Following an unforeseen accident in his past life, Maki is reborn into a new world as Leon. Unlike other reincarnated heroes, Leon awakens as a newborn infant, retaining the consciousness and some memories from his previous existence. He soon realizes he has been born into a powerful family—his father, Gustav, is the legendary fighter known as Berserker Gustav, and his mother, Stella, is a renowned mage; both were members of the previous hero's party.
As Leon grapples with adapting to his new life as a toddler, he uncovers an extraordinary ability: the power to use magic. This discovery changes everything. He begins practicing in secret, trying to control his newfound abilities in a body too young and weak to handle such power.
