Zange Natsume is just like the others, Natsume is a half youkai (demon) and half human. He is the pair of Banri. He has a cheerful personality and usually wears bunny ears. He is particularly fond of Soushi and tenderly calls him "Sou-tan".
Natsume died of illness at age 24 after Sōshi was killed in the enemy youkai's raid. He was reincarnated, and is currently 21.
AppearanceEditZange has red hair. Under his bandage on his forehead, he has a third eye which he uncovers in his youkai form. He is usually seen wearing a black suit and black gloves in his human form. In his youkai form, he also uncovers two more eyes, one in his palm and the other in his wrist. He also wears bunny ears in both human form and youkai.
Most of the time, he has a very cheerful personality. Though he seems to hide his emotions at times where he sees visions abruptly, authentically Zange is very silly and comical person. He tries not to let any of his true feelings to be exposed to other people, trying to let it overcome with a humor when he does happen to let show his emotions involutarily. Because he can see everything with his eye, he sometimes threatens other people (humorously) with their private issues to get what he wants. He is able to attract other people with his sense of humor.
Kagerou is Zange's childhood friend. They always hung out together with Soushi and Banri until they all reached the age of 20 and they went to find jobs. Though, they all ended up together at Ayakashi Kan with Soushi and Zange working as Secret Service agents and Kagerou and Banri as normal residents.
Soushi is also one of Zange's childhood friends. Zange calls him "Sou-tan~" and he tells him that he missed him even when they just haven't seen each other for only an hour. In episode 4 when he bumps in behind Soushi you see roses in the background implying that Zange is somewhat infatuated when he's around Soushi while blushing.
He is Banri's Secret Service agent in Part 1 of the storyline. They are also childhood friends but Banri states that all he and Kagerou did was bully him. Zange and Kagerou calls him "Rascal" because of his youkai form. In Part 3 of the storyline, it is hinted that in their past lives, Banri promised, and became a doctor hoping to heal Zange's condition but failed. Zange's motivation in being Banri's SS Agent was to protect and encourage Banri to not (again) waste fruitless energy in him.
Zange was born in St. Mary's Hospital, weighing 6.6 lbs. He was raised well, a B-type, Virgo, and is single. He mentioned that he was burdened in life by the fact that he is a Hyakume (100 eyes).
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 current the same ages as before.
