#7Amrita no Kyouen
The Feast of Amrita
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.

#5Yami Shibai 11
Theatre of Darkness: Season 11
The horrors revolve around one idea appearing in many different forms: return. An old connection reappears after twenty years, a renovated home carries something its past never released, a music box somehow finds its way back to the same place, and memories thought finished begin standing in front of people again. In alleys, houses, train stations, and lonely campsites, ordinary people enter situations that seem familiar until one impossible detail makes retreat impossible. Sometimes the most frightening thing is not encountering something new, but realizing that what you were certain you left behind has found its way back to you.

Balloons shaped like human heads drift above a city, each trailing a noose that searches for the person whose face it copies. The strange Hikizuri siblings attempt to summon a dead spirit and invite something they do not understand, while Souichi fills the lives around him with nails, curses, and jokes that can become nightmares without warning.Elsewhere, Tomie refuses to stay dead the way a human being should, using beauty and other people’s obsession to create cycles of jealousy and murder before returning again. Dead-end streets, hair growing where it should not, ice cream hiding something revolting, and statues that refuse to remain still all follow the same cruel pattern: something familiar is pushed one step too far, then another, until it becomes difficult to remember why it ever looked ordinary.
