Ep. 6: Houtarou investigates a classroom disturbance and Eru's unexpected anger with the club.

During a school day, a loud disturbance interrupts Houtarou’s class, prompting him to investigate later. After school, he joins the Classic Literature Club, where Mayaka confronts Satoshi for missing a date. The members engage in a philosophical debate regarding anger and the Seven Deadly Sins. Houtarou recalls hearing Eru’s voice during the earlier commotion and questions her about the incident. While he deduces that the disruption stemmed from a teacher’s misunderstanding, he remains unable to determine why Eru reacted with anger during the event, leaving the cause of her emotional response unexplained.
