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.
come on, give it to me louder, 
that Cute Voice
هيّا أعطني إيّاه بصوت أعلى 
ذلك الصوت الظريف
also lass sie mich lauter hören,
deine niedliche Stimme!
Fammela sentire più forte, Cute Voice
Vamos, me dê uma voz mais alta e adorável
Пусть зазвучит громче милый голос.
