To Every You I've Loved Before

Koyomi Takasaki finds himself grappling with loneliness and the challenges of making friends following his parents' divorce. His life takes an unexpected turn when he encounters Kazune Takigawa, who claims to already know him. Kazune reveals she originates from World Line 85, an alternate universe where she and Koyomi are romantically involved. The revelation throws Koyomi into a world where interdimensional travel is commonplace. As he processes this information, Koyomi begins to question his own origins. Could he, in fact, be the version of himself from a different world, navigating a reality not his own? The anime explores themes of identity, connection, and the complexities of love across different dimensions.
