Things are tense on the island of Cenancle, where a powerful machine called Buer has been wreaking havoc underground. All that stands in its way are two cyborg girls: Nanakorobi Nene, who has a human brain inside her artificial body, and Clarion, the combat cyborg who belongs to inventor Uzal Delilah...at least for now. Nene is determined to protect her new friends, especially Clarion, but she has family on Cenancle too. Nene’s never met her eccentric aunt Takumi, but Takumi is opening her home to Nene and providing her with some unexpected quirks and challenges to deal with!
