Seere von Devata was the only blood relative of the former Demon King and previously held the 2nd rank in the Demon Realm.Following a sudden, devastating war and the defeat of the previous Demon King, Seere was expected to take the throne but was considered too young. Consequently, the young Seere ascended to the throne as the Demon King at just five years old. This leads to the core plot of the story: the protagonist is suddenly summoned or takes over as a 5-year-old Demon King in a simulation-like setting, tasked with ruling the kingdom, navigating political dangers, and raising Seere. Seere's royal bloodline and position in the Demon Realm make him a central character to the overarching politics of the monster realm and the protagonist's survival.
