The titular character of the series. She is the second royal princess, daughter of the king of all monsters. She appears as a young aristocratic woman wearing Gothic clothing. Her real name is Lilliane but she dislikes people calling her by it. Although her siblings are busy fighting for the throne, she shows no interest in it. She resurrects Hiro on a whim after he dies, thinking him interesting enough to be her servant.
… You’re quite strong, Your Highness. You still haven’t escaped from the effects on your body… you should be in so much pain that you cannot stand, but your firm posture… You really are wonderful, your Highness…! It’s all because of you. Your soul is so noble, we have to take you in no matter what…!
Rich in Dollars, Poor in Sense: Hime is an Sheltered Aristocrat, so she never helps with any work that doesn't involve killing something. She also didn't know how to use a modern cell phone - Hime stated that Flandre to use it for her. This also explains why she is always reading when everyone else is playing videogames.
Royals Who Actually Do Something: Played with. Hime has NO interest in the throne. But when she gets attacked, Hime is just as likely to fight back as Hiro is to protect her. Also, she will protect and assist her "subjects" and the local town.
The protagonist who dies at the beginning of the series (in the manga he was hit by the station wagon Flandre is driving, whereas in the anime he is hit by a falling iron pillar). He finds himself in Hime's service as he is bound to her because her blood revived him. Though young and not very strong, Hiro manages to assist Hime (mostly by being a human shield) through his "half-immortality" that was given to him after his resurrection.
Badass Adorable: The few times he's spotlighted, he's so unsure of himself or worried about Hime.
Flat Character: There isn't much character development to him outside of learning the ways of the monster world. Half the time he's just following Hime around or happens to be in an area of monster activity.
A half-breed tomboy girl who has a werewolf father, called Volg Wildman, and a human mother. Being of mixed blood, Riza can only transform her arms up to her elbow and her physical combat capabilities can't compare to that of a pure breed, though she is many times stronger than a normal human.
Gamer Chick: Plays with Hiro sometimes. Ironically, she Doesn't Know Mortal Kombat (Hiro says she never bothered to read the instructions). She even lampshades the irony that Hiro is good at the game but, at this point in time, is useless in real life.
A female vampire who attends the same school as Hiro. She has long black hair, always dresses in a dark sailor fuku, and has idol status in her school. At first, she greatly detests Riza but their relations change gradually for the better. Other than the blood from Royalty, she also prefers blood from virgins, girls and "cute" guys.
She even compliments Hiro when he has to dress as a girl.
Combat Pragmatist/Lovable Coward: She's braver and a bit more loyal than most vampires, but she is not above fleeing a fight if it's going badly for her. She will, however, always run towards a non-combat solution to the problem. Even if that's "find someone who can fight."
Expy: With Princess Resurrection only pre-dating Hell Girl by a few months, it's probably just a coincidence, but doesn't a certain other black'n'red-Joshikousei-wearing, supernatural, pretty girl with a Hime Cut and red eyes rather resemble Reiri?
In personality and body form, Reiri is quite far from hellgirl, as hellgirl is more to stoic lolita and Reiri is a lively bisexual adult vampire.
In fairness, the black seifuku with himecut doesn't come from hellgirl and at this point there are so many characters using it as it supposedly turn into a trope of it's own.
Lesbian Vampire: Hasn't been actually stated, but there's enough evidence...In fact, when her 'old friend' Greta visits her, she and Reiri greet eachother by clasping hands and stroking one another's faces.
Panty Shot: Reiri flies around a lot, and we are treated to a plethora of shots from beneath her.
Hell, we even get flashes from a normal angle. Must be windy in Sasanaki.
The Starscream: Subverted; she's rather loyal, even though she'll tell you she isn't. To the point of taking The Slow Path into a Bad Future and getting killed in order to give Hime a message to send back in time. This surprises a lot of Royals, as vampires do not make for loyal servants.
An "evil" spider deity initially responsible for the disappearance of students at Hiro and Reiri's school, she is eventually stopped by Reiri and Riza. After failing to get back at the pair (and by extension Hime, for being their patron), she settles into a sort-of cooperative relationship with the residents of Hime's mansion after the latter builds a shrine to her in the mansion's backyard. Is pretty much the de-facto guardian deity of Sasanaki at the moment.
