Synopsis
On Christmas Eve, high schooler Ryouka Tsurumi wakes in her room to learn disturbing facts. Her mother explains that their mansion has been emptied and the area placed under lockdown because of a dangerous being known as X. The only person still inside is Shuuhei Murosaka, Ryouka's childhood friend. Worse still, Ryouka finds out X can brainwash people, all to achieve its horrifying goal of drinking human blood to multiply. Shuuhei rescues Ryouka from a brutal attack by X. While attempting to flee the lockdown zone, they are overwhelmed by mind-controlled humans and subsequently devoured by the monster. But for Ryouka, this is only the beginning: she wakes up again in her bedroom and confronts another version of X threatening her. Realizing she is trapped in a time loop, Ryouka decides to join forces with Shuuhei to escape and build a safer future beyond X's influence.
