Voiced by: Haruka Kudo (JP), Kelly Metzger (EN, pre-timeskip), Kristie Marsden (EN, post-timeskip), Roser Vilches (Spain), Mireya Mendoza (Latin America)Light's little sister, who has the bad luck of being a normal kid in this messed up environment. She's completely unaware of her brother's occupation as Kira. After her horrible kidnapping by Mello, she ends up catatonic and in a wheelchair. Word of God says she's getting better at the end of the manga.
- All Women Love Shoes: According to the Guidebook.
- Ambiguously Bi: To recap: she first says that she "doesn't want a boyfriend." Then she exclaims that Misa is "my type!" And she smiles when leafing through one of Light's magazines. The ambiguity here is that she does fangirl over Hideki Ryuga (the pop star) and proclaims him perfect. She also states that she might at least consider going out with Matsuda if he were closer to her age.
- Annoying Younger Sibling: In the first half of the manga, in which she'd tease Light about Misa or generally poke fun at his lifestyle.
- Big Brother Worship: "My big brother's a genius!" Taken even further in The Musical, where she says she disapproves of Kira's actions, and thinks he could learn a thing or two by following Light's example. She even gets a song about it, appropriately titled, "My Hero."
- Bound and Gagged: When kidnapped by Mello.
- Break the Cutie: The second part of the series is so damn cruel to her. Especially when she winds up practically catatonic and wheelchair-bound, due to her shock and depression after her being kidnapped. Then her father dies. She's last shown in a brief cameo in chapter 98, standing once more but vacantly smiling (Word of God said she was "slowly" getting better). Then Light dies, and we never get to see how her and her mother react.
- Brown Eyes: Which reflect her honest, sweet, warm nature.
- Damsel in Distress: She spent several chapters in Mello's captivity.
- Empty Shell: After she's rescued by her father, she becomes this. Her last cameo in the manga (omitted for the anime) features her standing once more and smiling for a holiday ceremony in Japan, although she still has an eerie vacant look to her face.
- Fangirl: "HIDEKI RYUGA!!!"
- Foolish Sibling, Responsible Sibling: Sayu is the foolish sibling to Light's responsible - and frequently bugs him to help with homework. Subverted once Light becomes Kira.
- Genius Ditz: Despite her rather dim disposition, her conceptualization power is apparently 9/10, the same as the genius who captured Kira, Near. Just look at the ease in which she manipulates Light into doing her homework for her... it must run in the family.
- The Ingenue: Sweet, caring, innocent, and doesn't seem very smart.
- Morality Pet: She exists to give Light Pet the Dog moments and to be kidnapped. Complete with Lampshade Hanging:Ryuk (to Light): I guess even you have a soft spot for your sister.
- Nice Girl: Sayu comes off as a sweet, friendly girl — who got in way over her head.
- Parental Favoritism: A minor example. While Soichiro doesn't completely deny the possibility that Light could be Kira (and he is), he is adamant that Sayu couldn't possibly be the killer.
- She Is All Grown Up: After the Time Skip. You can't blame Matsuda for crushing on her.
- Ship Tease: Sayu drools over Misa and she says she might consider going out with Matsu if he wasn't so old.
- Spoiled Brat: Particularly in the live-action drama, but to a lesser extent in the anime/manga series proper.
- The Teetotaler: Word of God says that she dislikes alcohol.
- The Ugly Guy's Hot Daughter: Neither Soichiro nor Sachiko is particularly good-looking, but Sayu is pretty enough that Mastuda developed a crush on her.
Voiced by: Ai Satou (JP), Saffron Henderson (EN), Azucena Díaz (Spain), Erika Rendón (Latin America)Soichiro's wife and Light and Sayu's mother. Like Sayu, she is completely unaware of Light's identity as Kira.
- Break the Cutie: Near the end, her husband's dead and her daughter been traumatized from the kidnapping. We see her alone in the dining room which was once so full of life from her family now completely empty. After a moment, she breaks down and cries. And of course, she still doesn't know her son is an infamous serial killer and by the end of the day's events, she's going to lose him as well.
- Death by Adaptation: In the TV drama, she's been dead for ten years when Light finds the notebook.
- Education Mama: Quite possibly. In one of her few appearances she gushes over Light's report card while Light himself looks rather depressed and anxious.
- Happily Married: To Soichiro.
- Neat Freak: In the manga she's shown cleaning her spotless house in almost every scene. Probably where Light gets it from.
