High-Rise Invasion

Sixteen-year-old Yuri Honjou is thrown into panic after witnessing a man killed with an axe. Fleeing a masked attacker, she ends up inside an eerily empty building where every door is inexplicably locked. When she reaches the rooftop, Yuri finds herself in a silent, lifeless landscape of towering skyscrapers with no clear way down or out.

The shock turns into resolve when Yuri discovers her brother is trapped in the same strange place. Determined to find him and escape, she pushes forward—only to realize the area is crawling with masked killers who hunt and torment anyone they come across, forcing Yuri to confront how slim their chances of survival may be.
