Lv999 no Murabito

In Earthclear, everyone is born into a fixed role, and villagers are the weakest of all. Most never rise above Level 5—except Kouji Kagami, who is Level…999?! On a monster hunt, he meets Alice, the Demon King’s daughter, and discovers they share an impossible dream: coexistence between humans and demons. In a world destined for conflict, they charge into battle to defy fate and shatter the rules.
