Concerned about failing his test on account of being bad at mask clearing, Iori tries to devise a way to practice without Kouhei or Aina knowing. The gang rents a car, but it ends up being two cars since one won’t fit all eight. Turns out Aina can drive a manual truck from helping out at a rice farm.
Many a misunderstanding due to lack of proper context ensues, both at the market when Shinju and Ryuu order strangely-named fish like “Hamazaki’s Wife” or “Chubby High Schooler”, and back at the rental house.
Iori decides honesty is the best policy, so tells a weary Chisa when the two pair up to cook together. He asks her to help him practice, but when both Aina and Kouhei come into the kitchen, from what they overhear they believe Iori is asking Chisa out…and wants to be tied up and stepped on.
Aina wakes up to find Chisa’s bed empty and goes out to find Chisa holding him underwater with her foot. She fears something very strange is going on, and doesn’t believe Iori, but believes Chisa. Turns out she wouldn’t have laughed about Iori’s mask clearing, but would have helped if asked.
In fact, she joins Chisa in pressing him underwater with their feet, prompting a passerby to call the cops. Unfortunately, Chisa and Aina are already back in bed and Iori is alone and naked in the pool when an officer arrives.
Iori isn’t arrested, but he does catch cold, so he can’t participate in training exercises that day. Azusa stays behind to take care of him, using green onions as a home remedy (one ’round the neck, one where the sun don’t shine, which Iori rejects).
When Azusa learns Iori hasn’t been sleeping because he’s nervous lying beside her and Nanaka, Azusa only half-jokingly suggests they have sex so he won’t feel nervous. Iori has a legit shot at sleeping with her here, but sheepishly declines.
However, when Iori learns that Tokita of all people has a girlfriend, he ends up drinking—a lot—so by the time the others return (Kouhei and Aina with certification cards in hand), he’s passed out, naked, with Azusa’s home remedy successfully, er, deployed.
