A group with the task of dealing with supernatural tasks in Japan. After the apocalypse, the JIDA comes into great power and establishes human cities in Shibuya and Shinjuku and wages war against the vampires. It used to be a paramilitary organization that serves the Imperial Demons, the magic cult established by the Hiragi Family.
Japanese Imperial Demon Army
- Badass Army:
- Creature-Hunter Organization: Earth's population is decimated by a virus, and the survivors are attacked by monsters or enslaved by vampires. Elite members of the army are able to make contracts with demons to earn phlebotinum weapons which are the only things capable of killing vampires.
- Rising Empire: Looking to become this under Kureto, who states his intention to wipe out not only the vampires but any other surviving human organizations for the goal to Take Over the World.
- Playing with Syringes: Similar to all known magic organizations, JIDA is involved in quite a number of horrific non-consensual experiments with human and vampires, children and adults alike.
Hīragi Family and the Order of the Imperial Demons (WARNING! MAJOR SPOILERS AHEAD)
- Big, Screwed-Up Family: The most powerful clan in Japan even before the virus attack and is totally screwed up. The Order of the Imperial Demons used to control the Japanese government (together with the Hyakuya Sect) before the Apocalypse. Besides practically controlling the Muggles and the government, the Family engages in orphan buying and kidnapping, media manipulation, extrajudicial killings, slavery, large-scale horrific experimentation on children and adults alike, etc. This is most evident in the prequel Light Novels.
- The Clan: The largest and most powerful in Japan. Its members are treated as living gods by the subordinate clans of the Imperial Demons.
- Feuding Families: The relationship between the Hīragi family and the Ichinose family is not exactly great.
- A Nazi by Any Other Name: The family is essentially worshiped like living gods within the Order, which is a group of sorcerers who have tremendous power over the Japanese society and Muggles (hell, a massacre in a school administered by the family occurred in broad daylight and was subsequently covered up completely, with no police or media investigation occurring at all). It condones and encourages supremacism, discrimination, eugenics, Social Darwinism and "unethical" human experimentation. Before the Apocalypse, the family even used to have a paramilitary organization that operates extra-judicially and completely obeys its whim (now known as the JIDA), not unlike the Nazi's SS. This is most evident in the prequel Light Novels.
- Puppet King: In Chapter 57, it is revealed that every head of the Hīragi Family has been possessed and controlled by Shigama Dōji, a demon who used to be the first progenitor of the vampire race.

The former General of the Japanese Imperial Demon Army and former head of the Hīragi family.
- A Nazi by Any Other Name: Consistent with the Social Darwinist and supremacist traits that runs deep in the Hīragi Family.
- Chain Pain: In Chapter 57, it is shown that he release chains from his body like Saitō.
- Eyepatch of Power: Wore a black patch that covered the right side of his face because it had curse marks.
- Family Eye Resemblance: All of his biological children have the same reddish-brown eyes as him. This makes Shinya's Icy Blue Eyes immediately stand out.
- Large and in Charge: One of the largest characters in the series and was the General of the Demon Army.
- Minor Major Character: He was the General of the Demon Army yet was rarely seen throughout the series.
- The Patriarch: Used to be head the Hīragi family before Kureto killed him in Chapter 57.
- Pride: He is best described as a proud and harsh individual.
- Sibling Murder: Killed all 40 of his siblings to become the head of the family.
- The Social Darwinist: He strongly believed in the concept of survival of the fittest. Due to the weight of this savage principle, he would have seen that the strong lived and the weak died.
- You Gotta Have Blue Hair: His hair was ashen (blueish-gray) hair that appeared more lavender in the anime.

The Lieutenant General of the Japanese Imperial Demon Army and is expected to become the next leader of the Hīragi Family as well as the Japanese Imperial Demon Army. His goal is to exterminate all the vampires in Japan, and have the world under the control of the Japanese Imperial Demon Army.
