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.
I think it has something to do 
with the fact that he's writing the music.
.أعتقد أنّ للأمر علاقة بكونه ملحّن موسيقانا
Ich denke, das hängt damit zusammen,
dass er ein Komponist ist.
De seguro influye el que él
componga las canciones.
Credo... sia una conseguenza
dell'essere un compositore.
Acho que está ligado ao fato
dele está compondo as músicas.
Думаю, это связано с тем,
что он ещё и композитор.
