Shinjiro Hayashida

Kamiyama's first friend at Cromartie, noted for his fake purple mohawk. Hayashida is the one delinquent that helps Kamiyama blend in to the bewildering environment of Cromartie High. Although streetwise, he is dumber than the gorilla and doesn't even understand basic math. His signature purple mohawk was revealed to be fake in episode 17, but in episode 8 you can see him take it off for a brief second
