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.
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.
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!

genuinely an incredible game with charming characters, an interesting story, and extremely fun gameplay! being able to play a bunch of my favourite denpa songs in a rhythm game, and find new songs i didnt know before, is really cool and such a dream come true! 10/10 would recommend to anyone who loves rhythm games, denpa, or yuri :3 altho quick warning - stay far away from the fandom and the comments on any of the updates of the english translation. 10/10 game, with a 0/10 fandom. 99% of you need a reality check2 found this helpful
It's an ok rhythm game. I'll give it a recommendation despite them not fully reworking the english translation. There are unofficial english patches so I'm fine with it. The rhythm part of the game is very good. Decent mapping, decent play options with speed even though there's only 4 button modes. each song is guaranteed to have 4 difficulties. Decent enough song selection for it's price although the genre is pretty much the same style1 found this helpful
the story has some tear jerker moments but its not worth so skip gameplay and charts are fun art is very nice and the voice acting is great
i dont know how i got this many hours
Y E S ! ! !
MY HEART IS GUNNA EXPLODE FROM DOKI DOKI!!!
