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.
When you contacted me out of the blue, 
I wondered what was up... but now I get it.
.عندما اتّصلت بي فجأة، تساءلت عن السبب... لكنّي أفهم الأمر الآن
Als du mich so urplötzlich angeschrieben hast,
war ich verwundert, aber jetzt versteh ich’s.
Conque para esto nos llamaste
tan de repente.
Maintenant, je comprends mieux
pourquoi tu nous as appelés.
Quando mi hai chiamato così all'improvviso,
mi domandavo come mai, ma adesso capisco.
Me perguntei a razão para ligar
de repente, mas já entendi.
Я удивился, когда ты
позвонил... но теперь я понял.
