The first creature of the abyss that we come across is Hild, the Demon Leader of Hell, yes, that Hell. Who wouldn’t want a happy-go-lucky, all powerful demon as a mother? As long as you don’t sneak out late at night, you have nothing to fear from her. Let’s hope that Urd didn’t do that too much while she was a teenager. But, who knows, Hild might have made a younger version of herself to go out with Urd on those wild nights. Not a bad mother when you come to think of it. But, I must again warn you not to make her mad, she is powerful enough to level a city the size of Tokyo if she breaks her bonds and goes wild.

Occult research is an odd club to have in a school and the president at the Kouh Academy’s Occult Research Club is the next demon on this list. Yes, I am talking about Rias Gremory, a pure-blooded devil and the sister of Lucifer himself… well, maybe not that Lucifer, but still a devil in his own right. Rias, better known as the Princess of Destruction, is among the many women who fall in love with Issei Hyoudou, the Harem King himself. Rias was the reason that Issei became a Devil after his first girlfriend cast judgment on him and slew him with her holy powers. Being a powerful devil is good and all, but Rias has a horde of followers…. slaves, which she can command on a moment’s notice. She even brings a league of smaller devils to back her up if she needs it.

We all have that friend who is always starting fights. It doesn’t matter if it’s with one of his friends or a complete stranger, he always wants to fight. But when it comes to someone else who wants to pick a fight with you or another one of your friends, that brawler friend is always there for you to knock the other guy on his rump. This brings us to Natsu Dragneel, the next demon on the list. The human Natsu Dragneel died over 400 years ago. His story would have ended there, if it wasn’t for the most evil mage of all time, Zeref Dragneel, Natsu’s brother, who brought his beloved sibling back from the abyss to join the ranks of the demon race, Etherious.

Sometimes, you need a demon to fight a demon, this is something that the Organization knows all too well as it has made over 150 generations of these half demon Silver-Eyed Witches to fight full demons, known as Yoma. Claire, unlike most of the Claymores, choses to take the flesh and blood from a fellow Claymore instead of a Yoma when she became a Claymore, becoming the first Silver-Eyed Witch to be only one fourth Yoma, which lead everyone to think she was a failure. After being critically wounded in a fight, Claire went beyond the limits set on all Claymores and turned into an Awakened Being, a demon more powerful than any Yoma. After she defeated her foe, she was able to regain her control, becoming the first partially Awakened Being.

When you think of a demon, a snot-nosed brat is probably the furthest thing from your mind when you are picturing it. Well, in her child-form, Nelliel is just that, an almost powerless child Arrancar who is even weaker than most normal Hallows, the demons that inhabit the land of Hueco Mundo. However, the grown-up version of Nel is a force to be reckoned with. When Nel transforms into her grown-up self, she becomes the third-strongest Espada, and has a decent set of… cushions, that is typical in Japanese anime. When Ichigo and his team finish in Hueco Mundo, they leave her behind and we don’t see any more from her in the anime world. Back in the manga, she continues to be her child shelf for almost two years until she comes to Ichigo for help. After which, we get to see the grown-up version once again, ruling Hueco Mundo as they come to help Ichigo fight the final fight.

Just because you’re over 2000 years old, doesn’t mean you’re good with money. Dante, the son of the human Eva and the demon Sparda, has a thriving business, where he deals with the supernatural so us normal humans don’t have too much to worry about. Dante carries around a guitar case, but he doesn’t keep a guitar in it. Unlike other demons, he uses a sword and pistol to finish off his foes. Don’t steal his sweets, or you just might become one of those foes that will be served a bullet from the black and white pistols.

High school life is tough for everyone. It must be all those hormonal imbalances and discoveries that happen in a teenager’s life. Hair growing in strange new places, your voice changing, blue flaming horns appearing on your head and gaining interest in… wait, horns… that’s not right, well, not for most normal high school students. However, Rin Okumura is no ordinary student as he is a demon who was sent to Earth as a child since his father, Satan, couldn’t find a suitable human to wear. So, he sent his son to become that vessel when the time comes. Now, if only Rin wasn’t able to take care of himself, we might have trouble to look forward to.

“Lord, what fools these mortals be!” Ryuk must have been watching over the shoulder of Shakespeare when Puck spoke those words on the stage of a Midsummers Night’s Dream and took them to heart as he plays with humans whenever he is bored. He gives mortals the toys to create havoc and wreak mayhem in the mortal realm. It’s all good if it gives him a moment of entertainment and some juicy apples, must not forget the apples. Ryuk is a Shinigami (a God of Death) and a monster. He usually stays in the Shinigami Realm, eating dried up apples and sometimes plays games with the other Shinigami. But being an almost immortal being is boring, so he sends his Death Note to the mortal realm from time to time to wreak havoc and for a time, he is not as bored as usual.

No matter what anyone tells you, a demon makes one hell of a butler. Because, once you make a deal with a demon, that demon does anything to see it to the end. For, once a demon forms a contract with a human, that human’s soul belongs to the demon. Ciel Phantomhive sought the power to wreak vengeance on those who have mistreated him. Those currently tormenting Ciel were dealt with quickly, but the contract wasn’t complete until all of those who mistreated Ciel were gone. Sabastian decided that it was best to be there to protect Ciel and became his bodyguard/butler. Even going so far as checking for cavities, once and only once.

Many people might argue about the number one demon on this list, for many people don’t know the true legend behind the birth of the vampires. That legend has a man, making a deal with a devil for power and immortality. Unbeknown to the man, the cost of his trade was his soul. Upon losing his soul, that man became the first vampire, a demon of the highest ranks. Who that man was, is still up for debate, but many believe that it was Dracula. That Lord of Darkness has his own spot on this list as he rules over both demons and devils alike, though he no longer goes by the name Dracula, for a new name has been fashioned for him and he goes by “Alucard” now. Some time ago, Alucard made a deal with another human, Arthur Hellsing, for some services that we do not know. It is possible that Alucard respected the human, becausewhen he met Arthurs’ daughter, Integra, he recognized Arthurs’ will in her.
