Gyuuki was one of Amiba's enforcers, blessed with the strength of a bull. He made his living challenging random men to arm-wrestling matches, dangling a month's worth of food as the prize—a huge incentive in the post-apocalyptic wasteland. The catch? He'd position matches on a table saw, and his victims would lose their arms to the blade when they inevitably lost. It was a brutal grift that worked until Kenshiro showed up.
When Kenshiro accepted the challenge, he didn't just beat Gyuuki—he snapped the guy's arm clean off, shocking everyone watching. Habu, apparently Gyuuki's superior or handler, took the humiliation personally and knocked Gyuuki unconscious for his failure.
