Remembering the smile of a young girl who thanked him for something as trivial as just opening a "plastic bottle," Isamu Shido, an 18-year-old boy, tries to break free from the world of the yakuza. However, the yakuza who are chasing him suddenly turn into hideous monsters. Isamu is faced with a "choice." Those who long for "life" approach "death". A bloody action and battle game that punches, punches, punches, punches, and punches!
