[[quoteright:250:https://static.tvtropes.org/pmwiki/pub/images/yumeji_fujiwara_19928.jpg]]

A fairly average guy, except that he has the power to see into people's dreams. His encounter with the mysterious Merry Nightmare changes that, and he vows to be her companion and to help her find her way back to the world of dreams. It's hinted that he and Merry have met somewhere before, and because of his abilities and potential, Chaser John Doe speculates that [[spoiler:he may be NotQuiteHuman]].
----
* AccidentalPervert: Frequently.
* AcheyScars[=/=]ImHavingSoulPains: Often his right-hand hurts when he leaves a Dream Demon's Daydream. [[spoiler:It also hurts when Kyou uses his powers.]]
* AmbiguouslyHuman: It's implied that he might be something other than human.
* AuraVision: He can see what dreams people experience with his [[SpecialOddHand right hand]] by looking at the color surrounding them.
* ChickMagnet: To start, he has the obvious affection of [[PatientChildhoodLoveInterest Isana]], there is a lot of ShipTease between him and Merry, and there are some mild hints that Yui might like him as well.
* ChronicHeroSyndrome
* CurtainsMatchTheWindow
* DittoFighter: [[spoiler:"Lucid Install" allows Yumeji to actually become the Dream Demon's themselves, instead of merely transferring their power into him. His causes his body and appearance to physically transform into the dream demon, not only allowing him to use any of their powers but even grants him the same strength, status and skills that they have.]]
* FanBoy: Of {{Toku}}.
* FusionDance: [[spoiler:"Ultra Lucid Gadget" lets him take a Dream Demon into himself and fully access their power and change his appearance to look like the Dream Demon.]]
** [[spoiler:"Chaser": In addition to John Doe's saw-guillotine, he also gains the belt and cape. He also gets John's mask with ears on the side of his head and his shirt gains a stripe on his right side. Yumeji gains the power of SuperSpeed.]]
* HalfHumanHybrid: Hinted to be this [[spoiler:but is really a case of TouchedByVorlons]].
* HeartIsAnAwesomePower: Seeing into people's dreams is actually incredibly useful.
* HeroicBSOD: He gets hit with this after he finds out that [[spoiler:Hercules' vessel is his best friend ''right'' as Hercules takes over Takateru's mind and body completely. And the only reason Hercules had enough time to do that was because Yumeji promised Takateru that he wouldn't use his 'dream vision' since it made Takateru uncomfortable.]]
* IOweYouMyLife: His original reason for staying with Merry.
* IdiotHair: Even though he's not especially stupid.
* {{Invocation}}: Uses the titles of Dream Demons he's met when using Lucid Gadget.
-->'''Yumeji:''' "I'll borrow it, <Insert power's name>!"
--> or "Lend me your power, <Insert power's name>!"
* TheLancer: He's not a potent enough combatant to be TheHero, but he can provide excellent support.
* LivingEmotionalCrutch: Again, to Merry.
* MegaManning: His "Lucid Gadget" ability allows him to replicate the powers of Dream Demons he's previously met. Actually, Yumeji isn't actually recreating their powers in the literal sense, he simply lacks the imagination to create anything original.
** "Chaser": Replicates the saw-guillotine sword that John Doe wields.
** "Loneliness": Replicates the giant kokeshi Ichima uses. It can be launched or dropped from nearly every angle.
** "Lovers": Replicates Chris Evergreen's right hand that can be used as a RocketPunch.
** "Chain": Replicates Noir's chain.
** "Maze": Replicates Landsborough's mechanical clown minion.
** "Familiar": Yumeji [[TwinMaker makes a clone of himself]] like Legion.
** "Maestro": Replicates a {{hand puppet}} that can [[SonicStunner conduct loud music]] like what the Achtelnote twins use.
** "Pharos": Alters the daydream of a Dream Demon. %%Actually have no idea exactly what it does so correct/replace this when someone does know.%%
** "Hunter": Replicates the weapon wielded by Ren when he fuses with Quartier Latin. Yumeji's Idiot hair also changes to look like a lightning bolt.
** "Garden": Replicates one of Engi's Sannasubi swords.
** "Ice Wall": Replicates Hrimthurs' ice.
* MostWritersAreWriters: Part of the Writing Club. He actually met John and his cat minions in the beginning during his WritersBlock in August.
* MyGodWhatHaveIDone: By keeping his promise to his friend, [[spoiler:[[NoGoodDeedGoesUnpunished he allowed said friend to be completely consumed]] by the BigBad. Needless to say, he doesn't take this revelation well.]]
* OrdinaryHighSchoolStudent: Well not including his 'dream vision' ability.
* SpecialOddHand: Yumeji can see the color of what the person will dream by making a circle with his thumb and index finger of his right hand and looking through it. He has also the ability in daydreams [[spoiler:and eventually the real world]] to create weapons or replicate abilities he has seen with his right hand.
* TookALevelInBadass:
** With his Lucid Gadget ability.
** [[spoiler:Gets another one when he used Lucid Gadget in the real world and then Ultra Lucid Gadget.]]

