Aooni The Blue Monster
Ao Oni ~The Animation~ (JP)
Season: Fall 2016
Premiere Date: October 2, 2016


Ao Oni began as a freeware horror video game made with the RPG Maker XP program. Released by noprops in 2008, the game’s popularity inspired a three-volume light novel series in 2013, a manga anthology in 2014, and two live-action films in 2014 and 2015. Aooni The Blue Monster (Ao Oni ~The Animation~) is a series of comedic shorts. A 3D feature-length film based on the franchise will premiere in 2017. The original game is available to play for free in Japanese, English, and Italian.


There were rumors of a monster appearing in an abandoned mansion on the edge of town. Takuro–along with his classmates Takurō, Takeshi, and Mika–go to the mansion and are attacked by the monster, called the “Ao Oni” (lit. Blue Demon). Will the team be able to solve a multitude of mysteries and escape the mansion? Or…

Will they continue to live a hilarious and crazy life with the Ao Oni in the mansion!? The courage-testing life of four kids and their crazy antics with the Ao Oni begins.


Voice: Ryōta Ōsaka


A boy who has the aura of a protagonist and thinks scientifically. He’s always cool and calm, and is the brains of the group. However, his speed when running away is unparalleled.

Voice: Takahiro Mizushima


A boy who looks like the protagonist from his looks alone, but is in fact just a party-loving dude. Although he’s the one who sets the mood of the party, he also has a tendency to look down on others and is a bit overbearing. For some reason, he thinks that vinegar solves all of life’s problems.

Voice: Eri Kitamura


A girl who’s ranked as third cutest in her class. She agreed to participate in the test of courage despite being a coward because of her ulterior motive of wanting to get close to Takurō. She’s the self-proclaimed heroine of the group.

Voice: Shūta Morishima


The biggest coward of the group, Takeshi regrets his decision to join the test of courage. A lovable idiot who is hard to hate, even when he lashes out at the other members or makes nasty comments due to his fear.

Ao Oni


A naked, blueberry-colored giant who appears in the abandoned mansion at the edge of town.



He’s fast.
