Yui Furukawa is an enigmatic girl who was first discovered unconscious and unclothed within the old school building. She subsequently enrolled as a transfer student and joined the Astronomy Club, blending into campus life with a calm and polite demeanor—though she often appears surprisingly unfamiliar with ordinary social conventions. Behind her mysterious exterior lies a stunning truth: she is a synthetic being crafted by Kanade Akiyama and others from the future, dispatched across repeating temporal loops with the sole purpose of preventing a fatal traffic accident from claiming Kaori Sasaki's life.
