One day, Mari, a teacher, visited Yugo's house, a student who refused to go to school in the homeroom teacher, with her husband and a philosophical teacher. The school abandoned Yugo because of his problematic behavior, but despite his opposition, he visited his home. However, as soon as Yugo welcomed Mari, he arrested Mari and Tetsugaku to drink tea with sleeping pills, and knocked Mari in front of Tetsugaku. Satoshi, a Yakuza's father appeared in the middle of his performance, along with his subordinate thugs, and all three of them walked around the ball.
