This page lists the characters of Nabari no Ou and their associated tropes.
- Ambiguously Gay: Is extremely devoted to another boy, will manipulate other boys with his own cuteness either to his own advantage or just for fun and never seems interested in girls.
- Birds of a Feather: Seemingly the basis of his friendship with Yoite; both are jaded, withdrawn stoics (at first) fighting a war with little personal meaning to them. Miharu even calls Yoite "another me."
- Dangerous Forbidden Technique: The Shinrabanshou.
- Deadpan Snarker: Prone to snarking others.
- Deliberately Cute Child: Uses his charm to get out of bad situations.
- Dynamic Character: In later chapters, lots of characters remark on how much more open and "alive" he's become.
- Emotionless Boy: Starts off the series with a very muted, apathetic personality. He becomes much more expressive over the course of the series.
- Fuuma Shuriken: sometimes creates large shuriken (manga only)
- I Just Want to Be Normal: Doesn't want to have anything to do with the world of Nabari.
- Lack of Empathy: One of his defining traits at the beginning of the manga.
- Picky Eater: Miharu lives on a diet of mostly sweets and liquids, which would explain why he weighs all of 77 pounds.
- Say My Name: Says Yoite's name a lot, though given his subdued nature it's less loud than the the typical example. In the manga's last chapter when he calls Yoite's name as they reunite, and repeats it while gazing at the scar on his hand after they separate.
- Scars Are Forever: The scar Miharu gets on his hand from stopping Yoite from killing Yae Oda is brought up again at the very end of the manga.
- The Stoic: Is apathetic to pretty much everything. Once Yoite is in the picture, though...
- Strong Family Resemblance: Looks nearly identical to his mother, Asahi. It's almost kind of creepy.
- Troll: Whenever his "little devil" persona kicks in. Complete with little wings and a tail popping up out of nowhere.
- Zettai Ryouiki: Manages this with shorts.
- Adorkable: Particularly when around Raimei.
- Badass Bookworm: Aizawa Kouichi seems like a mild-mannered and well-spoken young man often taken aback by his friends' quirks and isn't the best at ninja techniques...except when push comes to shove, he becomes a cool, level-headed, and actually professional ninja who doesn't hesitate to kill, brainwash, and do whatever it takes to free himself from the curse of immortality, even if it means siding with the enemy village.
- Blessed with Suck: Views his immortality as a curse, having grown weary after living for so long.
- Cute and Psycho: Can come off as crazy when he's defeating people and smiling while he does it.
- Fuuma Shuriken: enlarged a shuriken (anime only)
- Hellish Pupils: At times. Presumably because he's not completely human.
- I Just Want to Be Normal: He and Shijima never wanted their immortality and have grown weary of it over time.
- Like Brother and Sister: Has shades of this relationship with Shijima.
- Red Eyes, Take Warning: While he apparently isn't evil, he's certainly more ruthless than he first appears, and he's definitely planning something behind his team's back. Plus, he's immortal, and not exactly human.
- Who Wants to Live Forever?: Views his immortality as a curse.
Tobari Durandal Kumohira
- Afraid of Needles: Thobari's irrational fear of vehicles of all sorts. Apparently he used to be an award-winning choirboy in Ireland, but being forcibly brought over to Japan in an airplane traumatized him so much he became tone deaf.
- Butt-Monkey: He can't ever seem to catch a break.
- But Not Too Foreign: Partially Irish.
- Failure Knight: His devotion to Miharu is partially because of his guilt from failing to seal the Shinrabanshou 10 years ago.
- Fatal Flaw: He's morally unable to take a life, which makes it hard for him to protect Miharu. Multiple characters call him out on this. He finally gets over it by killing Hattori in the anime and Fuuma in the manga.
- My Greatest Failure: Not protecting Akatsuki, Asahi, and his grandfather and failing to seal the Shinrabanshou. The guilt from this incident weighs pretty heavily on him, compounded by the fact that he's the only person who remembers what happened.
- Papa Wolf: Towards his students.
- Phenotype Stereotype: Averted: Kumohira is partly Irish, and he does have blue eyes, but with dark hair instead of blond.
- Oireland: Averted: Kumohira averts almost all of the typical Oirish stereotypes, including drinking.
- Thou Shalt Not Kill: His personal moral code won't let him kill anyone. While this makes him one of the more honorable shinobi, it also complicates his mission to protect Miharu.
- Action Girl: A capable young samurai.
