It's time for the school cultural festival! Excitement is in the air as life seems to be back to normal for Seiji, Akane, and the rest, but all is not what it seems. Shikimi suddenly has transferred into Seiji's class and it now has Akane on edge. When its decided that their class will be putting on a play with Shikimi in the leading role of the princess Akane is roped into playing the prince while Guri gets to play the rival pirate to the prince. On top of all this even Yuzu has started acting strangely and Seiji finds himself stuck in the middle, as always.
Well, we want to prove beyond a shadow 
of a doubt that we're a couple, right?
Hör doch mal! Als Pärchen können
wir alle möglichen Zweifel zerstreuen.
Les mostraremos a todos
que somos pareja, ¿no?
Les demostraremos
que somos pareja, ¿no?
Eh bien, il faut lui montrer
que notre amour est à toute épreuve.
Beh, dobbiamo provare che siamo una coppia,
senza lasciare spazio a dubbi, giusto?
Bom, precisamos provar que somos 
um casal, sem sombra de dúvida!
Ну, мы же хотим доказать, 
что мы без всяких сомнений — пара, так?
