About Ao Oni
The adolescent protagonist “Hiroshi” and his friends set foot in an abandoned mansion out of curiosity. As the horrific blue creature that dwells within that mansion begins to prey on him and his friends, Hiroshi must flee from the Ao Oni that persistently hunts him while exploring the mansion and solving puzzles in order to escape, however…

The player will control “Hiroshi”, solving puzzle after puzzle to escape the mansion while running from the Ao Oni.

About the new game “Ao Oni -Ai’s Story-”

Invited by her friend Mika, Ai goes to see the mansion rumored in her town to be a haunted house. However, when she comes to she finds that Mika is nowhere to be seen, and she is trapped all alone in the mansion where the Ao Oni dwells. Now she must explore unsettling labyrinthine rooms that change every time she enters them and find the “key to her escape” in order to return alive.

The player will control “Ai” and search for the key to their escape as they run from the Ao Oni in a mansion whose structure changes every time it’s entered. Because the mansion’s structure is constantly changing like this, players can enjoy replaying the game even after beating it once.

The New Character “Ai”

Ai is a calm-natured teenage girl who is friends with Mika. She has had an affinity for reading and learning since she was a young girl, and enjoys difficult puzzles and mystery novels. Although reluctant, she ended up visiting the haunted house when she was roped into it, half against her will, by her friend Mika. Unbeknownst to her, that house was the mansion in which the Ao Oni prowls…

Official High Speed Mode

For the first time, the dev team has implemented a “High Speed Mode” for the enjoyment of those who have cleared the game, streamers, and “let’s play” creators. It is even possible to challenge the game with the highest speed ever of “15x.”

“Ao Oni” Game Overview

The four protagonists, “Hiroshi,” “Takeshi,” “Mika,” and “Takuro,” step foot in the abandoned mansion out of curiosity.

Now, the player must escape from the mansion by solving the puzzles hidden throughout it, all while running away from the Ao Oni.

“Ao Oni -Ai’s Story-” Game Overview
