In a world where awakened individuals with special abilities are created by the system, a unique story begins in Saebom Kindergarten's Chick Class. At just 4 years old, Gru awakens as an S-class hunter. Along with this extraordinary awakening comes a special quest: [Quest: A child needs a strong guardian!] Why is a guardian necessary? Because Gru has no parents—neither a mother nor a father. After a series of twists and turns, Gru, who is without a family, is adopted by Korea's top hunter. Along the way, Gru's abilities continue to evolve, and new skills emerge. [Let's find a new caregiver and register for the slot!] [Children earn 'filial piety points' through various activities, which can be used in many ways.] It turns out rapid growth is possible by gathering caregivers! "That's incredible! I'll recruit all the S-class fosters!" (Source: D&C Media, translated)