- Posthumous Character: In the TV drama, Soichiro's absence during her death, combined with his long hours spent away from home due to work, puts a strain on his relationship with Light, which is amplified since Light must look after Sayu. In the first episode, Light saves Soichiro from the criminal who previously killed Sachiko.
- Yamato Nadeshiko: She's a strong woman who does everything she can to keep the family from falling apart during the case.
Voiced by: Naoko Matsui (JP), Tabitha St. Germain (EN), Nicole Oliver (English dub of live-action films) , Alicia Laorden (Spain), Claudia Contreras (Latin America)Raye Penber's fiancee and former FBI Agent who worked under L in the L.A.B.B. murder case.
- Action Girl: Of the Dance Battler variety, since she's well-versed in Capoeira and trains L in it.
- Adapted Out: She's no where seen in the live-action drama.
- Alone with the Psycho: Twice!
- Ascended Extra: Both in the prequel novel and in the live-action movies.
- Betty and Veronica: Though it's gender swapped with Beyond Birthday as the Veronica and Raye Penber as the Betty.
- Born Unlucky: Her "luck" rating is 1/10. Ouch.
- Capoeira: She was actually the one who taught L this martial arts.
- Color-Coded for Your Convenience: Official color seems to be blue.
- Driven to Suicide: Averted; while she does end up committing suicide, she is never driven to it, and does not do it of her own volition.
- Dull Eyes of Unhappiness: When she's Driven to Suicide.
- Horrible Judge of Character: Well, Light seems trustworthy enough...
- Just a Kid: She's had... trouble with this. In the novel, it explains that she had a traumatic experience with having faced down a gang member that was no more than a child. Then there's Light the mass murdering high school student...
- Mauve Shirt: She ends up getting a few episodes worth of solid characterisation before her death at Light's hands.
- Names to Run Away from Really Fast: At the F.B.I. she was known as "Misora Massacre" for her Badassery.
- Never Found the Body: When Light wrote her name in the Death Note, he stipulated that she would kill herself in such a way that her body would never be found, so she just walks off into the distance and is never seen again.
- Noodle Incident: Commits suicide in a way that prevents anyone from finding her body. Even Light shows a bit of morbid curiosity about how exactly she achieves that.
- Not So Stoic: In her literal final seconds as she learns that Light is Kira.
- Oh Crap!: The sheer amount of terror on the poor girl's face after learning Light was Kira was just heartbreaking.
- Quitting to Get Married: Naomi has agreed to do this because her fiance, Ray Penber, worries about her in her line of work.
- Real Women Don't Wear Dresses: Word of God says that she dislikes skirts.
- Revenge: She wants to catch Kira to avenge Raye's death.
- Right in Front of Me: In Another Note when L asks her if “Ryuuzaki” was cool:Naomi: No, absolutely not. He was creepy and pathetic, and so suspicious that if I weren't on leave, I'd move to arrest him the moment I laid eyes on him. If we divided everyone in the world into those that would be better off dead and those that wouldn't, there's no doubt in my mind that he'd be the former. Such a complete freak that it amazes me he hasn't killed himself.
- Sacrificial Lion: Her purpose in the series turned out to be built up just so she could prove that Anyone Can Die.
- Snow Means Death: It starts snowing just as Naomi lets down her guard enough to reveal her real name to Light, who sentences her to suicide. The snow continues as she walks to her fate.
- The Stoic: Her emotional strength rating is a full 10/10.
- Too Dumb to Live: On one hand, she doesn't seem to realise that a creepy kid following her around asking Have You Told Anyone Else? is a bit off, not to mention the Plot-Induced Stupidity and Idiot Ball. On the other hand, it was a Contrived Coincidence that she went to the police station when Light was there and L wasn't, Light's trustworthiness is backed up by another person and he comes off as a genuine member of L's team. Regardless of what side you're on, nearly all fans agree her death was pretty cheap.
- Subverted in the live action film, wherein her role is notably expanded from the manga. She still dies, but it's more plausible and makes Naomi seem less like an idiot.
- Tsundere: This is Lampshaded in Another Note.
- Vasquez Always Dies: One of the most Badass female characters on the show, as well as the first to die.
- We Hardly Knew Ye: Dies too early in the manga to really establish her personality, but this was fixed in the prequel novel and the movies.
Voiced by: Hideo Ishikawa (JP), Michael Adamthwaite (EN), Pedro Molina (Spain), Gerardo Vásquez (Latin America)The FBI Agent who was tailing Light.
