Itsuki and Chizuru have formed a new unit of their own. Chizuru is certain it'll work out well since they're such good friends, but Yuzuru warns him that he may soon start to think of Itsuki as an enemy. Meanwhile, Itsuki becomes busy with his new work on the side...

Una unit no funcionará
solo porque seáis amigos.

Un groupe, c’est pas si simple.
Non basta essere amici 
perché un gruppo funzioni.
Um grupo não é algo tão simples que 
 daria certo só por vocês serem amigos.
