Heta Oni is a fanmade Axis Powers Hetalia game told in RPG format, based on the horror game Ao Oni.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 here and here. A playable English version can be found here.
Adult Fear: When China first comes into the mansion, he finds 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.
And I Must Scream: Italy 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 pretend to be excited each time.
Anyone Can Die: Hence why Italy has to go back in time to save everyone. However, America states that England dies the most due to the fact 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.
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: Italy suffers from this a lot. Naturally, when you're the 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.
America is going through this too. 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.
Cassandra Truth: With Italy's 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.
Cast from Hit Points: Implied with 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? Well, they can now.
Chekhov's Gun: The broken plate piece.Also, the cell in which America, France, and Prussia are trapped at one point becomes important when Italy locks everyone inside.
Italy's Bible? Yeah, that's important.
Chew Toy: Out of everyone in the series, England has it worse than everyone. 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.
Especially Part 17 1/2, considering the year and a half (and still ongoing) hiatus the author has put on this series. But with the recent Japanese earthquake affecting her, it's quite understandable.
Cowardly Lion: Italy's circumstances force this development on him because no matter how many tries it takes, he refuses to leave that mansion until he can get everyone out alive, even his enemy countries.
Declaration of Protection: America tells this to England after his previous self sacrificed himself to save him. Sadly it doesn't work and England saves him again to his horror.
The Fog of Ages: Subverted with 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 and that phrase takes a whole new meaning...
I Choose to Stay: After sending Italy, Germany and America back to their timeline 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.
Ironic Echo: At the beginning, America told Italy to smile naturally because it was obvious he was either lying or worried.. Later on, Italy tells America the same thing after he sees past England sacrifice for him and he's worried about the present time England.
Kill 'em All: Zig Zagged, because the monster succeeds in doing so, except for Italy, but then Italy gets the monster to send them back in time, but the same thing happens. Over. And Over.
The Messiah: Possibly Italy, seeing as even though he finds England and Russia unpleasant, he doesn't really hate them.
The icons, as well as Incredibly Girly Japan, are Hetalianized versions of the ones from Ao Oni — 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.
Stepford Smiler: 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.
Survivor Guilt: The first time through the house, Italy is the only one to leave.
Taking You with Me: England seems to have made a habit out of exploding to take out the Greys.
Talking Is a Free Action: The characters can have long dialogues with one another while the Tony-look-a-like monster only gets to them step by little step.
Tempting Fate: Any time anyone talks about the future. Ever. In fact, it's pretty much a sure-fire way to ensure death.
Took a Level in Badass: England. Oh, England. Especially when he gets his powers back. Everyone else probably counts, as well.
The most jarring example would maybe the Italy brothers, like gun toting Mafia!Romano and not as cowardly Italy.
Too Long; Didn't Dub: 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.
Trust Password: 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.
Unusually Uninteresting Sight: 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.
