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.
Bind yourselves with an eternal vow
 and become forever one of us!
!اختموا أنفسكم بعهد أبديّ وكونوا جزءًا منّا إلى الأبد
Bindet euch selbst mit einem ewigen Schwur
und werdet auf immer ein Teil von uns!
¡Hagamos un juramento eterno
y seremos uno para siempre!
Passez ce serment éternel et rejoignez
notre communauté d’immortels !
Stringete un vincolo eterno
e unitevi a noi per sempre!
Façam seus votos eternos e
tornem-se um de nós, para sempre!
Свяжите себя вечной клятвой
и станьте одним из нас навеки!
