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.
As a demon lord, 
I have infinite time on my hands...
.كوني سيّدًا شيطانيًّا، فلديّ وقت لا نهاية له
Ich als Dämonenkönig verfüge ja letzten Endes
über eine unbegrenzte Lebensspanne,
Un rey demonio como yo vive eternamente,
En tant que roi démoniaque,
mon existence n’a pas de fin,
In quanto Re dei Demoni,
godo di vita eterna, ma...
Como o Rei Demônio, eu tenho
tempo infinito para viver, mas...
У меня как короля
демонов времени полно, но...
