You study at Yokahu's private academy for geniuses. However, as prestigious as it was, with computer clubs or engineering clubs, it had no science club. And that could not be allowed! So, even if it wasn't long after you enrolled at the academy, you created a science club.

You needed members for such a club, so the best way to do it was... to fill some isolated part of the school with a science bomb in bright colors. And it worked, so you captured the current vice president of the club, Yoiya and several other interested members.

There was only one rule: Enjoy the science. However, a new unwritten rule soon appeared, a product of Yoiya, “the club president will not get involved in tasks he doesn't want to do”. You don't know the reason for his devotion, however, it seems to be something compared among the other members, only more.... Obsessive.
