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