Sister Other Paranoia Overview
Sister Other: Paranoia is a psychological visual novel from HazeDenki and Serenity Forge. The story starts with a reclusive light-novel author who suddenly gains the ability to read minds. He receives his telepathy after repeatedly being overwhelmed by the "ugliness of society" and harboring fear towards people.
As his newfound power exposes the jealousy, resentment, and hidden emotions of those around him, he becomes increasingly isolated, paranoid, and distrustful of others. His only beacon of comfort is his younger sister, while he confronts his growing loneliness and hatred for everyone else.
