Kankuro has blue eyes and azure hair. He appears to be wearing an all black military uniform. Besides being an onmyouji, he is also a doctor to many other onmyouji residing in the island. His mask is an "admonition" as stated by Ujii Kengo. Underneath his mask, the seal of the Impurity Eater is shown on his mouth in the form of stitches and is eventually removed during his battle with Rokuro. When using the Impurity Eater, his teeth temporarily become sharp (though, not as sharp as Rokuro's).
Kankuro and Kengo Ujii are childhood friends. Kankuro is a calm and easygoing person but gets mad if he's being underestimated.
Kankuro is considered to be one of the most kindest members of the Twelve Guardians, a notable example of his kindness is during his time with the sick children of the Sahanasaki Class with Kengo noting that the children were happy to having been touched by his warmth. He is very caring towards the Sahanasaki Class, to the point of being too focused on teaching and spending time with them rather than his own training, as mentioned by one of the nurses. However, after their deaths by his own hand, he became emotionally scarred for years, which results in him sealing the Impurity Eater and never used it again until his battle with Rokuro.
Kankuro greatly despised the Impurity Eater, the same technique he used to kill the impurity along with the children it took as hostages, because to him, it is nothing but a curse which symbolizes his abominable memory and the weakness inside him. This also means that he hates himself, to the point where Kengo stated he is fighting in a way to suggest he doesn't care if he dies. However, thanks to Rokuro and Kengo, he is finally able to move on from his past and accept the power he once despised.
It is often shown that he likes to tease Kengo by calling him "Ken-chan" (which is his nickname during childhood). He often uses Kengo as his test subject for his experiments (possibly dissecting since he uses a scalpel), he once tricked him into accepting his offer of aid to quickly cure his illness, which results in Kengo comically becoming traumatized and afraid of Kankuro as a doctor.
In the anime, he shows interest in dissecting impurities.
In the past, Kankuro was a doctor that treated sick children with exorcist related problems and taught them exorcism. One day, he took them outside of the hospital and to where Kengo was working as security for the island.
However, an impurity was able to break through without being detected and took the children as hostages, making Kankuro choose whether to protect the island or children. To the plea of an injured Kengo, he chose the island and used Impurity Eater to kill the impurity, along with the children, thus saving the island.
Ever since then, he covered his mouth with a mask to seal Impurity Eater.
