Set in Japan in 2020, this two-episode CG original from Craftar and Hulu Japan centers on Shin Hazama. His everyday routine, which he assumed could never change, splits open when another Shin appears, one who lived a different life in another version of Japan. With their world suddenly turned upside down, a group of boys and girls must decide what to believe and which way to go, and a fight against another world and their other selves begins.