- Genki Girl: She's energetic and friendly, but does have her angsty moments.
- Honor Before Reason: She refuses to trick her opponents, preferring to face them head-on.
- New Transfer Student: Raimei's case is a little strange in that she just sort of...invades. The other students seem to love her, though.
- Oblivious to Love: She doesn't appear too aware of Kouichi's romantic feelings for her.
- Plucky Girl: Remarkably cheerful considering her past. She's also a Determinator when fighting and in regards to her Roaring Rampage of Revenge against Raikou.
- Red Oni, Blue Oni: The Red to Kouichi and Miharu's Blue.
- Roaring Rampage of Revenge: Against Raikou for killing their family. She stops after learning that he was acting in self-defense and didn't kill their parents.
- Running Gag: Her tendency to mistake people for each other when she's excited about something.
- Samurai: A self-styled one. She's Hot-Blooded and more focused on honor than most of the ninja around her.
- Town Girls: The Butch to Saraba's Femme and Juuji's Neither.
- Tsundere: She's a minor example, but she still retains aspects of a Type B around Kouichi, Miharu, and Kumohira.
- Big Bad:Turns out to be the series' true villain, wanting the Shinrabanshou to himself.
- Beware the Silly Ones: Flamboyance aside, he's a competent leader and can be quite the Manipulative Bastard. He's also the Big Bad and has been manipulating everyone in order to get the Shinrabanshou.
- Camp Straight: Wears a big white bow in his hair, teases male characters and invades their personal space, and talks in an exaggerated, flowery manner...but he also wants to turn Fuuma village/possibly the entire ninja world into his harem.
- For Science!: In stark contrast to Tobari, he's willing to sacrifice the lives of his own men to achieve his goals and willing to kill countless others to gain the power of the Shinrabanshou.
- Four Eyes, Zero Soul: Proves himself soulless by killing a four-year-old.
- Large Ham: He has very flamboyant mannerisms.
- Manipulative Bastard: It turns out that Fuuma's been tricking, playing with and manipulating everyone from the very beginning.
- Stalker with a Crush: He desires the Shinrabanshou because he wants to possess its female spirit, whom he affectionately calls "lovely Shinra".
- Big Sister Mentor: They're not related, but she does help Raimei train and look out for her.
- No Name Given: Her full name is never given.
- Motor Mouth: She talks a lot, particularly when she's nervous.
- Ship Tease: It doesn't go anywhere, but she's noted to have a small crush on Miharu.
- Big Bad: Seemed to be anyway. In the anime he is one; in the manga...
- Big Bad Wannabe: Looks like the Big Bad of the series but it's actually Fuuma
- The Heavy: Hattori appears to drive most of the plot, though he isn't actually the Big Bad — Fuuma is.
- Historical-Domain Character: Hattori Hanzou, who, unsurprisingly, was the rival of the real-life Fuuma Kotarou.
- Silver Fox: According to Miharu's grandma, anyway.
- You Have Outlived Your Usefulness: Gets this from his own secretary
- Affably Evil: Is nice enough to thank her boss for his help as he lays there dying—after she stabbed him.
- Eyes Always Shut: Justified in that she's blind. She opens them after killing Hattori.
- Even Evil Has Loved Ones: In the anime she genuinely cares for Hattori and is enraged when he dies. In the manga, however, she betrays him with a smile on her face.
- Karma Houdini: Never reaps the consequences for killing her boss.
- No Name Given: Her full name is never given.
- Older Than They Look: She's supposedly 49.
- The Starscream: Wanted the McGuffin for herself so she kills her boss when she has no more use for him.
- Wham Shot: When she opens her eyes.
- Yamato Nadeshiko: The kimono and the second spoiler.
According to Word of God, Yoite and Miharu are the series' two protagonists despite Yoite's absence after his death.
- Ambiguous Gender: Subverted. the reader (and even most characters, apparently) start out believing that Yoite is a boy. Later it turns out that he's actually... intersex. It doesn't really matter in the long run, though, and isn't gone into in much detail, only the readers now know another reason for his angst and identity issues.
- Ambiguously Gay: Like Miharu—he seems to see Miharu as his main reason for staying alive.
- Badass Longcoat: Yoite is almost never seen without some sort of thick, black coat. He won't take it off, even if it's the middle of summer or if he's soaking wet.
- Big Eater: Yoite can be seen eating huge amounts of food in the background of various scenes. He'll eat just about anything since his Kira skill is robbing him of all his senses, and has already taken his sense of taste.
