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!

¿Quién es Yunyun? Para los perdidos, ella es la visión. Para los hambrientos, ella es la chef. Para los sedientos, ella es el agua. Si Yunyun piensa, yo estoy de acuerdo. Si Yunyun ENVÍA, yo RECIBO. Si Yunyun tiene un millon de fans, yo soy uno de ellos. Si Yunyun tiene diez fans, yo soy uno de ellos. Si Yunyun tiene un solo fan, ese soy yo. Si Yunyun no tiene fans, ya no existo en este mundo. Si todo el mundo está en contra de Yunyun, yo estoy en contra de todo el mundo. Hasta recibir el ultimo bit de Denpa, yo amaré a Yunyun
MY HEART IS GUNNA EXPLODE FROM DOKI DOKI!!!

융융! 참 귀여운 융융과 말랑한 Q짱입니다 씹덕이기만 하면 리듬게임을 즐기지 않아도 충분히 해봄직 합니다 물론 좀많이씹덕이어야만함 근데 확실히 전파계 게임이기 때문에 관련 게임을 해본 적이 없거나 관련 문화에 대해 잘 모른다고 하면 재미가 많이 떨어질 겁니다 해당되시는 분들은 고민을 좀 해봐야할듯함 트레일러보고 재밌어보임 < 이러면 무조건 사도 후회안할듯
세상에게 사랑받지 못한 Q짱이 사랑스럽고 4키 리듬게임도 나쁘지 않았네요. 특히 KOTOKO님의 노래들을 이 시대에 리듬게임으로 접한다는 감각 자체가 감동이었습니다. 노래가 많진 않아서 DLC를 사야하고 스토리도 찝찝합니다만 한순간이나마 어렸을때 추억을 떠올릴 수 있어 좋았습니다.
