Leonardo

He is a member of the Hero Faction and a young boy who possesses the High-grade God-Slaying Tool "Annihilation Maker." Though still in the process of growth, his unique talent lies in his ability to create "Anti-Monsters" tailored to counter the abilities of his opponents. He devoted himself to gathering data on bizarre entities and conducting research to produce the most optimal Anti-Monsters.

However, after the "Beast Riot," he was forcefully turned into a Broken Gear user, resulting in him becoming incapacitated. Daishakuten then stole his "Beast Creation" ability and banished him to the Underworld. By a twist of fate, he later came to be under the care of the "Watcher of the Child of God." His story is reminiscent of an epic poem depicting the intersection of power, responsibility, and fate, raising high expectations for future developments. Watching his growth and comeback is one of the greatest joys for fans.
