Irizu

Irizu is the main antagonist of the "found footage" horror game, "Sara is Missing" - it is unique in being an antagonist one does not fully see but rather interacts with via texts, videos and images : since the premise of the game is that you stumble across the mobile phone of the titular Sara.

Irizu is a mysterious, pseudo-philosophical figure who is revealed to be part of a Satanic cult as well as the internet legend known as the "red room" (based on dark web snuff-sites) - Irizu thus justifies acts of torture and murder as being part of the way things should be and engages the player in varied mind-games while trying to recruit them into their cult.
