Yunyun Syndrome!? Rhythm Psychosis Overview
Yunyun Syndrome!? Rhythm Psychosis is an upcoming rhythm adventure game releasing on PC via Steam on April 2026. The game focuses on Qtie, a hikikomori (socially withdrawn) girl whose obsession with "denpa songs" and a fictional character named "Yunyun" leads her to anonymously post online.
Players explore Qtie's delusional mind, with the main objective of corrupting the world with "Yunyun love" through her online posts, leading to potentially catastrophic global consequences. Gameplay combines rhythm-based segments with social media Browse. Players tap to the beat of over 30 denpa tracks and use successful rhythm performances to create "anonymous posts at peak moments," spreading "Yunyun-ification" to other social media users.
The game features multiple endings, reflecting the impact of Qtie's actions. Developed by WHO YOU and published by Alliance Arts, the game will support English, Japanese, Korean, Simplified Chinese, and Traditional Chinese.