->Voiced by: Creator/AyaneSakura (JP), Creator/HilaryHaag (EN)
[[quoteright:250:https://static.tvtropes.org/pmwiki/pub/images/merry_nightmare_19926.jpg]]

Merry Nightmare is a Dream Demon with severe amnesia. She knows who and what she is (she's a Dream Demon, and for some reason a very powerful one), but she doesn't know how she got from the dreamworld to our world, or why she's stuck here. She is unlike others because she has her own manifestation in the human world. Her only hope of finding a way home is to hunt down other Dream Demons in our world and to find them she needs Yumeji's help. Yumeji has labeled her with the title "Yumekui Merry," or Dream Eater Merry.
----
%%* ActionGirl
* AdaptationDyeJob: On the manga covers, her hair seems to be dark indigo, but the anime changes it to more of a burgundy.
** Curiously, this doesn't just apply to her hair; there's no real indication of this in the original art, but the animators make Merry's ''skin'' slightly pinker than everyone else's.
* AnimalMotifs: Sheep, frequently {{lampshade|Hanging}}d.
* BadassAdorable: She's pretty damn cute for a demon, but don't let her petite body and stunning looks fool you, she's one hell of a powerful girl.
* BareFistedMonk: Fights with fisticuffs, in comparison to every other character.
* BareYourMidriff: ''Constantly.'' The anime even treats it as FanService -- instead of {{Panty Shot}}s, we get gratuitous closeups of Merry's bellybutton.
** Subverted in the beach episode; Merry doesn't own a swimsuit, and the one Isana lends her is her old one-piece from school.
* BarrierMaiden: Merry IS part of [[spoiler:the system that keeps the dream world separate from ours. Her getting stuck in our world is one of the things that allowed Heracles to rise to power.]]
* BerserkButton: Don't ever hurt her friends, ''especially'' Yumeji.
* BettyAndVeronica: The Veronica to Isana's Betty.
* CatchPhrase: "I have no hopes or dreams."
* ChestInsignia: Arguably the symbol on her camisole top is a stylized Z with the top line going all the way around.
* CuteBruiser: John actually [[LampshadeHanging wonders aloud]] how she can get so much power out of such a small body.
* CuteLittleFangs: She has them.
* CuteMonsterGirl: Being a female Dream Demon.
* DangerouslyShortSkirt: Never gets a PantyShot, but she's still every bit as tough as the average ActionGirl.
* DarkIsNotEvil: Is a Dream Demon, but without a doubt, she is on our side.
* DoesNotLikeSpam: Dislikes carbonated drinks.
** [[spoiler: Ironically, chapter 99 reveals that she was really excited and wanted to try cola when Yumeji first explained it to her.]]
* ExoticEyeDesigns: Her pupils are [[HellishPupils horizontal rectangles]].
* {{Expy}}: Possibly inspired by [[Franchise/TouhouProject Maribel "Merry" Hearn]].
* FacialMarkings: Two little purple triangles, one under each eye.
* GamerChick: She enjoys playing video games.
* GetAHoldOfYourselfMan: Does this after Yumeji starts blaming himself for [[spoiler:Takateru's mind being completely consumed by Hercules.]]
* HeartbrokenBadass: When one misunderstanding almost gets Yumeji killed via [[TakingTheBullet Taking the Sword]], Merry's rage is sufficient to cause her to [[TookALevelInBadass take a level in badass]] ''right then and there''.
* TheHero: Mostly by default, but she's pretty well-suited to the role.
