled with a huge amount of dense, powerful, dark cells, thus, turning him into a creature with a power on par with one of the Eight Kings or a pure Appetite Demon.[7] He later fought against Guinness and attained most of the Wolf King's upper right fang in the battle.


While as of recent, Jiro and Ichiryu seem to be in equal terms, during their youth, Jiro and Ichiryu have a form of sibling rivalry. This rivalry usually stemmed from Jiro's ego, believing he is the strongest of Acacia's adopted children and tries to prove it by continuously challenging Ichiryu. Jiro admits that during their youth, Ichiryu would let him win as Jiro admits crying if he didn't win against his older brother. This sibling rivalry often put Jiro in trouble or being teased by Acacia. Despite their rivalry however, they eventually grow up to become highly recognized Gourmet Hunters, being titled as World's Strongest. Their cooperation in taking down the Four Beast during its rampage shows that they make a powerful team and can stop even the most deadliest of foes if they work together.

In present times, Jiro rarely has contact with Ichiryu due to the fact that he had retired from his Gourmet Hunter career and used most of his time taking pleasure in his retirement. Because of his booze habits, Ichiryu looks down on Jiro however Ichiryu still respects his younger sibling and would even invite him to dine together along with Midora. While Jiro hardly made contact with Ichiryu, Jiro still looked after Ichiryu in some form, mostly in the way of assisting his older brother during great conflicts or helping out his foster nephew Toriko at certain times.


In their youth, Jiro and Midora were in good terms with each other despite Jiro's constant teasing of Midora. Their relationship as brothers can be seen mostly as sibling rivalry of sorts as while Jiro accepts Midora as his younger brother, he didn't seem to fully approve of Midora as Midora seemed to be lackluster in terms of capabilities, going as far as to question why Acacia named Midora after a tiger even though he only took down a Flavor Rhino. While Jiro seemed to look down on Midora as a Gourmet Hunter, Jiro still respects and cares for Midora even if he doesn't show it. As they grew, Midora looked up to both Ichiryu and Jiro, especially when Jiro became recognized as a Gourmet Hunter and World's Strongest along with Ichiryu. However during the unfortunate event of Froese's passing, Jiro discovers the event and made attempts to revive their foster mother to no avail. Even after seeing Froese in Midora's arms during her death, never once did Jiro hold it against Midora nor did he have any ill will against his younger sibling.

When Midora eventually fell into a darker emotion, the two had almost no interaction with each other since then. At best, they are never seen anywhere near each. Recent events have put Jiro and Midora further away from each other however Jiro still jokes about Midora even though they seem to oppose one another (Jiro called Midora "small fry cat"). Midora kept his distance from Jiro even till the present day. While the two never saw each other since Froese's passing, Jiro still knew that deep down Midora still held their memories as a family within him. Jiro understood Midora's feelings despite their conflict, and even went as far as to question Acacia if their family was real when Jiro is confronted by Acacia. While Jiro never fully showed Midora that he cared for him, he fully shows to Acacia that he cared for Midora strongly as during his final moments before dying, Jiro made it clear to Acacia that he shouldn't tell Midora of the truth about what Acacia claimed to be nothing more than a fake family as Midora still believed strongly in their familial bonds.


He holds great gratitude towards Toriko and Komatsu for giving him sake, which he repays by saving Toriko's and Komatsu's life. He continues to regard them as good friends and acknowledges that they have great potential.

Powers and Abilities[]

Jiro is a former disciple of the legendary Acacia. As such, he is widely considered one of the three most powerful people in the world, and he lives up to this title. Joie said that, in the past, because the "Gourmet God" himself feared Jiro's might, he sealed off a part of his strength to teach him technique. Jiro was also one of the oldest characters to still live.

