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?
That destination was this world, your world.
Das war die Welt, in der Sie jetzt leben.
Resultó ser tu mundo.
Resultó ser tu mundo.
C’est-à-dire, le monde dans lequel
vous vivez actuellement.
La scelta ricadde sul tuo mondo,
 quello in cui vivi tu.
E esse alvo é o mundo
em que você vive agora.
И в итоге остановились на мире,
где сейчас живёте вы.