- Adaptation Name Change: Known as "Raye Iwamatsu" in the live action movie, though pretty much everything else about the character is the same. Made into a plot point in the live action TV series, where his real name is Mark Dwellton, with "Raye Penber" being an alias.
- But Not Too Foreign: Although American, he is of Japanese descent.
- Christianity Is Catholic: Raye is a devout Catholic in the live action movie.
- Gray Eyes: Of the innocent meaning.
- Incredibly Obvious Tail: Ryuk is the first to mention, and bring the reader's attention, to Raye tailing Light, though Light admits he knew already that he was being tailed. Well Raye does not blend in well in Japan with his longcoat.
- It's Probably Nothing: His reaction to Naomi's concerns about the busjacking.
- Mauve Shirt: Gets fleshed out despite only appearing in a few episodes.
- Morton's Fork: Follow my instructions or I kill you and your girlfriend. Guess what happens anyway.
- Retirony: Light begins his plan to kill Raye the day he had decided would be his last day trailing Light, as he clearly could not be Kira.
- Spanner in the Works: Completely unintentional on his end but Light's biggest mistake in the series was his murder of Penber. Had he allowed Ray Penber to live, all suspicion of Light would have been dropped.
- Stay in the Kitchen: To Naomi, telling her that her suspicions are obsolete now, since she quit her FBI job when they got engaged. Needless to say, he should have listened to her.
- Tall, Dark and Handsome: Fits the description perfectly.
- Too Dumb to Live: He makes Matsuda look like a genius in comparison. First he shows his ID to the suspect he's tailing, then blows off Naomi's perfectly valid concerns about the incident. This gets him, his coworkers, and fiancé killed.
- Unwitting Pawn: Ha-ha-ha-ha-ha-ha, made you kill your coworkers.
- Zombie Infectee: Rather than acting completely Genre Blind, Raye acts like this about showing his name to a Kira suspect in the live-action movie.
Voiced by: Maaya Sakamoto (JP), Heather Doerksen (EN), Graciela Molina (Spain), Carmen Calvell (Spain, movies), Toni Rodríguez (Latin America)A popular and pretty young woman whom Mikami chose to be Kira's spokesperson. She was the girl whom Light briefly dated once to hide his connections with Misa; the authors later "forgot" about her... and once they recalled her, they brought her back. Light gets in contact with her to gain access to Mikami, seducing her with a promise to make her the goddess of the New World. Eventually, Mello kidnaps her, and then Mikami kills her - Light would have killed her, if Mikami hadn't done it first - after she kills Mello to prevent any evidence from being gotten from her.
- Alpha Bitch: "Refined Takada" is the mean girl to Misa.
- Though technically, Misa herself started the whole fight by threatening to "break her knee" (leading to Halle having to restrain her). Later on, Takada manages to keep her cool in the restaurant while Misa immaturely and outlandishly brags that Light will marry her, leaving Takada to feign being hurt and leave with her head high. This is toned down in the anime, which has both women keeping their composure at the table and Misa's bragging being less over-the-top, although Misa chugging down a bottle of wine afterwards is still kept (to portray the differences between the composed Takada and the wild Misa).
- Still, Kiyomi seems to enjoy rubbing her affair with Light in Misa's face in her own subtle way. She is the one who approaches Misa with the dinner invitation just for that very purpose.
- Alternate Continuity: In the live action movies she fulfills the same role as the Yotsuba group does in the manga / anime.
- Ambition Is Evil: While she is genuinely attracted to Light, she becomes much more interested in being close to him after learning that he's Kira.
- Ax-Crazy: In the live-action film adaptation.
- The Beard: Light sets it up so that he "dates" her. His excuse for the Taskforce is that Kira will not kill Takada's boyfriend and that this will keep him safe while he investigates Kiyomi, but the real reason he does it is because he is Kira and he needs Takada to access Mikami.
- Betty and Veronica: The Veronica to Misa's Betty for Light's Archie.
- Bitch in Sheep's Clothing: Definitely. She sleeps with a man and invites his fiancee out to brag about it, while being presented to the world as the epitome of grace and class. Even her nickname is "Refined Takada".
- Blatant Lies: Her repeated referral to Misa as her "good friend", even after this exchange:Misa: Are you going to get Kira to kill me?Takada: Of course not!
- That line itself is another blatant lie.
- Bodyguard Betrayal: Directed by Halle into being kidnapped by Mello.
- Break the Haughty: Her very last scene. The woman who spent all of her time being presented as superior, poised, and perfect dies naked, crying, and reaching out for comfort.
