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.
Oh, I'm sorry.

Ah, bitte entschuldige …
Ah, désolé.
C’est plein, aujourd’hui.
Oh, mi dispiace.
Ah, desculpa.
А, прости.
