Main characters
Saya Kisaragi
Saya Kisaragi
An upbeat, cheerful, and kind girl who trains under her father as a miko and is a very skilled sword fighter. Those outside of her family are oblivious to her duty as a hunter of Furukimono, or monsters that inhabit the town.
- Action Dress Rip: Saya rips off part of her school skirt and turns it into an Eyepatch of Power in episode 12.
- Action Girl: Any scene of her fighting the Elder Bairns can tell you this.
- Adaptational Species Change: In the anime, she is implied to be a human/Elder Bairn hybrid, just like Saya from The Last Vampire is a dhampire (which is presumably the same thing in this universe). In the novelization of the series, however, Saya is explicitly said to be not a half Elder Bairn like Tadayoshi, but "a relative of the Elder Bairns, who was abandoned from another world", and it's speculated her different traits are due to having been fed with breastmilk instead of blood.
- Anti Heroine: Becomes one by episode 12.
- Badass Adorable: Despite going on missions to kill monsters she's an otherwise sweet and charming young high school girl. Though this fades once she gets her memories back.
- Barbie Doll Anatomy: Close-up during the OP. Averted in the Last Dark where her nipples are clearly seen when bathing.
- Break the Cutie: Let's just say the second half is not very kind to her.
- Broken Bird: In Blood-C: The Last Dark.
- Chaste Heroine: Other than some implied interest in one of her classmates, she has no romantic relationships.
- Chronic Hero Syndrome: In the first episode, her classmates say she is usually late for school because she goes to help lost children and grandmas and pick up trash.
- Cool Sword: Her mother's sword.
- Crouching Moron, Hidden Badass: For much of the series, she comes across as being completely inept at saving people from the monsters. Then you find out it's because she subconsciously doesn't care but could, in a heartbeat, if she truly felt like it.
- Cute Clumsy Girl: Acts frequently air-headed and keeps falling face-first while running. Though it's not a part of her true personality.
- Cuteness Proximity: Whenever she sees the dog she feels the need to stop and pet him.
- Daddy's Girl: She's very close to her fake father.
- Everyone Has Standards: Upon regaining her memories and returning to her cold and stoic personality, the sight of Nono's real death is brutal enough to make even her feel squeamish.
- Eye Scream: Aside of, you know, having half her head blown off by Fumito. Subverted in the movie, where it has been restored from before.
- Failure Heroine: Taken to a gruesome extreme. In her battles, she tries to balance killing off the Elder Bairns and trying to protect civilians. But in most cases, many people died on her watch due to carelessness on both their part.
- Fake Memories: Most everything Saya remembers that isn't from a flashback is fake.
- Freakiness Shame: Implied. In the anime, she flinches and looks absolutely heartbroken when Tokizane calls her a monster. In the movie, one of Fumito's soldiers calls her a freak, to which she responds with a very charged "shut up!"
- Girlish Pigtails: She has very long black hair tied in pigtails.
- Girl Next Door: To Fumito.
- Good Eyes, Evil Eyes: She usually has Tareme Eyes, but in her Let's Get Dangerous! moments they become Tsurime Eyes.
- Healing Factor: She has healing factor can slowly regenerate from her serious injures. Even her left eye has been completely restored in Blood C The Last Dark.
- Hidden Depths: Despite her established klutziness, Saya is REALLY good at sports.
- Humanoid Abomination: She's actually half Elder Bairn.
- Hunter Of Her Own Kind: Subverted; she does not hunt her own kind for any honorable, heroic or moral reasons. The only reason that she hunts them at all is only due to an unknown pact made long ago that forbids her from killing or devouring humans. If she could, she would have no quarrel with them.
- Of course, this is all according to Fumito, who is far from a reliable narrator. He speculates that Saya was tricked into some sort of pact to keep her from killing humans. However, Saya herself seems to have something of an affinity for them, as in the movie multiple characters point out, her Only Friend is a human girl Saya keeps going out of her way to save. Saya even shields her from an Elder Bairn at one point, taking a hit in her place that, while not lethal, was obviously painful, and going out of her way to assure Mana that it wasn’t her fault. Many people note that for all her prickly, standoffish exterior, if Saya truly didn’t care, she could easily have left Mana behind to die several times.
