YMMV / Ao Oni

  • Big-Lipped Alligator Moment:
    • The Oni prison room in most versions of the game. The fact that you never see most of the Oni from it later in the game makes it even more prominent.
    • The Blockman Oni from version 6, as well. It only makes two appearances ( one as a chaser, and one in the aforementioned Oni prison room), and never appears again. Unless you enter "BLOCKMAN" as Hiroshi's name.
  • Fan-Preferred Couple: For some reason, Hiroshi/Takuro is fairly popular.
  • Fridge Horror:
    • To escape the mansion, you have to do elaborate puzzles that rely on items you find. At the end of the game, you see a man has gone into the mansion. He won't be able to get out because you have completed all the puzzles, so he won't be able to get the items he needs to get. Not to mention you have now let loose 3 other monsters in the Mansion...
    • There's also the large group of monsters you find in the basement, all of which mysteriously vanish after you've managed to get away from the two that were chasing you. And on top of that, you find cages, jail cells, and straight-up dungeons in certain areas of the mansion. Just what were those used for?
  • Germans Love David Hasselhoff: Ao Oni is popular with Korean bloggers that most of the spin offs can be found on Korean sites.
  • Ensemble Darkhorse: Naoki. He only shows up in one version of the game (and even then, only in a dream), but he's so popular in the fandom that he's practically become, more or less, the unofficial Sixth Ranger to the main cast.
  • Memetic Molester: The Ao Oni himself. Especially with PewDiePie's infamous "raping time" gag that he made off of it.
  • Memetic Mutation:
    • Though it only occurs in one version, Takuro's Death by Headchomp is referenced a lot in fanwork and parodies.
    • Takuro is a ninja.
    • For the Oni, we have "It's Raping Time" and "Shut up and Sleep with me".
  • Nightmare Fuel: The titular creature itself. Mostly due to its Uncanny Valley factor.
  • Nightmare Retardant:
    • Some people consider the blue monster's face to be adorable, goofy, or derpy rather than scary; it's even been referred to as blue Barack Obama. Or a japanese smurf. Maybe it's a suffocating Matsumoto? One member of a pair of Japanese walkthroughers (known as Borzoi Project) said that the Oni was kind of cute when they came face-to-face with it a second time, to which his buddy responded, "Are you an idiot?"
      slowbeef: The fuck is that, a Sesame Street character?
    • South Park mode!
    • Hindu Squato!
    • The fact that some of them appear with hair makes it look like they're wearing hilariously bad wigs.
  • Paranoia Fuel: The Onis breathing. In version 6, the heavy breathing noises of the Oni are heard throughout the Dark basement. With only a lighter, you cannot see the whole screen, and the monster could pop up from any direction.
  • Signature Scene: The jail scene.
  • That One Puzzle:
    • Let's just say that many of the puzzles in the game are very confusing and requires checking everything and using everything on everything else.
    • Version 5 in particular suffers from this due to the Cipher Puzzle. It requires knowledge of a Japanese abacus (a Soroban) and how to count using it. The English and German translator actually left a note saying they're stumped on how to translate it better for western players, and that looking it up is really the only option.
  • Uncanny Valley: The monsters.
  • What an Idiot!: In version 6, Hiroshi finds Takuro after apparently being killed by the Oni, in the Oni prison room, having appeared out of nowhere. Oh sure, bring him along, What Could Possibly Go Wrong?
