A brief description of the manga The Weakest Tamer Began a Journey to Pick up Trash:
When Ivy was born, she remembered her past life. She tries to avoid fighting over her memories. But fate was cruel – when children tried to learn about themselves and their aptitudes, Ivy had only one talent – Taming.
Ivy was weak from birth and could tame only a slug, no more. Parents hated her because of this (apparently, to be weak is a crime?). Only one woman in her native village treated her as her daughter.
But after her “death” Ivy got an unambiguous hint and ran away from home.
She met a slug whom she called Sora. And this is how our story begins – with a little girl, who is destined to become the Tamer.
