[Machine Translation] An endless expedition in a soul-chilling world - a girl is trapped in a ghost story of sunset. Yuni-Yuoni-" is a first-person horror game set in 1990s Japan. A girl who has created a shell in her mind without realizing it is there, is forcibly invited to participate in a "test of courage," and is taken away to the world of sunset by a ghost called Tsun, who forces her to play a game of tag called "Yunoni. In the evening world, the girl is attacked by a shadowy human and a monster with eyeballs... She spends her days running for her life from the monsters in the evening world. Soon, the strange things begin to appear in the real world as well. And then there is a girl... The first half is a test of courage, the second half is a game of tag. The first half of the game is a test of courage to find the goal doll, and the second half is a game of tag to escape from terrifying enemies. Players can only hide and hold their breath. Quick decision and action are the key to survival. The game design invites nostalgia and fear with an evening theme: a scary game held in a different space composed of a school building, a hospital, and a Japanese house dyed in the setting sun. The story, which consists of five chapters, is more than just a "school ghost story"; it offers a rich worldview that adults can enjoy as well. In between chapters, the story and worldview are supplemented with text, just like a novel game.
