It's the start of a new school year. Nagatoro is planning to join the judo club and the art club gets a new member.

Sunomiya encourages Senpai to ask Nagatoro out on a date. On a late walk home Senpai tries to ascertain if Nagatoro has anywhere she'd like to go on her next school break.

Pursued by Gamo and Yoshi who aim to preserve Senpai's virginity and Sunomiya and the President who aim to protect and fight for Senpai's love, Nagatoro and Senpai set off on their date to the aquarium.
