Runaway Spirit Squad
Elsea de Lute Irma
Haqua du Lot Herminium
Nora Floriann Leoria
- Anti-Hero: Despite her questionable methods she seems to have good intentions. She has little regards for the rules and is perfectly okay with killing or cheating in order to do what she thinks is the right thing.
- Aren't You Going to Ravish Me?: At first she's understandably creeped out when Keima says he wants to grope her and begins chasing her, but then she gets legitimately pissed when she finds out it was just an act to bait the spy Fiore.
- Blue Blood: Her horns signify that she is descended from an important family and are a mark of great prestige. This is something she is VERY proud of.
- Cute Monster Girl: She has one horn.
- Dark-Skinned Blonde: White-haired variation.
- Double Agent: She joins Vintage and mocks Haqua about it, only to get Keima out of a dire situation regarding Vintage. The whole time she claims that she's going to side with the group more likely to win, but still stays more consistently in the good guy camp.
- Fantastic Racism: She only refrains from killing humans when it would be particularly convenient if a devil would also be caught up in it.
- Horned Humanoid: Has one horn on the right side of her head.
- I Was Just Passing Through: "It's not like I'm your ally now. I just can't stand Vintage doing as they please in my district!!"
- Jerk with a Heart of Gold: Although she claims to be playing both sides of the conflict with Vintage, she has been surprisingly very helpful to Keima and has not shown one sign of genuinely defecting to the other side even when Keima was in trouble.
- Knight Templar: She's willing to kill or break the rules to get Runaway Spirits out. Compounding the issue is the fact that she's fairly reckless and impulsive.
- Lovable Alpha Bitch: As bitchy and superior as she can be, she's also shown herself to be more thoughtful than she lets on, and has occasionally gone out of her way to help others despite her self-serving facade. And she indirectly saves Keima's life by sending Ryou to activate the goddess sensor's roll-call feature when she figures that Vintage will be looking into the disappearance of one of their agents.
- Mind Probe: Her senior demon powers let her delve into people's hearts. It backfired hard when she used it on Keima.
- Murder Is the Best Solution: If her target's been hurt by someone, she'll give them revenge up to and including killing the one who hurt them.
- Obfuscating Stupidity: Plays dumb while pretending to abandon Haqua and Kanon out of self-interest, but uses it as an opportunity to confirm whether or not Fiore is actually The Mole for Vintage.
- Pet the Dog: Although her regard for human life is low, she's very hesitant to do anything that could lead to a fellow New Hell Devil dying. Twice now, when it is pointed out her actions may result in Elsie's death, she reconsiders her actions. Unless she's angry.
- Really 700 Years Old: Ten years older than Elsie and Haqua, who are about three hundred years old.
- Wall of Weapons: Had a whole pile laid out on the ground when she wanted to kill Keima.
- What the Hell, Hero?: Goes and tells Shalya that she knows exactly how Shalya betrayed Haqua and the suffering Haqua is going to go through because of her. Nora being Nora, she rubs it in quite a bit.
- White Hair, Black Heart: She's an Anti-Hero with questionable methods.
- Who Wears Short Shorts?: Her outfit is basically low rise shorts over what appears to be a leotard.
- Wild Card: She claims to be playing both sides at once due to being unsure for how things will work out. Either way she can count herself a winner. For example, Haqua gets herself locked up, so she joins Vintage, but then she sends Ryou to save Keima. In the end, it's clear she's on the protagonist's side.
- Zettai Ryouiki: Grade A with her shorts.
Shalya Frey Amon
A friend of Haqua, she was the former District Chief of Area 30-2 and Elsie's former superior. She was reassigned to be the District Chief of Area 30-4.

