Titles/Names Edit


Atain name: Blowslain (meaning: Bewitching Blood)

Lord Perdien (Perdien means "no name")


He was born with Amber/orange eyes and black hair. He dyes his hair to match Miryu. He keeps the Orange hair until the end of chapter 17

He reverts back to his Black hair afterwards. When in his incubus form he has up to three pairs of wings (his mother resides in the third set) and a set of black, red, and gold costume. 

 He is known to have a beautiful face.


Son-complex. He always places his son need above all. While most of the time he appears to have a childish nature he also has manipulative personality. He takes pride at being a father, and is always over-protective of Miryu. He is ready to sacrifice everything as long as his son is safe. He doesn't hesitate to hurt or even kill anyone that dares to hurt his son, and will often threaten those he deems to be dangerous. Jin also listens to what his son says, and often if not always does anything to make Miryu happy. He will often stalk his son whenever he goes. He has Gynophobia (abnormal fear of women), that he got from a childhood experience with his adopted sister (who he marries later on). Beside Miryu, Jin also cares about his father, as shown on several occasions in story, and doesn't have a good relationship with his mother. He also has a beautiful singing voice that he has inherited from his father.

Synopsis Edit


Jin's Mother is the Demon Queen and his Father is an Atain (rare beings with magical blood and possess the power to immortality). His mother found the Atain and had a child with him to strengthen her “Blood Tie.”

Jin’s wife was his adoptive sister who is an Atain and hated demons.

The role of the Blood Tie is to give power to the demon queen/king to control the possessors of the “Blood Tie.” The Blood Tie holders are her descendants. Here, the half Atain-Demon Jin and the three-forth Atain one-forth Demon Miryu (Jin’s son) give power to the Demon Queen.

Jin also has an Arch-disciple Lan (an angel who’s mission is to kill one particular demon), who has been following Jin all his life trying to kill him, but grows an affection towards Miryu, and has learned to live with Jin.

Jin’s father committed suicide in front of him.
