- Animal Motif: Unsurprisingly, all of them are associated with the animal their Anima came from—Cooro with crows, Husky with fish, Senri with bears and Nana with bats.
- Dark and Troubled Past: The basic idea of how you get an Anima to begin with.
- Family of Choice: To each other, natch.
- Traumatic Superpower Awakening: A trait of all +Anima.
- True Companions: Oh heck yes. These kids love and care for each other just like a family, with even both Senri and Nana turning down the chance to have a permanent home to go with them.
- Walking the Earth: Pretty much what they're doing for the majority of the series.
A young crow +Anima and the series' main protagonist.
- The Ace: The most skilled in using his Anima, probably because he was born with it. Later turns out to be a Broken Ace as well.
- Adorkable: His naive personality makes him very lovable.
- All-Loving Hero: Always willing to help people out.
- Big Eater: Boy, does Cooro love to eat!
- Bishōnen: Not on Husky's level, but he's still prettier than your average teenage boy.
- Break the Cutie: Thanks a lot, Fly.
- Creepy Crows: What he's associated with. His actual personality averts this.
- Dark Is Not Evil: His giant crow wings often lead to him being mistaken for a harbinger of death or ill fortune. This usually ends when he starts talking.
- Dull Eyes of Unhappiness: During his suicide attempt in the final volume.
- The Ditz: Lampshaded by Husky. A lot.
- Extreme Doormat: Played for drama. No matter what he does, if someone wants him to do something, he'll gladly do it, even if it hurts him and without ever even thinking about how it will affect him. Fly has been taking advantage of this for years and Husky talks Cooro out of killing himself by telling him to stop being a doormat and treat himself as well as he treats everyone else.
- Fatal Flaw: His biggest one is his Extreme Doormat status, which Husky lampshades in the final volume, noting that no matter what, Cooro will always seek to please others and do what they want, without ever thinking of what he wants. He's also way too trusting for his own good. And Fly exploits both of these flaws as much as he can.
- The Heart: Possibly moreso than Nana!
- Heterosexual Life-Partners: With Husky...maybe.
- Hidden Depths: He's apparently pretty good at singing.
- Keet: Super energetic, probably having to do with the fact that he's part-bird.
- Nice Guy: Always trying to help people. Kind of deconstructed too, though, as it leads to him being a little too trusting of people and far too eager to please.
- Platonic Life-Partners: With Nana.
- Sensor Character: To a limited degree. He's somehow able to tell whether or not someone else has an Anima, which is why Fly uses him to recruit test subjects.
- Stepford Smiler: He's a cheerful guy, but there's a lot of sadness he's hiding underneath that smile.
- Trademark Favorite Food: Apples!
- Winged Humanoid: His Anima, of course.
A fish +Anima and the first major character Cooro meets, working at a traveling circus as a "mermaid princess".
- Ambiguous Gender: Parodied. He's definitely a boy, something he makes abundantly clear, but his ridiculously gorgeous and feminine appearance makes pretty much everyone who meets him question this.
- Ambiguously Gay: Well, between the crossdressing, the Ho Yay with Cooro and the hatred of girls...
- Armor-Piercing Response: In order to snap Cooro out of killing himself, he says this:Husky: What about you, Cooro!? Try telling us what you want for once!
- Berserk Button: Do NOT mistake him for a girl. And especially don't flirt with/hit on him after doing so.
- Bishōnen: Oh boy. This kid gets mistaken for a girl so often that even his best friends question him sometimes.
- The Dandy: For a teenage boy, he's surprisingly fond of jewelry and fancy clothes.
- Dude Looks Like a Lady: To the point that his first job was a crossdressing gig. Heck, even his friends question him sometimes!
- Effeminate Misogynistic Guy: He doesn't like girls, with his excuse being that he was teased for his feminine appearance. We later learn that it has more to do with a female relative trying to murder him. He warms up to Nana just fine, though. Kind of.