Jiro has shown an overwhelming amount of strength while in his younger looking body, during his trip to the Gourmet World to save Toriko, he was able to effortlessly move around below the Waterfall Basin of Life (whereas Toriko struggled to move around due to the massive difference in gravity) and was able to create an image of Toriko being chopped by an axe by merely swinging his hand. Jiro is so powerful that not only was he able to obliterate the head of a Nitro with a finger flick, but he also had the delicateness to simultaneously take away its freedom of movement. He also appears to have tremendous speed, using this speed he was able to utilize his Knocking Rifles against a herd of Mamew in rapid succession, being able to take down each of the creatures without them being able to even touch him, his speed has also allowed him to enter the Cooking Stadium unnoticed and find Setsuno seconds before a Nitro that Joie had revived was able to attack Setsuno. His physical strength is so great that even though Acacia sealed a part of his strength, he was still able to use his Grand Knocking to such an extent that he was nearly able to stop the rotation of the entire planet with his fist, and punch a part of Neo, the most powerful Gourmet Demon to ever exist, into space with just one blow.

Gourmet Cells[]

Because of his childhood diet of Nitro and other pure Appetite Demons, Jiro has a large amount of dark Gourmet Cells.[8]


Acacia placed seals into Jiro in order to control his immeasurable power. When he begins removing the seals during his fight against the Nitro, his appearance changes into a beast-like form. His strength and resistance to damage increase, his arms get longer, his teeth turn into little fangs protruding out of his mouth, his face's skin cracks and his eyes turn white with no visible pupils. He keeps this form while popping out the seals from his body one by one, until he reaches his final form. In this form he once again has a human face and human proportions but he looks different: he has darker skin, longer black hair, black sclera, and a black beard. He also looks younger and his muscle mass increases dramatically.

Hunting Method[]

Jiro usually prefers using Knocking on beasts either by utilizing tools or his bare hands. While this is usually enough to end the battle, he can also resort to his immense physical strength if the Knocking proves to be ineffective.


Jiro can inject himself with knocking needles causing his muscles to swell and his body to grow to colossal size. In his state the mere sight of him is enough to frighten off the strongest of beasts with ease. This type of intimidation has been dubbed as Intimidation Knocking.


As his title implies, Jiro uses a variety of Knocking Guns while hunting. His skill and knowledge are such that he can effortlessly knock any living creatures he comes across, even hundreds at a time, without a wasted shot. Jiro is able to use a form of Knocking on himself that result in an increase in size and power, the size and area that is affected by the knocking can be controlled, resulting in either a younger and taller body, or becoming a massive giant. He is known to be able to scare Surprise Apples up to level 92. He can even use his Knocking Guns to revive the recently deceased as he did for Komatsu when his heart stopped after using a Toriko Cracker.[9]

His Knocking ability is far superior to that of any others, second only to his teacher, Acacia. Jiro can stop the earth from rotating, causing a natural disaster and only he can remove the Knocking. He also gains access to new Knocking techniques when he removes Acacia's seals and begins changing into new forms.[10] In his intermediary form he can deflect damage by using Damage Knocking on himself. In his final form he can paralyze his enemies by blowing on them, turning them into statues, and even briefly stopping time.[11]

Food Honor[]

Jiro appears to be a master of Food Honor, as displayed by his appreciation for food and life, his high level of concentration and his mastery of Food Immersion. This comes as no surprise as Jiro is one the most powerful individuals in the world. Being capable of using Food Honor, Jiro's techniques increased in speed and strength several times over during battle by cutting down on useless movements and increasing his concentration. Doing this reduced his calorie consumption and caused his techniques to be far more delicate, allowing him to last longer in combat. He along with Ichiryu and Midora trained in "Food Immersion Cape" in Gourmet World to master this skill.

Food Immersion (食没 Shokubotsu): Being a master of Food Honor grants Jiro the hidden skill of Food Immersion, meaning he could express true, pure appreciation for food. Jiro is capable immersing himself with a meal and by that, able to absorb and save more nutrients from it inside his body than normally possible. This helped him store almost unlimited amounts of energy inside his body, enabling him to survive for abnormal timespans without food or water and supporting his incredibly huge stamina.


Knocking Arsenal

Jiro's Knocking equipment

Jiro carries many unnamed tools and knocking guns within his jacket, many of which are custom made and not sold anywhere.

