Kamuro Aya, Miyaji Mahoro, Hinakura Riko, and Yomine Miharu all chase a balloon only to end up in their lesson room.
Suddenly seeing the four gathered like that, CEO Masaki smiles a smile full of meaning and says that "It's all inevitable."
Meanwhile, Aya is taking care of a weakened little cat.
Judging from its surgery wounds, Mahoro deduces that it's not a stray cat, but a lost pet.
Thus begins the search for its owner, but having grown attached to the cat, Aya can't quite put her heart into the search
We don't know why, but we all 
started going after this balloon.
.لا نعلم السبب، لكن قمنا بمطاردة هذا البالون جميعًا
Ich weiß nicht, wieso, aber wir
sind hinter dem Ballon hergerannt.
No lo sabemos bien, pero acabamos
persiguiendo este globo…
No lo sabemos bien, pero acabamos
persiguiendo este globo…
J’ignore pourquoi,
mais on s’est mises à suivre ce ballon.
Non sappiamo perché, ma ci siamo messe
a inseguire questo palloncino.
Não sabemos bem o motivo, mas
começamos a perseguir esse balão.
Мы почему-то все погнались 
за красным шариком.