- Fatal Flaw: Has a slight issue with Pride and Anger.
- Ironic Fear: Played for drama; he's often noted to have a fear of drowning, due to the incident that got him his +Anima in the first place.
- Jerk with a Heart of Gold: He cares deeply for his friends despite being so abrasive.
- Lonely Rich Kid: In his youth.
- Mystical White Hair: His hair is a silvery color and he has animal shapeshifting powers.
- Only Sane Man: Sometimes.
- Our Mermaids Are Different: His Anima manifests in a way that makes him look like a merman.
- Snark-to-Snark Combat: Frequently with Nana. Borders on Belligerent Sexual Tension.
- Team Dad: Along with Nana, he generally tries to keep everyone from going crazy.
- Tsundere: Toward Nana and Cooro.
- Trademark Favorite Food: Word of God states that Husky's the only member of the group who averts this; he has preferences, but he doesn't have a set favorite.
- Vocal Dissonance: Despite his feminine appearance, he has a gravelly voice, from which he gets his name.
A bear +Anima who was first seen protecting a small town called Abon from the greedy Garrison Gang.
- Bears Are Bad News: Usually averted. He's a friendly guy, until you mess with his friends. However, without his eyepatch to keep it in check his Anima can drive him into a bloodthirsty rampage.
- The Big Guy: He's the biggest, tallest and strongest of the group.
- Bishōnen: A more masculine example than most, but he's still pretty enough to qualify.
- Chick Magnet: In his first appearance, the ladies of Abon all absolutely love him, Rose had a thing for him for a while, and even Nana seemed to be crushing on him early in the story.
- Cloudcuckoolander: At first glance, he seems like the standard tall, dark and stoic character, but dig a little deeper and you find that he's a bit...strange.
- Expy: You'd be forgiven if you thought he was Takashi Morinozuka for a second.
- Eyepatch of Power: Well, more like Eyepatch of Limiting Power.
- Friend to All Children: Children love the guy. Although downplayed (and possibly justified) because technically he's a kid too (he's sixteen/seventeen years old).
- Friend to All Living Things: He loves plants for one thing.
- Gentle Giant: He's the tallest and strongest, but he's also sweet as can be.
- Iconic Item: His flower collecting book.
- Long-Haired Pretty Boy: He has very long hair and is a total cutie.
- Mr. Fanservice: Handsome, kindhearted, has a few Shirtless Scenes and has been shown to have a fair amount of admirers in-universe and out.
- Nice Guy: One of the friendliest and most chivalrous characters in the cast.
- Papa Wolf: He may be a Gentle Giant, but if you mess with his friends, he will show no mercy.
- The Quiet One: He rarely speaks, and when he does people tend to be surprised. Cooro suggest that he hates talking, his admirers in Abon think he's shy.
- Ship Tease: With Rose.
- Supreme Chef: He's very good at cooking.
- Terse Talker: In the rare times he does talk, it's usually in very short (sometimes one word) sentences.
- Trademark Favorite Food: He likes honey. And yes it is partly because he's part bear.
- Undying Loyalty: To his friends and Lady Crystala.
- Wolverine Claws: But only on his right hand.
- Younger Than They Look: Would you seriously believe that he's only about 17-years-old?
A bat +Anima and the last major character we meet, living in the underground of a town called Octopus and ostracized by the girls who also live there.
- Action Girl: Despite being more passive than the others, she's still capable of holding her own.
- Classy Cat-Burglar: Tries to be this at one point. She fails hilariously.
- Covert Pervert: Downplayed, but she seems to have a weakness for attractive boys.Nana: (after Husky scolds her for not stunning a guy they were chasing) And besides, he was so cute! I couldn't possibly stun him!
- Cowardly Lion: A bit more panicky than her friends, but she can be brave when she has to be.
- The Cutie: She's so dang adorable!
- Gold Digger: Played for laughs as she has the very lofty life goal of marrying into a rich family someday. She even considers marrying Husky because he's rich!
