Ikebukuro West Gate Park plot
Makoto lives in Ikebukuro West Gate Park, an area known for juvenile delinquency and gang activity. One of Makoto's best friends from high school, Takeshi, is the leader of one such gang, the G-Boys. Makoto is known as a tough and clever man, and while trying to solve the mystery of a friend's death, he becomes a somewhat unwilling helper in many of the IWGP citizens' mysteries and problems. Meanwhile, tension rises between his best friend's gang (which Makoto does not want to join) and a new gang, the "Black Angels".
