A famous and capable incubus among his kind. He is the older brother of Sakyun, a succubus. For some reason, he seems to dislike the idea of Sakyun, who isn't acting much like a succubus, becoming more 'demon-like' as her popularity grows.

He is said to look very similar to the father of the princess, Aurora Suya Rhys Kaymin, who is a hostage in the Demon Castle. His hair is a dark reddish-purple at the roots, fading into a lighter shade towards the tips.

Before working at the Demon Castle, he spent his time dealing with many women until he was suddenly scouted one day... He knows that being a bit loose and casual makes humans feel more comfortable.

His birthday is December 6th. He likes water jelly and milk rice cakes, and his hobby is disguise. He enjoys taking care of small children. Among seafood, he prefers oysters because they can be slurped down easily.

He can peer into the dreams of others. He is so lazy that he's second to none when it comes to avoiding work. When he returned to the Demon Castle after a long time, he would work while lying on the floor, and sometimes end up falling asleep right there...

He has critiqued the Devi-Devils alongside the Demon King and Hades, who stays in the Old Demon Castle. He always maintains a relaxed demeanor. Although he has a high tolerance for alcohol, he seems to drink it more for convenience while working rather than for the taste.

His family home is in 'Landheart Village' within the 'Incubus Village.' Landheart Village is surprisingly peaceful rather than lewd (at least when you first enter). Inkyun said he worked relatively hard when he went back home because he 'wanted to show his best side in his hometown.'

In the Incubus Village, it is said that when most races fall asleep, the Devi-Devils, succubi, and incubi living there enter the dreams of men and women to tempt, torment, and drain their magical power at will. Of course, it's said to be fine if you use a protective mosquito net(?).

Incidentally, the reason incubi and succubi don't go naked when entering dreams is that they think attacking without clothes is very tacky.

His mother back home is also a force to be reckoned with. Inkyun's mother appears to have a soft, generous, and kind personality on the surface, but as an incubus, she fights using her own natural charm without transforming into others, a trait Inkyun inherited. Regarding Inkyun, she once said, 'With that plump body (he's not actually plump, but she calls him that), I want to make him a charming little piglet and hear him oink...'

Inkyun's father used to walk the path of an asura seeking ultimate beauty as an incubus, but after being shocked by his wife's tactics, he sought her teachings and learned about love. He usually covers his face to prevent commotions caused by his excessive beauty...