- Hair of Gold, Heart of Gold: She has brownish blonde hair and is a total sweetheart.
- The Heart: One of the kindest members of the group. That's not to say she doesn't have a dark side, though...
- Ironic Fear: Lampshaded by Husky at one point—she's part-bat, but is also afraid of dark forests, a habitat bats are known to frequent and that, due to her powers, she should have no problem traveling through. Like Husky, it's played for drama and justified because of her backstory.
- Little Miss Snarker: Mostly towards Husky, but Nana's far more sassy than one would expect at first glance.
- Make Me Wanna Shout: One of her Anima abilities is a sonic screech that can stun anyone who hears it. The problem is, she's not very good at controlling this ability.
- Ms. Fanservice: Parodied; she's WAY too young to be a straight example, but she tries anyway during her brief stunt as "Phantom Thief Nana".
- Nice Girl: Though like Cooro, she can be a little too nice for her own good.
- Pride: She can occasionally display this, which Husky is usually quick to mock.
- The Smurfette Principle: The only girl among the main cast.
- Snark-to-Snark Combat: Frequently with Husky. Borders on Belligerent Sexual Tension.
- Superpower Lottery: Combining flight, sonic screams, echolocation and superhuman hearing makes her Anima the most versatile in the main cast, if not the series.
- Team Mom: Even moreso in the unserialized version of the story in the second volume, where she can be seen scolding Cooro for trying to eat something off the ground.
- Tomboy and Girly Girl: The girly girl to Rose's tomboy.
- Trademark Favorite Food: Baked goods, especially bread.
- Tsundere: Of the DereDere variety—she's generally sweet, kind and nurturing, but she's shown a few times to have a manipulative, prideful side. Her "Tsun" tendencies usually come out when she's around Husky.
- Winged Humanoid: Has bat-like wings as part of her anima.
A young woman the group meets who turns out to be a cat +Anima.
- Action Girl: Excellently helps fight off two giant birds that attack Cooro.
- Animal Motifs: She's a cat girl.
- Big Sister Instinct: She does not take kindly to finding out that the Research Institute is trying to use her little brother.
- Cat Girl:...Kind of. She only gains claws, slitlike pupils and fangs. No ears and no tail.
- Cool Big Sis: To her brother Pinion and later to Nana.
- Ms. Fanservice: One of the more adult-looking ladies in the cast and very attractive.
- Nice Girl: Granted a lot of people are pretty nice in this series.
- Ship Tease: Was sweet on Senri for a while. It never really goes anywhere though.
- Tomboy and Girly Girl: The tomboy to Nana's girly girl.
- Tomboy with a Girly Streak: She comes off as a tomboy, but makes a living selling and making jewelry.
- Younger Than They Look: She's actually 16.
Rose's little brother.
- Distressed Dude: Held captive by the Research Institute in an effort to use his Photographic Memory as a means of spying on opponents. He's saved by the combined efforts of Rose, our heroes and Magdala.
- Identical Stranger: Well, kind of. He's a lot like Senri, though he's much younger.
- Photographic Memory: Has one and he records it through drawings. He's actually experimented on for a while because of it, which his sister does not take well.
- The Quiet One: He rarely speaks.
Commander of the Astarian army. He isn't fond of +Anima.
- Childhood Friends: With Fly.
- Enemy Mine: He ends up allying himself, at least somewhat reluctantly, with Kim-Un-Kur at one point. He manages to be surprisingly civil with them, though he's still noticeably tense.
- Fantastic Racism: Against +Anima and Kim-Un-Kur (Senri's people).
- Freudian Excuse: His grandfather was killed by a +Anima that also happened to be a Kim-Un-Kur. Ouch.
- Jerk with a Heart of Gold: He's more reasonable than one would expect.
A well-known blacksmith first introduced when Igneous demanded weaponry from him.
