A-kun to Matsuri no Mukou

There's a strange legend at this school. One day, our protagonist went astray in the world they spoke of. You will meet both humans and monsters in this world. While the protagonist gets mixed up in the story, he remembers what he lost and regains it. A traditionally japanese-styled horror fantasy that takes place in a school. A bromance kind of story. The game takes around 7 hours to play.
