KUROFUNE made their CD debut through a special exception, but Keigo can't deny his anxiety and struggles to take hold of something that will establish them as idols. In the midst of all this, he overhears Yuto singing a song to himself and decides that that's the ticket to their future, but for some reason Yuto isn't on board...
So the five of us swore to go 
beyond the ultimate for our fans.
لذا أقسمنا الخمسة على أن نفوق المطلق لمعجبينا
Und so schworen wir fünf uns,
dass wir für unsere Fans zum Nonplusultra würden.
Los cinco juramos ser
más que insuperables por nuestros fans.
Pour nos fans, on s’est juré
de dépasser l’entendement !
Quindi tutti e cinque insieme abbiamo giurato
di andare oltre insieme, per i nostri fan.
Então nós cinco resolvermos ser mais 
 do que superiores pelos nossos fãs.