- Gender-Blender Name / Named After Somebody Famous / Religious and Mythological Theme Naming: Her name comes from traditionally male figures from different religions.
- Really 700 Years Old: She's about three hundred years old, like Elsie and Haqua.
- The Stool Pigeon: Of the Betrayer Belinda variety. Tells the public safety department that Haqua has been leaving her post a lot lately so that Vintage can have an excuse to replace Haqua with one of their agents as opposed to herself. The information she was selling appears to have been more valuable than she expected, however, leading Haqua to not only be stripped of her position but also to be arrested for treason.
- It is later reveled that she was working with Rimyuel on Chief Dorkuro's plan to expose and stop Vintage, Satyr and other anti-Hell members.
Cresta and Camry
- Bare Your Midriff: Camry
- Blue Blood: As indicated by their horns.
- Horned Humanoid: They both have two horns.
- Meaningful Name: Cresta's name means "crest" in Spanish while Camry is the phonetic of "kanmuri" which means "crown" in Japanese.
- Those Two Girls: They always appear together as Nora's lackeys. They get offended when it turns out that nobody in the main cast actually knows their names.
- Vehicular Theme Naming: They share their names with two models of Toyota cars. Cresta is also a name for a Vauxhall car model.
Rimyuel (Akari Kurakawa)
Voiced by: Kujira (JP), Sam Roman (season 2), Mark X. Laskowski (Goddesses) (EN)She is the Hell counter-measures branch Chief who sent Keima the contract email. She was a hero during the Almagemachina, the war that sealed the Old Devils 300 years before the start of the series.
- Big Good: She was one of the greatest heroes of the war that created New Hell and she is in charge of the Runaway Spirit Squad. The current plan to save the world was of her own making, and her Alternate Self was created to end the conflict with Old Hell entirely.
- Da Chief: The chief of the Runaway Spirit Squad.
- Dem Bones: Her body after the Almagimachina.
- Double Agent: She is obligated to work with Vintage, but helps Haqua escape and tells her neither good nor evil will win the coming war. They need strength.
- Fan Disservice: Keima and Dokuro's other self accidentally contact her when she is naked and in the middle of changing. She acts embarrassed, but since she is currently a miniature skeleton, there isn't much to look at.
- Haunted Technology: She is basically a demon ghost controlling a robotic body.
- Inconvenient Summons: Keima and Dokuro's other self happen to contact her when she is in the middle of changing clothes.
- I Was Quite a Looker: Claims this, the flashback showed her as a skeleton with normal proportions. Depends on your taste. But if you count her other self that accompanies Keima, which grows to become the smoking hot Yuri Nikaido, as her past form, then yep. She was indeed a looker.
- Killed Off for Real: This incarnation of her is assassinated by New Hell's corrupt police force on the orders of Satyr, though a human Reincarnation continues to live.
- The Man Behind the Man: Allegedly was the leader of Vintage. Haqua doesn't believe it.
- Miniature Senior Citizens: Actually an artificial body.
- Punch-Clock Villain: Works for Vintage more for political reasons than out of any actual loyalty to their cause.
- The Scapegoat: Touted by the Directors as the leader of Vintage, she was removed from her position and apparently executed.
- Wild Card: Appears to feel that something needs to be done to help New Hell, but doesn't entirely approve of what Vintage is doing. Thus, in the space of just a few short chapters she first strips Haqua of command and brands her a criminal, then lets her escape. If Haqua can find a better solution to the problems New Hell is facing, well, so much the better.
The rulers of New Hell.
- Ancient Conspiracy: At least four of them are part of Satyr, a secret society made of select few Devils from distinguished families that have been around since Old Hell.

As a result, Elsie uses Divine Intervention to prevent Lune from causing a Time Crash, allowing Dokuro's plan to pull through and sabotage their own plans.
- Karma Houdini: At the end of the Manga, Satyr's plans are foiled, but they are able to use one of their own as The Scapegoat, enabling the rest of them to get away scot free.
- The Man Behind the Man: Some of the directors are the actual leaders of Vintage.
- No Name Given: There's a total of ten directors yet we only know the names of four of them; these being Gare of North America, Gorogoro of Central Africa, Roudret of Europe and Anoa of Antarctica.
- The Omniscient Council of Vagueness: They're always portrayed as nothing more then tablets and we know nothing even remotely about them other than the fact that at least four of them are part of Satyr and are trying to resurrect old Hell.
- Powers That Be: They are the mysterious rulers of New Hell.
- Running Both Sides: They run the Runaway Spirit Squad and at least four of them run Vintage as well. The Runaway Spirit Squad is part of a scheme to confine the Jupiter Sisters. They originally planned to capture the goddesses as soon as they finished annihilating their puppets in Vintage.
Fiore Loderia Lavigneri
A traitorous New Devil who resents the changes to Devil society and wishes to bring back Old Hell. Works for an organization called Vintage. A former classmate of Elsea and Haqua's.
- Adapted Out: In the third anime season, her role of stabbing Kanon/Apollo is covered by Lune in episode one, and her attack on Keima's house, with Fiore ending up imprisoned in a lost spirit bottle, was skipped over as of episode four. In the end, all of her Goddess arc appearances were cut from the adaptation.
- Always Second Best: To Haqua.
- Blue Blood: The horn on her head shows that she's from a noble family.

