When Supernatural Battles Became Commonplace - Season 1 Episode 10 Fool's Labyrinth

As Jurai goes on his pool date with Chifuyu, Madoka tries to concoct a plan to get Chifuyu to hate Jurai. However, Jurai overcomes her expectations each time, leaving Madoka to become impressed by him as well. The next day, Sayumi brings Jurai to the very same pool, where Shizumu equips her with a swimsuit that would allegedly become see-through if she gets wet, but it turns out to be a normal swimsuit. Later that night, Tomoyo tries inviting Jurai to the pool, only to learn he is going on a family vacation with Hatoko.
