Mahiro's mother, Yoriko, wins some tickets in a lottery for them to all go to the pool. Nyarko wears an amazing sexy and commando bathing suit to try to tempt Mahiro, as well as asking him to rub sun tan oil on her in an indoor pool. As Tamao works at the takoyaki stand that Luhi runs at the pool, she notices that Luhi seems to be troubled by something and tries to help her out...
I thought it'd be more fun 
if we were all together...

cuando estamos todos juntos.
Es que creo que cuantos más
seamos, más nos divertiremos.
Seria mais divertido se
 estivéssemos todos juntos...