- The Blacksmith: Was well sought out for his swordcrafting skills, but he retired from making weapons due to seeing them be used for cruel purposes. Now he only makes domestic things, like shears, kitchen knives, etc. things with practical uses...which several soldiers end up admitting are still very well crafted.
- Cool Old Guy: In general, the way he is towards both the main kids and his wife.
- Declaration of Protection: Considers himself Margaret's guardian.
- Happily Married: To Margaret. Their life is so content that Margaret's Anima faded.
- Nice Guy: Holds no ill will toward +Anima.
Harden's wife and a former deer +Anima.
- Animal Motifs: Deer are docile, elegant animals. Fits Margaret like a glove.
- Brought Down to Normal: Lost her Anima due to the fact that, with Harden's Declaration of Protection coupled with their wedded bliss, she no longer needed it.
- Cool Old Lady: She's as cool as her husband.
- Happily Married: To Harden, so much so that her Anima faded.
- Housewife: Harden mostly crafts tools for her to use nowadays.
- Nice Girl: She's kindhearted and motherly.
- Our Centaurs Are Different: How her Anima manifested, with the legs and ears of a deer.
A young woman who is fascinated by +Anima.
A peddler woman from Sailand who hopes for the independence of enslaved +Anima in Sailand.
- Bifauxnen: Frequently disguises herself as a beautiful man and looks very similar to her twin brother the King of Sailand.
- Cool Aunt: To Husky, whom she taught how to fight.
- Happiness in Slavery: An interesting case. Many of her slaves, especially Daisy and Senri, display Undying Loyalty to her, but to even call them slaves would actually be a bit of a stretch, as Crystala allows them as much freedoms as she can and doesn't force them to work for her. They're so happy in her service, that one vivid memory a colleague of hers had was them getting nervous when she ordered them to remove their collars on their way to Astaria , worried that she was going to abandon them.
- The Mentor: Taught Husky how to fight with a staff when he was a kid.
- Old Friend: To Senri and Husky. She's the one who gave the former his book and eyepatch and the one who taught the latter how to fight with a staff.
- Parental Substitute: Despite Nana's assumptions that it's something else, Crystala very clearly acts like a mom to Senri.
- Rebellious Princess: Implied; as the King's twin sister, she's royalty, though it's implied that due to Sailand's laws of succession, she doesn't have the power he has and thus can't change the system herself. Hence, she ran away and started up her caravan, hoping to make life better for the +Anima in Sailand.
- Sympathetic Slave Owner: Despite owning slaves herself, she truly disapproves of slavery and despite being related to royalty, the laws of Sailand make her incapable of reforming the system herself. It's implied that part of the reason she buys slaves in the first place is to ensure that they don't end up in the hands of someone cruel and she notes that while she doesn't agree with the status quo, she has to go along with it as there's no way currently to change the system.
A coyote +Anima and one of Crystala's slaves.
- Animal Motifs: Energetic and loyal, fitting perfectly with her status as a canine +Anima.
- Genki Girl: Very energetic.
- Happiness in Slavery: Played with; Daisy adores Crystala and is quite offended at the idea that Nana and Cooro wouldn't want to join her caravan. That said, to call her situation "slavery" at this point would be kind of a stretch, as Crystala most certainly does not treat her this way. Indeed, Daisy does not quite see herself as one (which pleases Crystala) and is insulted by Kazana's insinuation that she doesn't serve Crystala by choice.
- Little Bit Beastly: She obtains a tail and coyote ears upon shifting.
- The Nose Knows: It's implied that one of the perks to her being a coyote +Anima is having a keen sense of smell.
- Undying Loyalty: Befitting a canine +Anima, she's quite loyal to Crystala.
A slave trader who works with Lady Crystala sometimes.
A hawk +Anima and one of Lady Crystala's former slaves.
- Animal Motifs: Birds of prey like hawks are symbols of strength and justice, fitting with his fight for equality. Hawks however, are usually seen as less noble than animals like eagles, reminding us that Kazana is also an extremist who may end up doing more harm than good.
