Voiced by Yumi Kakazu
Aya is a normal, everyday highschool student and loves spending her time in karaoke bars with her brother and friends. The day before her 16th birthday, she falls from an overpass and into a busy street, but gets rescued by a mixture of strange, bloody memories and a kind, strong man.
On her 16th birthday, she and Aki are shown a mummified hand that belonged to their family's ancestor, Ceres. Seeing it causes Ceres to awaken within Aya. She was supposed to be killed by her relatives, but Ceres' power killed them, and Aya fled.
Aya wants to return to being a normal student and tries to keep Ceres contained. As she comes to a mutual understanding with Ceres, she vows to take revenge on the Mikage clan.
- Angsty Surviving Twin: While Aki isn't dead, him being controlled by the Ancestor is treated as close to this as possible. In the finale, Aki's death ends up playing this straight.
- Break the Cutie: Gets shown a mummified hand that awakens an ancestral deity inside of her, sees her twinbrother suffer severe cuts and bleeds heavily next to her, and then her relatives try to kill her. All of that happens on her 16th birthday. And it's just the beginning!
- Bystander Syndrome: Early on, she understands that Ceres wants revenge on the Mikages and the Ancestor for stealing her heavenly robe, but doesn't think that she should be forced into the middle of it.
- Character Development: Matures from a typical, sassy teenager into a rather reluctant host for Ceres, before working alongside her and growing up into a young woman.
- Dangerous 16th Birthday: Ceres awoke inside of her on her 16th birthday.
- Disappeared Dad: Her father threw himself in front of her when her grandfather tried to have her shot.
- Hand on Womb: Does this when Suzumi asks about her period, and Aya realizes that it's very late, implying that she might be pregnant with Touya's child.
- Heroic BSoD:
- Volume 7 has her suffer one when Touya regains his memories as Touya Mizuki and completely forgets about her because of retrograde amnesia. She's mentally absent and mumbles quietly about having to 'call Touya' when Shuro and Yuuhi shake her out of it.
- Volume 9 hits her hard with Miori's suicide, which she did to purposefully drive a wedge between Aya and Touya. Aya only lies in her room and refuses to eat, citing that she should have died because her awakening as Ceres led to Miori's mother's death, and was Miori's reason for hating Aya.
- Volume 12 with Touya's death. She knew before Yuuhi and the others revealed it, and she's shown to be passive during Chidori's funeral. When she returns home, she breaks down crying.
- Impaled with Extreme Prejudice: Gets stabbed in the chest by the Ancestor. She managed to survive because she and Ceres fused with the Mana.
- Important Haircut: After Touya loses his memory of her, and a struggle between her and Yuuhi ends up with him accidentally cutting off one of her braids, Aya gets her hair cut to chinlength. It grows out over the series.
- Kid with the Leash: Sees herself as this to Ceres early on, trying to keep her contained as much as possible because of Ceres' wanton destruction of any Mikage when she appears. Loosens up over the course of the series, as the two come to understand each other.
- Leeroy Jenkins: Before becoming a couple with Touya, Aya has a habit of acting impulsively, like any teenager, which often lands her in trouble. When Touya becomes Aya's lover and Living Emotional Crutch, he has a way of getting her to think and act with a clearer head in a way no one else can. Without him, she is prone to revert to this. This trait is best shown during the Tango arc, while she is separated from Touya and still reeling from Miori's suicide. With Mikagi actively threatening Yuuhi and the lives of those close to her, she becomes prone to try handling matters entirely by herself and once again not thinking things through, including vowing never to work with Ceres again. This leads to her almost getting raped multiple times, being captured by Mikagi and her brain nearly being rewritten.
- Living Emotional Crutch: Serves this purpose to Touya over the course of the series. He's shown to be much more open with his emotions around her and tries to rein in his indiscriminate killing of enemies because it upsets her.
- Lotus-Eater Machine: Gets placed into one by Alec, which is described as being a happy dream for her, when they intend to place a microchip into her brain, to make her compliant. She manages to break out of it with Touya's and Ceres' help.
- Missing Mom: Her mother remains in a coma for the majority of the series.
