Appearance Edit

The Oni is a tall, blue/purple-ish (violet) creature with a large head. Ao Oni's face is nearly identical to that of a human, sans proportion-wise. It bears a large downwards-projecting nose and two enormous eyes. The body seems to have no hands save for a few certain cut-scenes in which hands do appear up close. Its body lacks for the most part, any defining features. Being mostly smooth with minimal detail. The Oni usually has the same bemused expression on its face. The back of the Oni's head is black, suggesting either dim lighting, or possibly even hair.

Surprisingly, it seems to be able to open its mouth unusually wide; almost half the size of its head, as seen in the very end of the game.

Story Edit

The Oni is an enigmatic, mysterious creature that lives in the abandoned mansion on the outskirts of a town in Japan. Not much is known about the Oni, but it lives with many creatures that resemble it. It is known to feed upon people that enter the mansion. In Version 6.23 it has been shown that after the Oni kills, the victim becomes an Oni themselves. It seems to act like a virus, when the "virus" interacts with a sentient creature, within moments it can turn them into a horrific monstrosity, as an example with a pregnant cat in the original game.

Chases Edit

One of the main elements of the game are the chase sequences. At certain times, the Oni will appear and head for Hiroshi, following him from room to room. The Oni moves only slightly slower than Hiroshi, making him somewhat easy to outrun. After a set amount of time, the oni will cease chasing and disappear - only to randomly reappear in an entirely different and unpredictable location in the mansion. In Version 1.0 it takes the longest to outrun him.

Oni chasing hiroshi

The main fright to these chases are the randomized and unexpected pattern of appearances the Oni will make over the course of the game, and the bizarreness of its appearance. Certain chase sequences are scripted chases, meaning they are part of the story, and will inevitably happen during every playthrough of the game. An example of this is when the Oni appears in the library after Hiroshi picks up the key on the table. All other chase sequences are random chases, meaning they are unpredictable and happen in a different order during every playthrough of the game. There are a large number of open doors and closets in the mansion that the Oni has the ability to enter, and the player must constantly be aware of these. 

In Version 6.23, most chases last somewhere between eight and ten seconds. To outrun the Oni, you must evade him until the timer runs out, and then leave the room. In earlier versions, the Oni will instantly disappear when the timer runs out. It should be noted that at times, the Oni is also able to get the jump on its victims and move at a speed that will result in the player automatically getting a game over. This is only demonstrated across all versions when Hiroshi attempts to pick up the key to the basement without closing the jail cell door and a unique example is present in Version 3.0 if the player selects the option to escape alone, which will trigger the Oni and result in a game over.

Ao Oni (2014 Movie)Edit

When the group of kids enter the jailhouse they hear instances of such a creature living within the building. The Oni manages to kill both Takeshi and Mika which further proves that they are not alone in the jailhouse, Shun and Anna hear the cries of Mika behind a door and Shun goes to it, but something on the other side breaks the door down....Then, a rather tall humanoid demon appears and mocks Mika's cries for help. The Oni gives chase and Shun and Anna escape the creature and meet up with Hiroshi. The Oni kills off Takuro and then chases Anna and Hiroshi succeeding in running over Hiroshi and gives the final chase as Anna hides in a bedroom, the Oni repeatedly calls her name in the voice of Shun's while hitting the door. When she walks into the door the Oni disappears and it is unknown of the whole event, including if the Oni even existed.

Etymology Edit

Oni (?) are a kind of yōkai from Japanese folklore, variously translated as demons, devils, ogres, or trolls. They are popular characters in Japanese art, literature, and theatre. Depictions of the Oni vary widely but usually portray them as hideous, gigantic ogre-like creatures with sharp claws, wild hair, and two long horns growing from their heads. They are humanoid for the most part, but occasionally, they are shown with unnatural features such as odd numbers of eyes or extra fingers and toes. Their skin may be any number of colors, but red and blue are particularly common. They are often depicted wearing tiger-skin loincloths and carrying iron clubs, called kanabō (金棒?). This image leads to the expression "oni with an iron club" (oni-ni-kanabō (鬼に金棒?)), that is, to be invincible or undefeatable. It can also be used in the sense of "strong beyond strong," or having one's natural quality enhanced or supplemented by the use of some tool.[1] Via the same character used in a Chinese context however, the kanji 鬼 may also translate to a ghost.

Gallery Edit



  • In the Ao Oni Ver.2.0 trailer in the end clip we see a giant "Godzilla" sized Oni leaning over the jailhouse and growling at the camera, it is unknown if this is the same enlarged Oni or a totally different creature set to appear in the sequel.
  • In the game the Oni has infrared vision, however in the 2014 movie adaptation he has a normal vision.
  • The Oni's voice is briefly heard in one of the versions but as an unidentified whispering sound, in the movie the Oni talks full Japanese and can also mimic the voices of others to fool its victims.
  • The Oni's relationship with the other Oni creatures that appear is unknown, which may be either failed cloning experiments or relatives.
  • It is physically illogical that the Oni can fit through doors in the mansion with its huge body and head.
  • The Oni can inject a virus that would turn anyone into Oni by touch. Hiroshi's friends are examples.
    • Oddly, Takeshi turned into an Oni despite the fact that he comitted suicide.
  • The Oni is neither intelligent nor unintelligent.
    • He has shown his intelligence by surprising Hiroshi in some occasions (jumping out from the closet, waiting for Hiroshi to come close to his hiding spot, etc).
    • Although The Oni itself hid inside a closet, it seems incapable of spotting Hiroshi in one (Should he be fast enough).
  • It is still unknown if The Oni is the owner of the mansion or the owner of the mansion were killed by The Oni.
  • The Oni's action of chasing the player is nothing more than chasing the player out of the mansion.
    • Evidence is that he stops chasing the player after he/she gets out of the mansion (at the end of the game) or when the player hides from him (due to his infrared vision, he can't see the player if hid inside an object), hinting that he doesn't want humans to be in the mansion (or for the mansion to be explored).