* InSeriesNickname: [[CharacterTitle Yumekui Merry]], of course.
* ImpossiblyCoolClothes: Her coat's coattails are somehow always curled.
%%* LightningBruiser
* MaleGaze: As noted above, she has a lot of shots focusing on her exposed stomach.
* [[ManicPixieDreamGirl Manic Pixie]] [[StealthPun Dream]] [[ManicPixieDreamGirl Girl]]: She definitely manages to make Yumeji's life more interesting, although he wasn't an OrdinaryHighSchoolStudent to begin with.
* {{Meido}}: Her work clothes.
* MonsterRoommate: Since she doesn't have a place of her own, staying with Yumeji and Isana is the obvious solution.
* MsFanservice: She can play this off good, due to her good looks, and BareYourMidriff & MaleGaze shots.
* NiceHat: She almost never takes it off -- which is only to be expected, considering she was created by an author who used to be best known for ''Franchise/TouhouProject'' doujinshi.
* NiceShoes: Merry wears slip-on shoes with a closed eye sigil design on the toe box of each one.
* PointyEars: Has them but are often hidden.
* SecurityBlanket: In the first episode, she misplaces her hat, panics, and stumbles away from Yumeji mumbling [[MadnessMantra "My hat, my hat, where's my hat..."]] When she later recovers it, she explains that she's just not comfortable without a hat on.
* SheFu: How she fights.
* ShesGotLegs: Her legs are accentuated by her DangerouslyShortSkirt and her [[ZettaiRyouiki thigh high stockings]].
* SigilSpam: Her [[ImpossiblyCoolClothes jacket]], [[NiceHat hat]], and [[NiceShoes shoes]] have the symbol that is like the top arch on the Gate. It looks like a closed eye.
* {{Stripperiffic}}: Indeed. Her attire includes clothes such as a top which leaves most of her stomach exposed, a short skirt that displays her legs rather nicely, and of course the obligatory thigh-high stockings. Which makes it quite amusing on h
* SuperOCD: [[spoiler: Had a case of this back when she worked as the Gatekeeper. As she kept a massive pile of keys in a certain order, placement and location and after Yumeji messed them up she quickly put them back the way they were.]]
* SuperToughness: Dream Demons can be hurt, but they -- especially Merry -- can take a lot more punishment than ordinary humans. For example, there's a scene in the manga, where Merry, Yumeji, and a few others have stumbled into Maze's dream space, that involves Yumeji about to be hit by a [[ItMakesSenseInContext robotic clown wielding a giant sledgehammer]]; Merry leaps in, takes the hit for him, and proceeds to beat the robot into scrap while shouting "[[PunctuatedForEmphasis THAT...]] '''HURT!!'''"
* TookALevelInBadass: Once she remembered [[spoiler:her role as "Sheep", the gatekeeper of the "Gate".]]
* TrademarkFavoriteFood: Donuts. She ''adores'' them.
** [[DoesNotLikeSpam Trademark Least Favorite Food]]: She can't handle carbonated drinks.
* WhatIsThisThingYouCallLove: Claims not to understand love and other such human emotions.
** That said, after having been asked whether or not she liked Yumeji by Isana (prompting the above claim), she begins to list all of [[http://www.mangareader.net/yumekui-merry/34/12 Yumeji's good qualities and how important he is to her,]] prompting Isana to muse that Merry's feelings are [[http://www.mangareader.net/yumekui-merry/34/14 "liking someone."]]

