Wise Man's Grandchild

In the kingdom of Earlshide, famed hero Merlin Wolford chooses a quiet retirement in the countryside, where he devotes himself to raising an orphan he once rescued. That child, Shin, carries memories of a previous life as an ordinary Japanese salaryman, reborn into a world of magic. Under Merlin’s care, Shin grows into a prodigy with astonishing talent in spellcraft and martial arts—enough to surprise even his legendary guardian.

When Shin turns fifteen, a serious gap in his upbringing becomes hard to ignore: he’s been trained for battle, but not for everyday life. Socially awkward and lacking basic common sense, he’s sent to the kingdom’s Magic Academy to develop alongside others his age. Yet any hope of blending in disappears quickly as his abilities make him a celebrity in the capital, pulling him into new friendships, a changing world, and the looming threats gathering around the city.
