The class has sided with the scheming Maho and they all decide to give Yukino the "silent treatment." As time goes on and it appears that things won't change, Yukino knows that she'll have to confront her saboteur and put an end to the harassment... but how?

Summer has arrived and it's a time of separation. Arima is going away for a Kendo tournament while Yukino has made new friends. Even Tsubasa has taken a liking to Yukino, but something's not right... she's grown a little too attached.

Yukino isn't all that interested in the culture fest until she finds out that the class that puts on the best show gets the test notes of a student who went on to Tokyo University!
