Kamijou Touya

Kamijou Touya is Touma's father. He is a businessman who travels a lot and collects various good luck charms due to Touma's unnatural streak of bad luck. He may seem silly at times but he does cares about his wife and son. He is partly responsible for causing Angel Fall, the spell that threw off a powerful angel in Heaven onto Earth without him knowing about it. Even though he is now happily married to her and has no interest with other women, he still manages to attract women, much to the chagrin of his wife and his own colleagues, who often complain that Touya's flaunting the fact he has a young wife (though the colleagues might just be jealous) yet still attracts women.

In the anime, he also gets a happy look on his face whenever he sees an attractive woman, much to his wife's irritation, though he still loves her dearly. In the light novels this is non-existent, compared to the highly exaggerated version in the anime.

Volume SS2 reveals that Touya's job is to prevent others buying shares of the company he belongs to for the purposes of hostile takeovers, a job that requires the person to have extensive economic and psychology knowledge to be able to succeed. In the same novel, he meets Lidvia Lorenzetti on one of his oversea trips, and after talking about the misfortune of his son and implying there's nothing anyone can do about it, Lidvia gives him a magical good luck charm that's undetectable by other magicians unless it is used actively for a spell, since she thrives on solving seemingly unsolvable problems. Unknown to the both of them, this good luck charm ends up being the catalyst to activate the spell 'Angel Fall'.