- Does Not Like Shoes: Due to his anima manifesting as having talons for feet.
- Freudian Excuse: His reason for defecting from Crystala was the discovery that she is related to the king, leading him to believe that she had the means to change the system herself but didn't. The truth is more complicated than that, though.
- Little Bit Beastly: Gains not only wings, but also hawklike talons on his feet.
- Noble Bird of Prey: A boy with hawk powers and a strong sense of justice.
- The Rival: Senri doesn't like him at all.
- Well-Intentioned Extremist: Hoped to assassinate Sailand's king in order to obtain justice for his fellow +Anima. Crystala points out to him how this will undoubtedly backfire on him, as all it will do is make the public more convinced that +Anima are violent and need to be controlled.
- Winged Humanoid: Being another bird +Anima, this is to be expected.
One of the Sailand King's many wives and Husky's mother.
- Good Parents: She loves Husky dearly and despite her happiness at reuniting with him, is willing to let him leave Sailand for his own sake, knowing that his status as a +Anima will lead to his persecution.
- The High Queen: Implied to be a benevolent queen and truly loves her son.
- Never Suicide: A variant; when Dylana tried to murder Husky, she spread a rumor that he killed himself. Marerin, however, didn't believe her, as she notes that Husky would never have killed himself, and is implied to have been constantly showing suspicion of her fellow queen for a long time.
- Parents Know Their Children: Double subverted. She gazes upon Husky with shock when she sees him alive...then orders the guards to "sieze him". THEN she treats him and his friends to a nice meal and asks him questions to see if he's really her son, which he confirms to her.
One of Husky's half-brothers and the next in line to be King of Sailand.
- The Bully: Bullied Husky relentlessly, usually about his voice and feminine looks.
- Dude Looks Like a Lady: You can't help but wonder why he'd pick on Husky for looking like a girl when he looks pretty feminine himself.
- My God, What Have I Done?: He started regretting his bullying after Husky seemingly committed suicide.
- Spoiled Brat: Started out as one. This changed after Husky's "suicide".
Keane's mother. Another one of the King's wives, who had a fierce rivalry with Lady Marerin.
- Alpha Bitch: Really did not like Lady Marerin and Husky even says that the two bullied each other.
- Evil Aunt: Well, sort of this to Husky. Wanting Keane to inherit the throne instead of Husky, she tried to drown him in a pond and told everyone he committed suicide. This is why Husky became a +Anima.
- Karma Houdini: No one ever really finds out that she tried to murder Husky and thus, she's never punished for it. Although her son is likely not going to follow in her footsteps now that he knows the truth.
A researcher who seems to know an awful lot about Cooro.
- Asshole Victim: After what he put Cooro through, it's hard to feel any sympathy for him when he falls to his death.
- Big Bad: By the end of the story, he's the closest thing to a major villain we've got.
- Bitch in Sheep's Clothing: Beneath his kindhearted exterior, he's a selfish creep.
- Bunny-Ears Lawyer: A highly intelligent researcher who still calls his childhood friend by a childish nickname.
- Childhood Friends: With Igneous.
- Composite Character: Of Greena Eito and Mr. Gates from the pre-serialization "Parallel" stories, having Greena's appearance and name and Gates' personality.
- Does This Remind You of Anything?: His interactions with Cooro are disturbingly similar to the actions of a child molester.
- Expy: A researcher who looks and acts remarkably similar to him (minus the whole being evil thing) appears in the non-serialized version of the story the author posted in volume two. It seems this researcher was a bit of a prototype for him.
- Fatherly Scientist: Subverted; he acts like this toward Cooro, but really he's doing it as a means to a selfish end.
- Faux Affably Evil: He seems like a relatively nice guy, but then he turns out to be a selfish manipulative asshole.
- Four Eyes, Zero Soul: Wears glasses and is an utterly despicable human being.
