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.

Mein Kopf bringt mich noch um …
Me duele la cabeza…
Ma tête va exploser…
Che mal di testa...
Minha cabeça dói...
Моя голова...
