Chika and Touka knock on Sensei's door at night, still drunk from the dorm war after-party. They are somewhat confused about what they're doing, but Sensei eventually establishes that they want to take part in a lingerie contest. After showing off for him, both of them pass out. Sensei gets Nodoka to help return them to their rooms, and also to pass on his decision as to which of them was the winner.
