Takashi's family moved into a new neighborhood, so Takashi decided to use this opportunity to reinvent himself from a goody-goody into a punk. He heads to the barber where he runs into another high school age kid with a very normal haircut. Takashi asks for a bleached perm so that he can stand out in school. As he's leaving he discovers the other highschool kid, Itou, got his hair spiked (and will also stand out).

Turns out both of them transferred into the same school and had the same idea; to reinvent themselves into delinquents. Needless to say they become friends and delinquents together.
