[@VitaVitaAR] I wrote in his abilities that he can learn magic, but he is not talented for it. His master thought it would be too much of a hassle with little return to teach him magecraft so he didn't bother. He wanted a fighter, not a magus.

Maybe it will give you an idea of his magic potential if I say he was originally a Matou in a FSN RP on another forum. I changed his bio to fit the current setting.
