Publisher Serenity Forge (Fractured Blooms, Slay the Princess, Doki Doki Literature Club Plus!) and developer HazeDenki, released Sister Other Paranoia, a dark psychological visual novel, available now on Steam for $9.99, accompanied by a new trailer:

Sister Other Paranoia follows a literature-major university student born with a synesthesia-like sensitivity that lets him perceive other people’s emotions as colors. When a light novel he writes unexpectedly wins an award, the recognition sharpens his gift until he begins to fully read the minds around him. What he finds there is envy, malice, and a jealousy that hurts his fragile heart. Withdrawing ever further from the world, he clings to the one comfort left to him: his gentle, gifted younger sister.

Rather than presenting a straightforward narrative, Sister Other Paranoia places players within the protagonist’s distorted view of the world, where every interaction is shaped by his warped understanding of others and his deepening paranoia. The choices the player makes steer those relationships toward different, often disturbing fates, while the game refuses any easy line between right and wrong. Rendered in a retro “denpa” horror style with text that floods the screen, it leaves players with questions about guilt, judgment, and what happiness really means.

Sister Other Paranoia is directed and written by acclaimed creator Nyalra, alongside Ohisashiburi, Aiobahn +81, and Maruino, and marks the first release from Studio HazeDenki.
