Mene is a shape-shifting succubus who survives by feeding on human emotions rather than lewd things. She runs a business where she turns into anyone you want: deceased loved ones, crushes, even fictional characters. Mene keeps a "food diary" full of her experiences with different clients and all the emotions she's eaten. One day she meets a boy named Asahi who's more interested in learning about Mene's true self than having her pretend to be someone. The problem is even Mene doesn't know what the "real her" is like.
