Autumn season. School classes are already in full swing, but you, not being a diligent student, safely skip classes outside the city, on an abandoned pier. Walking along the pier, you suddenly hear the sounds of a gunshot and decide to check what's going on. Hiding behind a wall, you look in the direction of the sounds and see this: a well-known member of the port mafia, Dazai Osamu, aims at his opponent and shoots him in the head without hesitation.
