Kyou is a relatively conscientious person who is kind. He is also a devoted husband to his wife Aconita. However, when it comes to angels, he acts quite perverted and also enjoys collecting their hearts. He loves angels in many ways and has a dizzyingly large collection of angel hearts stored in his home. He’s been described to be a great guy who happens to have some wild kinks. Satanick once drew a doujinshi for him showing Tsurugigozen's heart being violated by Fumus.
