Naho got into a fight with Kakeru on New Year's Eve, and never managed to apologize to him before he passed away. At least, that's what the letter from the future says. However, Naho now believes that she's capable of dealing with whatever may come up, and faces New Year's Eve head-on.
That's got nothing to do with this world!
!ليس لذلك علاقة بهذا العالم
Das hat in dieser Welt
keine Bewandtnis!
En este mundo eso no importa.
En este mundo eso no importa.
Ça n’arrivera pas dans ce monde !
Questo però non c'entra nulla
 con questo mondo!
Neste mundo, isso não importa!
Это никак не связано с нынешним миром!