- Evil Is Petty: After overpowering Nora and Haqua, replacing them with hagoromo-made doppelgangers, she immediately starts gloating and re-names the doubles "Just-Tits" and "Pencil", respectively.
- Floral Theme Naming: "Fiore" means "flower" in Italian.
- Horned Humanoid: Has one horn on the right side of her head.
- I Just Want to Be Badass: Part of the reason why she wants to kill a goddess is so she can be accepted by the higher-ups of her group.
- Ineffectual Sympathetic Villain: Not taken seriously by Keima at all. After being captured she's been spending her time whining about how she wants something to eat.
- In the Hood: Wore one during the time she spied on Kanon.
- Knight of Cerebus: She's responsible for the giant, nasty incident involving Hinoki and most of the other problems that start going wrong from the Yui arc onwards.

- Cape Snag: Attempts this on Haqua's new cape, forcing her to discard it.
- Combat Sadomasochist: Between her frenzied stabbing, gasps of pleasure at getting cut, and insane laughter, this becomes extremely evident during her battle with Haqua.
- Composite Character: In the anime, she replaces Fiore as Kanon/Apollo's assassin.
- Dark Action Girl: She's quite brutal and ruthless, as seen during her battle with Haqua.
- Hard Head: She received no less than eight blows to the back of her head with a metal pole. The fact that she went on to have a very nasty fight with Dokurou right after that makes her resilience stand out even more.

- Horned Humanoid: She has two short horns on the sides of her head.
- Impaled with Extreme Prejudice: Via the top spike of the orb switch table inside the Akanemaru, right after Dokurou disabled the room's magic barrier. She's still breathing though.

- Why Don't You Just Shoot Him?: Lune has no idea why they should take potential threats like the goddesses captive instead of just killing them.
- You Gotta Have Blue Hair: Has green hair.
- You Will Be Spared: Comes close to defeating Haqua, but chooses not to finish the battle due to other concerns and the fact that she considers Haqua a Worthy Opponent.
Voiced by: Harumi Sakurai (JP), Allison Sumrall (EN)A member of Vintage that helped Lune search for the Goddesses.She reappears in the third memory fragment of the Heart of Jupiter arc as the Vintage member tasked to force Runaway Spirits into the female students of Maijima East Elementary School.

