Byeongariban Hunter-neun Hyodo Jung!

In a world where special powers awaken in individuals, a 4-year-old child becomes an S-class hunter but has no parents. Assigned a quest to find guardians, she is eventually adopted by the nation’s top hunter. With a new skill that allows her to register caregivers and earn "filial piety points" for growth, she sets out to gather the best guardians to grow stronger and thrive.
