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.
Don't run your mouth
more than you have to!
!لا تتحدّث أكثر ممّا ينبغي
Plauder nicht ständig mehr aus als nötig!
¡No le digas eso!
Ne dévoile pas les détails !
Faresti meglio a tacere!
Não diga coisas desnecessárias!
Не болтай лишнего!
