Sports day is officially upon Katagiri High. Miyamura has never had a reason to look forward to the school-wide event, but something (or someone) may just make his last sports day in high school one to remember...

Nakamine-sensei may be oblivious, Terajima-sensei may be strict, and Yasuda-sensei may be a hopeless pervert, but they all have one thing in common... They're all teachers at Katagiri High!
