'Blue Demon') is a 2014 Japanese horror film based on the 2008 video game of the same name.
Anna, his sister, sees a boy named Shun being bullied by Takuro and his friends when she goes to place flowers at his grave.
Takuro, Shun, Mika, Takeshi, and Hiroshi decide to investigate an empty house.
The group hears Takeshi's scream and rush back to see him dragged backwards into the room.
Anna tells the others how she believes her brother's death was not suicide but murder.
Takuro plans on killing Anna since she knows too much, but is suddenly caught by the Ao Oni.
During its run that month, a limited number of commemorative Ao Oni-themed greeting cards were given to cinemagoers.
As well as Ao Oni, this time the film also utilized the character "Blockman" (in the Japanese original, "Fuwatty") from the video game.
