''Heta Oni'' is a fanmade ''Manga/AxisPowersHetalia'' game told in RPG format, based on the horror game ''VideoGame/AoOni''. Since its creation, most fans have heard of/played/or watched the game.

It begins where Italy hears of a haunted house, tells America about it and they bring the rest of the Axis and Allies, along with Prussia and Canada, to investigate. As it turned out, a monster resembling America's alien friend Tony begins to hunt them and they have to do what they can to stay alive.

Translations for the script and the subbed videos for the game can be found [[http://gemini-artemis.livejournal.com/72515.html here]] and [[http://www.youtube.com/watch?v=509lzLd7t2Q here.]] A playable English version can be found [[http://pianodream.deviantart.com/art/HetaOni-ENGLISH-PROJECT-V17-1-Release-pass-tuto-341833930 here.]]

Hetaoni was sadly discontinued in 2011 due to the Japanese Tsunami. The creator, Tomoyoshi, lost all the data for her project and did not want to remake the entire game again.

!!''Heta Oni'' contains examples of:

* AccentUponTheWrongSyllable: [=YoU...WOn't...ESc...aPe.=] It's probably done for effect.
* AdultFear: When China first comes into the mansion, he finds [[spoiler:Japan's clothes in the fireplace, covered in what seems to be blood. It turns out nothing happened to Japan,]] but China is still horrified at the idea that his brother was hurt.
* AmateurSleuth: To the surprise of many, [[spoiler: Canada is this]].
* AndIMustScream: Italy [[spoiler: is continually using the journal to go back in time, to save everyone. However, this always seems to have the adverse effect, as they just protect Italy anyhow, and all die as a result. Italy knows that this will happen, and he can do nothing to stop the flow of time, so he has to [[StepfordSmiler pretend to be excited each time.]]]]
* {{Anyone Can Die}}: Hence why [[spoiler: Italy has to go back in time to save everyone.]] However, America states that [[spoiler: England]] dies the most due to the fact [[spoiler: that he always sacrifices himself to save America or goes past his limit with his magic.]]
* {{Art Evolution}}: Subverted and played straight. The icons for some of the characters (Germany, America and England mainly) have {{narm}} icons but as the game goes on, it changes so their expressions can be taken more seriously.
* {{Attending Your Own Funeral}}: [[spoiler: Italy.]]
* BackToBackBadasses: [[spoiler: Austria and Korea]]
* BearsAreBadNews: Canada's Kumajirou attack causes quite a lot of damage.
* BlatantLies: Episode 2 starts off with the following note.
-->''My apologies to those who like horror, but I made this game so that it wouldn't be very scary. Thank you for understanding.''
* {{Break the Cutie}}: [[spoiler: Italy]] suffers from this a lot. Naturally, when you're the [[spoiler: only one that survives the first time during the haunted mansion and rewind time to save everyone only to fail over and over again, naturally, you would be broken.]]
** [[spoiler: America]] is going through this too. [[spoiler: Having to be saved by England multiple times whether it's the past or the present wears him down. Especially when he decides that he's going to protect England with his life and be his hero.]]
* BroughtDownToNormal: England is unable to use his magic powers. [[spoiler: He is slowly gaining them back though]].
* BrainsAndBondage: Germany's weapon is a ''personal whip'' that is described as ''well used''. And he has a technique called ''torture''. [[ArsonMurderAndJaywalking He also has a manual on how to deal with anything.]]
* {{Cassandra Truth}}: With Italy's [[spoiler: second]] experience with the mansion, first he desperately tries to talk the other nations out of visiting, then from splitting up to explore. No one pays him any heed, because it's just cowardly Italy.
* CastFromHitPoints: Implied with [[spoiler:England, as his overuse of magic led to his death in the prior loops and to his blindness in the current loop]].
* {{Character Development}}: You know how America and Italy were told in the actual series they can't read the atmosphere? [[spoiler: Well, they can now.]]
* ChekhovsGun: [[spoiler: The broken plate piece]].Also, the cell in which [[spoiler: America, France, and Prussia]] are trapped at one point becomes important when [[spoiler: Italy locks everyone inside.]]
** [[spoiler: Italy's Bible? Yeah, that's ''important''.]]
* {{Chew Toy}}: Out of everyone in the series, England has it worse than everyone. [[spoiler: He has the highest rate of getting killed and even though he can single handedly take out the Greys, he'll go blind as a result.]]
* {{Cliff Hanger}}: Most "episodes" end with this.
** Especially with [[spoiler: Part 17 1/2]]. And due to the 2011 Japanese Tsunami, there will never be a resolution.
* CowardlyLion: Italy's circumstances force this development on him because [[spoiler: no matter how many tries it takes,]] he refuses to leave that mansion until he can get everyone out alive, even his enemy countries.
