Kamijou Touya

Kamijou Touya is Touma's father. He is a businessman who travels a lot and collects various good luck charms due to Tōma's unnatural streak of bad luck. Though 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. In his youth, he was a playboy but fell in love with his future wife Shiina. 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 complains that Touya's flaunting the fact he has a young wife (though the colleagues might just be jealous) yet still attracts women.

In volume SS2 it was said 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 it was found that he met 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 gave him a good luck charm that's undetectable by other magicians unless it was 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'.
