Amrita no Kyouen

On the way home from school, Tamahi and several classmates see someone fall from the roof of a nearby apartment building. They rush inside expecting to find the victim or someone who can help, only to discover a place that feels impossibly deserted, with no clear trace of what they just witnessed. The deeper they move through the building, the stronger Tamahi's sense becomes that something is watching them from the empty spaces around them. What should have been a straightforward accident turns into an encounter with a presence that refuses to reveal itself fully, and escaping the building becomes harder than understanding what is inside it.