- Chekhov's Gunman: Shows up as a very minor character in the first arc, promptly vanishes, and is never mentioned again until far into the second arc.
- High School Sweethearts: College Sweethearts with Light.
- The Dark Chick: On Team Kira.
- Deadly Upgrade: She makes the eye deal in the live action movie.
- Ditzy Genius: As lampshaded by Near, she gets very good grades in school but is lacking in the common sense department.
- Driven to Suicide: Under the influence of Light's Death Note.
- Dude Magnet: Quite popular with the opposite sex.
- Horrible Judge of Character: She trusts Light, after he tells her that he is Kira - the same Kira who has murdered anyone who got or threatened to get in his way. She even expects him to save her.
- Hot Scoop: She becomes Kira's spokeswoman on the NHN TV station. Her beauty and poise make her very popular with viewers.
- Intellectually Supported Tyranny: As an educated young woman, rather than help protect society against the cult of Kira, she becomes one of its main propagandists. "We must teach our children that Kira is good."
- It's All About Me: She loves to be the center of attention.
- Knight Templar: Blinded by ideals, check. Devoted, check.
- Lady Macbeth: She urges Light to kill Misa at one point.
- Loves My Alter Ego: Subverted; while she is very much more in love with Kira, she's still attracted to Light.
- Meaningful Name: Takada = tall ricefield; Kiyomi = pure beauty. Notable in being the only character in the entire series to have a real-life name.
- Modesty Bedsheet: Wears one right after killing Mello, who had stripped her naked.
- Murder the Hypotenuse: Really dislikes Misa and tells Light at least once to kill her.
- Namedar: She makes the eye deal in the live action movie.
- No Place for Me There: In the live action movies "There's so much filth in the world... and I am the worst of all."
- The Ojou: She's nicknamed "Refined Takada".
- Principles Zealot: More in the live action. In the anime, she's more interested in being Kira's goddess than in his ideals.
- Psychotic Love Triangle: She and Misa are rivals for Light's heart, which ends just as well as you'd think it would.
- Serial-Killer Killer: As Kira's "goddess"
- Ship Tease: With Light and Mikami. The dialogue in the Relight 2 special seemed to suggest she is dating both of them.
- Unequal Pairing: Considering Light's god complex, this is pretty much unavoidable.
- Victoria's Secret Compartment: Keeps a page of the Death Note in her bra.
- Who's Laughing Now?: In the live action movie.
- Yandere: After Light assures Takada that his seeing Misa doesn't mean anything and "you're the only one for me":Takada: If you're lying you're going to pay. I'll tell Kira, you know.
Light: Ha ha. Great joke Takada.
Takada: I'm not joking.
Ide: Whoa, women are scary.
- Woman On Fire: How she ends up. Fortunately, she doesn't seem to be conscious for most of it, at least not in the anime.
- You Have Outlived Your Usefulness: Shortly after she kills Mello, Light tells her that before he lets her die in order to avoid having her picked up and questioned.
Voiced by: Miki Nagasawa (JP), Venus Terzo (EN), Graciela Molina (Spain), Nallely Solís (Latin America)A thief L hires to assist in infiltrating Yotsuba. Her real name is Mary Kenwood.
- Anti-Hero: She is a professional catburglar under the employment of L.
- Biker Babe: Weaponized by Light. In the anime version she seems to suffer a heart attack while driving her motorcycle, only crashing after dying.
- Classy Cat-Burglar: Word of God say that Wedy has the "stereotypical female spy look".
- Cool Shades: She wears sunglasses.
- Highly Visible Ninja: Bright PINK!
- Ice Queen: The How to Read Volume rates her "Bitchiness" at 10/10. Although in the US translation, it's read as "Sex Appeal."
- Spell My Name with an "S": In the anime, when we see her real name written down by Light when he's killing her with the Death Note, her first name is spelled "Merrie" and not Mary.
Voiced by: Takuya Kirimoto (JP), David Orth (EN), Daniel Del Roble (Latin America)A Con Man L hires to assist in infiltrating Yotsuba.
- Affably Evil: Criminal activities aside, he's a decent guy.
- Alternate Continuity: Although Light kills him with the Death Note in both the manga and the anime, the cause of death is different in each continuity: liver cancer in the manga, a heart attack in the anime.
- Anti-Hero: A self-admitted con artist who's brought in to stop Kira.
- Boxed Crook: According to the manga, he works for L because he has enough on him to send him away for life.
- Doesn't Like Guns: But he knows how to use them if really necessary.
