About this game
Tokyo. On the eve of the year 2000.
The office tower of Kurobaito Systems stands empty beneath endless rain.
The power is still on. The computers still boot.
But the people are gone.
You find yourself inside a building where the past seems trapped between floors.
Explore offices, corridors, and technical areas, gradually unlocking access to new zones.
Boot up old PCs, read employee records, uncover traces of presence — and piece together the chain of events that unfolded within these walls.
There is a sense of something else inside the building.
Sometimes in movement. Sometimes in sound.
It is not always visible — but you are not alone.
Features:
Minimalist design with a focus on atmosphere rather than action
Tension built through presence and the unknown
Slow-paced exploration and gradual area progression
Environmental storytelling through documents and forgotten technology
