Tobian was a genius among mages, both in his own eyes and those of the people around him.
When he was a teenager, he grew to a meter and a half at the mere age of fifteen. Because of his strong body, his father considered him to be a good candidate for a warrior and wanted to send him to the Guild of Warriors to be trained strictly.
However, Tobian didn't go, being shrewish and making a scene and saying that he was going to be a Mage.
This was nonsense… What was the image of a Mage?
Not a strong but well-proportioned looking body, a refined manner, and eyes filled with intelligence.
Tobian was herculean, his thighs larger than the head of a child at his age—why be a damn Mage!
However, his father spoiled him, and when he saw how determined Tobian was to become a Mage, his father let him be a magic apprentice for a few years, assuming that he wouldn't make any progress and then come back crying and begging to become a Warrior.
