After the failure I♥B experienced in their latest live performance, they've dedicated themselves to practicing. When a senior IChu unit, Lancelot, appears before them, I♥B performs a song perfectly at their request, but the word that comes out of Issei's mouth is one they never expected.
And I couldn't get in any time 
yesterday because of that guy.
.ولم أستطع التدرّب البارحة بسبب ذلك الشخص
Und gestern bin ich seinetwegen
nicht dazu gekommen.
Por culpa de ese tipo,
ayer no pude hacerlo.
À cause de l’autre,
j’ai pas pu m’exercer, hier.
E ieri non ho potuto per colpa di quel tizio.
E não pude praticar ontem
por causa daquele cara.
Вчера не смог из-за одного парня.
