Kurumu Korono is a demon girl with the heart of an angel. She is a student at Yokai Academy and is deeply in love with Tsukune Ano. She’s also a succubus. You’d imagine that it would be easy for her to ensnare Tsukune with her aphrodisiac powers, but he makes the decision that getting him to love her through magic is wrong. She wants him to love her because of who she is, not because of a spell. She is one of the most honest characters in the series and one of the most dependable ones, too. Kurumu is always the first to throw herself in front of danger to protect her friends. She cute and sexy all rolled up into one. She has a killer body yet wears a baggy sweater and loose-fitting socks that gather around the ankles. Kurumu even wears a blue ribbon that matches her blue hair. You combine her cute appearance, sexy body, loving personality and the fact she can bake you all the muffins and pastries you want and you get a succubus that doesn’t need any special powers to entice your devotion.

Ai Enma is very different than most of the girls on this list. She is, in fact, an actual demon spirit and a servant of Hell in the way most of us think of Hell as a place of punishment. Ai, which ironically can mean love, is a quiet girl with long black hair and red eyes. She is often seen wearing a black seifuku, or sailor uniform. Her work as a servant of Hell is a form of atonement; Ai was sacrificed to a mountain god centuries earlier by her village, but she dug herself out of her grave and burned all the villagers alive. She is now summoned by those who think they’ve been done wrong. In exchange for their souls when they die (naturally), she’ll drag the other party to Hell immediately. Her personality seems a little detached but the more you watch her story she seems like she still has feelings and is looking for excuses, or just hoping that people will choose not to contract with her. Her fate of being punished for exacting a just revenge is tragic and leaves you hoping that there’s some way she can find happiness.

Elsie has a similar job as Ai from Hell Girl in that she sends spirits escaped from Hell back, but she’s a complete 180 personality-wise. She is a bubbly, earnest and sweet girl. Elsie teams up with Keima, a high school student and dating sim master, in order to expel spirits from teenage girls by filling the holes in their hearts with love. In many ways she is a go-getter, working her way up from janitor in Hell to soul-catcher, though it did take her 298 years. Elsie has a good heart, despite causing problems for the people around her. An example of that is she tells Keima’s mother that she an illegitimate child of her husband’s in order to stay with Keima in the role as his little sister. Keima’s mother accepts Elsie right away, then goes off to beat the Hell out of her traveling businessman husband. Despite being a bit of a dork, Elsie is good at her job. Elsie and Keima collect loose soul after loose soul and she looks adorable doing it.

Lilith Asami is a teacher at the top-secret magic school Royal Biblia Academy. The academy’s job is to train mages to stop what is known as the break down phenomena, a magical plague that dissolves organic matter and had spread over the world. Her job, as a teacher of course, is to guide and train Arata, an immature, sex-obsessed mage. Lilith’s main goal is to prevent Arata from becoming a demon lord by teaching him to control his potential power. She doesn’t sound like a demon, does she? Yet, it is revealed that she is in fact Lilith Azazel, the daughter of a demon lord who had her memories erased. Hence, qualifying to be on this list as a demon. Lilith is an amazing mage, one of the most powerful in existence. She’s also a knockout with a PhD in L-U-S-T. No, we’re serious. Her thema, or cource of study, is the magic pertaining to the sin of lust. Lilith is rather prudish for a mage that studies lust and makes a great foil for the sex-obsessed Arata. She on this list for her beauty, brains, and overwhelming power as a mage.

Horns, check; spade tail, check; bat-like wings, check; malicious intent, nope; bad to the bone, not even close; Vignette April Tsukinose may be a demon by birth but she’s an absolute angel of a girl. She is the demon next door and best friend to the protagonist Gabriel, a foul-mouthed slob and MMORG-obsessed angel. Vignette does her absolute best to take care of the wayward angel by getting her out of the house and to school as often as she can. She is genuinely adorable as a demon; she doesn’t lie, cheat, or litter and is the first person to offer help if you need it. Vignette is a demon girl goody-two-shoes and we sometimes wonder what she’d be like if she let her little hellion out. I’m sure she’d do something bad like not wash the dishes right away. She is a full-blooded demon but seems absolutely divine.

