    The Four Main Students 


"So stupid... There is no way monsters can exist. It's scientifically impossible..."
The main character of the Ao Oni series, he accompanies three of his friends into a mysterious manor which is rumored to house a terrifying monster. Not that he believes in monsters, of course... they're scientifically impossible, right?


The most cowardly of the four, he immediately has second thoughts about entering the manor, though he can't convince Takuro or anyone to leave.


The natural leader of his little clique of friends. In the original version, he was also quite the bully, using the rumors about the manor to terrorize underclassmen.


The token girl of the group, she has feelings for Takuro.


The Ao Oni

The main antagonist of the game, the oni is a strange creature living in the mansion, killing people that come. He has the ability to turn other people into one of him.

Blockman Oni

A square oni that appears randomly near the end of the game.

Other Onis

There are lots of other oni creatures in a room near the end of the game.

    Version 1 Exclusive Characters 

Hiroshi (Version 1)

Unlike the Hiroshi seen in later versions, this Hiroshi is a dark-haired high school freshman who gets dragged to the mansion along with his buddy Kazuya. After being sent to investigate a strange noise, he returns to find the others missing, and sets out to track down his friend before escaping.


Hiroshi's best friend, and a prime target for the bullying Takuro. Winds up seperated from him, and thus his main motivation for exploring the manor.


A member of Takuro's gang and his Love Interest in version 1.

Takuro's Followers

Two other teenagers who round out Takuro's Gang of Bullies. One of the two, Ryota, bears a strong resemblance to the Hiroshi of the later versions, while the other serves the same purpose as Takeshi.



Another of Hiroshi's friends, a dark-haired student who only appears in one scene in certain versions: in the subverted Scary Surprise Party sequence, he's the guy in the oni suit.
