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!

画风很舒服,剧情设定有趣,玩法生动有融合,是一款丰富的游戏,无聊时可以多玩玩
Love the Rhythm + Novel that they went for in this game. The artstyle and character design is cute and amazing. 10/10 Denpa. (Recommend to anyone starting this game to download a fan translation to get rid of the remaining garbage that has been left in the game from the english localization.)