- It's All About Me: Can't be bothered to care when his actions lead Cooro to suicidal depression.
- Karmic Death: Fly wanted to...well, fly, right? Well he got to. Very briefly. Then, down, down, down he went.
- Kick the Dog: "Yes, you have no mother or father. You were made by me and Aaron." Just to clarify, this revelation was not only a lie, it turned Cooro into an Empty Shell.
- Mad Scientist: Wants to become a +Anima so he can fly with Blanca.
- Manipulative Bastard:Manipulates Cooro every chance he can get.
- Never Found the Body: Marca, Fly's assistant, says that he has gone missing.
- Nice Guy: Seems like a pretty friendly guy. Turns out he's actually Faux Affably Evil.
- Pride Before a Fall: An actual fall even.
- Scary Shiny Glasses: The first time we see him, he has these.
- Smug Snake: For all his research, he somehow had no idea that +Anima powers become less stable when removed from their masters, leading them to go back. He ends up learning this the hard way...
- Stalker Without a Crush: To Cooro. Dear God, poor Cooro...
- Stoic Spectacles: Although they're more like Four Eyes, Zero Soul.
- Used to Be a Sweet Kid: A flashback reveals that Fly used to be a genuinely kind child with a strong love of science and research. He kept the latter, not so much the former...
- Walking Spoiler: Knowing too much about him spoils a major aspect of his character.
- Cool Old Guy: The elder.
- Fangirls: Many of the female residents are very sweet on Senri.
- Supreme Chef: Abon is famous for its cuisine.
- Token Good Teammate: They're among the few people who accept the presence of a +Anima, in this case, Senri, because he protects their town from the Garrison Gang. When the Garrison Gang leaves, Senri doesn't have much of a reason to stay anymore.
- Arc Villain: Of Senri's introduction.
- Greed: They believe Abon is full of gold and thus they want to take over the place.
- The Mafia: They give off vibes of this.
- Noblewoman's Laugh: The leader has one, or at least, she does the limp wrist to the face pose when she laughs.
- Samus Is a Girl: The leader is revealed to be a supremely beautiful woman.
- Smug Snake: The leader believes Abon Weed and Gold Indicator Weed to be one and the same and thus comes to the conclusion that Abon is full of gold. She's proven wrong at the end, as Abon Weed is actually completely different from Gold Indicator Weed—their leaves are similar but their flowers are different.
- Amazon Brigade: All of them are girls and Delly mentions that there are no boys allowed in their clubhouse. They make an exception for Cooro, Senri and Husky after Senri saves one of her friends.
- Anti-Villain: They're not bad people, but Delly hates +Anima out of jealousy and treats Nana fairly harshly. She comes around at the end.
- Arc Villain: Of Nana's introduction...kind of.
- The Artful Dodger: All of them.
- Fantastic Racism: Delly displayed this toward +Anima, though it turned out to be mainly due to jealousy.
- Condescending Compassion: He thinks he's on the receiving end of this when he discovers that Cooro can fly. He realizes soon after that it's not so and apologizes.
- Fantastic Racism: Subverted, which is interesting in a series like this—he's angry when Cooro turns out to be a bird +Anima, but not because he hates +Anima; it's because he was trying to build a glider so he could help his family out more easily, and discovering that Cooro (who offered to help him with this goal) could fly on his own the whole time made Shadow feel like he was being lied to and insulted. He apologizes when Cooro flies in to save him during a storm.
- Farm Boy: His family owns a goat farm.
- Gadgeteer Genius: Downplayed; he's working on making a glider.
- Interspecies Friendship: At the end of his introduction, it's revealed that his "sisters" are actually a group of goats from his family's farm. He states that he still loves them like they were his actual sisters, though.
- My Greatest Failure: The reason he's making a glider is because some time ago, one of his sisters fell ill and he couldn't get to her with medicine in time, leading to her death. This is only slightly mitigated by the fact that his "sister" was actually a goat, though as he states at the end of his arc, he views his family's goats as being like family to him so the emotional impact is still there.
