Overview

About this game

Trapped in a haunted high school, Kasuga must uncover buried secrets to escape the terror-filled halls.

         

                             

Kasuga, a popular student, wakes up to find herself inexplicably trapped inside her school after dark. The eerie silence and shadowy corridors are far removed from the bustling, lively atmosphere she knows. Worse yet, her memory of how she ended up there is a blank slate.

Desperate to escape, Kasuga begins exploring the seemingly abandoned building, only to encounter chilling phenomena. Cryptic text messages flood her smartphone. Strange entities begin to manifest.

Piece by piece, Kasuga must uncover the truth about her school, her peers, and even herself. But beware: nothing is as it seems, and some secrets are better left buried.

                          

  • A Spine-Chilling Horror Adventure: Explore a haunted high school filled with eerie sights, cryptic clues, and unsettling twists that will keep you on edge.

  • Interactive Smartphone Gameplay: Use Kasuga's smartphone to log clues, capture photos, and receive unsettling messages as you unravel the mysteries surrounding her imprisonment.

  • Dynamic Perspective Switching: Experience the tension from every angle—switch seamlessly between 3rd and 1st person views to fully immerse yourself in the environment.

  • Anime-Style 3D Graphics: Dive into a world that combines stunning visuals with a deeply atmospheric setting, creating a perfect blend of beauty and dread.

Will you help Kasuga escape the nightmare... or will you succumb to it?
