About the game
Yunyun Syndrome!? Rhythm Psychosis follows a withdrawn young woman whose life revolves around anonymous online posting, as her fixation on denpa-style music gradually turns the world around her upside down. The rhythm adventure was built by Alliance Arts together with WHO YOU, with Alliance Arts also serving as publisher, and the title launched in 2026. Musical challenges chart her descent deeper into internet culture and compulsive posting.
