One day, while examining a book in the library, Sumire finds herself summoned to another world! Brought there by the powerful succubus Melissa, Sumire herself has been transformed into a succubus. As a being that thrives and amplifies power by immersing in human emotions, dreams, and experiences, she has two options to secure a way back to her world: either save up a million gold for a mystical potion or level up her succubus powers through enriching interactions with inhabitants of this new world. Will she ever manage to overcome the challenges and return home?
