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?
And all thanks to you
 tackling the guy, Koyomi.
Weil du den Täter umgeworfen hast.
Gracias a que atrapaste a ese hombre.
Gracias a que placaste a ese hombre.
C’est parce que
tu as poussé ce fou.
Ed è grazie a te 
che ti sei scagliato contro l'aggressore.
Foi graças a você por dar
um empurrão no criminoso.
А всё потому,
что ты сбил преступника с ног.