  • Membrane Tool: One of Jiro's tools; it injects a special polysaccharide made from the Deep Sea Doctor Lobster to repair damaged membranes such as eardrums.
Knocking hard type

Knocking Rifle "Hard Type"

  • Knocking Rifle - Hard Type (ノッキングライフル: ハード タイプじや Nokkingu Raifuru: Hādo Taipuji-ya): A pair of knocking guns that fire needles to knock animals from a great distance. He keeps extra cartridges in his sleeves to allow easy reload.
  • Wolf King's Fangs (狼王の牙 Rōō no Kiba): An offensive tool that fits over Jiro's hand and has multiple fangs of different lengths attached to it, used to perform the Guinness Punch.[12]


Jirou Intimidation Knocking small

Intimidation Knocking (威嚇ノッキング Ikaku Nokkingu): Using two knocking guns, Jiro stimulates his own body to increase muscle mass and overall size. The purpose of this technique is to frighten off enemies without the need to fight.

Grand Knocking small

Grand Knocking (グランドノッキング Gurando Nokkingu): An unarmed Knocking technique, it is strong enough not only to perform Knocking on a large number of strong individuals but also to reduce the Earth's rotational speed to near stopping point. When performed, natural disasters happen due to the planet's rotation being slowed down.[13]

Rising Wolf Guinness Punch small

Rising Wolf Guinness Punch (昇狼ギネスパンチ Shōrō Ginesu Panchi): Using the Wolf King's Fang, Jiro can perform a powerful spiral-like blast of Appetite Energy that takes on the shape of a Battle Wolf head. Jiro states that it is powerful enough to reach outer space. Guinness is the name of the most powerful Battle Wolf, that resides in the Gourmet World as one of the Eight Kings.[14]

Big Bang other

Big Bang (ビッグバン Bigguban): After increasing the muscle mass and size in his arms and chest, Jiro concentrates and condenses the muscle into his right arm, turning it black.[15] He then proceeds to punch the opponent with enough force to send them all the way into space. It is first used on a piece of Neo.


Damage Knocking (ダメージノッキング Damēji Nokkingu): Jiro applies his knocking directly into an opponent's attack, instantly stopping the unleashed attacks within his body while the rest of the opponent's attack simply go past him.[16] As the damage which Jiro has taken is simply stopped, if the Damage Knocking is released, the attacks will then continue, if more than one is stopped, all attacks will be released simultaneously, causing heavy damage to Jiro (or as seen in the manga, cause his death) meaning it is a double edged sword. [17]


Head Shaker (ヘッドシェイカー Heddo Sheikā): Jiro grabs his opponent's head with both hands and violently shakes it, causing a definite annihilation on an opponent. It is first used on GOD.[18]


Knocking Breath (ノッキングブレス Nokkingu Buresu): Jiro applies Knocking with a forceful breath. It is first used on ANOTHER.[19]


Secret Art: Knocking Time (奥義 ノッキングタイム Ōgi: Nokkingu Taimu): Jiro stops time with Knocking. The application of the knocking is similar to Grand Knocking in that Jiro bashes the floor with his fist; however, it will only stop time on a smaller area and can be used more quickly. It is first used against NEWS to stop his attack.[20]


Eternal Knocking (エターナルノッキン Etānaru Nokkin): Jiro applies unending Knocking to an opponent, causing them to permanently freeze as if they were frozen in time. This technique is hard on his own body. It is first used on NEWS after applying his Knocking Time.[21]


Million Knocking (ミリオンノッキング Mirion Nokkingu): With incredible speed and precision, Jiro strikes an opponent a million times from every angle, allowing him to fully stop an opponent's movement. With extreme precision, he can choose any part of the body to allow movement for. This technique is first used on Acacia.[22]



In Jiro's past, he was not raised as a normal human child as he lived in the wilds. Despite living within the dangerous habitats of the world, Jiro was protected and cared for as a child. However, he wasn't raised by other human beings but rather a pack of wolves, more specifically the strongest pack in the world, the pack under the command of Guinness, the Wolf King. Guinness fed Jiro different kinds of creatures during his childhood, most of them consisting of the Red Nitro as well as several types of demons consisting of dark colored Gourmet Cells. As he was raised by wolves, Jiro had a brutal personality and an extreme power to match, giving him the title of the Rampaging Beast.

