While struggling to make friends after his parents’ divorce, Koyomi Takasaki meets Kazune Takigawa, but apparently, they already have. Kazune reveals that she’s from World Line 85, an alternate universe in which she and Koyomi are lovers. But in a reality where moving between dimensions is natural, could Koyomi be the one from another world?
But there was no one closer to 0 than her.
Aber es gibt keine,
die näher an null ist, als sie.
Pero no hay nadie
más cercano al cero que ella.
Pero no hay nadie
más cercano al cero que ella.
Mais personne
n’est plus proche du 0 qu’elle.

 tanto vicina allo zero quanto lei.
Mas não há ninguém mais próximo
de zero do que essa pessoa.
При этом нет никого,
кто был бы ближе неё к «нулю».
