Mysterious buttons appear in the worlds of Tanya the Evil, KonoSuba, Overlord, and Re:Zero. When the characters push them, they're taken to a place they'd never imagined...

Now that everybody's settled in, it's time for the first day of school, which means everybody has to introduce themselves.

The students realize that they're all from other worlds, and begin to share their backgrounds. But some are luckier than others...

It's time for the talent show, but none of the students are talented at all. The KonoSuba crowd in particular...

It's time to pick the class rep! But Aqua doesn't want Ains to do it, and Albedo doesn't want Aqua anywhere near the job.

Emilia's the class rep now, but it's really hard. But she wants to do her best!

It's time for a field trip to the beach, and the gang's getting ready. But who wants to see Kazuma in a swimsuit?

The field trip is here, and it's great! Everybody's at the beach and having a great time. But Tanya hears something that makes her upset...

It's time for Field Day, and Roswaal hints that whoever wins will get to go home. But then they meet their opponents...

Field Day is here, and it's lots of fun for everyone. There's tug of war, scavenger hunts... and giant robots?!

The mobile fortress "Destroyer" has joined the last game! It's up to the quartet to grab its headband and win the game.

The students have now finally settled into their new lives, but a new student has come to the school, and his name is… "Shield"?

Life's great in this world, except for one thing: there's no alcohol! When the students sneak into the principal's office to get their fix from his stash, they run into more than they bargained for.

This new world is a great place: no fighting, no danger, and the classes are easy. But you REALLY don't want to get detention!

It's time for a test! Everybody expects Ains to score highly, but… he never even passed middle school!

It's Valentine's Day, which means it's time to give chocolate to the boy you like! But an unexpected face makes an appearance…

It's time for a battle to settle the most important question of all: what do you put on your chicken wings?

It's time for physicals, and everybody's ready to get naked and get on the scale! Who will be brave enough to go peek at the opposite sex?

Visha's been working overtime lately. But what does she need the money for?

It's time for a play! But what kind of play should they put on? Filo will find out!

It's time for a school festival! But something is lurking outside the school…

The curtain rises on the school festival! There's a special guest, too…

The mobile fortress "Destroyer" has joined the last game! It's up to the quartet to grab its headband and win the game.

The class arrives in another world and they encounter a desolate environment dominated by a rampaging magical automaton.
