Synopsis

Ryouka Tsurumi wakes up on Christmas Eve to find her entire mansion evacuated and locked down. Her mother breaks the news: there's a dangerous creature called X loose in the area. Worse, it can brainwash people and feeds on human blood to reproduce. The only other person still in the building is Shuuhei, Ryouka's childhood friend. When X attacks, Shuuhei manages to save her, and they attempt to escape the lockdown zone. They don't make it far—hypnotized humans capture them, and the creature devours them both. Ryouka wakes up again in her room. The nightmare isn't over. A different X is now after her. She realizes she's caught in a time loop. With Shuuhei, she sets out to find a way to escape the cycle and survive whatever X throws at them.
