When Sumire is summoned to another world by a powerful succubus, she must learn to master her new powers to return to her world.

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?

Sumire will have to pick up work around the town to save up the necessary 1 million gold she'll need to buy the precious potion and teleport back to her world! The only other option is to raise her succubus level by interacting with the locals and feeding off of their experiences, feelings, and dreams. The choice is yours to decide which path she'll take!
