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.
You started owning this 
upperclassman thing all of a sudden.
.لكن، بدأت في التصرّف كطالب أكبر سنًّا فجأة
Ich mein ja nur! Du hast dich auf einmal
richtig wie ihr Senpai aufgeführt.
Es que te comportaste como todo
un superior. Fue tan divertido.
Tu t’es mis à agir comme un mentor,
Voglio dire, all'improvviso hai iniziato 
a comportarti come un vero e proprio senpai.
Mas você de repente começou a
fazer pose de senpai e tudo mais!
Но ты так умничать
начал перед ними.