He also appears in the Seraph of the End: Guren Ichinose: Catastrophe at Sixteen light novel series.
- Aloof Big Brother: To all his younger siblings.
- Always Someone Better: His half-sister Mahiru was regarded as more powerful than him despite being younger.
- An Arm and a Leg: Loses his right arm during his fight with his father Tenri in Chapter 57. He gets it back though.
- Authority Equals Asskicking: As expected of the firstborn of the Hīragi family.
- Bad Boss: Pretty much doesn't give a crap about sacrificing his soldiers if he thinks it's worth it.
- The Chessmaster
- Entitled Bastard: He expects everyone to submit to him with absolute loyalty and as such doesn't tolerate any disrespect from lower-rank families. He later stages a coup d'etat against his superiors and kills his own father.
- Four-Star Badass: Well, he is the Lieutenant General of the JIDA and wields a Black Demon Cursed Gear.
- The Fundamentalist: Fervently believes that he's just and right in using his soldiers as blood sacrifices and attempting to subjugate the whole mankind. He says this to Narumi as he sacrifices his own soldiers in an experiment to appease Abaddon, one of the Seraph of the End.Kureto: Don't fuss. Their death was a glorious death for the sake of humanity's progress. Thanks to the few sacrifices of this experiment, many will be saved. This is a right thing to do. This... is justice.
- Green-Eyed Monster: Towards Mahiru and Guren, for both being capable of trying and succeeding in pursuing their greed and desires, something his own standards are preventing him from doing.
- Lack of Empathy
- Knight Templar: Complete with being a Well-Intentioned Extremist and The Fundamentalist.
- Manipulative Bastard
- Married to the Job
- Obliviously Evil: Doesn't seem to realize or care that if he has his way, he'd be no better than the vampires.
- Pet the Dog:
- Briefly in the Catastrophe novels where, despite having the opportunity and perhaps, even the need to torture Shinoa to coerce Guren and especially Mahiru to comply with his demands, he doesn't do so, and instead, opted to just have her put on make-up to give off that impression to them.
- And while it doesn't last long, he also offered Shinoa the chance to join him in his quest for power using the Seraph of the End. But since he just willingly slaughtered many of their comrades in front of her for the sake of his plans, she naturally refuses.
- He also seems to care enough about Aoi to a degree based on his reaction to her nearly getting hurt in Chapter 57.
- While he's still a Knight Templar about it, he seems to adhere to the idea that kings shouldn't stand alone, hence, hinting that he values camaraderie above all else.
- Pride: He is very proud and powerful.
- Self-Made Orphan: Kills his father Tenri at the end of their fight in Chapter 57.
- Ship Tease: With Mitsuba's older sister, Aoi.
- Shock and Awe: His Black Demon Cursed Gear Raimeiki (which translates as "Thunder Demon") is able to enshroud him with streaks of electricity as both a defensive and offensive mechanism.
- Smug Super
- Tall, Dark, and Handsome
- Tautological Templar
- Übermensch: Believes that he is right and will do anything to further his own ambitions.
- The Unfettered: Kureto will use any means at his disposal to win against the vampires.
- Utopia Justifies the Means: His goal is to overthrow the vampires and be the ones dominating them instead. He's also plotting to annihilate the surviving human magic organizations and subjugate the whole humanity.
- Visionary Villain
- Well-Intentioned Extremist: The "well-intentioned" part is highly debatable, but he is willing to unite humanity under the banner of the Hīragi Family by destroying all vampires and any other human organizations that survive the Apocalypse.
- Not-So-Well-Intentioned Extremist: Given his most recent actions, it is more than likely that his so-called good intentions are lies. He murdered his own father in order to claim control over the Demon Army, so his "uniting humanity under the Hiragis' banner" actually meant "uniting the world under his banner".
- You Monster!: Shinoa, his own sister, remarks that he is a monster, even though she does not say it directly to him.

A Major General of the Japanese Imperial Demon Army.
