He is very caring towards children especially the ones in Nerg. However, having been the leader of the Gourmet Yakuza, he must be capable of extremely cruel deeds. He is very silent and collected, being unfazed by Rap's accusation of betrayal.

Powers and Abilities

Ryu is assumed to be strong because he was the former boss of the Gourmet Yakuza and had never been arrested before. Moreover, in order to manage such a powerful, widespread organization, he is bound to be a skilled, charismatic leader, capable of taking even ruthless decisions cold-bloodedly. He is able to survive in the Gourmet World. Since he has a sword, he is likely to be highly proficient at wielding it. Judging from the number of scars on his whole body, he probably possesses high resistance to pain.



He quit the Gourmet Yakuza so he can go to the Gourmet World with confidence, following an invitation by Yosaku for unknown reasons. He puts Match in charge of the Gourmet Yakuza.

Bubble Fruit Arc

He and two of his subordinates were called to a meeting by Ichiryu in the Gourmet World. During the meeting, Rap says that he is suspicious of Ryu because he recently joined the 0th Biotope. Yosaku tells him to shut up and that Ryu is the type of man that would never betray them.

Cooking Festival Arc

Ryu, his two men and Rap are seen standing in Sector E, the Continent of Beginnings, waiting for everyone else to return. Rap states that no matter who makes it and who doesn't, their job is to survive until the others are back. Ryu spots Nijsseni and several Nitro and says, deadpanned, that the top of the Bishokukai is not there. Making a pun on their names, Nijsseni spats back he was sure to meet Ichiryu, and is disapponted to find only Ryu.
