Bokutachi wa Benkyou ga Dekinai S2 - Episode 8 - Uruka Teaches Swimming

Uruka had to tutor Nariyuki in swimming, but she's much better at doing something than teaching something.

Takizawa-sensei, the gym instructor and swimming coach, had to help Nariyuki get his grade up her class by giving him extra lessons to pass the swimming requirement. This happened at the same time as the swimming club's practice, which gave us good looks at Uruka again. Mafuyu then had to take over from Takizawa-sensei because the latter forgot to turn in an application. That meant we got yet another episode with Mafuyu in a swimsuit.

When Mafuyu saw how badly Uruka was at explaining how to swim, which her teammates also saw and pronounced her an idiot-savant, she sighed heavily and stepped into her usual teaching role and the usual circumstance of Nariyuki seeing her in a skimpy outfit. She let Uruka take over when both she and Nariyuki got the gist of her lesson.

In the showers later (thank you for the glorious tan lines of Uruka and the long legs of Mafuyu), Uruka noticed that Mafuyu had an athlete's body. She asked Mafuyu how she dealt with the pressure of competition, and Mafuyu gave her some good advice about not even trying to calm down, but to accept and maybe even enjoy the excitement. That helped Uruka win her big swim meet.

Because of her big victory, Uruka was advised that she might have an opportunity to go to an Australian university on a swimming scholarship. This would mean going to a different college than Nariyuki, but it also meant having to get way better at English. After some comedy based around Uruka avoiding Nariyuki because of her preoccupation of being apart from him, with some help from Fumino, Uruka decided the swimming exchange program would be best to aim for. This also meant she would have to spend more time with Nariyuki until graduation!
