The time draws near for the deadline to gain at least 70% approval from the students of Seioh for student festival, but unexpectedly the clock in the clock tower blows up, destroying the student council room along with it. Just when things look bleak, Shimojima shows Manami and her friends the old, abandoned Seioh boarding house and they start to clean it up to create a new student council room. Eventually, more students start coming and a huge group effort is underway to cleanup the entire boarding house.