[[quoteright:250:https://static.tvtropes.org/pmwiki/pub/images/isana_tachibana_19934.jpg]]

Isana is a childhood friend of Yumeji's, a member of the Art Club, and harbors strong feelings for him. She lives with her father and works at the family-owned MaidCafe, STO Cafe. She quickly befriends Merry, and it is hinted that she and Yumeji met her at some point in their childhood.
----
* AdaptationDyeJob: In the manga, her hair is purple-tinted; the anime turns it white.
* BettyAndVeronica: The Betty to Merry's Veronica.
* TheChick: Shares this position with Yui.
* ChildhoodFriendRomance: To Yumeji.
* GirlishPigtails: Has them when she uses hair ties.
* HollywoodPudgy: Invoked. She's very insecure about her weight, and occasionally teased about that insecurity, but she still looks cute and petite to the audience and none of the other characters seem to actually care.
** Chapter 39 takes this to another level.
* IdiotHair: Like Yumeji, she's not particularly stupid, just not a genius.
* {{Meido}}: Part of her job.
* MissingMom: Her mother died prior to the start of the series.
* NiceGirl: Unless Yumeji walks in on her at [[AccidentalPervert the wrong moment]] or a guy talks about her weight.
* PatientChildhoodLoveInterest: Clearly has very strong feelings for Yumeji, and apparently has had them for some time.
* {{Tsundere}}: A mild Type B towards Yumeji.
* [[YouGottaHaveBlueHair You Gotta Have Lilac Hair]]: In the manga.

->Voiced by: Creator/JojiNakata (JP), Creator/ChrisAyres (EN)
[[quoteright:250:https://static.tvtropes.org/pmwiki/pub/images/chaser_john_doe_19927.jpg]]

A mysterious cat-like Dream Demon that first appears to Yumeji through a recurring dream, having taken an interest in Yumeji and his ability. He is very powerful and owns an impressive army of other cats, which manifest into female kemonomimi during battles. His intentions and loyalties remain unclear, and refers to himself as an "ally of truth", but has nonetheless become something of a mentor figure to Yumeji. [[spoiler:He currently inhabits the body of a black cat in the real world.]]
----
* AloofAlly: Only helps when he deems it necessary.
* AnimalMotifs: Cats.
* AwesomeMcCoolName: Seriously, '''''Chaser John Doe!'''''
* BadassBaritone: Both Creator/JojiNakata and Creator/ChrisAyres give John a ridiculously awesome baritone.
* BadassCape: He even keeps it as a full-on cat!
* CatsAreMean: {{Subverted|Trope}}. He turns out to be an ally.
* ChainsawGood: John's weapon is a guillotine-shaped chainsaw-like sword.
* CoolMask: He replaces it after Merry breaks the first one.
* DarkIsNotEvil: He's a sinister figure at first, but it turns out he's one of the good guys.
* ExpressiveMask: His mask can subtly shift between a smile or frown.
* FunnyAnimal: He's apparently an anthropomorphic cat.
* HeroAntagonist: He debuted invading Yumeji's dreams in an effort to take over his body. He later settled for a cat.
* ImprobableWeaponUser: WordOfGod[[invoked]] says its a cross between a saw and guillotine.
* InTheHood: He never takes his hood down.
* ItAmusedMe: Acts like this at times, such as having CatGirl nurses treat Yumeji and [[AllMenArePerverts feigning surprise when he complains]].
* LargeHam
* MeaningfulName: Like all Dream Demons. He is a nightmare of pursuit ("Chaser"), of being stalked and hunted by a faceless menace ("John Doe") for an unknown reason, across a cityscape that feels familiar, but subtly shifts and changes so you never quite escape, no matter how hard, or long, you run. It's also meaningful in that he is one who hunts after the truth, as a "John Doe" is a pressing question of identity, a mystery needing an answer. He's compelled by his nature to embody his name in many possible ways.
* NobleDemon: He's surprisingly helpful when it counts.[[note]]A major example is meeting Yumeji after he [[TakingTheBullet stepped in front of Engi's sword to protect Merry]] in the previous chapter. He expressed surprise at Yumeji somehow managing to stay conscious after suffering a rather "violent injury to the soul". That, and it would be pretty easy to take him as a vessel, but he turned it down because "acting like a cat that sneaks into places is not an interest of mine." Another one is when he helps Yumeji develop his "Lucid Gadget".[[/note]]

* SeekerArchetype: Refers to himself as an "ally of truth".
* SharingABody: With a cat.
* TheSmartGuy: A key source of info to the group.
* StealthMentor: All those attacks on Yumeji were preparation for what was to come.
* SuperSpeed: He isn't called the "Chaser" just for pursuing the truth.
* UnusualEars: The things poking out of his hood.
* WhiteMaskOfDoom: Always wears one. {{Justified|Trope}}, since it plays into his MeaningfulName.

