Advisor! Episode 5

When Tsumugi's application to reserve the hall for the light music club is rejected due to it not officially being a club, it becomes apparent Ritsu had forgotten to fill out the required form. Yui's friend Nodoka Manabe, who is a member of the student council, offers to register them, but says they will need an advisor. The girls ask one of the teachers, Sawako Yamanaka, who rejects the offer until Yui figures out she was one of the previous light music club members, and Ritsu plans to blackmail her with the information.