Kyosuke Higuchi/3rd Kira
Voiced by: Issei Futamata (JP), Andrew Kavadas (EN), Ricky Coello (Spain), Oscar Gómez (Latin America)The third Kira and the main antagonist of the Yotsuba arc. He's one of the eight-member Yotsuba board and head of the technological development, but isn't very competent compared to the others, and is obsessed with gaining social status in addition to wealth. Light gave the Death Note to Rem to clear himself and Misa of suspicion. Rem gave it to Higuchi because he would likely use it the way they needed him to. After his arrest, Light kills him to regain control of the notebook.
- Ambition Is Evil: Desires promotion and financial success and is prepared to kill to get it.
- Arc Villain: Serves as a Big Bad stand-in during the Yotsuba storyline.
- Asshole Victim: He's enough of a jerk that Rem actually prefers Light over him. Then Light kills him using the Death Note, to no one's grief.
- Axe Crazy: By the time the Task Force is closing in, Higuchi is a ranting madman.
- Big Bad Wannabe: He thinks having the Death Note will put the business world at his mercy but he's really just a pawn in Light's schemes and is easily killed off once his part in the real villain's plan is done.
- Corrupt Corporate Executive: Sits on the Yotsuba board and has no problem committing murder to climb the ranks.
- Curb-Stomp Battle: Really, he didn't stand a chance against L and Light's scheming.
- The Friend Nobody Likes: He often shows his arrogance despite being not as competent and smart as six of the other seven members, leading him to be disliked by his co-workers. Namikawa, Mido and Shimura conclude from his bad personality that he is the Kira among them. They are right.
- From Nobody to Nightmare: An unpopular corporate drone before Rem handed him the Death Note.
- Greed: Higuchi is mainly concerned with profit.
- Hate Sink: He's certainly no more evil than Light, but he has neither Light's charm nor any Well-Intentioned Extremist tendencies to make him sympathetic. His overbearing personality and overwhelming selfishness and greed serve to make the audience loathe him.
- I Have You Now, My Pretty: Tries to force Misa to marry him when she was investigating his corporation.
- Jack the Ripoff: The Third "Kira".
- The Killer Becomes the Killed: He acts as the third Kira as a part of Light's Memory Gambit, and was finally killed when Light regains his memories of the Death Note.
- Namedar: When cornered, he makes the eye deal.
- Quick Draw: When confronted by Task Force members at Yotsuba headquarters, Higuchi pulls a pistol and hits Mr. Yagami, despite Wedy having her own gun trained on him the entire time.
- Serial-Killer Killer: The third Kira, thanks to Light giving him the Death Note as part of a Batman Gambit.
- A Sinister Clue: Left-handed.
- Slasher Smile: Makes an incredibly unnerving and evil smile while writing down names, and after making the eye deal.
- Smug Snake: Enjoys insulting people despite his limited abilities.
- Stop, or I Shoot Myself!: Tries to pull on this when the SPK was about to arrest him.
- Too Dumb to Live: Was tricked by Misa of all people into revealing himself as Kira.
- Unwitting Pawn: Only gets to become Kira as a part of Light's Memory Gambit. Light kills him when he's outlived his usefulness.
- Villainous Breakdown: Loses composure more and more as he gets closer to being arrested.
Voiced by: Hirofumi Nojima (JP), Ted Cole (EN), Xavier Fernández (Spain), Luis Alfonzo Mendoza (Latin America)A member of the Yotsuba Eight.
- Bishōnen: Of all the members of the Yotsuba group, he's the only one drawn in an appealing manner.
- Blood from the Mouth: Pukes blood when Light kills him.
- Board to Death: Like the rest of the Yotsuba group he's killed by Light.
- Color-Coded for Your Convenience: Official color seems to be purple.
- Corrupt Corporate Executive: A member of the Yotsuba Group, and perfectly willing to profit from the deaths of others.
- Evil Genius: He's the real brains of the Yotsuba Group, is smart enough to work out on his own which of his fellow board members if the Third Kira, and even successfully manipulates Light during a phone conversation. Even L and Light acknowledge how smart he is, deducing that he can't be the Third Kira because he wouldn't need the assistance of the rest of the board.
- Hazy Feel Turn: Which side he's really on at the time of his death is pretty ambiguous.
- Heel–Face Door-Slam: He, along with two other members of the Yotsuba board, wanted out, but were killed by Light regardless.
- Manipulative Bastard: Managed to manipulate Light of all people into revealing Higuchi as the third Kira—though he himself had already worked it out.
