Omake Gif Anime - Bokutachi wa Benkyou ga Dekinai - Episode 9 - Rizu Squashes Bug

Rizu knows exactly how to handle a cockroach since she's the daughter of a restaurant owner.

The first half of the episode dealt with Mafuyu-sensei's dirty apartment again, but more importantly, her huge fear of cockroaches. Considering how much garbage she accumulates, she should have more experience with them. Nariyuki agreed to stay until the bug was dealt with by getting a tutoring session... in history, you scoundrels!

Nariyuki stayed so long, Mafuyu-sensei ordered food delivery. Of course, it was from Rizu's udon shop. She was miffed in some combination of tutoring loyalty and love rivalry, but she showed who was superior in cockroach killing.

The episode's second half had Nariyuki taking over his mom's shift at a retail store. She didn't tell him it was the lingerie store his female friends go to, though. Things happened™, and he ended up in disguise helping Rizu and Uruka buy new bras.

Uruka wondered which lingerie set a boy she liked would prefer. How specific... Nariyuki preferred the light blue "elegant" one, but really, he should have said both sexy and elegant ones. The correct answer was BOTH!

Of course, a lingerie shopping scene would not be complete unless the other members of the harem showed up. Mafuyu-sensei was already there, but needed help unhooking a bra. How those mascot paws could handle that appears to be anime logic. And Fumino showed up later, because she didn't want to feel inadequate next to her friends Rizu and Uruka the Size Queens. She ended up in a worse situation when she discovered Nariyuki knew her exact measurements and saw her inferiority complex.
