Lockdown Zone: Level X Plot
Ryoka is awakened by flurry of text messages from her mother! Panicked and rushed, Mom is clearly concerned for Ryoka’s safety but she is not to keen on letting her daughter know why. And the reason behind that is nothing could really properly describe what is happening! The world might be ending! And there might be an unidentifiable being on the roof of their apartment building!