- The Demonic Moonlight manga revealed that the Ottomans were the ones who first found Saya and made her a protector of humanity. According to Lucy, Saya never resisted that role and does care about humans. It's just that after the danger was gone, the humans became paranoid of her, and Saya felt betrayed by how she became a tool to humans.
- I Just Wantto Have Friends: Heavily implied. After Fumito dies in the movie, Saya wonders aloud why she is always alone.
- "I Know You're in There Somewhere" Fight: When Fumito pits Tadayoshi against Saya, she briefly attempts to appeal to his reason. At one point it seems that she is almost succeeding, but then Fumito pushes Tadayoshi into killing Saya, which forces her to kill him.Saya: You're just being controlled by my blood! Go back to normal!
- Laser-Guided Amnesia: As part of her "game" with Fumito.
- Late for School: Usually because she sees a puppy she wants to pet...
- Magic Skirt: Tossed, flying through the air, feet first.
- Miko: Obviously, being the town's local shrine maiden.
- Missing Mom: Her mother died when she was a child. Or so she thinks.
- Mysterious Past: Judging for the flashbacks and their voice-overs, before the events of the series Saya worked for the United States government, presumably as an Elder Bairn hunter. The Demonic Moonlight manga confirms it.
- Nice Girl: Saya is a bright, cheerful, kind, and al friendly person to everyone and everything around her. However, It is later revealed that she is far from this.
- Nominal Heroine: In Blood-C: The Last Dark (and quite possibly the show itself), Saya only sides with SIRRUT to further her quest for vengeance against Fumito.
- Not So Stoic: Whenever Fumito is involved Saya completely looses her cool and fly's into an uncontrollable, homicidal rage.
- Oblivious to Love: As the twins point out, she really can't tell when a guy is interested in her.
- Pet the Dog: The movie might be described as an extended Pet the Dog moment for Saya, at least when she’s not raging against Fumito. Saya takes an unusually active roll with Mana. Not only does she save the girl, and always make sure she’s safe, but Saya also comforts her over her father’s death. There is even a moment where, after Saya takes a hit that would have eviscerated the young girl, Saya shows Mana her Healing Factor, so she won’t feel guilty about Saya getting hurt.
- Raven Hair, Ivory Skin: Has the qualities and is noted to be quite attractive. In fact, once she's revealed to be part Elder Bairn, her teacher comments on her inhuman beauty.
- Red Eyes, Take Warning: Usually means she's going to kick some ass or drink blood.
- Single Woman Seeks Good Man: She "loves" Fumito because he's a Nice Guy.
- The Stoic: When she learns of the "Truman Show" Plot.
- Survival Mantra: In the first episode, she utters a Shinto prayer as one.Saya: Ikutama, Tarutama, Tamatamarutama. Amenotokotachi no Mikoto, Kuninotokotachi no Mikoto. note
- Tragic Heroine: She had been brainwashed and gaslighted throughout her life. Even though she finally kills the guy who tormented her in the movie, it turns out that said guy is in love with her and everything that he did is for her survival, regardless that he tormented and killed a lot of people along the way. In the end, Saya feels alone.
Tadayoshi Kisaragi
Tadayoshi Kisaragi
Voiced by: Keiji Fujiwara (Japanese), Bill Jenkins (English), Alfonso Vallés (Spanish)
Saya's father and the priest at the shrine where he and Saya reside.
- All There in the Manual: The manga Demonic Moonlight shows his past as an Elder Bairn hunter named Kagekiri.
- Birds of a Feather: Non-romantic example. His half-human nature made him sympathize and get along with Saya.
- Brainwashed and Crazy: While under the influence of Saya's blood during their fight in episode 12.
- Half-Human Hybrid: Half-Elder Bairn, just like Saya.
- Hero of Another Story: He had his own adventures in the Demonic Moonlight manga with David, the American soldier who was his partner.
- "I Know You're in There Somewhere" Fight: Saya briefly attempts this while fighting Tadayoshi, but she fails.
