Ryūsei, a college student, saves a cosplaying girl from an attacker on Christmas night, only to be stabbed and nearly die. He awakens to find the girl, Yotsuba, claiming to be a demon summoned by an unknown person, and their lives are now bound together. They must find the summoner within a year to grant a wish, or both will perish. As they search, Ryūsei’s ability to see the past and his own emotional scars shape their journey. The pair navigate their forced connection, growing closer while facing supernatural challenges and Yotsuba’s demonic nature.