- The Proud Elite: He is cold, calculating, and very intelligent. He is also quite attractive.
- Smart People Play Chess: According to How to Read 13 he's an expert chess player.
- Tall, Dark and Snarky: Tall, black haired, and sarcastic.
- Unwitting Pawn: Averted. Namikawa knows full well that he's a pawn of whoever the real Kira is, and just wants out.
- Villainous Friendship: With Midou and Shimura.
- You Have Outlived Your Usefulness: Light kills him and the remaining members of the Yotsuba group when the whole ordeal with Higuchi is over.
- You Just Told Me: How he figures out that Higuchi is the third Kira.
Voiced by: Tomohiro Nishimura (JP), Drew Nelson (EN), Miguel Ángel Ruíz (Latin America)Mello's henchman, and a fellow graduate of Wammy's House.
- Adaptation Dye-Job: His hair and eye colors were not defined in the manga for a very long time. Fanon decided his hair was a bright red and his eyes were green. The anime (and later a colorized manga publication) presented his hair as being brown (though it looked a bit green depending on the lighting), and his eye color as blue. In one of the video games, his hair was a light blue, and his eye color could not be discerned. And on a trading card, his hair was a straight-up green. (This possibly makes Matt the Trope Codifier.)
- Adapted Out: Because in the drama Mello is merely a Split Personality of Near or, alternatively, does not actually exist, Matt does not appear in the drama, as there was no reason for him to.
- Attention Deficit... Ooh, Shiny!: Easily distracted. See "idiot ball."
- Badass Bookworm: Like most of the Wammy's boys he's a scrawny geek who doesn't appear to be in very good shape. Also like them he proves a royal pain in the backside for Light. However, he attacks an armed convoy alone and nearly gets away.
- Badass Driver: Matt leads Takada's guards on a merry chase through Tokyo.
- Beware the Nice Ones: Oh, yes. Special mention goes to the German manga translation, where it's implied that he beat up the delivery guy that helped Misa and Mogi sneak out, rather than just talking to him.
- Bishounen: When he takes his goggles off...which never actually happens in-series, but is shown in some concept drawings from ''How to Read: 13''.
- Brilliant, but Lazy: Would rather be playing video games than doing just about anything else. He doesn't even like to go outside!
- Cigarette of Anxiety: His habit in general, and in particular the cigarette he lights during the Takada mission, which turns out to be his last.
- Cloud Cuckoolanders Minder: Word of God says he has one in the form of Mello. However, given that Matt seems to be much more even-tempered and level-headed than Mello, it's likely that Matt is Mello's minder as well.
- Cool Car: Drives a 1968 Chevy Camaro in the manga. (In the anime, it's been changed to a 1968 Plymouth Road Runner 383 with a taillight panel from a 1969 Dodge Coronet 440.)
- Cyberpunk: Has this style in his clothes, and his sofa.
- Deadpan Snarker: His two canon lines in the anime are pretty snarkynote .
- Drives Like Crazy: The Chase Scene was pretty much his only scene.
- Early-Bird Cameo: In the manga, he appears at Wammy's, listening to L answer the kids' questions from his computer. In the Relight Special, he is replaced by someone who looks a lot like L, and is thought to be Beyond Birthday.
- Easily Forgiven: When he accidentally loses track of Misa and Mogi, Mello isn't happy about it, but doesn't even so much as scream at Matt, when it's implied that others might have been killed for less.
- Excuse Me While I Multitask: Plays a game while spying on Misa, and monitors several screens (plus an audio feed) at once.
- Extreme Doormat: To Mello.
- This is subverted, though. He calls Mello up to complain about being bored while spying on Misa and Mogi. Mello, for his part, tells him to get back to work, but doesn't yell at him or anything.
- Everyman: Arguably one of the most normal characters, and one of the most relatable to the audience.
- Famous Last Words: "You won't shoot..." Also qualifies as Tempting Fate.
- Goggles Do Nothing: Is never seen without his goggles on, except in one tiny concept drawing in How to Read: 13.
- Hacker Cave: The dingy little apartment he shares with Mello.
- Heterosexual Life-Partners: Almost always portrayed this way with Mello by fandom.
- I Surrender, Suckers: If you look very closely at his hand during his confrontation with Takada's guards, he was going for a gun when they fired at him.
- Idiot Ball: Loses his focus, and totally misses Misa and Mogi escaping.
- Informed Ability: We're told he was number three at Wammy's, just behind Mello and Near but we don't see it in action.
