Everyone else should die, except my sister
Boulder, Colo. (June 16, 2026) – Today, publisher Serenity Forge (Fractured Blooms, Slay the Princess, To The Moon, Doki Doki Literature Club!) and developer Studio HazeDenki, the team behind NEEDY GIRL OVERDOSE, announced Sister Other Paranoia, a surreal interactive animation presented as a dark visual novel, accompanied by a new trailer:
Sister Other Paranoia follows a quiet first-year university student with a strange knack for sensing the “colors” of other people’s emotions. To escape his rough-tempered parents and the noise of everyday life, he shuts himself away in his room with his gentle, highly gifted younger sister, spending his days reading books and writing his own light novel, the wave of envy and malice that begin to surround him -both online and offline- push his mind to the brink, and he starts to feel a very real, murderous urge toward the people around him.
Sister Other Paranoia blends a retro horror “denpa” atmosphere with a focus on psychological tension. Players make key dialogue choices about how the protagonist responds to the unpleasant people around him, and watch as those choices steadily twist the relationships and push each character toward a different, often disturbing fate.
To celebrate the announcement, Serenity Forge will be heading to Anime Expo on July 2-5 with Nyalra, the main creator of Sister Other Paranoia and NEEDY GIRL OVERDOSE, VO and the creators of the anime NEEDY GIRL OVERDOSE, which is currently available on Crunchyroll. The event will feature a panel and an autograph session with Nyalra, where new merchandise for both games will be available for Anime Expo attendees.