- Panthera Awesome: His One-Winged Angel form looks something out of ThunderCats. Strangely enough in his youth, young Kagekiri met this type of Elder Bairn who tried to protect him. How he got this form is unknown.
- The Stoic: His personality; he shows little to no emotion. In his past, he happens to be expressive and jubilant though David's death and his alliance with Fumito show how much he had changed.
Fumito Nanahara
Fumito Nanahara
Voiced by: Kenji Nojima (Japanese), Robert McCollum (English), Cesc Martínez (Spanish)
Saya's neighbor and the owner of Guimauve, a coffee shop near Saya's home. Actually the current leader of secret organization Tower and mastermind of the series's events.
- Ambiguously Human: His eyes flash red just like Saya's in the third trailer of the movie The Last Dark, hinting at this. Effectively, he is revealed to have tried to become an Elder Bairn like her before starting his experiments.
- Anti-Villain: All the deaths, deception and betrayal of the series happened because he wanted to save Saya from a fate of starvation due to the extinction of the Elder Bairns, her only source of food.
- Betrayal Insurance: He was aware that chances Kanako would betray him were high, so the talisman he gave her to protect her from Elder Bairn attacks was fake the entire time, while he only gave Tokizane and the Motoe twins fake talismans after their first deaths.
- Big Bad: He set up the entire town as part of a "game" with Saya.
- Bastard in Sheep's Clothing: That nice cafe owner is a royal douchebag.
- Dissonant Serenity: Not matter what happens around Saya, he is always serene and kind. Not even when he drops his facade.
- Driven to Suicide: Stabs himself with Saya's sword upon failing at all of his goals: he was incapable of being the same as Saya, he could not enable her to feed on humans, and his attempts of making new Elder Bairns for her to feed on failed.
- The Dulcinea Effect: In a strict sense: despite being in charge of the covenant between humans and Elder Bairns in Japan, he became passionately fixated on saving a half-Elder Bairn who worked for the United States government and who didn't even know him in the first place.
- Expy: Of Solomon Goldsmith from Blood+, both in looks and personality. Also, much like Goldsmith, Fumito acts out of love for Saya, and is also inhuman.
- Fiction 500: Given all the things he does during the show and the film, he may as well be one of the richest people in Japan, or even the world. In the show, he's able to build an entire town from scratch just so he could run his experiments on Saya, hire what seem to be a few hundreds of people to act as the main cast and extras of his "Truman Show" Plot, and is enough influent to be able to make someone governor of Tokyo as a reward for their work (which happens in the film), and to expunge someone's criminal record (which the audience is never shown, but at that point, there's no reason to believe he couldn't do it); in the film, he's shown to control a MegaCorp named Seventh Heaven and a secret organization named Tower, and he still can pour what are probably millions of yens in experiments to create new Elder Bairns from humans.
- Human Resources: His first goal is to create Elder Bairns from humans so that Saya, who refuses to feast on humans and instead feasts in her own kind, would never run out of her food supply. As it failed, he instead tried to make her feed on humans.
- Karma Houdini Warranty: He gets away for all the atrocities he committed in the TV series. However, in the movie, he is unable to get exactly what he wanted in the first place which is to restore Saya's ability to feed on humans and to be with her forever. In the end, Fumito never gets the girl who he loved.
- Love Makes You Evil: Everything he did was for Saya, even if it was because of his own obsessive love for her.
- Manipulative Bastard: Was responsible for everything involving the experiment on Saya.
- Nice Guy: Or so he seems.
- No Body Left Behind: His body turns to ash after he stabs himself with Saya's sword.
- Reasonable Authority Figure: So long as you don't betray him he'll give you exactly what you want. As Yuka was the only one smart enough to understand.
- Screw the Rules, I Have Money!: Controls the MegaCorp Seventh Heaven (called Nanahara Group in the anime's novelization) and the Ancient Conspiracy Tower.
- Self-Made Orphan: Kills both his and his cousin's family.
- Transhuman: He tried to become a being like Saya in order to be with her, but he failed.
- Walking Spoiler: The biggest one in a cast full of them.
