Synopsis: Kenja no Mago

Destined to meet his demise in a devastating mishap, a young boy was reborn into an entirely different realm. Dubbed as "Sage," Merlin Wolford, the nationalistic defender, chanced upon the child and bestowed upon him the moniker "Shin." As a cherished grandson, Shin was nurtured and educated under Merlin's close guidance and attained impressive abilities. However, upon reaching fifteen, Merlin realized that he had neglected to instruct him in one crucial aspect - practicality. Thus commenced Shin's peculiar expedition as a singular and remarkable youth.
