Old friends resurface in Nasa's life, as he introduces Tsukasa to his old teacher Yanagi Naoko.
It's quite all right. 
So, what should I call him?
لا بأس. ماذا أناديه إذن؟
No hay problema.
No pasa nada.
Ne vous en faites pas.
Va tutto bene. 
Quindi, come devo chiamarlo?
Está tudo bem. E então,
qual nome darão?
Ничего страшного. Так как назовём?