- New Transfer Student: Changes school several times in the series, usually because there's a legend of a celestial maiden nearby, and her robe may still be around.
- Official Couple: Ends up with Touya.
- Ordinary Highschool Student: For the first chapter.
- Pregnant Badass: Volume 11 onward. She may be pregnant, and does her best to take care of herself and the baby, but she isn't above being as headstrong and feisty as she was before. However, she leaves Ceres to do the really physical things.
- Sex for Solace: Offers to fulfill Yuuhi's wish of having her when she's still too vulnerable from losing Touya. They don't go through with it, and Aya ends up ashamed for offering herself that way.
- Split Personality: With Ceres, though she's the reincarnation of her ancestor.
- Teen Pregnancy: Gets pregnant at age 17. The finale shows she's ready-to-burst on her 18th birthday.
- Tragic Keepsake: Aki's earrings, which she had originally intended to give him as his birthday gift. She keeps trying to give them to him, but she never manages, and keeps wearing them.
Ceres is a celestial maiden and one of the ancestors that resulted in the Mikage clan. Her past is akin to the Swan Maiden legend. She took off her celestial robe and set it aside to take a bath, when a man took and hid the robe. Asking him about it led to him denying knowing anything about it and, as she could not ascend back into the heavens without her robe, she remained on earth with him. Unfortunately, her version included the man raping and forcing her to bear his children.
Ceres gets reincarnated into the daughters of the Mikage clan every so often and her powers awaken inside of them on their 16th birthday. She wants to take revenge on the Mikages for what occured to her in the past, but the clan chose to kill their daughters, if they showed signs of having Ceres' powers.
When she gets reincarnated into Aya, her powers allow Aya to escape and surive.
Ceres tried to completely take over Aya's body, but she proved to be too strong and kept a tight grip on her for a while. As the series progresses, the two begin to talk and come to a mutual understanding, with Aya allowing Ceres free rein over her body, when the need arises.
- Ascend to a Higher Plane of Existence: What a celestial maiden does when reunited with her robe.
- Anti Heroine: She starts off as this, as she seems to apathetically kill countless people to have her revenge. As the series progresses, it becomes obvious that she anything but this trope.
- Broken Bird: Ceres turns out to be this. Contrary to the story she initially told, she was not forced into sleeping with Mikagi and bear his children, but willingly did so and they were happily married. Until she shared some of her powers with him, which caused him to become insane and jealous, to the point that he did rape her, and even killed one of their children. Then she killed her husband in rage and slowly died herself, saddened that her children would grow up without a mother and she wouldn't be able to watch over them.
- But Now I Must Go: In the grand finale, she leaves earth after everything is done.
- Character Title: Ayashi no Ceres and Ceres, Celestial Legend both refer to her.
- Does Not Like Men: She hates men because of her experiences as the legendary Swan Maiden. Averted, as the events of that legend didn't actually happen to her, but she retains a cold demeanor towards men for a long time.
- Emotionless Girl: She isn't human and doesn't understand the concept of emotions.
- Fusion Dance: She fuses with her Mana. Aya retains her own conscious during the process, too.
- Lady of Black Magic: Her powers are mostly psychic and they tend to have her look ethereal while using them.
- Ms. Fanservice: She not only lacks some human shame and doesn't mind showing more than some skin, until someone tells her to cover herself already, but clothes tend to appear sexier on her. That typical yukata Aya wears to bed shows quite some leg when Ceres appears.
- Mama Bear: Don't harm children. Especially hers. That's why she killed Mikagi, after all.
- Mana: This is what the celestial robe is actually called.
- Pre-Asskicking One-Liner: "Let me bestow joyful bliss upon you."
- Psychic Powers: Her abilities are along biopsychokinesis. She once explains that her powers are created by what your mind wants. If you want to cause pain, you can do so with mere thought.
- Race Against the Clock: She eventually gives Aya a deadline. If Aya cannot manage to stop the Mikages or return her celestial robe to Ceres, she will forcefully take over Aya's body and kill any Mikage. She does this because she realizes that Aya is pregnant and wants to finish things before the baby gets dragged into things.
