Synopsis

Sixteen-year-old Yuri Honjou watches a man get his head split open with an axe, then bolts in terror from the masked killer—only to realize she's trapped inside an abandoned building with every door sealed shut. She makes her way to the roof hoping for escape, but finds nothing but a dead, empty cityscape hemmed in by tall buildings. It's bleak, but then she discovers her brother is trapped here too. That gives her purpose: find him and get out. Things get worse. There are more masked killers roaming around, and they're clearly enjoying themselves—killing and doing whatever they want to their victims. Now Yuri has to figure out if either of them will make it out alive.
