About Sister Other Paranoia

Sister Other Paranoia is a classic visual novel about an isolated young man who can read minds and his relationship with his younger sister. Unable to bear the cruelty of the world and afraid of other people, he shuts himself away and submits a light novel he has written. It unexpectedly wins a newcomer’s award, but the jealousy and envy that follow deepen his distrust of the few relationships he still has. People around him hurt his fragile heart without realizing it, leaving his sister, who lives with him, as his only comfort. The two cling to each other in a twisted, unhealthy codependency.

Read and make choices

The text fills the screen as you read and click through the story; you can also right-click to hide it and view the artwork. You follow the gloomy real world through the protagonist’s sensitive perspective, then return home to the time he spends with his sister.

As tensions with people around him build, you can use his mind-reading ability to exploit their deep-seated insecurities and drive them to suicide. The story asks whether this is justified, what happiness means, and what future awaits the protagonist and his sister.