- Berserk Button: Being called an Emo Kid, in the dub. In the manga, it was being called "cute".
- Blessed with Suck: Kira is a huge advantage in battle, but is also Cast from Lifespan.
- Broken Bird: Due to his abusive childhood and the fact that he's going to die soon.
- Cast from Lifespan: The Kira technique is powered by Yoite's Life Energy.
- Dangerous Forbidden Technique: Kira, which is cast from his lifespan and thus slowly killing him.
- Disproportionate Retribution: Tried to kill a delivery guy for calling him "an emo kid" ("cute" in the manga).
- Enigmatic Minion: Works a lot on his own, including his request to Miharu. Unlike some of his teammates, he doesn't care about Kairoushuu's mission at all; rather, his greatest desire is for his wish to be granted.
- Go Out with a Smile: Dies with a smile in both the anime and manga.
- Handicapped Badass: Regularly faints, always coughing his lungs out, can barely hear or see by chapter 50. Not that his opponents can tell.
- Hates Being Touched: Though he ends up allowing Miharu to touch him sometimes, "'Don't touch me" is easily the phrase he says the most.
- Hermaphrodite: We don't learn the specifics, but Kazuho says he's "neither male nor female." It's taken by his parents and Yoite himself as another sign that he's cursed and shouldn't have been born.
- Hidden Heart of Gold: Yoite reveals to Miharu that he didn't really ever have his friends as hostages because he didn't want them to die with him if he ever died unexpectedly.
- Incurable Cough of Death: One symptom of Yoite's condition.
- Nice Hat: Yoite's giant cap. Some fans have called this series "The Hat Anime." He loses it surprisingly often for something so iconic, though.
- The Quiet One: Actually gets tired from talking for a few minutes since he's used to being silent
- Scars Are Forever: Has a scar on his neck from when his parents tried to kill him.
- Shinigami: Called one by multiple characters. Flashbacks reveal that he was called this even before he obtained Kira; family members (possibly his parents) claimed he was a shinigami who had killed his mother.
- Abusive Parents: The scar on his forearm is from protecting Kazuho from their father threatening them with a broken bottle.
- Boring, but Practical: Yukimi doesn't do very many fancy ninja techniques or amazing physical feats. He does, however, have a gun.
- Child Hater: Self-claimed. It doesn't stop him from being a Papa Wolf, though.
- Kindhearted Cat Lover: They're listed among his likes, and he takes one in near the end of the manga.
- Parental Substitute: To Yoite. Later to Miharu too.
- Papa Wolf: Yukimi betrays Kairoushuu, his home and family since he was a teenager, and loses an arm in order to protect Yoite. He also becomes surprisingly protective of Miharu, even before promising Yoite to watch out for him.
- Punch-Clock Villain: Before his HeelFace Turn.
- Red Herring Shirt: Looks like a typical Mook in his first appearance.
- Cool Big Sis: She acts like one towards to her brother and also to Yoite.
- The Medic: Treats Gau, Raikou, and Miharu in addition to Yoite.
- Badass Bisexual: Confirmed by Word of God.
- Big Brother Instinct: On occasion, he displays hints of this trope towards Raimei. It's rare.
- Bishōnen: To the point that a lot of non-fans probably think he's a woman.
- Cain and Abel: The Cain to Raimei's Abel.
- Comedic Sociopathy: His abusive treatment of Gau would actually qualify as domestic violence if Gau actually minded it.
- Defiant to the End: In the manga. Luckily, he doesn't die from it.
- The Dragon: Was Hattori's right-hand man at one point.
- Drives Like Crazy: Manages to drive his car into a river on his first try.
- Failure Knight: His decision to save Gau despite his being from the surface world stems from the regret he felt from not saving his best friend five years ago.
- Fightingwith Chucks: during that period when he doesn't have Shirogamon.
- Heroic Self-Deprecation: Raikou is convinced that Gau won't wake up from his coma because he doesn't want to see his face. Which might be justified if it was anyone else, but it's Gau we're talking about here...
- Iconic Outfit: His infamous "USA-CHAN" outfit◊. It's amazingly well-known for something he was only shown wearing for a single panel in the manga.
- Must Make Amends: After accidentally causing Gau to fall into a coma, Raikou does everything in his power to find a way to save him, including reading tons of medical books and going to Alya Academy in hopes of using Daya on Gau.