- Nice Guy: He does blow up at Cooro when he discovers he could fly the whole time he was helping him with a glider, but despite this he's shown to have a good heart.
- Tastes Like Friendship: He and Cooro first start bonding over goat cheese.
- Dark Is Not Evil: He starts out seemingly being a "monster", but it turns out he was just a bison +Anima who happened to like the hot springs.
- Full-Frontal Assault: Partial example; since his debut was a Hot Springs Episode, his attack on our heroes involved him only wearing a towel.
- Gentle Giant: Though he doesn't initially appear to be one due to a misunderstanding, it turns out he's actually a pretty nice guy.
- Horned Humanoid: As a bison +Anima, this is to be expected.
- Modesty Towel: Introduced in one, due to appearing in a Hot Springs Episode.
- Scars Are Forever: Retains a scar on his back that he was trying to heal in the hot springs, noting that the scar would heal faster if he healed them in his +Anima form (which is the form he got the wound from).
A spoiled girl and the heiress to the ruler of Maggie Vil.
- Elegant Gothic Lolita: Her taste in fashion.
- Facial Markings: She has star-shaped markings near her eyes.
- Freudian Excuse: She had no friends and otherwise spent much of her childhood being catered to, which is implied to be why she assumed she could just force people to be her friends.
- Heel Realization: After Sinon becomes a +Anima just to get away from her and Cooro and Husky talk some sense into her, she finally realizes just how awful she had been.
- Mistreatment-Induced Betrayal: Turns against her mother's wishes when her mother decides to override her authority.
- Never My Fault: Has a big problem with this. When Husky explains to her that Sinon became a +Anima specifically because she was trying to kill him, she tries to twist this into "well then he should thank me because thanks to me, he can fly now!" Husky is so disgusted that he verbally tears into her, pointing out how no one chooses to become a +Anima.
- Spoiled Brat: Oh yes. She has everything she could ever possibly ask for, tries to have one of her servants killed when he asks to leave, and throws a hissy fit when he manages to escape anyway (by becoming a goose +Anima).
- Walking the Earth: She hopes to do this someday when she's older.
One of Magdala's servants.
- I Just Want to Be Free: He understandably does not like being in Magdala's snare.
- Winged Humanoid: Becomes a goose +Anima in his desperation to escape being killed by Magdala when she discovers that he's trying to escape. He's a rarity among winged +Anima in that his wings extend from his arms and not his back.
A Kim-Un-Kur chief and wolf +Anima.
- Animal Motifs: Wolves are noble creatures and born leaders.
- Animorphism: He can fully transform himself into a wolf and thus, is the only +Anima who is shown to be capable of completely transforming himself into his animal (it's mentioned that this is a rare but still possible ability for +Anima; he's the only one seen using it).
- Authority Equals Asskicking: Well, being able to transform into a giant freaking wolf may have something to do with it.
- Badass Native: A powerful man from an indigenous culture.
- Braids, Beads and Buckskins: Complete with he large headdress.
- Large and in Charge: He towers over the kids and is quite broad shouldered.
A Kim-Un-Kur and an old friend of Senri's father. Like Senri, he's a bear +Anima.
- Animal Motifs: Like Senri, he's a Gentle Giant until those he cares about are threatened, making a bear quite appropriate for him.
- Badass Native: Just like Senri and Mukar.
- Braids, Beads and Buckskins: Like all Kim-Un-Kur in the cast.
- Evil All Along: Subverted. Halfway through, he tries to kill Senri, but it's less out of malice and more because he believes Senri may be past helping due to Amurui's demonic possession. He comes around when Senri manages to overcome this with his friends' help.
- Little Bit Beastly: Unlike Senri, both of his arms turn into claws.
- Old Friend: To Senri and his father.
A monstrous bear spirit with ties to the Kim-Un-Kur.
