One day, Mari, a teacher, visited Yugo's house, a student who refused to go to school in her homeroom class, with her husband and fellow teacher Philosophy. The school had abandoned Yugo for his problematic behavior, but despite her opposition, she came to visit him. However, as soon as Yugo welcomes Mari in, he makes Mari and Philosophy drink tea with sleeping pills, and breaks Mari down in front of Mari and Philosophy. Her father Satoshi, a yakuza who appeared in the middle of her act, and his subordinate thugs, and three people, circled the ball.
