Nira Oni is an English #fangame made during Summer 2012. The game features the original four from Ao Oni, along with two new characters. Like the original, Nira Oni features random chases, puzzles, exploration through the floors of an abandoned hospital, a branching storyline and multiple endings.
Hiroshi and his five friends meet up at midnight for a night of urban exploration in an abandoned hospital on the outskirts of West Nira Point. The group consists of Hiroshi, Takeshi, Takuro and his girlfriend Mika, and Cassey and her little sister Ryan. Takeshi passes out from being too scared and while Hiroshi searches the kitchen for water, a big monster appears and scatters the group.