- Killed Mid-Sentence: "You won't shoot..."
- Mauve Shirt: Gets just enough characterization for his death to be sad.
- Megane: A variation with goggles instead of glasses. It's unknown if the goggles are meant to be a substitute for conventional frames, or if the lenses are actually corrective lenses, though.
- Men Can't Keep House: Justified on the grounds that he cares far more about video games than cleaning. Mello, surprisingly, doesn't seem to mind too much.
- Morality Pet: For Mello.
- Must Have Nicotine: He's mentioned to be a chain-smoker and is never shown without one in his mouth.
- No Kill Like Overkill: Was shot approximately 50,000 times!
- O.C. Stand-in: He does have a character/personality (Word of God at least, although his function is just to give Mello someone to play off), but his screen-time is so short you don't see enough of it to stop the fans from using every single interpretation possible whatever way they like (more OC Free for All).
- Odd Name Out / Special Person, Normal Name: Of the Wammy's boys. You got L, Beyond, Mello, Near, and... Matt.
- Only Friend: The only person he ever really interacts with In-Universe is Mello.
- Only Sane Man: Is the only Wammy's kid (apart from Linda) with a relatively normal personality. Also, not surprisingly, he plays this role a lot in fanfictions to more...dysfunctional characters such as Mello.
- Oral Fixation: Always has a cigarette in his mouth.
- Parental Abandonment: Like all the other kids at the house, he's an orphan.
- The Pirates Who Don't Do Anything: He plays video games and he smokes... a lot. Considering that Wammy's House seems to exclusively rear genius eccentrics, the odds are good that that's his particular eccentricity (or addiction, depending on what you view of what L's sweet-devouring, Near's toy-obsession, and Mello's chocolate-violence as).
- Real Men Wear Pink: His shirt is sometimes portrayed as having pink and black stripes, though it could actually be just the way the light was hitting it.
- Refusal of the Call: It's hinted that he could have surpassed both Mello and Near and become L's successor, but that he chose not to, preferring to stay in third place and work alongside Mello. note
- Satellite Character: He's mostly just there so Mello has someone to interact with.
- Sidekick: To Mello.
- Smoking Is Cool: Is shown conspicuously lighting a cigarette (that would turn out to be his last) while driving a classic car into battle.
- The Slacker: Implied.
- The Southpaw: Is left-handed.
- Sunglasses at Night: Wears his tinted goggles even while indoors, in a very poorly-lit room.
- Talking Your Way Out: Attempts this. It does not work.
- Techno Wizard: He's apparently great with electronics, though we don't see much of that unless he's with a video game.
- Teen Genius: He's the third most talented member of Wammy's House. Yes, Matt was third in line to be L after Near and Mello.
- The Peeping Tom: Enjoys getting to watch Misa 24/7, whom he calls "cute."
- Trash of the Titans: His apartment is littered with snack food wrappers and cereal boxes.
- Undying Loyalty: To Mello.
- Unfazed Everyman: Knows nothing about Shinigami or killer notebooks, but goes along for the ride when Mello chases after Kira.
- Video Game Culture: One of his few appearances shows him playing a video game and it's mentioned on his character page in How to Read 13 that he enjoys video games.
- What, Exactly, Is His Job?: He is most likely employed somehow when we first see him note , since he's got food and a roof over his head, and has some luxury items, but we never see what he does for a living. He is thought to be a professional hacker (legal or otherwise), though this is not confirmed In-Universe. When we first see him, he's just sitting there playing video games, and in all his later appearances, he's doing recon work for Mello.
- We Hardly Knew Ye: He only appeared in a few panels before getting killed.
- You Gotta Have Blue Hair: In one of the games.
Voiced by: Chafurin (JP), Ward Perry (EN), Vicente Gil (Spain), J. Ignacio Latorre (Spain, movies), Leonardo García (Latin America)Demegawa is director of Sakura TV, a Japanese news channel that is notoriously unreliable, and he shamelessly seeks to exploit the Kira case. He is first seen attempting to broadcast the video tapes Misa sends to his network to get Kira's attention, although Soichiro puts a stop to that. After the Time Skip, he becomes Kira's supporter and self-appointed spokesman, creating and hosting the Show Within a Show Kira's Kingdom...until the incident mentioned below in You Have Failed Me.
- Adaptation Name Change: His name is Yuji in the second live-action film.

- Attention Whore: Demigawa wants all eyes on him and is prepared to side with Kira to get it.