- Rape as Drama: She was raped by Mikagi.
Aki is a typical highschool student, just like his sister. Just like Aya, he was shown the mummified hand and ended up reacting to it himself, getting numerous wounds on his body. This showed that he was the closest to the Mikage clan's ancestor, the man who wed Ceres and made her his.
When Aki realizes that he and Aya cannot be together until the issue with Ceres has been cleared, he tries to undergo experiments to recall his memories of the Ancestor, in hopes of finding out where her celestial robe is and allow her to leave. As the Ancestor's memories surface and mix with his own, Aki tries his best to remain himself.
- Brother–Sister Incest: As his memories become more muddled, he admits to seeing Aya as a woman and not his sister anymore. Unlike Mikagi, Aki is absolutely disgusted by it.
- Character Tic: Aki has a habit of pushing strands of hair out of his face with his right hand. Aya notes this as a typical thing for him to do and believes this means that her brother is back. Turns out that Mikagi merely played on that part.
- Corrupt the Cutie: Aki is a sweet guy, but when Mikagi's memories begin to pop up in him more and more, he slowly begins to become obsessed with his sister and hating men by her side.
- Dangerous 16th Birthday: He got the Ancestor's wounds inflicted on his body on his 16th birthday.
- Death Seeker: Downplayed. He's not actively seeking it, but he writes something on the inside of the envelope to his letter to Aya in this direction.Should I fail, please kill me with your hands.
- Determinator: Subverted. He tries his best to remain himself and not succumb to being pushed under by the Ancestor, but after seeing the entire mummy of Ceres, he is in such a shock that he realizes he can't stop Mikagi anymore.
- Dying as Yourself: In the finale, he manages to physically manifest enough to restrain Mikagi and say a farewell to Aya, apologizing for being such a disappointing brother.
- Good Scars, Evil Scars: Aki gets injured all over his body with the wounds the Ancestor died of, resulting in heavy scarring all over his body.
- Heroic Sacrifice: Restrains Mikagi, which allows Ceres to kill him.
- "I Know You Are in There Somewhere" Fight: Aya tries to pull this on him multiple times, though it is always unsuccessful. Aki is too much in the grip of Mikagi to get out.
- Split-Personality Takeover: He cannot contain the Ancestor for longer and gets taken over.
Touya is a man with no past, present or future. He lacks any memories of himself, beyond the name 'Touya' and 'Mikage'. With them being his only lead, he headed to the Mikage clan and offered his services to them in any way they needed, as long as they helped him regain his memories.
As a hired goon for the Mikages, he was initially tasked with finding and capturing Ceres, before this was expanded to capturing any celestial maiden he might encounter. After he admits to himself that he cares for Aya more than his memories, Touya escapes the Mikage facility and chooses to live on his own, and hopefully find out about himself in a different way.
- Amnesiac Hero: He has no memories of his past. All he knows is 'Touya' and assumes that to be his name.
- Artificial Human: It turns out that he is a human form evolved from Ceres' Mana over aeons.
- Back from the Dead: Touya gets killed and thrown into the ocean in Volume 11, only for him to reappear at the end of Volume 13, healthy and alive as can be.
- Badass Longcoat: He often wears one while working for the Mikages, but chooses to go for the suit version of the trope, once he decides to work on his own.
- Beware the Quiet Ones: He's quiet and unlikely to show emotions, but has no qualms over killing anyone just as qietly. Even as he begins to open up with his emotions, he's still got tricks up his sleeves.
- Face Death with Dignity
- While the Ancestor keeps shooting Touya over and over, he remains calm and asks him about the going-ons at the Mikage's lab and their plans. Even with a gun placed directly on his forehead, Touya doesn't flinch and merely mutters Aya's name one last time.
- In the finale, Touya knows that he will die within a decade or less. He's at peace with the idea and asks Yuuhi to look after Aya and their child, once he's gone.
- Fake Memories: Touya regains his memories and reveals himself to be Touya Mizuki, a descendant of the Mizuki and Mikage celestial maiden. It turns out to be all faked, as these are memories implanted into him by the Mikages in order to use him as a tool.
