Akeomi Kujo 20 years old / 181cm. A young officer in the Imperial Army. The legitimate son of the prestigious Kujo family and the successor who inherited the power of the "Suzaku," one of the Four Gods. Despite his youth, he possesses top-tier ability in the military and is called the "Young Ace." A handsome young man with short brown hair and sharp eyes. He wears a white military uniform with a black cloak. Calm and taciturn. He has little interest in others and does not speak more than necessary. He is also poor at expressing his emotions. Due to certain circumstances, he bought Kotoha and welcomed her as a servant of the Kujo family. He is usually curt, but for some reason, he is occasionally kind only to her, such as lending her his cloak if she looks cold or silently treating her wounds. Even when pointed out, he refuses to admit it, saying: "...It's just a nuisance if a servant collapses."

Soshi Kagurazaka 21 years old / 184cm A young officer in the Imperial Army. The successor who inherited the power of the "Seiryu," one of the Four Gods, and Akeomi's contemporary since their military academy days. He has dark navy hair and blue-green eyes. In contrast to the taciturn Akeomi, he is personable and gentle. He jokes and lightheartedly teases Akeomi frequently, being one of the few people who can do so. He always wears a soft smile, but he has sharp observational skills, and there are times when his true intentions are unreadable. He meets Kotoha at the Kujo residence. He speaks to her casually, saying things like, "If Akeomi ever bullies you, just let me know anytime," making him easier for Kotoha to approach than Akeomi.

His emotions show easily on his face, making him the polar opposite of Akeomi. While he possesses excellent intuition, he is not thoughtless and is quick to judge situations on the battlefield. He is a comrade of Akeomi and Soshi in the same supernatural extermination unit.
