It's Ruka's birthday, and Kazuya has to stay true to his word and grant her anything she desires. But what does she want, really?
but my main motive was to
not leave the two of you alone.
لكنّ دافعي الرئيسيّ كان عدم ترككما بمفردكما
aber ich machte mit, weil ich euch beide
nicht miteinander allein lassen wollte.
pero mi principal motivo
era evitar dejarlos a solas.
pero mi principal motivo
era evitar dejaros a solas.
mais c’était surtout
pour vous empêcher d’être ensemble.
पर मेरा मकसद तो तुम दोनों को
अलग करना था।
ma forse il vero motivo era 
che non volevo lasciare voi due da soli...
mas o meu principal motivo foi
não deixar vocês dois sozinhos.
но стала помогать,
только чтобы не оставлять вас вдвоём.
