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.
You shall exult in your lives!
!ستبتهجون في حياتكم
Ihr werdet in der Lage sein,
euch eurer Leben zu erfreuen!
y cantarán odas a la vida misma!
et pourrez profiter à fond
de votre existence !
e potrete tornare 
a esultare delle vostre vite!
poderão exultar suas vidas!
и сможете наслаждаться жизнью!
