We can all pretend we're Onii-chan's 
little sisters and go on a date with him.
Wir können alle so tun, als wären wir
Onii-chans kleine Schwestern, und mit ihm ausgehen.
¡Todas fingiremos ser sus hermanitas
Todas fingiremos ser sus hermanitas
On va sortir toutes ensemble
dans la peau de sa sœur.
Possiamo fingere tutte di essere sue sorelline
e uscire insieme a lui.
Podemos todas fingir
sermos irmãzinhas dele
Давайте все притворимся 
его сёстрами и сходим с ним на свидание!