* DarkerAndEdgier: Than ''AxisPowersHetalia'', which, for all its historical context, rarely even mentions death, as opposed to [[KillEmAll this story]].
* DeclarationOfProtection: America tells this to England [[spoiler: after his previous self sacrificed himself to save him. Sadly it doesn't work and England saves him again to his horror.]]
* DiesWideOpen: [[spoiler: Italy, in the second time loop.]]
* DoesThisRemindYouOfAnything
--> '''(After Germany comes out of the armoured closet fortress he had been hiding in. With a whip. And Italy is missing).'''
--> '''Japan:''' ''[to Germany]'' Do you actually like tight spaces?
--> '''Germany:''' Well, you could say that I'm...used to them.
* EldritchAbomination: That Tony look-a-like monster thingy who keeps coming after them.
* FaceHeelTurn: Subverted [[spoiler:with Italy.]]
* TheFogOfAges: [[spoiler:Italy, since he has so many memories of the time loops that he begins to forget his past.]]
* {{Foreshadowing}}: After they break the clock with England's magic, America tells England he looks a bit unfocused and asks him how many fingers he's holding up. England is quite irritated and replies with 'Two', and that they don't have time for that nonsense. Then, we get the infamous "How many fingers am I holding" scene...
** Also, when England at one point says something along the lines of: 'I envy those who can't see...' meaning spiritual sight. Cue end of part 16 [[spoiler:and that phrase takes a whole new meaning]]...
* GoMadFromTheRevelation: What it feels like to Japan after [[spoiler: receiving a large dose of visions from breaking a clock]]
* TheGreys: What the monster looks like, having a resemblance to Tony the alien.
* GroundhogDayLoop
* GuideDangIt: If want to play the game without help, prepare to spend many hours checking every object, decoration, and UNMARKED WALL multiple times in order to progress.
* HauntedHouse: Where the setting takes place in.
* HeroicBSOD: Germany suffers one [[spoiler: in one of the time loops they were in and Italy died, saving the others.]] America also suffers one [[spoiler: in a time loop where England sacrifices himself.]]
* HeroicSacrifice: After [[spoiler: Italy dies]], England [[spoiler: sacrifices himself to rewind time to save Italy.]]
* HeroicWannabe: America is still trying to be this despite the situation. [[spoiler: Not a good thing because he almost dies by trying to be the hero and protect England.]]
* HowManyFingers: Episode 16 part 2, when America does this to a [[spoiler: blind England]].
* IChooseToStay: After sending Italy, Germany and America back to their timeline [[spoiler: England prepares to sacrifice himself to kill the monster. However, that timeline America appears and chooses to stay at England's side despite England telling him that if he didn't escape in 30 seconds, they both be dead. England ends up using his powers to save America though.]]
* IronicEcho: At the beginning, America told Italy to smile naturally [[spoiler: because it was obvious he was either lying or worried.]]. Later on, Italy tells America the same thing [[spoiler: after he sees past England sacrifice for him and he's worried about the present time England.]]
* KillEmAll: ZigZagged, because the monster [[spoiler: succeeds]] in doing so, except for Italy, [[spoiler: but then Italy gets the monster to send them back in time]], but the same thing happens. Over. And Over.
* MeaningfulEcho: [[spoiler: How many fingers am I holding up?]]
* MindScrew: So, so much.
* TheMole: Subverted [[spoiler:with Italy.]]
* MythologyGag: So many of them.
** America mentions a few times that he's "reading the atmosphere" today; earlier, in ''AxisPowersHetalia'', he was told that he was [[MomentKiller incapable of reading the atmosphere]].
** Later, when America finds his lost glasses, he exclaims, "My Texas!" - another reference to a joke in the series.
** When the characters choose human names, they use the names given by WordOfGod at fan request in bonus materials.
** The mochi in the attic is Mochi America from an earlier Hetalia thing. America notices:
--> '''America''': What is this [[StealthPun revolutionary]] creature? It radiates such an aura of intelligence!
** Canada can't be seen by enemies when he's in the same room as them; which echoes the way the other characters ignore him in the anime and webcomic.
** A DarkReprise of the anime's ending theme plays over the main menu screen, and Italy has the option to play it on the piano.
** During the chapter where you play as England and China, if you look at the throne/chair in the attic, China remarks that it looks like "a cursed chair he saw once"... which England promptly decides to ignore.
*** In the same part, the player can find England and France's marriage certificate in the bookshelves.
* NothingIsScarier: Quite a few examples. The game never tells you what, exactly, is wrong with the house, what exactly is killing the nations or why, how or why it has such an absurd degree of supernatural power, what locks them in once they enter, who the original owner of Italy's journal was or [[FridgeHorror what happened to him that caused him to leave it behind...]] And you never know [[GroundhogDayLoop how many times Italy's seen everyone slaughtered]], nor the extent of the SanitySlippage he starts to show, let alone whether he even survives.
