Kagerou Shoukiin (青鬼院蜻蛉 Shōkiin Kagerō) is Karuta's master and also the former master of Soushi, and the friend of Banri Watanuki and Zange Natsume.
He died at age 24 and was reincarnated along with the others, and now lives in Maison de Ayakashi in Room #07.
When Kagerou is in human form, he wears a mask, and dresses in ancient European-like clothes. In Chapter 25 his reincarnated self without the mask looks exactly like Soushi but with black hair.
After the time skip, he is reincarnated to be 20 years old. He wears the same outfit. Also, in one chapter, his face is first seen without his mask on. It is revealed that his face looks very similar to Soushi's.
When he is in his youkai form, he wears a loose-fitting kimono, still wears his mask, and has horns and pointed horns such as Ririchiyo. His weapon is a cleave-like katana with bandages wrapped around the handle. He appears like a Shinigami (Soul Reaper).
Arrogant, eccentric and loud, Kagerou is a narcissist with a flair for drama. He can be quite a gentleman but you rarely see this side of him. He is shown to be quite sadistic, as he enjoys treating Karuta like a pet and refers to others as though they are inferior, such as calling them "human toilets" or "pigs". He believes that the world and everything in it exists in two flavors: sadism and masochism, and takes every opportunity to make this clear. Because of this, he is considered a great annoyance by the main cast. However, depsite his fairly odd and flamboyant mannerisms, Kagerou does have a level of intelligence, shown when he tests Soushi of his loyalty to Ririchiyo, eventually prompting the latter to reveal he was decieving her (but is proven to have quite messy handwriting).
Kagerou is Ririchiyo's fiancé, which Ririchiyo greatly opposes because it was decided by their parents. He used to exchange letters to her, but it was actually Soushi writing his letters for him. Kagerou's handwriting was equivalent of that of the standard kindergarten kid, which was considerably terrible.
Kagerou is Soushi's old master. However, Soushi claimed to have no self-respect as long as he served him, so Kagerou found Soushi boring. They later separated when they reached the age of twenty, along with Zange Nastume, when they all went to find jobs.
Karuta is Kagerou's Secret Service agent, but he treats her more like a slave than a person, such as dressing her in perverted clothes and putting a dog collar around her, though she doesn't mind as long as she has something to eat. He rarely sees her because he travels too much.
He was born into the wealthy Shoukiin family and had Miketsukami at his beck and call. His fiancée at the time was Ririchiyo and they communicated with each other through letters. Though he had no interest in it whatsoever, he wanted to keep Ririchiyo entertained, and ordered Miketsukami to continue writing back on his behalf.
When he was a child he played "games" with Miketsukami, Zange, and Watanuki. They poked fun of Watanuki's youkai form and based their games on him.
In Part 2, Kagerou is reincarnated as a 19-year-old. He is in the same class as Ririchiyo and Chino because he had to repeat high school, probably because he was always traveling. He is still friends with Miketsukami and Natsume, and they attended middle school together.
In Part 3, all of the residents got a letter from their reincarnated selves, saying what will happen in the future if they don't stop the attack. All characters are different ages from what they were before they died. Kagerou ended up dying.
- Although he is sadistic, he treats Karuta very well and would treat her to food.
- During the special, it was later found that if you press on the yellow gemstone, he would say "Human chamberpots" in a robotic voice. And if pressed on the second button of his vest, he will say "Livestock".
- He took a course through correspondence in order to improve his handwriting and was shown to pass.
