Set in a alternative timeline where Lume Lights was not formed, a mysterious MIDIdoll (android doll) fell onto the surface of Sound World (or any world depend on the lore) after was she was supposed to be attending "Heaven" after being a living ex-punk rock human school girl from a car accident. The person responsible for "reviving" her is unknown, but being rich in thirst for a music experience, the lost MIDIdoll finds Jadiah who is about to enter work when she senses a "potential" in her skill. The cyborg mouse-cat Myumon stops her tracks to see her... Lost and in only a night gown, helps her getting herself settled at the Lume Lights shop.

Generic Heroine plays on the background and finds the right aesthetic for a MIDIdoll and a Cyborg!

The two formed Generic_Heroine.exe after testing out their mixing and transitioning skill son pre-exisitng songs.

The cat MIDIdoll Kise Sakusaku (or Kiseku for short) aims to become a top icon to get Gilili's attention, and Jadiah's dream is to become a top DJ to get Yokazenohorizon notice enough to earn interesting in a dream remix!

Later in time, Miu Yaeko joins the group, in exchange for her to become the "manager" of the unit, and partaking said band/unit to another world... (In D4DJ universe.)
