Aoshima was mister Aoshima's middle weight fighting dog, named after his owner.
Shin Gaiden Benizakura Hen
Aoshima is on a walk with his owner when they meet Kazuhiro Ishii and his young dogs Benizakura and Jirokichi. Jirokichi starts to bark from fear of Aoshima's presence and the fighting dog suddenly turns angry and attacks him. Mister Aoshima hits his head in the process and Kazuhiro tries to call for help.
Benizakura jumps between the two dogs and pulls Aoshima off of his brother. Benizakura and Aoshima roll until Benizakura hits the bigger dog against a fence.
Aoshima either died from the hit or was later put down because of his bad wound and aggressiveness.