Mina Tepes is the ruler of all vampires and dragged the entire species out of the coffin and into the light of day, figuratively speaking. She has arranged in a deal with the government of Japan to establish a “Bund,” an autonomous region within a state, on an island off Tokyo as a homeland for vampires. Mina is a shrewd leader. She has to be a cunning leader to assemble political power and economic might. The vampire queen has to fight factions from within the vampire world and from the human world to defend her dream of an island nation. She has several faces she shows to the world: the queen, the warrior, and the girl. We are never sure which is the real Mina. We’d like to think the real Mina is the one we see when she is with her bodyguard and lover Akira Kaburagi. She’s a smart girl who enjoys teasing the boy she loves and has a heart full of love for him and her people.

Satanichia is an arch-demon bent on conquering Hell and Heaven. She will hone her skills by not doing her homework, teasing angels, and not separating her recycling. She is truly a demon, one descendent from a long line, and ready to leave her mark on the world. The reality of Satanichia is a little different. She’s an idiot. She thinks she’s truly being evil by leaving the cap on the bottle when she recycles it. The dimwitted demon is also the perfect mark for Raphael, an angel that has a better chance of becoming a demon lord than most demons. Raphael truly enjoys toying with extremely gullible Satanichia. She’s like the redheaded dorky little sister you’ve always wanted. We even feel bad for the girl, she’s continually taken advantage of. We know she is a kind girl who’s always willing to help those in need. She may be a demon but she’s also just a dork worth mentioning in this top 10.

Mio is a beautiful teenage girl with long red hair and a fiery personality. She tends to have a bit of a short temper, but that’s understandable considering that she watched the people she thought were her parents get killed and then finds out that she is the heir to the deposed demon lord. Along with her body guard Maria, a succubus, she devises a plan to dupe a widower and his son into taking them in. They don’t realize that their marks are immune to their spells. Instead of kicking them to the curb, the father and son decide to take them in and protect them. Convinced by Maria, Mio forms a magical contract with their new step-brother Basara, a contract that will alert him if she’s ever in danger and also makes her his servant. If she disobeys him or thinks bad thoughts about him the magical contract makes her very horny. The lustful punishment is a great contrast to her conservative demeanor. Mio is most of all just a teenage girl trying to figure out who she is in this magical world recently revealed to her. We like Mio because her character develops from a scared girl putting up a front of toughness to a girl with power and the knowledge of how to use it.

Rais Gremory is the youngest sister of Lucifer, which gives her more than enough street cred to appear near the top of this list. She lives her life as an everyday high school student and the president of the Occult Research Club, a club filled with other demons. She is, as a lot of demon girls we come across, a red-head with a killer body. She does her best to take care of her friends and balance the demands of her station as a devil elite. The demons that follow her as members of the club normally have to go out when summoned by someone and do their best to grant their wishes, mostly mundane stuff like keeping someone company. We like Rais not because of her power or her aforementioned rocking body, but because of the gentleness and humbleness she shows as she wields that power. She is arguably one of the most powerful demons in the story yet cares for others and doesn’t rule like a tyrant. She treats the members of the club like a family and will do anything to protect them. Rais earns our respect, our devotion and love as an elite that understands the idea of noblesse oblige.

We’ve all had that one high school teacher we end up having a crush on and Satou Sakie is no exception. Even though she does everything she can to make herself less attractive to avoid the attention. Satou lives alone in the country; she takes the first and least-crowded train to work in the morning and home at night. She even wears a track suit, no makeup and keeps her hair in a ponytail -- all to seem less attractive. The trouble she goes through to be less appealing almost works. You see she is a succubus and emits pheromones that arouse most men and even some girls. We can’t help but like her, pheromones or not. She adorable, too. We love watching her deal with her conflicting feelings in regards to her crush and fellow teacher Takahashi Tetsuo. She is an honest and caring teacher, though she may keep her students at arm’s length for their own protection. She knows that standing too close or god forbid actual physical contact can bring on a dangerous amorous reaction in people. We love her for her self-sacrifice and living a rather lonely life all to protect us from ourselves. It’s a sacrifice that puts her at number one on this list.