The Second Disciple[]

Acacia would cross the path of the Rampaging Beast during his ventures. It is unknown what circumstances the two met however Jiro would eventually be made the second disciple of Acacia, who, apprehensive of the enormity of Jiro's power and even more so of his brutal personality. Acacia sealed a part of Jiro's strength and planted technique into him, teaching all of his knocking techniques.[6] IGO President Ichiryu and Gourmet Corp. Boss Midora were also his fellow disciples, but unlike them Jiro never became the head of a major organization and would eventually retire after years as a Gourmet Hunter.

During his time as Acacia's disciple, Jiro spent much of his time training and hunting along with Ichiryu and Acacia himself. He, along with Ichiryu and Midora, were known to be orphans whom were found by the Gourmet God and Chef Goddess and taken in as part of their "Family". 

At an unknown and undetermined point, he became the traveling partner of a young chef named Setsuno, thus forming a combo together much to her and Jiro's delight but much to the shock of Jiro's other two siblings Ichiryu and Midora. However the exact details of how they met are unknown. The young combo traveled the world together for many years, having many adventures.

Jiro knocked the body of the Four Beast while Ichiryu repelled the limbs.

Puffer Whale Arc[]

Jiro first appeared while on a train to Gourmet Fortune, in order to catch the phantasmal Puffer Whales at the Cave of the Sandy Beach. While on it, the train had run out of liquor as Toriko had bought it all, so Jiro humbly asked Toriko for a drink and he happily gave one too the tipsy old man and Jiro swore he would repay this act of kindness.

Some time later after Toriko and Komatsu had rendezvoused with Coco and went into the Labyrinthine Cave to seek the Puffer Whales, Komatsu had been kidnapped by Buchichupon and he planned to use Komatsu as bait to lure away the other beasts but his plan backfired and he was eaten alive, Komatsu was then left alone to deal with a hoard of Scorpion Cockroaches and a Devil Serpent. As a last resort he used a Toriko Cracker to try and scare off the beasts but it mostly failed and it caused Komatsu's heart to stop and his eardrums to break due to the severity of the explosion's sound, the Devil Serpent then lunged at Komatsu but was then easily Knocked by Jiro himself in his giant form, who had just finished catching his Puffer Whales.

Seeing Komatsu's terrible condition and knowing he owed Komatsu and Toriko his gratitude, he proceeded to revive Komatsu using his Knocking Gun and then repaired his ears using the Doctor Lobster's polysaccharide as a membrane. Upon Komatsu's waking, Jiro told him to cherish this second chance at life, however Komatsu screamed in fear thinking he was a "giant old man monster", but then Jiro corrected him and proceeded to tell him that it was he who saved his life. As he left, he warned Komatsu to be careful as "something mysterious" was on its way into the cave. After he left the cave, he performed knocking on several hunters and bandits, while praising Toriko and Komatsu, and mentioning that when they reach the point of being the best hunter and chef, his full course will be close to being complete, although the meaning of this remains unknown, as his full course is already complete.

Reality of Gourmet World Arc[]

Jirou in Gourmet World Eps 50

Jiro arrives in Gourmet World to save Toriko.

After Toriko entered the Gourmet World, despite his lack of experience with it, Komatsu feared the worst so he called up Jiro to help Toriko should things go wrong, Jiro later arrived to save Toriko from hundreds of Mamews with the help of his knocking. Shortly after that he uses Ikaku Knocking on an Asura Tiger and a King Lander, scaring Toriko as well. Jiro and Toriko later sit down and talk about the difficulty of Gourmet World. Jiro then advises Toriko about his need for trusting his partner Komatsu, and Toriko resolves to train himself even further in hopes of being able to enter the Gourmet World with Komatsu.