- Animalistic Abomination: A monstrous creature who is apparently capable of demonic possession.
- Bears Are Bad News: An evil bear.
- Demonic Possession: He can consume others and take over their bodies. He does this to Senri's father and later Senri himself.
- Made of Evil: The Kim-Un-Kur usually display respect for all animals, bears especially. Not Amurui. He's pure evil and their orders upon encountering him are basically "kill on sight".
- Offing the Offspring: He had a cub before he was defeated and said cub has since grown up to be as ruthless and monstrous as he is, but after taking over Senri, he kills it.
- Greater-Scope Villain: He's the reason for Sailand's oppression of +Anima, but he barely factors into the plot until the end of Husky's arc.
A girl Cooro used to know at the church. She's a swallow +Anima when he sees her again, but not all is as it seems...
- Brought Down to Normal: Her +Anima eventually becomes unstable and dissipates.
- Driven by Envy: Asked Fly to turn her into a +Anima because she was jealous of Cooro's flying prowess.
- Fiery Redhead: She's a tenacious red-haired girl.
- Little Bit Beastly: Along with her wings, she gains the forked tail of a swallow.
- Winged Humanoid: Her +Anima manifests as a swallow's wings and tail emerging from her back.
A mysterious +Anima housed within Fly's laboratory.
- Mistreatment-Induced Betrayal: Fly has been experimenting on her and her spirit has been getting restless and angry as a result. The minute she has the means to get outside, she flies off as soon as she can.
- Our Angels Are Different: It's claimed that she is an angel +Anima and she has white wings and feathers for hair.
- Tulpa: Apparently, she's the dreams of researchers given humanoid form.
- Winged Humanoid: She's said to be an "Angel" +Anima. She's actually the living embodiment of mankind's desire for flight.
Fly's mentor and the one who first witnessed Cooro's birth.
Parallel Chapter Characters
- Animal Motifs: Alligators are masters of camouflage and ambush, fitting with how easily he hid his true nature from the main kids.
- Bait-and-Switch: Two examples regarding him:
- We're led to believe that he's the bad guy of the story and that he won't help the kids because they're +Anima. Turns out he's a +Anima too, and the villain of this piece is none other than Mr. Gates.
- We're also led to believe that he kills Mr. Gates for what he does. Instead, he destroys his pseudo-Anima suit.
- Fair Cop: Nana seems quite taken with him. None of the boys agree with her though.
- Hello Again, Officer: Implied in his first appearance. Crosses over slightly with Remember the New Guy?.
- Jerk with a Heart of Gold: Turns out to be this, since he knows how it feels to be persecuted as a +Anima.
- Never Smile at a Crocodile: His Anima involves his head turning into that of a crocodilian of some sort. He's the only +Anima known in the series who's head transforms when he uses his Anima.
- Police are Useless: Gloriously subverted—it seems he's going to let Mr. Gates off easy...then, once he has him vulnerable and alone, the fangs come out.
- Shadow Discretion Shot: His Anima is hidden by shadow. We see no details, but we do see that his head turns into that of some kind of crocodile or alligator.
- The Sheriff: No, really?
- The Un-Reveal: We don't see his Anima or the mark that comes with it, but we do see its shadow—it doesn't seem pleasant.
- Arc Villain: Of the third Parallel story.
- Bitch in Sheep's Clothing: Similar to Fly—he acts nice to Cooro, but is only doing so as a means to a selfish end.
- Decomposite Character: He and Greena Eito are both remarkably similar to Fly; Greena in appearance and name, Gates in personality.
- Laser-Guided Karma: After making a Pseudo-+Anima suit, he gets said suit destroyed by an actual +Anima.
- Mad Scientist: Very mad.
- Obliviously Evil: He seems to border on this, viewing +Anima as a scientific marvel and wanting to "research" them...mainly using Cooro as a test subject.
- Verbal Tic: "-dani?" which is translated as "now" in the English version.