- Yandere: For Saya. He's willing to kill people for the sake of finding a way to restore her ability to feed on humans.
Ukishima citizens
Nene and Nono Motoe
Nene and Nono Motoe
Two wacky twin sisters who are Saya's schoolmates.
- Adaptational Nice Guy: Nene doesn't screw Nono over in the manga adaptation, with both twins being crushed to death instantaneously at the same time instead.
- Bitch in Sheep's Clothing: Implied pimps, and complete jerks.
- Creepy Twins: After dropping the facade.
- Cruel and Unusual Death: After being caught trying to defect by Fumito and the Elder Bairns, Nene is reduced to a smear on the ground while Nono gets slowly torn in half crotch-first before being eaten.
- Dirty Coward: Nene, for sure. When her and Nono are being pursued by an Elder Bairn, she betrays her twin sister by elbowing her into its path, causing Nono's violent death. Not that it helps, however; Nene is caught soon after and suffers an even more agonizing and humiliating fate.
- Eviler than Thou: While both are bad, Nene shows herself to be worse than Nono, first willingly letting herself be possessed by an Elder Bairn in order to slaughter people and fake her death, then later when she betrays Nono and leaves her to die to save her own ass.
- Genki Girl: Both of them are highly energetic. This is actually not an act, and part of their real personalities.
- Half the Man He Used to Be: Nene's true death plays out like this as she is caught by Cerberus, who picks her up by the legs and pulls until she pops apart like a wishbone before devouring her.
- Helpless Kicking: As she is being picked up by the Cerberus Elder Bairns, Nene pathetically kicks with her free leg, even weakly tapping it against one of creature's appendages. Naturally this is useless and she gets ripped off by one of her legs.
- Identical Twin ID Tag: The braid in their hair is the only way to tell them apart - Nene's is on the left side of her face and Nono's is on the right.
- Metronomic Man Mashing: Nono gets smashed into a pulp on the pavement. Almost a mercy kill in comparison to her sister's fate...
- Karmic Death: Nene lets one of these, for knocking Nono to the ground to try to save her own hide. While they both die, her death is more drawn out and painful, whereas Nono dies the fastest out of anyone there. Also there's the fact that Nene is torn in half... a fitting punishment for betraying Nono, her other "half".
- Noodle Incident: We learn that they did something bad in the past and they were jailed for it. We get a clue in episode 12 when they say that the fake uniforms are cute and that they should get a bunch for "the girls" to wear, implying that they were pimping out a bunch of girls and got caught for it.
- Pushed at the Monster: Nene does this to Nono, elbowing her in the face and knocking her to the ground to save her own hide. It doesn't help her in the end, as she gets an even worse death than her sister.
- Single-Minded Twins: They frequently do this but it's mostly an act.
- Synchronization: Often speak in unison.
- Theme Twin Naming: Their names are basically the same, you just have to interchange the Os with Es or vice versa. Of course, it's not their real names.
- Trickster Twins: The Reveal paints them as this.
- Twin Switch: Which one is Nene and which one is Nono at any given point is almost impossible to tell since they can easily switch places depending on how they braid their hair.
- Twincest: They seem about ready to kiss each other as a demonstration to Saya in episode 2.
- Vague Age: This could apply to other chatacters as well, but the reveal that Yuka is actually 28 years old rises the question of if the twins are really teenagers or not. They look too young to have already been arrested for being pimps, which could indicate that they are actually Older Than They Look, but some of their dialogue after The Reveal points to them being actually the age they look.
- With Friends Like These...: Turns out that in Episode 12, Nene's love for Nono was not quite as genuine as it seemed seeing as she easily elbows her own twin in the face to the ground and uses her as bait in an attempt to escape from Cerberus to save her own skin. It doesn't work.
- You Have Outlived Your Usefulness: Trying to cross the boss gets them this treatment.
Yuka Amino
Yuka Amino
A mature classmate of Saya's who often has lunch with her.
- Karma Houdini: Never receives any form of punishment for her involvement with the "Truman Show" Plot, and even becomes Governor of Tokyo during Blood-C: The Last Dark, exactly as she planned.
- Older Than She Looks: She's 28 years old, to be exact, but can pass as a high school student.
