TOKYO — April 13, 2025 — Yunyun Syndrome!? Rhythm Psychosis, the psychological rhythm adventure from publisher Alliance Arts and developer WHO YOU, battles brainrot on PC via Steam on Monday, October 20, 2025, as announced during INDIE Live Expo.
The pressures of daily life have turned protagonist Qtie into a recluse with a preference for parasocial interactions over anything face-to-face. Dissociate from reality to the tune of dangerously catchy, mind-altering denpa music, and navigate the hallucination-induced horrors of a long-distance love story with Yunyun — a person who may or may not exist.
Tap buttons on beat to proclaim Qtie’s love from the digital rooftops, spreading Yunyun Syndrome to all of Qtie’s followers. Type out love notes, sweet nothings (<3), and daily reminders of her affection to boost her social following... and pester those toxic Yunyun haters with her unashamed adoration. They’re the toxic ones, not you!
Overdose on more than 30 hypnotic denpa songs, including artist KOTOKO’s "sakuranbokissu~bakuhatsudamo~n~," “Nee,…shiyou yo!,” “Mighty Heart ~Aru Hi no Kenka, Itsumo no Koigokoro~”, and many more.
Will Qtie’s anonymous online posting efforts prove valiant, resulting in a dream romance? Or will unrequited affections lead down a sinister, revenge-fueled path? All is fair in love and war — buckle up for a branching rhythmic narrative adventure where happily ever after, the destruction of the internet, and humanity's annihilation are all a mere mouse-click away.
Yunyun Syndrome!? Rhythm Psychosis will arrive on PC via Steam in 2024 with support for English, Japanese, Korean, Simplified Chinese, and Traditional Chinese language options.
