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 extensive knowledge of the economy and human psychology. 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'. In Volume SS2 he will also befriend Misaka Tabikake in a bar and unwillingly helped the Gemstone Girl to escape from her pursuers.

Quotes
(During SS2) “''Talking to a prostitute in a rundown bar in a stylish city like London seems pretty dangerous to me. Not even the protagonist of a manga that’s always getting in trouble would do something as dangerous as this. It’s like stepping out on a suspension bridge when the ropes are about to snap.''”

Trivia

 * When Misaka Mikoto saw Touya's antics she noted that his silly behavior to girls was just as bad as Touma's.