Gatsukatsu Curry Arc[]

Jiro, along with Setsuno decided to go on a little vacation to the Gourmet Beach where the two spent some time together. While there, they ran into Toriko and Komatsu who also come to the beach seeking the rare Gatsukatsu Curry.

Autumn Break Arc[]

Jiro appears as one of the contestants in the 50th annual Gourmet Service Competition, competing for the rare Diamond Figcrystal. The second he got on stage, he was given dozens of points due to one of the judges being Setsuno.

Bubble Fruit Arc[]


Toriko, Komatsu and Jiro having a drinking party.

Toriko and Komatsu find Jiro on Drunken Frenzy Island resting in a champagne spring on the back of an Emerald Dragon. He reveals to them that the Heavy Drinker Archipelago is his most favorite location in the Human World and that he frequents it "8 days a week". The two soon join him and he offers them some of his rare Doham Spring Sake from his Full Course Menu, but much to their dismay he realized that he already drank it all before they can have any. Nonetheless the duo proceeds to party with him and enjoy all the wondrous drinks the island has to offer for the next three days before returning back to the main land.

Cooking Festival Arc[]

As the battle on Cooking Island continues to heat up, Jiro is located by Terry Cloth, Kiss, and Quinn who then report to him the events of the current situation. Jiro easily understands and goes with them to help. Along the way, they discover a rogue Hammer Tusk, a powerful beast Jiro subdued long ago, and he suspects that it could have only been revived by the saiseiya Mohyan Shaishai. He then tames the beast and uses it to take him to Cooking Island with Terry, Quinn, and Kiss following alongside him.

With things heating up at Cooking Stadium with the arrival of Joie, even Setsuno is having a hard time especially with Teppei and the Nitro under Joie's control. As things begin to look grim for Setsuno having been tied down by Teppei's roots and about to be crushed by an incoming Nitro, Jiro finally arrives and easily crushes the head of the Nitro with a simple finger flick and then prepares to fight the "Dark Chef" Joie himself. Joie is surprised by his sudden arrival, and Jiro apologizes for his lateness to Setsuno who is quite relieved to see him. He is then grabbed by Teppei's roots which forces Jiro to release a powerful and angry shout of intimidation that knocks Teppei back and leaves a nearby Brunch stunned. Joie comments on Jiro's past, commenting on how Acacia sealed his strength and added technique onto Jiro, he also refers to Jiro's previous alias as the Rampaging Beast but also remarks on how he is simply a drunkard now. Jiro then proceeds to use Grand Knocking to knock the entire planet and everybody on the island, which includes both friends and foes and also creating a natural disaster. Jiro then rips off Joie's disguise and is shocked to see the face of "Chef Goddess" Froese

Jiro, surprised by Joie's true face, watches as Joie erases the natural disaster caused by his Grand Knocking. Setsuno asks Jiro to make sure that it is Froese by attacking in combination. Jiro prepares a tool known as the Wolf King's Fangs and proceeds to follow Sestuno's attack with Rising Wolf Guinness Punch. Joie then reveals a demonic appearance and proceeds to stop their attack head on. Jiro comments on Joie's Gourmet Cells having "shown themselves" and comments on Joie's mastery of the Gourmet Cells. He also comments that for one to fully master the Gourmet Cells, they must have eaten Acacia's Full Course Menu to which he states that only Acacia and Froese have eaten. As he is about to believe Joie is truly the "Chef Goddess" Froese, Setsuno interrupts him and says that it is not Froese because Froese had a different appearance when she used her Gourmet Cells and the Chef Goddess is dead. Jiro then asks as to what exactly is the creature they are facing but they were interrupted by the arrival of Starjun

