WHO YOU and publisher Alliance Arts have announced that Yunyun Syndrome!? Rhythm Psychosis will be released on PC via Steam on April 24, 2026, for $16.99.
This title focuses on a hikikomori youth, Qtie, who’s obsessed with Denpa music. This obsession causes her to suffer from brain rot and hallucinations, which take the form of a fake social media love story with her favorite imaginary online follower, Yunyun. However, a question that begins to form is whether this seemingly fictional follower is actually a resident of conventional reality.
Headphones are recommended for this rhythm adventure, where Qite’s love confessions for Yunyun take the form of love letter posts scattered online. Songs include “It’s a cherry kissing explosion” by Sakuranbo Kiss.
Alas, this process of continually pasting copypastas seems to have world-altering consequences, with the truth of Yunyun’s existence at its center. This setting boasts modern animation, exploring themes of depression and isolation, as well as the social anxieties resulting from online interactions. Over 30 songs and multiple endings will be achievable.
