History Videogame / AoOni

[[caption-width-right:300: The titular Blue Demon.]]

* JumpScare: The cutscene when you're trapped in the jail could count. But if you really want a Jump Scare, hide in a closet with the monster in the room. [[spoiler:At the end of the game, you get one of these with a horrifying sound to boot.]]

* ScareChord: The music played when chased.

The game can be downloaded for free [[http://mygames888.web.fc2.com/aooni.html here]].

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

** {{LetsPlay/Markiplier}} is doing a playthrough now as well.

* CuriosityKilledTheCast

** Subverted in version 6. At one point, the player is in a room when something breaks offscreen, only to see a cat flee the room after knocking over a picture frame. [[spoiler:Seconds later, a monster with MoreTeethThanTheOsmondFamily and BlackEyesOfEvil runs out from behind a bookcase toward the player]].

* LetsPlay; Cry did a [[http://youtu.be/0Wr5_xbQZKc Let's Play]] of the game. In the first part, he gets mad at a NPC that is too afraid to talk, getting Cry [[BadassBoast to affirm that]] (unlike that NPC) [[TemptingFate he is a real man]]. HilarityEnsues. Note : in the first part, there is an issue about text in menues not showing up. [[ItGetsBetter It gest fixed in later videos]].

* EarlyInstallmentWeirdness: The original version puts more detail into the ExcusePlot with a longer opening sequence. While the main character is still named Hiroshi, he's now a dark-haired underclassman who, along with the silver-haired Kazuya, gets forced to visit the mansion by a gang of four older students. Takuro leads this gang, and the other members include Mika's precursor Megumi, a brown-haired Takeshi counterpart, and a gray-haired boy who would eventually become Hiroshi in later versions. There are no character portraits.

* CatScare: Subverted in version 6. At one point, the player is in a room when something breaks offscreen, only to see a cat flee the room after knocking over a picture frame. [[spoiler:Seconds later, a monster with MoreTeethThanTheOsmondFamily and BlackEyesOfEvil runs out from behind a bookcase toward the player.]]
** One of the first events in every game involves Hiroshi hearing a strange crash and going to investigate. [[spoiler:It's just a broken plate.]]

Keep in mind that with different revisions of the game may have significant differences within the plot.

* 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. Good luck trying to hide in one without the oni catching you!
* BehindTheBlack: [[spoiler: The oni seems to like hiding behind text boxes to enter a room unnoticed.]]

** In 1, [[spoiler:only Hiroshi, Megumi and Kazuya manage to escape]].

* CatScare: Subverted in version 6. At one point the player is in a room when something breaks offscreen, only to see a cat flee the room after knocking over a picture frame. [[spoiler: Seconds later, a monster with MoreTeethThanTheOsmondFamily and BlackEyesOfEvil runs out from behind a bookcase toward the player.]]

* ColorCodedCharacters: In the later games, Takeshi, Mika and Takuro have blond, brunette and red hair respectively, while Hiroshi has silver-white hair. Makes it easy to tell them apart.

* DarkerAndEdgier: Aside from [[GuideDangIt removing the more confusing and misleading puzzles]], version 6 amped up the horror elements compared to the previous one, changing the attic from just another location to get puzzle pieces into an EldritchLocation, including the gut-punching ScarySurpriseParty scene, and [[spoiler: sequentially killing off the other characters one by one.]]
* DrivenToSuicide: [[spoiler:Takeshi, in version 6. He is extremely sad, and guilt-ridden after convincing everyone to go into the mansion, only for most of them to get eaten, killed, or worse.]]

* DwindlingParty: In some versions, including [[spoiler:1, 3 and 6]].

* GoryDiscretionShot: Used in conjuction with ShadowDiscretionShot for one death: [[spoiler:after seeing a shadow pass by a screen door, attempting to enter five times will let Hiroshi actually go in, while the 'camera' stays out in the hallway]].

** Quite possibly part of the reason Takeshi [[spoiler:Kills Himself]] in the middle part of the game, to prevent the Onis from doing this to him. [[spoiler: It doesn't work.]]

* MorphicResonance: In Version 6, [[spoiler: After your friends die, they turn into monsters that look exactly like the original monster except they retain the hair and hairstyle they had as humans.]]
* 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.

* RoomFullOfCrazy: In 6. It doesn't appear until you [[spoiler:hide in the cupboard there]], however.

* 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

* ThisIsNoTimeToPanic: In 3, Takuro chastizes Takeshi and Mika for arguing and tells them this.

* TwistedAnkle: Takuro, in version 6. He hides in a closet, and gives you an important item, later on, you will come to collect him, [[spoiler: but the monster ate the rope ladder you need to escape, and chases you and Takuro, he trips over and is eaten/killed/whatever you call it...]]

* HumanoidAbomination: The Ao Oni.

** The 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]].

* SillinessSwitch: If you enter "SOUTHPARK" as your name, the character sprites are drawn in ''SouthPark'' style and the dialogue is changed to incorporate catchphrases from the show. ''"Oh my god, they killed [[spoiler:Mika!]] You bastard!"''

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

* ScareChord: the music played when chased.