- Abusive Parents: His biological parents sold him into the Hīragi family for three hundred millions yen at the age of five. He was not only abused but also tortured and neglected.
- Ambiguously Gay: Shinya appears to have no interest in women, and his strongest connection is definitely with Guren (whether romantically or not). The fact that he seems to flirt with Guren 24/7 has not gone unnoticed.
- Interestingly, Shinya did seem to be attracted to his former fiancée Mahiru in the light novels, but not for long considering he grew to dislike her very quickly.
- His response to the question in the guidebook of what he looks for in the opposite sex is him basically saying that since Mahiru was female and he had an awful experience with her, he isn't interested in women anymore, suggesting once upon a time he might have been Ambiguously Bi.
- Interestingly, Shinya did seem to be attracted to his former fiancée Mahiru in the light novels, but not for long considering he grew to dislike her very quickly.
- Back from the Dead: In Chapter 47, it is revealed that he died 8 years ago, just before the Apocalypse happened, but was revived by Guren using the Seraph of the End power at the cost of 90% of humanity.
- Beneath the Mask: Because of his harsh, Hunger Games-esque upbringing, Shinya associates his self worth with winning and being the best. (During the gruesome selection process he developed a cheerful and polite facade as a coping mechanism.) He viewed Mahiru's rejection as his first loss, so he became obsessed with winning her over and eliminating competition. He eventually considers his ingrained competitive nature selfish after realizing (and idolizing) Guren's drive to help others. It is implied that he suffers from self loathing and probably depression over having to take the lives of other children for his own sake.
- Died in Your Arms Tonight: Chapter 54 reveals that Shinya died in Guren's arms eight years prior to the series.
- Dark and Troubled Past: His childhood was pretty much hell.
- Extreme Doormat: Acts this way around his adoptive family.
- Four-Star Badass: Shinya is a Major General and as a wielder of Black Demon Cursed Gear, he's one of the strongest human fighters in the series.
- Friendly Sniper: He is one of the few Hīragi family member who gets along with Guren. It does help that he's only adopted and not related to them by blood.
- Hopeless Suitor: Tried to get Mahiru to like him but it's hopeless because she only had eyes for Guren. And now it's switched - he tries to get Guren to like him, but he only has eyes for Mahiru. However, unlike with Mahiru, he actually has a bit more chance of winning Guren over.
- Icy Blue Eyes: Shinya's eyes emphasize his precision as a sniper and also immediately sets him apart from his adoptive siblings who share the same reddish-brown eyes.
- In Love with Your Carnage: Whether Shinya is actually in love with Guren or not is a matter of perspective, but in the Catastrophe light novel, it's pretty clear that he had no tolerance for a Guren who pretended to be a whim with a fake polite tone - in fact, he was disgusted and even called him "trash" once. It's only when Guren showed his true power and true personality that he became interested and affectionate again. In the present, it's implied that even though Shinya has to stay back to smooth things out in meetings after Guren behaves disrespectful, he's actually amused by that and finds that an endearing trait of Guren.
- Irony: Shinya was Mahiru's fiance, and Guren was in love with her. You would expect them to fight each other over her, but no. They actually joined forces to stop her from messing with the world, and Shinya fell for him, not her, while Guren didn't seem to be that bothered with Shinya's flirting either.
- Last Het Romance: For a while, he tried to actually win Mahiru's heart and taunted Guren about the fact that it's Shinya himself who was her fiance. However, he gradually grew to dislike her very quickly and in the present time, he claims to feel tired of the opposite sex and seems to be happy just being near Guren.
- Living on Borrowed Time: As per the repercussions of being Back from the Dead, he can only be revived for ten years, having only two left, and if he knows the truth, he will crumble to dust.
- Mistaken for Gay: Guren and him went to a love hotel when they were 16 and a person said something about them being a couple.
- No Sense of Personal Space: With Guren.