- Forgotten First Meeting: Aya met him when she was around eight years old, when she visited the island that Touya was on for a vacation. Due to it being a vague childhood memory and Touya's amnesia, they both forgot until they returned to the island to jog their memories.
- Healing Factor: Touya's wounds heal incredibly fast. Even a broken arm takes a day or two to heal, when it should take weeks or months. Justified, as he is part of the Mana and that can heal itself as necessary. He loses that ability when he returns the Mana to Ceres.
- Laser-Guided Amnesia: A car accident resulted in him losing his memory.
- Living Emotional Crutch: Since becoming a couple with Aya, he has become the rock in her increasingly perilous life. Particularly, he has had the most success in getting her to tone down her impulsiveness, to remember how to not relentlessly blame herself, and most importantly, bring her out of a serious Heroic BSoD.
- Mr. Fanservice: Touya is the source of majority of the fanservice in the series.
- Meaningful Name: Touya means 'Ten Nights'. This is in reference to how an old man found him as an infant and he grew into a fully grown man within ten nights.
- Nothing Up My Sleeve: Despite a body-check, he still manages to sneak in his trusty dagger. Justified, as the dagger is not up his sleeve. He can suck it into his body, when needed.
- #1 Dime: A seashell that a young Aya gave him years ago. However, it broke when he got hit by a car.
- Official Couple: With Aya for most of the series.
- Our Homunculi Are Different: Less alchemy and more organic technology.
- Psychic Link: When he leaves his dagger with Aya, he can feel her emotions at times. Like when she is in danger, he notes that he can feel her heartbeat increasing.
- Rescue Romance: He met Aya by saving her from being run over by a car.
- "Shut Up" Kiss: While Aya is ranting, he kisses her to keep her quiet.
- The Stoic: Touya rarely ever shows emotions, unless he's around Aya.
- Wandering the Earth: After the revelation that his identity as Touya Mizuki was fake, Touya chooses to wander around Japan and try to find a clue about who he is.
- Winged Humanoid: Touya appears at the end of Volume 13 with wings on his back.
- Younger Than He Looks: While he looks to be in his twenties, Touya is actually about 9 or 10 years old.
- Your Days Are Numbered: As he no longer is part of the Mana, he is doomed to die within a decade.
Yuuhi is a highschooler, just like Aya and Aki. He lives with his sister-in-law and Kyuu in a large mansion, away from the main Aogiri estate. He is the mainchef of the household and is a superb cook, dreaming of one day opening a restaurant and running it with his wife.
Suzumi sent Yuuhi to the Mikage estate, in order to have him rescue Aya and bring her to them. While she offers not only a home to Aya, she also tells Yuuhi to become her bodyguard and even gives him wristbands and a headband imbued with her own celestial maiden powers.
- Accidental Pervert
- The first night Aya spends at the Aogiris, Yuuhi accidentally walks in on her drying off after a bath. She promptly beats him for it.
- He gets hit by something and is propelled forward, landing facefirst against Aya's chest, with one hand on her breast. Again, she slaps him for it.
- Badass Normal: He's an adequate fighter.
- Dude, She's Like in a Coma: He tried to kiss a sleeping Aya, but she slapped him in her sleep when turning over.
- Empowered Badass Normal: Thanks to the wristbands and headband Suzumi made for him, his strength is amplified, and he has a certain amount of defense against attacks, whether they be natural or celestial power-based.
- Handicapped Badass: Subverted. When Yuuhi's arm gets broken by the Ancestor, he tries to keep up with him and Aya, but just plain can't. And he's ashamed about it.
- Improbable Weapon User: Yuuhi's weapon of choice are cooking chopsticks!
- I Want My Beloved to Be Happy: It takes him quite some time to come to terms that his crush on Aya won't go anywhere, but midway through the series he becomes more open about supporting Aya and Touya's relationship.
- Ordinary High-School Student: He remains one, unlike Aya and Aki, despite the wristband-induced power-up.
- Real Men Cook: After his mother left the family, he didn't like whatever food was presented to him and he started to cook for himself. He found a passion in it and has improved his skills ever since.
