Ivy's daily life is anything but the peaceful, ordinary childhood enjoyed by other children. She possesses memories of a past life in another world, and at five years old, she learns to her parents' shame that she only has one low-level skill: taming extremely weak creatures. Unwanted by her family, she begins living in a nearby forest, learning to survive on her own with the help of her village's local fortune-teller. But when Ivy's "starless" existence is blamed for the old woman's misfortune a few years later, the child is forced to flee to avoid being killed. She journies from town to town collecting discarded items and selling what she can, until one day Ivy encounters a rare slime that she names Sora. What adventures await the young girl and her slimy new companion?
