Sister Other Paranoia Wiki Overview
One page that points to every hub and key article on this unofficial fan wiki—including post-launch routes and endings.
What this wiki covers
This unofficial fan wiki tracks Sister Other Paranoia, the dark classic visual novel from HazeDenki (scenario and direction by nyalra) published by Serenity Forge on Steam (app 4240150). Planned release timing centers on August 14, 2026 (some press: August 15, 3:00 AM UTC), at about $9.99, with mature themes disclosed around blood, suggestive content, and mental health, plus a marketed mind-reading fantasy that can push others toward suicide.
We write for players who want accurate logistics, spoiler-light story context, systems explainers, and comfort tools—not rumor endings. Site languages: English (root paths) and Japanese (/ja/ prefixes). Steam also lists Simplified Chinese; this wiki does not.