- Romantic Runner-Up: There's no reason why Aya wouldn't fall for him and it is implied that she loves him in another way, but nothing really comes of it. Until the finale, where Touya asks Yuuhi to look after her and their baby, once he dies.
- Supreme Chef: His cooking gets complimented multiple times.
- The Unfavorite: The Aogiri clan made it clear they did not like him. And the only ones that ever showed kindness to him were his older brother, Kazuma, and his sister-in-law, Suzumi. It turns out that his father loves him, too, but can't show it too much because of a status to uphold.
- Wholesome Crossdresser: He has to dress up as a girl for an arc because the school they are investigating is an all-girls school. Yuuhi isn't considered beautiful, though he does gain the attention of one girl, who thinks his body is well-trained.
The ancestor of the Mikage clan, whose name originates from his name: Mikagi. He found a bathing Ceres and managed to get her to become his wife and bear his children. In the end, he suffered dozens of severe injuries on his body and died from bloodloss. When Aki saw Ceres' mummified hand, Mikagi revealed himself inside of him and Aki suffered the same wounds, yet survived.
Mikagi ends up taking over Aki's body for a good portion of the series, as Aki cannot manage to contain him indefinitely. He is obsessed with being reunited with his wife and doesn't care that her current vessel is his current vessel's fraternal twin. Mikagi alone knows where Ceres' celestial robe is and, unlike the man in the Swan Maiden legend, was very careful to never even let his children know of its location.
- Attempted Rape: Tried to rape Aya, but some power that came from Touya's dagger, which Aya was carrying in her bra, repelled him. Mikagi left, furious that Touya was still around.
- Big Bad: The main antagonist, whose actions caused the tragedy of Ceres and her search for her Mana.
- Brother–Sister Incest: He tried to sleep with Aya, as she was his wife's vessel, and didn't care about blood relations.
- Crazy Jealous Guy: He hates any man who may look at Ceres and considers her to still be his wife, regardless of what body they may have been reincarnated in. His jealousy was so bad that he even considers his own children were trying to take his wife from him.
- Death Equals Redemption: His true nature is revealed as he and Ceres talk in what seems to be an afterlife.
- Domestic Abuse: Mikagi turned into this, unfortunately. He beat his wife when she asked him about the location of her Mana, raped her, and also had no qualms about hitting his children.
- Drunk with Power: He becomes amazed at what just a fraction of Ceres' power allows him to do.
- Facial Markings: He gains several when he gets his original form back in the finale.
- Fusion Dance: Mikagi fuses with the artificially created Mana. It allows him to regain his original form and gives him powers akin to a celestial maiden, along with its healing capabilities.
- Good Scars, Evil Scars: While possessing Aki's body, the scars of his old injuries remain. If Mikagi's hold on him slips and Aki gets a brief glimpse, the scars disappear. The scars are also gone when Mikagi regains his original form.
- Hero Killer: He is the one to shoot the fatal bullet into Touya's brain.
- Kubrick Stare: Sports several while possessing Aki.
- Longhaired Pretty Boy: He's quite attractive and his hair reaches past his shoulderblades.
- Love Makes You Crazy: Mikagi comes across as very stoic, unless his wife comes into play. He will do what he wants, when he wants, and nobody can tell him otherwise. Even his emotions are much more apparent when Ceres is nearby.
- Love Makes You Evil: His reason for killing his children, as well as anyone else that comes between him and his wife, is because of his fear that someone will break them up.
- Mad Love: It's quite clear that Ceres despises Mikagi for his raping and forcing her to be his wife, but Mikagi doesn't care. He insists that she loves him and claims that she gave him part of her power as a proof of that. It turns out that he's right. Ceres does still love him, but he had changed so much that she was grieving for how he was originally.
- Nice Guy: He started off as one. Mikagi was an upstanding member of his tribe and saved Ceres from a shark. And it's implied that he was the only man Ceres ever encountered to fall in love with Ceres and didn't just want her body.
- Offing the Offspring: Killed one of his children that stood between him and his wife.
