Taro Yamada loves superheroes. After he literally lost his shit at the entrance exams for high school, he decided to enroll at Saint Claus Academy in Northern Europe for a year. But instead of the Super Club for ongoing heroes, he discovers the wrongly translated Spa Club - and four rich, butt naked guys sweating in a sauna. Luckily, he owns a bottle of special sauna essence which can make every dream come true.

Now it's time for sauna, not drama!