- Panthera Awesome: His Black Demon Cursed Gear Byakkomaru (which translates as "White Tiger"), looks like a rifle. It's ability is demon manifestation (or tiger manifestation in this case). His Cursed Gear essentially unloads a streak of white tigers instead of normal bullets.
- Perpetual Smiler: Shinya usually has a smile on his face.
- Please Don't Leave Me: In the light novel Shinya is very dependent on Mahiru and desperately tries to win her over, even going so far as to consider suicide when she says she doesn't love him. After Mahiru's death he says that he considers Guren his reason for living, and has a breakdown in Chapter 47 when Guren confronts him after killing his comrades because he believes he has lost Guren to Mahiru's control.
- Prince Charming: Treated this way in First Shibuya by the other students, though his treatment at home was anything but.
- Stepford Smiler: It's been implied in the Catastrophe light novels that his smile developed as a defense mechanism that allowed him to survive when those that got angry or shut down didn't.
- Troll: Very much enjoys picking on Guren.
- Unable to Cry: He learned to shut down his emotions and stated in the light novel that he hasn't cried since he was five.
- Vitriolic Best Buds: With Guren.
- White Hair, Black Heart: Somewhat subverted. While he does have a darker side to him, he's mostly a good person, unlike his adoptive siblings and stepfather.
- Worth Living For: He said himself that Guren is his reason for living, and that he didn't have any reason to live before he met him.

A colonel of the Japanese Imperial Demon Army in the Seraph of the End: Vampire Reign manga series. She is the daughter of the noble Sangū family and the servant of the next head of the Hīragi family, Kureto Hīragi. She is Mitsuba's older sister.
She appears as a student at First Shibuya High in the Seraph of the End: Guren Ichinose: Catastrophe at Sixteen light novel series.
- Action Girl: As Kureto's servant, this is to be expected.
- Adaptation Dye-Job: Several different works in the series depict her with different eye colors. In the manga, they are purple like Mitsuba's; in the LN series and the manga based on it, they are blue; and in the anime, they are green.
- Aloof Big Sister: To Mitsuba.
- Blondes Are Evil: Out of all the blonde people in the series, she is the one that comes off as more unsympathetic.
- Bodyguarding a Badass: She is Kureto's servant.
- Bodyguard Crush: After Kureto kisses her, she admits that she's always had a crush on him.
- Foil: To Mahiru. Both are the older sisters of the two main heroines, and are extremely excellent and powerful. They additionally overshadow their younger siblings and have intimate feelings for black-haired males. However, unlike Mahiru who genuinely loves Shinoa, Aoi is rather indifferent and uncaring towards Mitsuba, to the degree that she was willing to sacrifice her in Nagoya.
- Combat Stilettos: Wears black heels as part of her uniform.
- Girlish Pigtails: When she was a teenager.
- Hair Decorations: Wears a blue ribbon in her side ponytail.
- She calls Mitsuba and her comrades traitors and that they don't deserve to live. When Yuu points out that Kureto was the one who betrayed them, killing some of their comrades and even some of his own soldiers, she scoffs at that.
- She also wonders if her sister slept with Yu and that is what made him join her group of traitors. This coming from a woman that follows Kureto, who betrayed and killed his own subordinates, mostly because she has a secret crush on him.
- My Master, Right or Wrong: She follows Kureto's every order without hesitation, no matter how gruesome it is.
- The Stoic: She hardly shows any emotion her face.
- Selective Obliviousness: Also told in Hypocrite above. She considers most of the main characters as traitors for standing against Kureto, their superior. This is while ignoring the obvious fact that Kureto's faction murdered their own comrades and committed a coup d'état against the Hiragi family, making both her and Kureto the actual traitors. Of course when Yu starts telling the truth she orders her soldiers to ready their arrows in order to silence him.
- Strong Family Resemblance: As a teenager, she looked like a taller and more buxom Mitsuba, especially with the pigtails.
