About this game
High and vibin’ with denpa songs, we’ll corrupt the entire Internet! Hehe. all we need is a bit of otaku love, that’s all.
This is a rhythm-adventure game where you play as a hikikomori (shut-in) girl who’s high on denpa songs. Become Yunyun-brained and lose all self-control to anonymously post on social media and destroy the world with your Yunyun brain rot.
Have a Doki-Doki experience with over 30 denpa songs and multiple endings.
Q. Why did she become a hikikomori?
Q. How does anonymous online posting lead to world destruction?
Q. Does a happy ending exist for a degenerate otaku?
The answers to those “Q” s lie at the convergence of insanity and denpa psychosis.
Now, put those headphones on and become ill with Yunyun Syndrome!? Rhythm Psychosis.
⚡ Anonymously Post Online and Infect the Whole World with Yunyun-brain!
Get high on denpa songs and spread your heartful psychosis to everyone else!
⚡Characters!
・Qtie (CV:Nanahira)
The main character. A hikikomori. She suffered too much irl that she’s become a little (very) fuzzy in the head. Her obsessive love for the fictional character “Yunyun” is for sure an illness. Her overly “high” state from overdosing denpa songs causes her to propagate Yunyun love. Will there really be a happy end for such a degenerate otaku?
・Yunyun (CV:Haruko Momoi)
A fictional character that loves Qtie. A very much angelic devil. She will speak to Qtie through the monitor screen. Whilst the truth is unknown, most likely, she is just a figment of Qtie's imagination. It’s joever for her.
