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.
Overcoming them brings 
a sense of togetherness
التغلّب على ذلك يعطي شعورًا بالاتّحاد
Wenn wir sie dann lösen,
fühlen wir uns einander verbunden.
Superarli crea un senso di unione
Superá-los traz uma sensação de união
зато после них — чувство единения.
