Synopsis

What if the entire universe was inhabited by echoes of the exact same person? Torn from his reality, Katsu discovers a bizarre multiverse where every single world belongs to a different version of a girl named Kira. Powerless and stranded in the unknown, his only hope of finding a way home relies on the Kira who first found him—and her countless other versions. The catch? A dark and powerful variant is willing to shatter entire realities to achieve her goal, and Katsu is the ultimate key to her plan.
