Kamigami Ni Sodaterare Shimo No, Saikyou To Naru

The gods living in the mountain picked up an abandoned child and name him Will. They poured all their love into raising him, however, when it came to deciding on what he should become, they all had their own vision in mind.
"This child is talented with the sword. Let's make him into a peerless swordsman."
"No, this child is kind. Let's make him the strongest healer."
"No, this child is a genius. Let's make him into the ultimate magician."
To placate them, the chief god comes up with a proposal. "How about he trains in all of them?"
Through the curriculum given to him by the God of the Sword, Goddess of Healing, and the God of Sorcery, Will becomes the strongest and sets out on his journey at 14.