- Only Sane Woman: The most down to earth of the group and often scoffs at the others' antics, particularly Saya and the twins. She's still this after the reveal, being the only actor who was smart enough to not betray their employer.
- Opportunistic Bastard: Implied, much more heavily in the stage play. Fumito dies and she is seen revoking the Youth Ordinance Bill, probably just for the sake of good publicity.
- Sole Survivor: The only member of the group who wasn't dumb enough to betray Fumito, and not being a townie Red Shirt, is what keeps her from meeting the rest of the town's fate. This is lampshaded by Fumito himself.
Itsuki Tomofusa
Itsuki Tomofusa
Voiced by: Atsushi Abe (Japanese), Chris Burnett (English), Carlos Lladó (Spanish)
The class president. He has a crush on Saya.
- Becoming the Mask: He was told to pretend that he loved Saya... and fell in love for real.
- Betty and Veronica: The Betty to Tokizane's Veronica and is ultimately the one who ends up genuinely falling for her...fatally.
- Class Representative: His role in the class.
- Dogged Nice Guy: To Saya.
- Dying Declaration of Love: To Saya despite that he's just playing the role as one of her crushes.
- Loving a Shadow: While Itsuki is dying after being shot multiple times, he confesses his love for Saya, saying that, while his affections for her started as an act, he fell in love with her for real. Saya tragically points out that the person he loved wasn't even her real self, but Itsuki takes comfort in his belief that the personality Saya showed while being manipulated by Fumito was at least a part of her real self.Saya: That wasn't me.
- The Mole: According to Kuroto in Blood-C: The Last Dark, he was sent in as a spy.
- Punished for Sympathy: Is gunned down by a soldier not even half a second after trying to help Saya.
- Senseless Sacrifice: Considering Saya's healing abilties his death was pretty much pointless.
- Sheep in Sheep's Clothing: The only decent participant in the "Truman Show" Plot.
- Taking the Bullet: The reason he died is that he took a mortal blow in Saya's place.
- Token Good Teammate: He's the only one of the "main cast" who's actually concerned about Saya.
Shinichiro Tokizane
Shinichiro Tokizane
Voiced by: Tatsuhisa Suzuki (Japanese), Scott Freeman (English), Dani Albiac (Spanish)
A quiet classmate who harbors a secret interest in Saya.
- The Aloner: Is often seen on his own and is slightly disliked by the other students due to his aloof personality. How genuine this trait is compared to the others' quirks is anyone's guess.
- Betty and Veronica: He's the Veronica to Itsuki's Betty and Saya's Archie or at least he acted like it.
- Bastard in Sheep's Clothing: Like everyone else around Saya, his behavior towards her is a complete facade.
- Decoy Protagonist: His aloof-nature, notable absences from school, and slowly building relationship with Saya (to the point where he is the first classmate to learn of her double life) make Tokizane out to be more important than he actually is. Even after the reveal of the entire cast being actors, we actually learn the least about him when compared to his cohorts.
- Jerk with a Heart of Jerk: At first he seems like the classic stereotype of a good-hearted Bad-Boy, in the end it turns out that that good heart never existed, and he is much worse than a simple high school Bad-Boy.
- Misunderstood Loner with a Heart of Gold: What he appeared to be at first. Anti-social? Check. Usually late for class? Mmm-hmm. Appearing to not give a damn despite his faked crush on Saya? Oh yeah. He was really milking the feigned bad-boy stereotype.
- Off with His Head!: Thanks to a Giant Foot of Stomping from an Elder Bairn.
- Only in It for the Money: And his greedy nature bites him in the end.
- Screw This, I'm Outta Here: He tried to pull this by helping reveal the ruse of the show too soon in the hopes that he would get his payment for his services as promised and be able to escape the high maintenance risk of being eaten by the Elder Bairns.
- Tall, Dark, and Handsome: Comes off like this all the time. But it's really just to attract Saya's attention.
- You Have Outlived Your Usefulness: Cue the beheading.
- You Monster!!: Straight up refers to Saya as a monster and a freak, and even goes so far as to say that she's one of the reasons he wants to leave the show so badly.
