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
And last, but certainly not 
least, is me, Hinakura Riko!
!وأخيرًا، أنا هي هيناكورا ريكو
Und zu guter Letzt ich,
Hinakura Riko!
Y para cerrar, yo, ¡Riko Hinakura!
Y para terminar, yo, ¡Riko Hinakura!
Et en dernier, c’est moi,
la seule et l’unique Riko Hinakura !
E l'ultima, ma di certo
non meno importante, sono io,
E por último, mas não menos
importante, eu, Hinakura Riko!
И последняя, но не 
по значению, Рико Хинакуро!