After the arrival of Starjun, Jiro notices the button pop off his jacket, hinting that something bad was about to happen. As Joie and Starjun converse, dark clouds begin to cover the skies of the Cooking Stadium, Joie states that due to the presence of Jiro and Setsuno, and the fact that Starjun's cells have awakened, he is at a disadvantage should he proceed to fight Starjun. As everyone looks to the skies above, thunder and lightning ensue. Joie states that another battle has been concluded (a battle between Ichiryu and Midora). Starjun then tells Jiro to release his Grand Knocking because "the spices will fall" stating that the Meteor Spice will fall. Jiro states he's "got no choice" and proceeds to remove his knocking. As the Gourmet Corp. and NEO members evacuate the Human World, Meteor Spice begins to fall. Both Setsuno and Jiro look to the sky, having realized what had just occurred. Jiro states the "The smallfry cat beat him eh...?" highly stating that the IGO President Ichiryu has been defeated by the Gourmet Corp. Boss, Midora. Jiro stood along with Setsuno as they observed the devastation that is the Meteor Spice, spawned by Midora to strike the Human World. 

We are Bishokuya. Awake or asleep, we are Bishokuya.

—Jiro to Toriko

After the devastation that struck the Human World, Jiro was next seen later on asking Rin what had become of Toriko. Rin told Jiro that Toriko has sunk into deep depression, unable to feel hunger and has not eaten for days. Jiro openly offered Toriko a drink as they sat under the starry skies. Jiro offered Toriko some Centipemia Nuts however Toriko flatly refuses, stating that he cannot swallow anything as of that current moment. Jiro observed Toriko's current state and notices a massive change within the Gourmet Hunter's abilities, he notices that while Toriko has not eaten, his energy is overflowing however Toriko's feelings are completely in the opposite to the positive energy Jiro has noticed. Jiro then pours some Maboro Sake into the cups, saying it was one of the drinks Ichiryu liked even though it was a common drink. Jiro was then asked why he would bring out the sake during such an occasion, Jiro then informs Toriko of their adoptive father's death at the hands of the Gourmet Corp. Boss, stating that it was not completely unbelievable. Jiro then tells Toriko that while Ichiryu's power's were undoubtedly the best, it was rivaled by his own kindness, Jiro using his past experience of being allowed to win in a fight against Ichiryu as an example of just how much kindness Ichiryu's possessed. He states that he most likely showed the exact same amount of kindness to Midora, Ichiryu allowing his younger brother to win even if it was a fight to the death. Toriko also reminisces the times in which he had fought Ichiryu however unlike Jiro's experience, Toriko tells Jiro that Ichiryu never once let him win. Jiro then states that the reason behind it may be due to the fact that Ichiryu had sensed Toriko's potential and knew that one day Toriko will be able to defeat him in combat. Toriko merely goes against the Knocking Master's words, saying he was weak however Jiro inspires Toriko to once again stand strong, saying that since Komatsu still lives, all he can do is "make a big lunge forward now". Toriko, moved by the words of Jiro, stands and walks away from the scene. Just before he departs, Jiro asks the former what his dream is, telling him to look back into it. Jiro then gives his final words to Toriko by saying that they are "hunters, awake or asleep". 

Billion Bird Arc[]

As the devastated Human World slowly begins to rebuild itself from the Meteor Spice that had rained upon them, Jiro along with his partner Setsuno visit the Gourmet World, believing that the Human World will soon recover. Jiro and Setsuno are seen in the former training grounds of the Three Disciples, Food Immersion Cape. Here, Jiro and Setsuno find Ichiryu's Hors d'Oeuvre, the Million Tree, growing healthily along with Food Immersion Flowers in what Setsuno claims to be a land that has long since dried out. Setsuno asks whether it was revived by Saiseiyas however Jiro says that it was Midora himself who grew the tree, using Ichiryu's technique, to use the tree as a replacement for a gravestone. Jiro comments on how Midora was the least adept disciple during their youth but now he has become even so powerful that he himself cannot even handle him but Setsuno tells Jiro that he need not worry about Midora as he will eventually pay for his actions but to worry about Joie. As they wait for Toriko and his friends, Jiro and Setsuno state that they will not return to the Human World but will do the best they can to help. Jiro questions whether the Human World would be alright but Setsuno reassures him that all will be well.[23]