- Split-Personality Takeover: He takes over Aki's body for most of the series.
- Stalker with a Crush: He always follows Ceres because he's deeply in love with her.
- Start of Darkness: Ceres reveals her past with Mikagi to Aya, allowing her to see how the two of them got together, and how getting defeated by some men made him feel worthless next to her. This lead to her giving a fraction of her power to Mikagi, which eventually lead to their downfall.
- Took a Level in Jerkass: Mikagi used to be a gentle, kind man, but a mixture of jealousy, insecurity and obtaining some of Ceres' power caused him to become mean-spirited, quick to anger and terrifying.
- Was It All a Lie?: When Ceres claims that she never actually loved him, but merely used him to produce offspring, just as she had with a lot of men previously, Mikagi doesn't say anything, but his expression makes it clear that he wonders this. And he is not happy about it.
- With Great Power Comes Great Insanity: The piece of power Ceres shared with Mikagi amazed him, at first, but he quickly began to go insane with just how much he could do with it.
Kagami is a cousin to Aya and Aki. He seems to be the right-hand man of his grandfather, who is the head of the Mikage family, but is quickly revealed to have a different goal in mind. He tells Touya to not kill Aya, but instead capture her, so he can learn more about her mysterious powers.
Kagami eventually calls the Celestial Project into life. He hands out medicine created from the strange cells found in Ceres' blood sample, to awaken the celestial powers in any maiden's descendants. Once he obtains the entire mummified corpse of Ceres, he manages to mass-produce the medicine and puts it into Japan's water supply, and gets descendants from all over Japan to awaken.
- Abusive Parents: His mother beat him if he didn't get perfect grades. Her obsession with him being 'perfect' likely springs from him being an illegitimate child, and wanting him to prove to be 'worthy' of the name Mikage.
- Armor-Piercing Question: He's on the receiving end of one from Alec near the finale.I don't want to become demon... or God. I only human! You're only human, too, right?!
- Arranged Marriage: He is in an arranged engagement with a woman, but has absolutely no feelings for her.
- Bastard Bastard: He admits to Alec that he is the product of his mother having an affair shortly before marrying into the Mikage family, meaning he has no blood-relation to them.
- The Dragon: Come across as this to grandfather Mikage.
- Dragon with an Agenda: Unlike his grandfather, Kagami wants Aya to stay alive. Once the grandfather is killed by the Ancestor, Kagami has nobody standing in his way of creating the C-Project.
- Going Down with the Ship: During the finale, he chooses to remain on the sinking ship after handing Alec the remaining celestial maidens' fertilized eggs and documentation of the Mikage family's dirty dealings.
- My God, What Have I Done?: He realizes what his plans have caused when Aki not only gets taken over by the Ancestor, but ultimately ends up dying.
- Pet the Dog: Kagami does love his mentally-unstable mother. It's implied that his obsession with the celestial maidens stems from good childhood memories, where his then-sane mother told the legends to him.
- Stoic Spectacles: He rarely shows emotions behind his glasses. Strangely enough, whenever he appears without glasses or an ironed suit, Kagami's emotions are much easier to read.
- Utopia Justifies the Means: His plan will lead to a better world for humanity, even if it's on a path lined with corpses.
- Visionary Villain: He believes that the C-Project will save the world and humanity.
- Well-Intentioned Extremist: He knows that forcing the celestial powers in any descendant can backfire horribly, with many of those descendants either dying before the powers manifest or shortly after, and that he is condemning many people to death. But he thinks that humanity will end up destroying itself, so he wants to have as many celestial maidens around as possible, so they can produce stronger offspring with chosen partners, and create a new era of more intelligent and healthier humans.
Alexander O. Howell
Alexander has a multitude of duties. He was the scientist in charge of helping Aki regain his memories as the Ancestor, and gave Touya the various memory discs that allowed him to infiltrate schools and hospitals as a doctor on his search for celestial maidens. He's generally referred to as Alec.
- Anti-Villain: Alec believes that Kagami's plan has some merit, but often feels torn because he also considers that Kagami's ways are wrong.
