Battle Island (バトルアイランド Batoru Airando) is a place where numerous beasts with a lust for battle reside and battles between them take place here regularly. The island is home to the highly potent Battle Flower, a plant which increases the ferocity and will to battle of living creatures and acts as the main cause of the island's constant battles. The island is also home to a breed of strange sentient apples known as Surprise Apples which are naturally horrified by the constant battling and become more delicious the more they are scared by the island's inhabitants.