Jiro makes an appearance again later on, travelling through Area 1 with Setsuno and Chichi, when the trio comes upon a part of the resurrected Neo which had escaped from the Farthest Kitchen. Jiro establishes early on that the creature simply has too much energy to be knocked and compares its power to one of the Eight Kings. He then powers up to defeat it with brute force, while the creature senses the drastic power-up and changes shape itself. Jiro displays an amazing control over his Gourmet Cells by transforming his right hand and preparing to attack, leading a shocked Setsuno to remind him to be careful and not hit the world with his attack.[24]

After having performed his attack on the creature and launching it to space, Jiro's hand is eaten during the moment off impact, Setsuno instantly heals it with Cure Water. Jiro and Setsuno question what the beast is and Chichi instantly knew it as Neo. Chichi explains to Jiro and Setsuno about the Flavor Sage's history with Neo. Jiro, knowing the dangers of the creature, unseals most of his Knocking applied on him in order to combat the beast itself.[25]

As the trio of legends travel, Jiro reaches the Farthest Kitchen. There, he bears witness to the Blue Nitro's failed attempt at keeping Acacia and Neo docile. Jiro catches the Blue Nitro's attention but keeps the peace between them instead of fighting them as he knows the world would be destroyed should they fight. ANOTHER, tells the Knocking Master that he is too late and Jiro agrees as Acacia is now active, proving Chichi right. Jiro decides to question the Blue Nitro and ask them their true goal. The Blue Nitro then reveal that their goal was to revive the demon Neo in its complete state and seal him for good as he is far more dangerous than any demon in existence. Jiro asks if Acacia knew all this but the Blue Nitros simply say he is already insane to even know. The Blue Nitros tell Jiro that they will kill him if they get in the way but instead Jiro offers his assistance to kill Acacia. ATOM tells Jiro that Acacia's demon must be fully revived and they will not let Jiro lay his hands on the creature; however, Jiro's thoughts oppose theirs. Hostility grows between Jiro and the Blue Nitro and in order to meet them on equal terms, Jiro releases his final knocking needle from his heart, revealing his true appearance as the "Rampaging Beast".[26]

Having unsealed the knocking seal in his heart, Jiro takes on a beast like form. As he readies to fight the Blue Nitro, ATOM attempts to tell Jiro what Neo is and what they are dealing with.[27] However due to Jiro going through the process of unsealing himself, Jiro simply smiles and tells ATOM that he would teach Neo how to truly instill fear to its prey. With no hope of talking things through, the Blue Nitro and Rampaging Beast engage in combat.[28]

As PAIR keeps an eye on Acacia, PAIR would eventually ask Acacia and Neo for assistance.[29] Jiro is next seen fighting the rest of the Blue Nitro and having an advantage over them. When the Blue Nitro manage to finally gain some footing in their battle against Jiro, NEWS attacks Jiro with a devastating blow; however, Jiro simply stops the damage from occurring with his knocking. Jiro then reveals he still has many knocking seals around his body which Acacia applied. With the Blue Nitros questioning what he is, ANOTHER states that Jiro is human. Jiro then reveals that while he is human, he ate lizards, more specifically the Red Nitro, as a child as he was raised by the "Wolf King" Guinness. He then proceeds to attack with Guinness Punch, which the Blue Nitros thought would destroy the Human World; however, Setsuno has applied her barrier to prevent any damage to the Human World. With Jiro releasing the final seals in his body, he states that he is finally ready to fight with his full power.[30]


