The Filial Hunter of Chick Class

At age four, orphan Gru awakened as the world’s youngest S-rank Hunter. But her system's first quest wasn't to slay monsters—it was to find a family. Now adopted by Korea’s strongest Hunter, she discovers a unique skill: she can register multiple guardians. The more she pleases them, the more ‘filial piety points’ she earns, unlocking immense power. Being a good daughter is the ultimate cheat code for leveling up. So she sets her sights on an audacious new goal: to collect every S-rank Hunter in the world and make them her family.