Kanako Tsutsutori
Kanako Tsutsutori
Voiced by: Miho Miyagawa (Japanese), Lydia Mackay (English), María Rosa Guillén (Spanish)
Saya's homeroom teacher.
- Be Careful What You Wish For: Kanako wanted to be part of the experiment so she could get proof that Saya exists, witness a real Shrovetide, and publish her research and proof that she wasn't just a lunatic. After Saya kills the Elder Bairn that was trying to eat her, she is completely terified by her, and runs into the temple to Tadayoshi, only to be killed by him immediately.
- Bitch in Sheep's Clothing: Is pretty quick to change personalities when she ends the experiment and treats Saya as nothing but a prize and research subject.
- For Science!: She only agreed to Fumito's "game" for the opportunity to experiment on people and Elder Bairns.
- Helpless Kicking: As she is being lifted up and about to be devoured by the Cerberus Elder Bairns, she flails her legs like crazy and tucks them up under her butt as she's being lowered into its jaws. Fortunately for her, Saya kills it before she gets eaten.
- Hot Teacher: Boy, howdy...
- Psycho Lesbian: She appears to have a twisted attraction to Saya, outright groping her in episode 11.
- The Starscream: Willingly betrayed Fumito and gave Saya her memories back for her own ambition of exposing Saya to the world and making sure all the research and hard work she did wouldn't go to waste.
- You Have Outlived Your Usefulness: She managed to survive the Elder Bairn that Fumito had tried to kill her, only to end up dying at the hands of Tadayoshi's Elder Bairn side.
- They Called Me Mad!: Brought up during her Motive Rant and considering the lows she stooped to make Saya her research subject, they were probably right.
SIRRUT
Kuroto Mogari
Kuroto Mogari
An internet mogul who leads the SIRRUT organization against Fumito.
- Big Good: As the leader behind SIRRUT. Even after his death, the member still regard him as this thanks to Saya being the only whitness to his true nature.
- Eye Scream: Towards the end of the film, Fumito jams a vial with Saya's blood into his left eye.
- Forced Transformation: Fumito turns Kuroto into an Elder Bairn against his will.
- Genius Cripple: Wheelchair bound, but head of the number one IT venture company Sysnet. Actually an Evil Cripple.
- Gory Discretion Shot: Averted. The audience gets to see his eye get a vial of Saya's blood jammed into it in rather graphic detail.
- Mole in Charge: He actually works for Fumito and is actually his cousin who joined Fumito as part of a plan to kill each other's families and use the power of the Tower to take control of the world.
- The Starscream: Tries to off Fumito to gain sole control over the Tower. He did expect Fumito to survive and turn him into an Elder Bairn
- Unreliable Expositor: Reveals that Fumito massacred his entire family. Only for it to be revealed that the two of them were in on it together.
- White Hair, Black Heart: White haired and a complete bastard.
Mana Hiiragi
Mana Hiiragi
Voiced by: Ai Hashimoto (Japanese), Jad Saxton (English), Nuria Trifol (Spanish)
A 17-year-old hacker and member of SIRRUT.
- Achilles in His Tent: She’s the best hacker SIRRUT has, but losing her father has caused her to withdraw from the team. It’s only when Saya shows that she gets over her issues enough to once again go after Fumito.
- Ambiguously Gay: She is never explicitly said to be a lesbian, but she becomes attracted to Saya in a very obviously romantic way.
- Birds of a Feather: With Saya. Mana realizes that part of the reason she wants to be around Saya all the time is that she intuitively recognizes her as a kindred spirit. Namely, they're both hurting heroes who lost people they loved and feel responsible for it.
- Brainy Brunette: Has brown-haired and knows a lot about computers.
- Broken Bird: She tried to help her father get a lead on Fumito, but ended up sending him to his death. Needless to say, she’s in pieces about her apparent role in her father’s death.
- Locked Out of the Loop: She never learns that the Elder Bairn that Saya killed was her father or that Kuroto was actually in league with Fumito.
- Morality Pet: She acts as the moral crutch for Saya due to her experience of losing her father.