Cthulhu Mythos: Hinted to be Atlach-Nacha, with the spider theme, and the name, also the part where she is bridging a chasm between worlds.
Defeat Equals Friendship: She tries to trap Hime and her entourage in prehistoric times in response to Riza and Reiri impeding on her human offerings. This fails. Later on, when her temple is destroyed, Hime allows her to set up on her new temple in Hime's backyard. She has two spider servants, Jiroumaru and Taroumaru.
I'm a Humanitarian: She clashes with Hime, Reiri and Riza on this. Not that it makes her a bad person. She was just taking 'offerings' as she has to eat. Now, she accepts offerings from a little shrine...though she complains about how Sawawa makes them.
Jerk with a Heart of Gold: she's not nice but she doesn't eat people out of malice. She also displays genuine, if grudging, concern towards Hime and her group. Plus, she has a soft spot for Sawawa.
Hime's younger sister. She once harbored bad feelings towards Hime, but later reconciled, and has a rather obvious crush on Hiro and will almost do anything to make him her servant. After that she moved in to a mansion on the hill opposite Hime's mansion.
Disney Death: In chapter 77 due to exposing her body to the spore cloud and adapting to it, fresh air become lethal to her and she nearly dies if not for Hime saving her with her newfound phoenix power.
My Sister Is Off-Limits!: While it's not so surprising that Hime and Emile refused to kill her, Sherwood muses that the only reason she survived is because most of her siblings were too noble to take the direct route and just straight-up murder her.
Reality Ensues: Sherwood doesn't even try to hide Ryu, and nobody calls her out on the fact that owning a panda as a pet is illegal. Until chapter 35, where she's arrested for violating the Washington Convention.
One of Hime's siblings, a self-important coward who will use any means to remain the last one standing. It is hinted that he was the one who ordered the attack that decimated Hime's forces prior to the story via unleashing a Zombie Apocalypse on her holdings, and he tries to do so again.
Bad Boss: His blood warrior, Mikasa, is a woman he killed himself.
The Black Sheep: Of the family. Hime doesn't always have a winning personality, but she and Sherwood are ultimately kind hearted and noble people. Emile is caring, loyal and brave, and Gilliam is respectful to his followers and an honorable warrior. While she is utterly ruthless, vain, arrogant and a bit cruel, Silvia is not wantonly sadistic and doesn't really cause collateral damage. Severin is a cruel, nasty little coward who causes tons of needless deaths to get what he wants.
Severin's blood warrior, Mikasa is a woman that Severin killed then revived via his blood. Mikasa is much more deadlier than your usual Blood Warrior, by virtue of the "modifications" done on her by the Fly Man. At Severin's death, she becomes Silvia's Blood Warrior instead.
Mix-and-Match Critters: Severin had her body modified while she was his blood warrior. Fly Man is also doing some experiments on her.
An anthromorphic fly scientist. He is first introduced trying to "sell" the fruits of his research to Hime (meaning he took her hostage to force her to buy them from him, or die if she refused). He works for Severin at first, but Silvia eventually becomes his financial patroness, and as such he makes things on her request, whenever he isn't pursuing his own independent research that is.
Quiet and brooding, Emile is one of Hime's older brothers. Seemingly plagued with a weak consitution, his powerful Psychic Powers, including telekenesis and limited clairvoyance, more than makes up for this. Like Sherwood he is not openly antagonistic with Hime, but will not aid her either (directly anyway).
Shoo the Dog: Thanks to his Psychic Powers, he seems to do this twice in one shot: upon realizing that his plot to become an adult and end the succession fights failed, Keziah and Sledge are killed, the mermaid becomes Silvia's blood servant. Emile resurrects Keziah with fire magic for the express purpose of making the mermaid into a Flame Warrior. When Keziah fulfills his purpose, royal blood becomes useless to the mermaid and Keziah himself dies immediately afterwards. Thus none of his servants are in play for the upcoming war between the Royals.
