Plot
Near the end of summer. Hibiki,Akemi and Ayaka go to the beach. Using the bus. On the bus there is Satomi by coincidence she wanted to be alone (not with any student) whilst hoping that they will part ways at the beach.

They notice that there isn't anyone on the bus yet it's near the end of summer.

At the beach there is a sign saying no swimming allowed, a stranger walking by tells them that there was a school of hammerhead sharks off-shore. Hibiki wanted to get hit on at the beach (Satomi had the same plan). Sitting there doing nothing. Akemi wanted to exercise through swimming, and decided to perform Burpes so the trip isn't a complete waste and convinces the others to join in.

People passing by look at them weirdly as they are doing exercises on the beach.

Afterwards, Satomi is complaining about being sore, while the others are fine.
