Let this place be an Alternate Universe!

If there isn't an alternate universe, then we'll just make one! Yatsusaki Yuudai, an enlightened high-schooler who lives by the motto "Live life in moderation". Jougasaki Kotonoha, the eccentric girl who wants to be in an alternate universe. It seems like the meeting of these two polar opposites will cause a huge disturbance in Yuudai's mundane school life! It's a weird story of an Isekai club that establishes an alternate universe... ish!