- Break the Cutie: The results of Kagami's plans keep horrifying Alec, with Aki getting taken over by the Ancestor being the smallest of things. After Alec witnesses the artificial Mana revert the Ancestor to his original form, Kagami finds him cowering in a corner of the lab.
- Faked Kidnapping: When Touya rescues Aya from the laboratory, Alec pretends that Touya is holding a gun to his back and taking him hostage. It works, and allows the two of them to escape safely.
- Occidental Otaku: Alec's love for anime and manga had him learn Japanese by playing videogames, which is the reason why his Japanese is a tad broken. He even mentions that his preferred type of woman is Shiori from TokiMemo.
- Only Known by Their Nickname: Shortly after his introduction, his full name is rarely mentioned.
- Scotland: Originally hails from there.
- The Smart Guy: His IQ is listed to be 260!

- Eagleland: She comes from America.
- Generic Girl: Beyond her role, and belief in Kagami's plan, she doesn't get much screentime.

- Taking the Bullet: Took on the Ancestor's attack when he had meant to harm Ceres.
Wei Fei-Li
Wei is hired to be Aki's bodyguard alongside Touya, though both assumed they were the only one. He's also a professional assassin. After Touya goes rogue, Wei feels a personal vendetta against him and wants to personally kill him.

Rurik is responsible for the bio-science department of the C-Project.
He also aids Alec and seems to be good friends with him.
- Generic Guy: Very little is known about him.
- The Lost Lenore: It's mentioned that his sickly wife died. His cooperation with the C-Project stems from wanting humans to become stronger, so nobody would lose their loved ones because of frail constitution.
Assam
Assam is a child soldier, hired for the C-Project after Touya went rogue. He's supposed to look for awoken celestial maidens, but doesn't care much for that. He becomes obsessed with causing pain to Touya, after he injured his leg.
- Badass Adorable: Assam loves to eat his ice cream when on break, and get a new one after smashing it into his subordinate's face, but he is a trained soldier and doesn't hesitate to kill.
- Child Soldier: He was one in his home country. During the finale, Kagami tells Assam that he no longer has to do this and might even go to school like a normal child.
- Suspiciously Similar Substitute: For Touya, after he goes rogue.
Suzumi Aogiri
Suzumi sensed Aya's powers as a celestial maiden and sent Yuuhi out to get her, trying to keep her safe from the Mikage family. She is the descendant of a celestial maiden herself, though she has kept this a secret from most people. She planned to run a school teaching traditional dance with her husband and runs it on her own, after Kazuma died.
- Broken Bird: Suzumi lost her husband to a car accident, and the shock and grief caused her to have a miscarriage, too. Had Yuuhi not stopped and given her a new purpose in life, she would have killed herself.
- Cool Big Sis: For Yuuhi, though she also takes on this role for Aya, despite no relation.
- Interrupted Suicide: Yuuhi walked in on her trying to cut her throat after her husband's funeral.
- Lotus-Eater Machine: Suzumi gets put under the influence of a machine that brings her back to her past, when Kazuma was still alive and they were expecting a baby. She chooses to remain inside, but Yuuhi manages to get her out of it.
- Parental Substitute: To Yuuhi, as well as to Aya.
- Psychic Powers: Telekinesis, which she initially demonstrates by opening and waving a fan through mere thought.
- Stepford Smiler: Downplayed. Suzumi comes across as strong, but when she gets confronted with her dead husband and lost child, she succumbs to her emotions. She even admits to Aya that she isn't strong at all.
- Yamato Nadeshiko: She embodies this trope with her gentle, yet fierce personality.
Chidori Kuruma
Chidori found Aya and Yuuhi, based on a picture she took of them, although Ceres was in possession of Aya's body at the time. She begs them to come to the hospital with them, so they can encourage her little brother to regain hope about his injured legs again. She turns out to be a celestial maiden, whose appearance changes drastically when her powers are in use. She moves in with the Aogiris and helps the search for a celestial robe.
- Clothing Damage: A common side-effect when she transforms into her celestial form.
- Cool Big Sis: Shouta sees her as one.

- Girlish Pigtails: Her hair is usually put into two pigtails.
