Which digital format of Yunyun Syndrome!? Rhythm Psychosis should I buy for PC? An Account or a Steam Key ?

The account format is cheaper but has a more complicated activation process compared to a simple key or code. It may also cause access issues in the future, which is why we only recommend it to users who are familiar with this format or have used it before. If you’re looking for a simpler and safer activation process and don’t mind paying a bit more, we recommend buying the Steam Key format.

Yes, stores that sell this format usually guide users through the entire activation process, and if any issues arise, they offer customer support services. And if they don’t help, don’t worry—we’re here to assist you too.

The Steam Key format is what we always recommend due to its ease of use and higher security compared to any other format. You just need to redeem the key in your account to download Yunyun Syndrome!?

The store does not send my order and does not respond to support. What can I do?

About Yunyun Syndrome!? Rhythm Psychosis

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.

⚡About DenpaSongs!

Q. What is a “denpa” song?
It is a genre of music that is intentionally strange and catchy. All playable songs in this game are denpa songs.
Many popular denpa songs such as “it’s a cherry kissing explosion” (Sakuranbo Kiss) and many more are featured!