Jiro breaks ANOTHER's Golden rope

Jiro having released himself of all his Knocking seals prepares once more to fight the Blue Nitro. ATOM fearing that they cannot defeat Jiro in combat instead decided that they should cook him. All of the Blue Nitro prepare their Golden Cookware and ANOTHER ties Jiro with her Golden Thread. The Blue Nitros explain to Jiro that they thrive through their cooking; however, Jiro simply makes small comments about what each of the Blue Nitro have said. He questions why they have prepared the Golden Can and GOD replies that they will cook Jiro. Having heard all of their comments, Jiro then mocks the Nitros by stating even appetite has a sense of humor. He escapes the Golden Thread and proceeds to attack the Blue Nitros, commenting that he is not laughing at their jokes. He uses Head Shaker to destroy all but one of the Life Orbs attached to GOD. Each Nitro attempts to attack Jiro using their cooking abilities, but he simply counters each one. Having defeated all but ATOM, Jiro comments that he has seen ATOM somewhere before, but it focused on something else. Jiro looks at what ATOM sees and Neo decapitates Jiro in an instant. Acacia reveals his face to his former student while Jiro smiles as he meets his old master once again after many years.[31]


Jiro demands answers from Acacia.

With Jiro's head removed, it eventually transforms into a soul from the Life Orb Jiro took. Jiro uses his Million Knocking to prevent Acacia from using anything but his mouth. He comments on the usefulness of the Life Orb he took and begins to converse with his old master. Jiro begins by asking whether Acacia felt true emotions when Froese died and when they were together as a family. Acacia simply attempts to lure Jiro towards him but Jiro continues to ask his question. With no luck on luring Jiro, Acacia instead insults his former student by commenting he had no brain as he was raised by animals. Acacia attacks Jiro without notice and Jiro attempts to cancel his attack. However unbeknownst to Jiro, Neo has already revealed its face and instantly consumes Jiro's Grand Knocking. Defenseless, Jiro is taken by surprise as Acacia manages to move and instantly put his arm into Jiro's mouth. Acacia comments on how he was the one who taught Jiro all his technique and proceeds to release the Damage Knocking. With his Damage Knocking released, Jiro takes the attacks from the Blue Nitros all at once, he attempts to stop the attacks but to no avail. Acacia then says his farewell to his second son and answers Jiro's question that all his emotions and his tears were simply fake. Enraged, Jiro screams at his former master and warns him not to tell Midora the truth as Midora still believes in their past. Acacia simply questions whether memories have taste. Jiro's death throes are heard around the world with the exception of the small area where Midora and Joie are located due to Joie's Warp Kitchen.[32]

In Area 0 Teppei is uncertain how to Knock the planet, so Jiro, sent by Ichiryu, guides his grandson through the process and bequeaths his title.[33]

Anime and Manga Differences[]

In the anime, when Jiro is first seen in the Labyrinthine Cave to save Komatsu from the Devil Serpent, he is still in his normal form while in the manga his body was already Knocked when he found him. The anime also shows him with his eyes open at least twice while in the manga he was not seen with his eyes fully open until much later in the cooking festival arc.

Appearances in Other Media[]

Toriko: Gourmet Survival 2[]

Jirou GS2

Jiro in Toriko: Gourmet Survival 2.

Jiro makes his video game debut in Toriko: Gourmet Survival 2 as an assist character. He along with the Four Heavenly Kings, Komatsu, Koryou and Setsuno was asked by Fond De Bohno to aid in his ingredient procurement trek through the Gattsuki Continent. He is a powerful ally capable of instantly Knocking beasts in dire situations.


  • Jiro's name contains the second pronunciation of the Japanese character for "two" (ji), referencing his status as the second disciple of Acacia. Jiro's name is also the homonym for the Japanese name meaning "second son".
    • This fits with Ichiryu "Ichi" (One) the first disciple.
    • As well as with Midora: "Mi" is one of the pronunciations for three in Japanese.
    • It should be noted that just as Ichiryu is "First Dragon", and Midora is "Third Tiger", Jiro could be the "Second Wolf", as Ro is the compound pronunciation for wolf.

    • When in the Gourmet World, Jiro is wearing a blue jacket similar to Kenshiro.
    • Kenshiro is a master of Hokuto Shinken, which uses the pressure points to manipulate the body to various effects, which often results in a gorey explosion. This is similar to the idea of knocking, which Jiro utilizes.

  • Though it’s only a theory and no confirmed evidence, some people theorized that Guemon is Teppei’s father therefore if confirmed he would be Jiro’s son.
