When strange buttons show up across four different realms, a variety of adventurous and eccentric people push them and find themselves thrown together to form a class at a mysterious school in a parallel universe.

The unlikely group of classmates introduce themselves on the first day of school after everyone settles in.

As the students start to wonder about what the school really is and why they are there, Tanya theorises about Ains.

When the students discover they are all from different worlds, they share their backgrounds with one another.

When the students learn they are expected to compete in a talent show, they worry that they have no talent.

The students must choose their class representative; Aqua wants to keep Ains away from the job, but Albedo doesn't want Aqua to have it either.
