Step into the chilling shoes of Kasuga, a popular student who awakens to find herself inexplicably locked inside her high school after dark. The familiar halls are now eerily silent and shrouded in shadows, a stark contrast to the lively environment she knows.

With no memory of how she got there, a desperate need to escape fuels her exploration of the seemingly abandoned building.

As Kasuga ventures deeper, the terror escalates. Her smartphone buzzes with cryptic messages, and strange entities begin to manifest, blurring the lines between reality and nightmare.

To break free from this spectral prison, she must meticulously piece together the fragmented truths about her school, her classmates, and even her own identity. However, be warned: the secrets buried within these walls are far more sinister than they appear, and nothing is as it seems.

This psychological horror adventure plunges players into a narrative-driven experience where exploration and puzzle-solving are key to survival. Unraveling the mysteries of the haunted high school requires keen observation and a willingness to confront the darkness that lurks within.
