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.
Issei, you're such a nice guy!
!إيسّي، يا لك من شخص طيّب
Issei, du bist ja ein netter Kerl!
¡Eres tan dulce, Issei!
Issei, sei così caro!
O Issei é tão bonzinho!
Иссэй, ты такой хороший!
