Lockdown Zone: Level X

監禁区域レベルX

On Christmas Eve, high school student Ryouka Tsurumi wakes up to frantic messages from her mother. She learns her apartment building is under a mysterious lockdown due to a dangerous entity known only as X, which brainwashes people to feed on human blood. Ryouka and her childhood friend Shuuhei Murosaka are the only ones left inside.

As they attempt to escape, they are captured by hypnotized victims and meet a gruesome end. However, Ryouka awakens again in her room, realizing she is trapped in a terrifying time loop. Each reset brings a new iteration of X, forcing her and Shuuhei to repeatedly confront the horror in a desperate search for a way out.