- One-Hour Work Week: He apparently has a job making paper in the "front" world.
- Pay Evil unto Evil: Murders people on a regular basis for misusing ninjutsu for crimes like stealing.
- Samurai: Like Raimei, a self-styled one.
- Rummage Sale Reject: Just look at any outfit he's ever worn in the course of the series. Seriously, any of them.
- Yandere: He kills and mutilates the dead body of a man who hurts Gau.
- You Gotta Have Blue Hair: He has pink hair.
- Adorkable: Due to his Hot-Blooded personality and hero worship of Raikou, combined with being something of a Keet.
- Butt-Monkey: Often on the receiving end of Raikou's physical abuse.
- Hot-Blooded: Gau's default mode◊.
- Hypercompetent Sidekick: To Raikou. Despite being a very talented swordsman, Raikou isn't very competent in the more real-world life skills, particularly admin work, which is where Gau dutifully and diligently picks up the slack.
- Keet: Very energetic and usually cheerful.
- Morality Pet: Stops Raikou from crossing the Moral Event Horizon by blocking a katana slash meant for Raimei. Later on, his concern for Yoite drives Raikou's HeelFace Turn.
- Tender Tears: Cries when he meets Raikou for the first time, when Raikou tells him about his past, when he gets slashed by Raikou, when he intervenes in Raikou and Yukimi's fight, when he calls Yukimi on the cellphone, when Raikou gets stabbed, etc, etc...
- Tsurime Eyes: Has slanted, cat-like eyes, although they get a bit droopier through Art Evolution.
- Undying Loyalty: Completely devoted to Raikou. He only disobeys him once, and was willing to die as punishment for that.
- Wide-Eyed Idealist: The most idealistic member of Kairoushuu. He believes they're changing the world for the better and can do so even more using the Shinrabanshou.
- Yes-Man: Gau is described as being "Raikou's little yes-man". So much so, that Kazuho and Yukimi are both taken-aback when Gau absentmindedly expresses doubt in front of Raikou on his course of action.
Shijima Kurookano/ Shiratama
A mysterious member of the Alya Academy Student Council who seems to know more than she lets on. She's actually a cat with a human heart who was made immortal by a previous hijutsu user. She and Kouichi both want Miharu to free them from the "curse" of immortality.
- Cats Are Mean: She's notably more ruthless than Kouichi, an owl, is.
- Cat Ninja: A rather literal example.
- Hellish Pupils: At times. Presumably because she's not completely human.

- Older Than They Look/Really 700 Years Old: She and Kouichi are a couple hundred years old at the start of the series.
- Pint-Sized Powerhouse: Despite being the smallest character in the series, she's a skilled fighter and even manages to take down Raikou after fighting for an entire night.
- Strong Family Resemblance: With Shinrabansho, the deity she's created from, as noted by Miharu.
- Token Mini-Moe: Ironically one of the oldest characters in the series.

- Parental Substitute: Acts like one towards Yoite and Miharu.
- Team Mom: Looks after and feeds every character she meets, including Fuuma in the manga.
- Yamato Nadeshiko: By virtue of being Team Mom and probably the nicest character in the series. The "core of steel" part shows through when she thinks Yukimi might take her hostage; she offhandedly comments that it probably wouldn't work on Tobari.
- Action Girl: She appears to be rather skilled in hand-to-hand combat.
- Mama Bear: Sought revenge for her daughter.
- Mind over Manners: She mocks Tobari when she hears his protective thoughts on Miharu and playfully teases her assistant when she discovers through accidental mind reading that he's in love with her.
- Subordinate Excuse: Her assistant has a bit of a crush on her, which she discovers when she accidentally reads his mind and hears him thinking about how much he wants to comfort her over her frustrations. She doesn't return the feelings, though, but she tells him that she appreciates him nonetheless.
- Telepathy: Can look into other people's minds. Sometimes results in Mind Rape, even accidentally.
Tsukasa KoudouA boy Yukimi meets while saving a cat. He's actually Yoite's younger brother, from back when Yoite was named "Sora Koudou."
- Abusive Parents: They treated him better than Sora, but still threatened to "make it like you never existed" if he was kind to Sora and tried to make him attack his brother. He tells Yukimi he's estranged from them and is living on his own.
- My Greatest Failure: Regrets not being able to help Sora.
- Nice Guy: Very open and friendly. He also seems to have been the only person who was kind to Sora.
