Desert Eagle 1 — Ken Wakui

Ichigo Washio is a young man with a bright future -- a bright future, that is, within the gangs of Shinjuku. When he meets Ringo Takamizawa, a fellow student hell-bent on revenge on those who took everything from his mother, the gregarious Ichigo doesn't think twice about helping Ringo -- even when it means it'll pit Ichigo against men he's looked up to his whole life. But Ichigo knows he's in the right, and with his new friends and a healthy dose of stupidity to guide him, he's ready to return justice to Shinjuku's streets! From the author of Tokyo Revengers!
