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.
Get high on denpa songs and spread your heartful psychosis to everyone else!
・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.
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!

新手友善 主題稍有深度 喜歡遊玩中很多很搞怪的腦洞
крутая игра мне понравлось игровая импотенция была вылечена на 10 часов
If you lived through the old 2000s otaku internet, playing Stepmania and FFR whilst partaking in IOSYS and 2ch flash animations (or any combination of those), you need to get this. I find Yunyun Syndrome to be an incredibly perfect fit, in that it's a rhythm game in the spirit of the bygone days. Does your local arcade's DDR Extreme cab have a blown arrow? Did someone matrix walk on the screen one too many times? Are you are in the majority that can't play IIDX because you aren't near Sunnyvale Golfland or Arcade Infinity? Then just play O2Jam or Dancing Onigiri. FFR has Party 4U on it. It's allright. Such are the memories conjured up when I play this. The song list encapsulates all the ages of memes and otakudom from then to now. And it's a well thought-out game. You can change many of the parameters (which is good because I found the default timing to be really early), and if you pause during the song, it gives you a countdown beforehand. It's these small details that show that Yunyun Syndrome has been given a lot of attention and design while being made. There's a wide range of difficulties, but the spread and Insane BMS players will only get the high challenge from playing the "Degenerate" level. In that vein it's also good that you get the feel that there's more to do than just bash the keyboard. The whole design of Qtie's story and how you gain clout while playing the songs interwoven together really unifies the past of obsessing over an anime character towards the nowadays of social media fake news and Hit Like And Subscribe. And if you are submitting to AJATT, there is a lot of Japanese text to mine N+1 sentence cards out of, and dialogue to listen to (Nanahira is one of the VAs!). That being said, the Gen Z English translation is a riot. The TL;DR is You Should Get This.
