Crazy Boys (1988)

Tamotsu Iwaki (Masaya Kato), also known as "The Dandruff Cancer," was admitted to a juvenile training school in the summer when he was 18 years old after being hit with dirt on his car. At first he is at odds with Ginji (Shinobu Sakagami) and others, but eventually a friendship develops between them. One day, Gan escapes, falls in love with a beautiful girl, Kanako, whom he met at his friends' apartment, and attacks her in an elevator, but is captured again. After being discharged from the hospital, Gan meets Kanako again, and although they are repulsed by each other, they become attracted to each other.
