Demonophobia

Demonophobia is a Guro survival horror game made in 2008 by an anonymous creator named 237. It follows Kunikai Sakuri as she finds herself in Hell following the foolish use of an occult tome in a bid to take revenge upon her bullies from school, and focuses on her efforts to escape from Hell and the often horrific suffering that she goes through in the process. Along the way, she meets the only friendly demon in the game, Ritz (Demonophobia), who acts as her guide.