The Jupiter Sisters
Jupiter Sisters as a group
Centuries ago, the Jupiter Sisters, goddesses from Heaven, managed to seal away the Runaway Spirits by making a collective Heroic Sacrifice, trapping themselves alongside their prisoners. When the spirits finally managed to escape, the sisters were released as well. They ended up in the spirits' human hosts, resting dormant until they could regain their strength. Unlike the spirits, however, the goddesses draw strength from love and affection.
Collectively, they share the following tropes:
Collectively, they share the following tropes:
- Barrier Maidens: They were this when they made their Heroic Sacrifice to seal away the Weiss 300 years before the story. That is until the Great Runaway Spirit Escape 10 years before the story.
- Chekhov's Gunman: Five of the goddesses are inside Keima's previous capture targets.
- Famous Ancestor: Jupiter, king of the Roman gods, from whom the sisters take their collective name.
- Gender-Blender Name: 4 of the 6 goddesses are named after male gods from the Roman pantheon.
- Level-Up at Intimacy 5: The more affection the hosts have, the more power the goddesses can unleash. Their rough progression: The Mirror Shows Your True Self -> Willing Channeler -> Holy Halo -> Power Gives You Wings.
- The Mirror Shows Your True Self: Once they've regained enough strength, the goddesses can appear in their hosts' reflections and shadows.
- Our Gods Are Different: What the sisters were capable of at full power is unclear, but they weren't omnipotent. As they regain their strength, they become able to switch places with their hosts, manifesting Super Strength and Super Speed, and have a measure of resistance to spells.
- The Power of Friendship: Much of the Jupiter Sisters' power is derived from the bond they share. If they lose even one of their number, they must all be replaced with a new set of Jupiter Sisters immediately.
- The Power of Love: Weiss feed on misery while goddesses grow with love.
- Religious and Mythological Theme Naming: Each named for one of their relatives in the Roman pantheon.
- Screw the Rules, I'm Doing What's Right!: When they send Keima's mind back to when he was a child ten years in the past, they acknowledge they are screwing with time and the laws of Cause and Effect, but it is a necessary action for Keima to save them all.
- Sealed Inside a Person-Shaped Can: The sisters were originally sealed alongside the Weiss, but due to something breaking the seal most of them unconsciously gravitated towards a young girl. Not intentional, but the same end result.
- Sharing a Body: The goddesses share a body with their hosts and either person can grab control at any time. However, seeing as the goddesses are decent people and are hitchhiking, they rarely do so when it's not important.
- Shipper on Deck: Each goddess supports Keima's relationship with her respective host. However, they are not happy about the fact he is technically six timing their hosts.
- Sibling Triangle: Of sorts. Because the goddesses' power comes from love, all six of them have a vested interest in making sure Keima remains true to their host. And that's not counting the feelings of the goddesses themselves.
- Split-Personality Makeover: When the goddesses are in control of their hosts' bodies, their hair or other features change to indicate it.
- Symbiotic Possession: All the goddesses are shown to get along with their hosts pretty well. The hosts are at best good friends with them and at worst bemused but generally accepting of the Goddesses.
Voiced by: Kaori Nazuka (JP), Juliet Simmons (EN)After a certain incident with Keima 10 years ago, Tenri became possessed by Diana, the first Jupiter Sister seen in the series. Compared to Tenri, Diana is assertive and strong-willed, and is able to temporarily take full control of Tenri's body at times.She is the third oldest of the Jupiter Sisters.
- Clingy Jealous Girl: She tends to get very aggressive when Keima pursues or shows interest in anyone not named Tenri.
- Cool Big Sis: Diana acts like this for Tenri.
- Good Is Not Nice: Diana can be rather cold and inconsiderate some of the time.
- Inconvenient Attraction: Diana eventually realizes she has fallen in love with Keima, something that she finds horrible since she's supposed to be encouraging Tenri's love for him and she doesn't want to be in love with a "scum" like Keima.
- Inferiority Superiority Complex: Beneath Diana's not-inconsiderable ego, she believes she's caused trouble for Tenri, herself, and her sisters.
- I Want My Beloved to Be Happy: Diana finally admits she loves Keima. But she would rather have him love Tenri more, and feels guilty about even being in love with Keima to begin with.
- Lightning Bruiser: She's supposed to be the strategist of the group, but is able to grant Tenri superstrength and superspeed.
- Matchmaker Crush: She tries to push Tenri towards Keima, but since Tenri is so shy Diana ends up interacting with Keima so much that she falls in love with him.
- Mundane Object Amazement: Diana is really impressed with Tenri's magic tricks even though she herself used to split the sea and control the weather.
- Psychosomatic Superpower Outage: Diana comes to the conclusion that the reason her wings haven't appeared yet even though they should have grown by that point is that her guilt over having developed a Matchmaker Crush on Keima is getting in the way. Tenri somehow manages to bring out Diana's wings later.
- Sacred First Kiss: She isn't happy about the fact that Keima took her first kiss when he kissed Tenri.Diana: A kiss is something... that is done only with the person you spend the rest of your life with. I'll make you take responsibility for it!
- The Smart Girl: She was the tactician of the six sisters, though not necessarily the most intelligent.
- Sugar and Ice Personality: At first, she was much more cool-headed and aloof, but very caring towards Tenri. After she starts developing feelings for Keima on her own, she starts to act more Tsundere.
- Super Speed: Even when Tenri was a little girl and Diana didn't have much power, she was capable of lifting Keima and sprinting so quickly that she got away from all the Runaway Spirits under the town in moments.
- Super Strength: She can block Nora's full force giant mace attacks, though not easily. Presumably she'd be able to do better than this now that more of her power has been restored.
- Tsundere: She clearly has no interest in Keima herself and is only trying to help Tenri. Pay no attention to her blushing and fretting over Keima taking her first kiss when he kissed Tenri.
- Tsurime Eyes: Her sharp eyes contrast Tenri's Tareme Eyes.
- You Never Did That for Me: Diana's complaint to Keima asking if he exchanged some S-P-E-C-I-A-L kind of love with Vulcanus and Tsukiyo.
CLICK HERE TO SEE APOLLO'S FORM
- Antiquated Linguistics: Speaks in ancient Japanese.
- Chekhov's Gun: Keima looks back and remembers Kanon trying to contact him during tests. However, there's actually an even earlier hint that she still has her memories: The omake chapters of her host.
- Cheshire Cat Grin: Sported one of these during the Team Shot in FLAG 265.
- The Ditz: Apollo cheerfully owns up to being an idiot. Muses aren't supposed to be good at thinking, apparently.
- Facial Markings: She has arrow-like markings under her eyes, a mark in the middle of her forehead, and eyeliner.
- Magic Music: When she sang, she could change the landscape. Kanon is horrified at this and clearly never, ever wishes to sing with her.
- The Medic: Apollo's an expert in the healing arts, according to Diana and Vulcanus. Which is a bit of a problem when she's the one in a coma.
- Moving the Goalposts: Possibly justified depending on how you look at it. She was stabbed by Fiore and cursed. They judge the curse will take about a week to kill her unless they can remove the knife (apparently just having a dagger in your intestines for a week is okay) and get to work. When they finally do, it turns out that she's still not going to wake up because she changed the form of her body to make the curse take longer to affect her. So she's still in a coma and Keima has to go look for Mercurius now as well because she knows lots of weird spells and might be able to remove it. Eventually subverted in that Apollo is aware of what's going on, but is choosing not to wake up so she can continue to stave off a disaster she sees coming in the future. This means that finding Mercurius is actually unnecessary to helping her.
- Wife Husbandry: Vulcanus warns the other goddesses that Keima's past and present mind have been swapped, and they must be careful with the younger Keima lest they accidentally affect the present Keima, preferably keeping him asleep. Apollo however takes this as a suggestion and tries to imprint the young Keima's mind on Kanon.
CLICK HERE TO SEE VULCANUS' FORM
- Berserk Button: Vulcanus will not tolerate *any* threats to Tsukiyo's purity.
- Call-Back: Vulcanus insists that Keima carry her around, similar to the time he had to carry Tsukiyo around during her capture arc.