- Fat Bastard: Overweight and a self-centred jackass.

- Karma Houdini: In the Live Action movies, he does not get any retribution for his Jerk Ass attitude.
- Mouth of Sauron: Relays Light's messages to the public.
- Meaningful Name: Actually a case of an ironic one; his given name is written with a kanji character meaning "benevolence."
- His surname, on the other hand, is reminiscent of the English "demagogue", which describes him perfectly.
- Only in It for the Money: All he cares about his profits.
- Politically Incorrect Villain: In the second film, wherein he sexually harasses Takada.
- Spared by the Adaptation: He doesn't die in the second live action film.
- You Have Failed Me: Killed by Mikami for falling for Near's money bait rather than pointing his cameras at Near so Misa could have killed the SPK members as Light wanted, although also because he was being too much of a loose cannon in general.

Light's school pal.
- Adjusting Your Glasses: The nose bridge push, see picture above.
- Black Shirt: Light seems to see him as such when he and the other unnamed friend are talking about Kira with Fan Boy-like enthusiasm. They suggest that Kira is a superhero and Light is the one to correct them when they argue that because of Kira the crime rate has gone down, pointing out that since the Kira killings are seen as homicides than the crime rate has actually gone up.
- Fanboy: Either he or the other unnamed friend was a fan of the X-Men.

The boss of The Mafia that works with Mello.
- Bad Boss : Has two of his men executed, one for theft and one for failure.
- Dragon-in-Chief: He's the boss of The Mafia. But he defers to Mello's plans because it's good business.
- Gonk: Bears little resemblance to the rest of the cast.
- Informed Attribute: Word of God names him as "the most evil" in the cast. However, while we get to see him do some bad things, we never get to see him do anything that would make him stick out as particularly evil in comparison to the other characters. He gets overshadowed by Light.
- Karmic Death: He and most of the other mafiosi are killed by Kira when the Taskforce raids their hideout.
- The Mafia: At least nominally, he's his particular faction's leader. He always defers to Mello, though, because it's good for business.

Misa's stalker, given a name in the live action movies. Killed by Gelus.

Voiced by: Ami Koshimizu (JP), Lalainia Lindbjerg (EN), Elisa Beuter (Spain), Nallely Solís (Latin America)A girl that Light asks out on a date to Spaceland as part of his plan to get Raye Penber's name.
- Clingy Jealous Girl: "I've got you all to myself!" Also, in the manga, she insists that she and Light still go to Spaceland after witnessing a gruesome death.
A famous teen idol and pop star that Sayu fangirls over.
- Brainless Beauty: It's remarked that he could never get into To-Oh university (a fictional version of the prestigious University of Tokyo).
- Chekhov's Gun:His name, not the character, which is used by L when he disguises himself as a student at Light's university.
- Identical Stranger: It was pointed out that in the manga he kinda looks like L.
- Idol Singer: Basically the extent of his character, he is a famous pop icon.
- Ship Tease: With Misa. Misa looks very stunned when they're acting out a romance scene together but then suddenly objects to kissing him informing all that she already has a boyfriend.
- Unwitting Pawn: To L, in a way. L uses his name, "Hideki Ryuuga", as an alias when he disguises himself as a university student. Even if Light tries to kill his classmate Hideki Ryuuga, the pop idol is so famous that Light can't guarantee he won't accidentally picture his face instead, so if the real Ryuuga dies, then Light is definitely Kira. Light doesn't do it.
Misa's original manager.
- Bad Boss: Towards Misa. She is very scary, pushy, and controlling.
- Corrupt Corporate Executive: Maybe. L allegedly has her arrested for drug possession offscreen in order to hide the fact that he's detaining Misa from the general public. The show never goes into detail on whether L planted the evidence or not or even if she was really arrested and not just paid off.
- Horrifying the Horror: Misa, the Second Kira, is very intimidated by her and even L and Kira seem a bit unnerved.
- No Sense of Personal Space: She literally grabs Misa by the wrist and pulls her off to work.

A news anchor for NHN. Seen in one scene in Episode 11, where he denounces Kira's actions on live television.
- Did You Just Flip Off Cthulhu?: Calls out Kira's actions as a threat to the nation's constitution and praises the police for standing up to him, with his face on live TV. He then gives his full name, knowing full well that he's just given Kira the ability to kill him. Kira doesn't.
- Nerves of Steel}: Not a fighter, but he fits the "Brass Balls" version of the trope. He's one of the bravest characters in the show, and willing to lay down his life for a point of principle.
