Days of Urashimasakatasen

Urata, Shima, Sakata and Senra are transfer students. They introduce themselves to their new class.

The four need to join a club, but they aren't sure it'll be easy to join an existing one, so they start a new one.

The four renovate the club room as they try to decide on the club's activities.

The four have a takoyaki party with special takoyaki.

The four see the school principal for the first time at a school assembly.

Sakata sleeps through class. Urata tries to wake him up, but...

Senra and Shima come up with a scheme to prank Urata and Sakata, but things rarely go as planned for the gang.

The tanuki on Urata's shoulder finally awakens.

A gang leader from another school arrives, demanding to see the Transfer Student Club members.

The gang opens as box, and there's a bomb inside. They can't leave the room, either.

The bomb is about to blow, and the gang still doesn't even know why they're under attack.

The four play baseball. It starts raining, and they're forced to share an umbrella.