** The death sequences are this, too; if you get killed in-game, the screen simply goes black and a horrible shrieking is heard before the "Game Over" screen appears. When Italy flashes back to his dying friends, we simply see them mangled and bleeding - not what happened to them. Unexpected and numerous NonStandardGameOver sequences go like this, too, caused by mundane actions; like a random lever that turns the whole room hellish red and starts [[HellIsThatNoise ringing loudly]] before the normal black-screen-game-over shows up, or a hole in the wall that, when you lean to far in, simply makes a gruesome squelching sound and triggers the Game Over screen again. Not to mention whenever you forget to lock the door...
** We also never find out what the voice in Prussia's head is, what Russia's mysterious phone calls are about, whose blood is splattered all over the clock and numbers rooms, what grabbed Germany's ankle, or [[ArsonMurderAndJaywalking whether the "Water?" was actually water]].
* ObfuscatingStupidity: [[spoiler: Italy]] had to do this in the beginning to seem normal, but has a few slip-ups.
* OOCIsSeriousBusiness: As soon as the Axis Powers are reunited, one of the first things the viewer (and Japan) notices is that Italy's acting incredibly OOC, later found out to be with good reason.
* RetrauxFlashback: After the ArtEvolution moment.
* SayMyName: ENGGGGLAAAAANDDDDD!
** AMERRRRRICCCAAAAAAA!
** ITALY!!
** Ve-nezianooo!!
* ShoutOut: Pretty much all of England's attacks are familiar spells like [[Literature/HarryPotter Expecto Patronum]].
** Japan's [[{{Otaku}} poster sword]] is a call back to the HetaliaBloodbath2010 [[spoiler: and a significant one if you think about it: after losing to the Mysterious Figure is when [[FridgeBrilliance Japan decides to train to not lose a fight like that ever again]]!]]
** The icons, as well as Incredibly Girly Japan, are Hetalianized versions of the ones from ''VideoGame/AoOni'' -- which was evidently made with preexisting graphic sets for the most part, hence the wildly different art styles.
** Interacting with the piano in the playable translation causes certain nations to play {{Vocaloid}} songs.
* StealthPun: Germany refuses to get out of the closet.
* StepfordSmiler: [[spoiler: Italy is a Type 1 because he knows what's going on and what happens if he fails to save everyone and America recently because he can't help but feel useless in the past and the present.]]
* SurpriseCreepy: More like Surprise Dark, but still - did you come looking for a lighthearted mystery based on a lighthearted anime? Yeah, that [[KillEmAll isn't going]] [[SadistShow to happen]].
* SurvivorGuilt: [[spoiler: The first time through the house, Italy is the only one to leave.]]
* TakingYouWithMe: [[spoiler: England seems to have made a habit out of exploding to take out the Greys.]]
* TalkingIsAFreeAction: The characters can have long dialogues with one another while the Tony-look-a-like monster only gets to them step by little step.
* TemptingFate: Any time anyone talks about the future. Ever. In fact, it's pretty much a sure-fire way to ensure death.
* TookALevelInBadass: [[spoiler: England. Oh, England. Especially when he gets his powers back. Everyone else probably counts, as well.]]
** [[spoiler: The most jarring example would maybe the Italy brothers, like gun toting Mafia!Romano and not as cowardly Italy.]]
* TooLongDidntDub: There is one particularly devilish puzzle involving traditional Japanese month names, which doesn't make a lick of sense in English. The script translator just wrote a footnote explaining what the hell is going on for that scene.
* TrustPassword: [[spoiler:Apparently the nations only made up human names in one loop, making them useful for this in the event of a timeline hiccup. Italy correctly deduces that America is from the same time by his reaction when called "Alfred"; Spain notes that England doesn't recognize the name "Kirkland" and is probably from a different loop.]]
* UnusuallyUninterestingSight: Invoked and Justified by France when two Greys attack, and Spain (who is in the mansion for the first time) screams bloody murder, in contrast to the stoicism of the Allies and Axis.
--> '''France''': See, now that's a natural reaction. I suppose we've been through this so many times that we've gotten unconsciously used to it.
* WhamEpisode: The second half of Episode 16.
