History Videogame / AoOni

* LovableCoward: Takeshi and Mika, but mostly Takeshi. He is found hiding in wardrobes twice throughout the whole game, and is the only person having doubts about going to the mansion in the first place.

* HelloInsertNameHere: Hiroshi, though only in version 6.20 on.
** Also somewhat downplayed, since you don't talk to the others very often. [[spoiler: Especially after they turn into Oni.]]

* NothingIsScarier: In version 6, there's no music except for when a monster appears, which is a repeating ScareChord. Also, at some points, the player has to hide in an empty wardrobe in the bedrooms; the screen goes black and the music is silenced. The only thing you can hear is the door opening when the monster enters to find you, then the door closing once it leaves. Even worse, in some cases, the monster will appear in the room just before you enter the wardrobe, thus causing a Game Over.
** Another way the monster messes with you is [[spoiler:in very rare occasions the monster even pretends to leave, sounding the door, but then when you leave your hiding spot it's still in the room.]]

* LeaningOnTheFourthWall: The monster will, at times, [[spoiler:use the text boxes to its advantage]]. In version 6, [[spoiler:not even the status screen is safe!]]
** The ''WesternAnimation/SouthPark'' spoof {{Lampshades}} this when [[spoiler:Takeshi screams at you for talking to him, because he ''knows'' the Ao Oni's been using the text boxes to pop up behind its victims]].

* FanSequel: The fangame ''Ao Oni S'' is specifically set after version 5's ending. There's also Siro Oni, Hakkyo Oni, VideoGame/HetaOni, and Crom Oni, each with, respectively, a Two Headed Oni, a Bleeding Screamer Oni, a sort of Alien-like Oni, and a Red Oni.

* DropInNemesis: The, uh, Oni.

* RaimiVision: Appears in some games; apparently, the oni sees in [[spoiler:''Film/{{Predator}}'' type of vision]].

** Some puzzles take you to a different screen to solve them. [[spoiler:During one such instance, you'll make two moves in the puzzle before it freezes... ''and the monster is suddenly walking straight towards the screen.'' And yes, he's right behind you when you return to the normal map.]] Needless to say, it's a tad unnerving.

* ConscienceMakesYouGoBack: In version [[spoiler:1]], this happens near the end of the game: [[spoiler:Kazuya escapes, but goes back looking for Hiroshi]].

The game can be downloaded for free [[http://mygames888.web.fc2.com/aooni.html here.]] There is also a sequel game simply titled ''Ao Oni 2'', in which it and the prequel are also available for Android. A two-volume novel adaptation appeared 2013. [[http://www.aooni-movie.com A theatrical film version followed in 2014,]] [[https://www.youtube.com/watch?v=4fxHUEc11TQ the trailer for which you can see here]]. A second movie unrelated to the first, ''Ao Oni 2.0'', was released in 2015. There's also a BlackComedy anime shorts adaptation by Creator/StudioDeen, ''Aooni the Blue Monster'', which aired during the summer 2016 anime season.

* AwesomeButImpractical: There are closets in a couple of rooms. You can escape the oni by hiding in one of them. If the oni is in the same room as you, going in one will land you an automatic game over (your hiding spot is no good when the oni ''sees you go in''). Good luck trying to hide in one without the oni catching you!

* ShoutOut: Right below, once you reach the part ''where [[spoiler:Takeshi gets killed]] ''WesternAnimation/SouthPark'' Style'', they copy off of ''Gantz'' and its Buddhist Mission alien speech.

* NonIndicativeName: Despite the title of the game translating to "Blue Demon", the titular monster is more of a purple color than a blue color.