- Nerd Glasses: Mana is a very competent hacker at the age of 17 and she uses a pair of round glasses.
Iori Matsuo
Iori Matsuo
Voiced by: Yūichi Nakamura (Japanese), Justin Cook (English), Ángel de Gracia (Spanish)
SIRRUT's driving expert.
- Badass Driver: Pulls off some very impressive feats with his car.
- Japanese Delinquents: Gives the vibe, always wearing combat boots and a headband.
- Jerk with a Heart of Gold: Frequently complaining and mistrustful of Saya, but he's just as devoted to SIRRUT's cause the rest.
- Pair the Spares: At the end of the film he and Haruno Yanagi are engaged and running a cafe together.
Shun Fujimura
Shun Fujimura

- Gender-Blender Name: Hiro is almost always a male name in Japan.
- Hair of Gold, Heart of Gold: A sweet blonde girl.
- Handy Feet: She is skilled at typing with her toes, and even wears toe socks to ease it.
- Kiddie Kid: Not overtly, but she is sensitive and whimsical, likes cute things, and it seems other SIRRUT members see her as an Adorably Precocious Child. It only increases considering she canonically shares universe with girls like Kohane Tsuyuri.
- Older Than They Look: Slightly. She is 13, technically a teenager, but you are forgiven if you thought she was around 10.
- Playful Hacker: She seems to spend as much time goofing around in internet as hacking for SIRRUT.
Haruno Yanagi
Haruno Yanagi
Voiced by: Yuko Kaida (Japanese), Colleen Clinkenbeard (English), María Rosa Guillén (Spanish)
Kuroto's secretary in Sysnet and right hand in SIRRUT.

Others
The Dog
The Dog
Voiced by: Jun Fukuyama (Japanese), Todd Haberkorn (English), Jordi Nogueras (Spanish)
An unusual puppy with strange marks on his body who is usually seen near Saya, who finds that it can actually speak.
- Ambiguously Human: He does everything but saying outright that his dog form is actually some sort of disguise. An avatar, in fact, for Kimihiro Watanuki.
- Deadpan Snarker: Though not exaggeratedly, he does react to Saya's denseness.
- Facial Markings: Has three marks in his forehead.
- Mentor Mascot: Acts as somewhat of this to Saya, leading her to ask herself important questions.
- Shout-Out: He states he owns a shop where wishes are granted, hinting at the possibility of being Kimihiro Watanuki from CLAMP series ×××HOLiC (who Jun, Todd and Jordi also voiced). This eventually becomes true in the movie.
- Talking Animal: He's a small dog who regularly converses with Saya. Subverted when it's revealed that he's simply a medium used by Watanuki to communicate.
The Elder Bairns
The Elder Bairns (The Furukimono)
A race of ancient creatures that feed on humans in Japan.
- Brainwashed and Crazy: Fumito had them imbued with Saya's blood and some special magic so he could control when they would attack.
- Eldritch Abomination: They are an ancient and powerful race of monsters, who exist solely to eat people. They are all born with different shapes, which makes them impossible to kill, and the only way to defeat them is with one of their own kind.
- I'm a Humanitarian: They must eat humans to survive. For this reason, a covenant was made between them and man to ensure humanity wouldn't be wiped out.
- Our Vampires Are Different: While not outright evident, as they usually eat their prey whole, it seems that blood is their most nutritious part for them. In fact, Saya, a half-Elder Bairn, only feeds on blood.
David
An American military investigator sent to investigate some gruesome murders in the Yokohama base in Japan in 1946. He appears in the manga Demonic Moonlight.
- Adaptation Origin Connection: Inverted; compared to the original David from Blood: The Last Vampire, who was Saya's handler, this version of him is much less important to Saya's past given that she served a different U.S. agent.
- Adaptation Relationship Overhaul: Unlike the previous incarnations of David who was Saya's handler and is close to her, this David is never an acquaintance to Saya and only meets her due to working for another US agent.
- Age Lift: The David from Blood looked to be in his sixties at the movie's time, which takes place in 1966. This version of him, however, was born in 1920 according to his grave, making him comparatively younger.