- Curtains Match the Window: While in possession of Tsukiyo, she turns her host's eyes and hair rose pink.
- Declaration of Protection: She has sworn to protect her host.
- Disability Superpower: She may be blind, deaf, and immobile, but her powers more then make up for it by using Luna as her eyes and ears... and everything else as her fists.
- Eyes Always Shut: She's not entirely blind, but that's how she's drawn.
- Fiery Redhead: While Vulcanus possesses an aura of a noblewoman, she can be very fiery when she is protecting her host or finds Keima being unfaithful.
- Foil: Vulcanus is expressive about her feelings whilst Tsukiyo remains stoic. Both still retain an aura of a noblewoman.
- Foreshadowing: If you look at the image of Tsukiyo, you can see Luna already standing up and holding onto the sofa. The omake pages for the two are even less subtle.
- Handicapped Badass: According to Vulcanus, she has bad hearing and eyesight, and can't walk (similar to her namesake). Her power over objects more than compensates for this, though.
- If You Ever Do Anything to Hurt Her...: Vulcanus has made it clear to Keima that she will never forgive him if he ever hurts Tsukiyo.
- Mind over Matter: This is Vulcanus' main power - and she can do some terrifying things with it.
- Onee-sama: Being the eldest of the Jupiter Sisters, Vulcanus is highly respected and admired by her younger sisters.

- Squishy Wizard: She has excellent telekinetic powers, but not only is she physically weak, she's actually crippled and nearly deaf and blind.
- What Does She See in Him?: Vulcanus doesn't understand how such a pure and beautiful girl like her host could have fallen in love with someone like Keima.
CLICK HERE TO SEE MARS'S FORM
Voiced by: Ayahi Takagaki (JP), Krystal LaPorte (EN)The next goddess found after Vulcan, Mars appears to be the most physically powerful, as befits her name. Mars seems serious and businesslike to the point where she seems completely inexperienced when it comes to love and romance. However, she agrees to help her host capture the target of her affections in return for assistance in finding her sisters.She is the third youngest of the Jupiter Sisters.
- Action Girl: Comes with her position as the Goddess of Battle. She's the only one who put up a notable fight against Vintage, though Lune still beat her fairly easily.

- Captain Morgan Pose: Before heading out to hand the colossal Weiss their collective asses in FLAG 265.