A werewolf warrior first encountered stranded in the Ghost Ship, Keziah is one of Prince Emile's loyal servants. He was a companion of Riza's father in the old days, and as such, despite being technically Riza's enemy, tends to look out for her whenever they cross paths.
A winged warrior of an unspecified humanoid race, Sledge is another of Prince Emile's bodyguards, serving opposite to Keziah. Despite being in the same faction, they tend to bicker with each other when left alone.
Flanders is the robot bodyguard assigned to serve Emile. Unlike his "siblings" Flandre and Francesca, Flanders is a Humongous Mecha on the scale of kaiju-sized monsters. He is later upgraded to Flanders G.
Foreshadowing: The fact that Flander's head-mounted photon cannons are used by Gilliam is a big clue that Emile has already died
A mermaid that was trapped on a ghost ship, and was used by the malevolent entity there to lure in other ships to their doom. In return for gaining the ability to walk on land, she had willingly given up her voice, but in the process she was cursed that she would die if she ever spoke. She is eventually rescued from the ghost ship by Hime's friends and Keziah, but not before she speaks up to warn the latter. This causes her death, but she is quickly revived via Emile's blood, becoming one of his Blood Warriors.
Adaptation Dye-Job: Despite her hair being a dark color in the manga, it becomes pink in the first anime. The OVA rectifies this somewhat, turning her hair back into a very dark blue.
Only Known by Their Nickname: She is referred to through the manga and the OVA simply as "ningyo", which literaly means mermaid. It is only later in the manga that we learn that her real name is Madeline.
The eldest princess, Silvia is beautiful, elegant, and charismatic. She is also incredibly cunning and willing to do anything to come out on top of the current succession war, without directly showing her hand of course. With this in mind, she is likely the most dangerous of Hime's siblings prior to the emergence of Prince Fuhito, that is.
Another of Hime's older brothers, Gilliam appears as an intense-looking man in a white suit, and is always seen with his sword close at hand. Unlike his brother Emile, Gilliam is much more brash, and isn't shy to prove how good at using his sword he really is.
Badass: His fight with Hime, Reiri and Hiro in the 2nd OVA.
Hoist by His Own Petard: On the giving and recieveing end. He blasts Hime's mansion with a particle cannon for fighting him earlier, using the very weapon she used then on him. He then is about to blast Sherwood's mansion, proclaiming "karma's a bitch", only to be blasted, but not killed, by Hime with the same cannon.
By chapter 78 and 77, he gets desperate and willingly exposes himself to an alien spore cloud in hopes of fighting and defeating Fuhito. This winds up backfiring as prolonged exposure means he can't survive in fresh air. The spore uses him to explain to the others that they meant no harm and were just trying to find a new home before heading out into space. Clearing away the mist and killing Gilliam in the process. He is graceful about it though and, like Emil, wishes for Hime to be the next ruler as she gave him a royal death.
The oldest royal sibling alive, Duken was supposedly the winner of the previous generation's succession war by default, as his only other remaining rival had gone into hiding. However instead of being elevated to maturity, he was instead passed over by the other Elder royalty, which indirectly leads to the current succession war. In reality Duken had been killed decades before by his brother Prince Fuhito, and the "Duken" seen by the other siblings is simply another android.
The creator of the humanoid bodyguards that serve the royal siblings, Dr. Franken considers himself a neutral observer to the succession war. As such his mansion is considered a demilitarized zone where the royal siblings can talk with each other without fear of attack or betrayal.
BadAss: Chapter 70 shows that, prior to his current state, he can actually defend himself quite well.
Another royal prince, Fuhito's unexpected entry into the succession war has shifted the power balance between all his other siblings. Although looking for all the world like a young boy, Fuhito is an extremely powerful esper... and he isn't hesitant in using that power. Fuhito was actually a participant of the previous generation's succession war, though he had to go into hiding due to the toll the battles took on his body. It was he who killed Duken, and had him turned into a robotic body-double, which in turn indirectly causes the current generation's succession war.
Bigger Bad:Subverted. He's brought up like this, but Silvia ultimately usurps the role of Big Bad back from him.