- Lady of War: Her manners aren't particularly exceptional, but her appearance is quite refined, she uses a Royal Rapier and she's in a position akin to royalty. She looks it too.
- Lightning Bruiser: Fast, powerful and durable.
- Rapunzel Hair: Her hair extends past her waist.
- Red Eyes, Take Warning: Apart from the change in hair color, she also turns Yui's eyes red. Plus, she's the Goddess of War.
- Royal Rapier: Her host Yui Goidou uses a prop one during her date with Keima, but Mars wields it expertly against the "evil agent of Vintage."
- Running Gag: A small one: Confusing Yui for a guy.
- Sacrificed Basic Skill for Awesome Training: Mars is a War Goddess and has always been on the front lines of battle, which has apparently left her with little of a social life.
- Slipknot Ponytail: When Mars takes over to fend off the 'Evil Vintage agent,' AKA Haqua.
- Super Strength: To her host's surprise, a light push from Mars is enough to send a punk flying backwards.
- Tomboyish Ponytail: Just like her host she has long hair tied up at the back, except she has even more of it.
- Tsurime Eyes: Her sharp eyes contrast her host's Tareme Eyes.
- Unfamiliar Ceiling: Mars goes through this when she wakes up, quizzing her new host on where she is.
- War Goddess: Mars is named after the Roman god of war and appears to be the most physically powerful goddess of the Jupiter Sisters.

- Adorkable: She's awkward, quiet and naive.
- Astral Projection: She is able to manifest herself in a ghostly form outside her host's body.
- Barrier Warrior: Minerva can manifest force-fields to protect herself or others.
- Cute Bookworm: Like her host Shiori, Minerva is definitely the bookish type and is spotted around the library several times before her capture.

- Shrinking Violet: Not only does she almost never talk, she tends not to finish her thoughts before getting too nervous and quitting.
- Token Mini-Moe: Most childlike of the Jupiter Sisters, though not actually the youngest.
- Visible Silence: Her most common line is '...'
- You Gotta Have Blue Hair: While in possession of Shiori's body, she turns her host's hair light bluish purple.
CLICK HERE TO SEE MERCURIUS' FORM
Voiced by: Ayana Taketatsu (JP), Elizabeth Bunch (EN)The final goddess and the one Keima has of course been trying to find the whole time, Mercurius is considered to be something of an oddball. While the other sisters all have a particular strength, Mercurius appears to have more interest in learning weird spells. For her capture, Keima is unsure of her host and thus has to pursue more than one girl at once.She is the youngest Jupiter Sister.
- Big Little Sister: To Minerva. While Minerva is the second youngest of the Jupiter Sisters and Mercurius the youngest, Mercurius is much taller than Minerva.
- Dark-Skinned Blonde: She seems to affect her host's appearance more than most goddesses. Her skin becomes brownish and her hair turns white in addition to the Facial Markings.
- Facial Markings: She has some small stripes beneath her eyes.
- Mystical White Hair: Her hair is white and her sisters say she's the specialist with regards to unfamiliar/bizarre spells.
- Peek-a-Bangs: One eye is always covered by her very long bangs.
- Sleepyhead: She always appears drowsy and spent most of her capture asleep while her host ran about. Afterward, she slept through the party the goddesses held and just woke up at the end to announce that their arguing was pointless since Ayumi and Keima just got married, right?
- Super Speed: While her namesake's known for his speed, Mercurius' own abilities in this regard are unclear, though she has used it. Minerva thinks Mercurius would be the fastest absent the use of powers, and indeed she wins a race between the goddesses with that handicap in place, even though she was asleep at the starting line. (To be fair, though, the other goddesses did eat Elsie's cooking along the way...)
Bell Mark Atsume
A New Devil that appears in the Kanon spin-off. She used to work as an idol prior to getting stuck as a child and aims to Take Over the World.
- Casting a Shadow: She envelopes an entire city with darkness, since Devils come from a realm of darkness and can withstand darkness and cold much better than humans. She would have liked to do the same thing to the entire human world, but fortunately doesn't have anywhere near that sort of power.
- Combat Pragmatist: She takes full advantage of the fact that devils can handle the cold much better than humans in her musical duel with Kanon.
- Familiar: She has a Stray Spirit that takes the form of a demonic owl to serve her.
- Fountain of Youth: Just like Kanon, she is stuck with the body of a child, except when she uses The Power of Song to transform into a Dark Magical Girl.
- Heel–Face Turn: Implied to have made one by the final chapter. We just don't know when.
- Magic Idol Singer: Just like Kanon, she uses a combination of Hellian magic and The Power of Song to transform into one.
- Puny Earthlings: She makes sure to emphasize just how inferior humans are to her kind.
- The Rival: To Kanon.
- Take Over the World: Her ultimate goal, not that it's anything to be taken seriously.