->Voiced by: Tomoko Akiya (JP), Creator/LuciChristian (EN)
[[quoteright:250:https://static.tvtropes.org/pmwiki/pub/images/yui_kounagi_21714.jpg]]

Yui is the vessel of the Dream Demon, Engi Threepiece, but unlike possessed persons that were seen thus far, her relationship with her Dream Demon is a sisterly one of mutual respect. Yumeji and Merry first meet Yui at the supermarket, and soon discover that there is more to her than meets the eye (unless it's Yumeji's eye). There are several jabs at her inability to cook, for which she has been labeled "Magical Chemical Cooking Yui" for her foods' severely distinctive and lethal tastes.
----
* BigSisterInstinct: To Engi, although which of them is literally older is unknown.
* TheChick: Because of her connection with Engi she ends up accompanying the group on most of their exploits, where she provides no combat support, but plenty of emotional support.

* LethalChef: She is called "Chemical Magical Cooking Yui" for how bad she makes food.

* NiceGirl: She's very sweet and kind-hearted.
* PinocchioNose: She has a tell when she is lying; when she lies she touches her hair with her right hand.
* RomanticTwoGirlFriendship: With Nao most strongly, though some with Engi. And taking Nao's apparent crushing on bit character Hino-senpai into account, maybe some ThreesomeSubtext for the yuri-minded.
* ShipTease: With [[LesYay Engi, Nao]] and her [[InvertedTrope Straight]] [[GayOption Option]] Yumeji.
* [[StealthPun Nightmare]] [[NightmareFetishist Fetishist]]: Implied to be into the occult.
* SharingABody: Again, with Engi.
* WillingChanneler: She and Engi have this relationship, alternating control of Yui's body.
* YouRemindMeOfX: Reminds Engi of her sister Patty.

* ItsPersonal: Her vendetta against Heracles.

* NiceJobBreakingItHero: [[spoiler:Her killing of other Dream Demons in her vengeful crusade actually help Hercules' plan to damage the Gate. He even thanks her himself.]]
* PrehensileHair: Not just shaped like wings, it can actually be used as wings!
* RevengeBeforeReason: After the battle with the Achtelnote twins, she's pretty much hell-bent on killing Heracles even if it means her vessel's life and having to fight her friends. She gets better after Yui calls her out about it.
* RapunzelHair: Her hair is very long and shaped into a pair of wings.
* SharingABody: With Yui.
* StormOfBlades: Can replicate her sword multiple times to this effect.
* SugarAndIceGirl: Displays shades of this.
* SwordBeam: One of her signature techniques.

Another member of the Writing Club, reflected in his odd habit of composing haiku at random moments, often with completely mundane subjects. As the only other male member of the club, he is shown to be good friends with Yumeji, and there seems to be a budding romance between him and Saki.

* {{Bishonen}}
* BlackEyesOfEvil: When [[spoiler:Hercules is in control. Brrr.]]

* {{Expy}}: Only other guy in a club alongside the male protagonist, a very cool head, a slight but [[PerpetualSmiler near-constant smile]], {{bishonen}} facial features... does he remind anyone else of [[LightNovel/HaruhiSuzumiya Itsuki Koizumi]]?
* ImplausibleHairColor: He's blond, and there's no indication that he's ButNotTooForeign.
* LongHairedPrettyBoy: It wouldn't be worth mentioning if it wasn't of comparable length to--perhaps even longer than--both Merry's and Saki's.
* MostWritersAreWriters: The most blatant example.
* NiceGuy: What he comes across as overall.
* PerpetualSmiler: Not as jarring as most examples.

A close friend of Yumeji and Isana and a fellow member of the Writing Club, she seems to be fascinated by Yumeji's [[MagicalEye ability to see into dreams]]. She is quite confident and outgoing most of the time but notably becomes rather timid when she's alone with Takateru, who she is hinted to like.

[[quoteright:250:https://static.tvtropes.org/pmwiki/pub/images/pharos_heracles_23142.jpg]]

The main antagonist and a very powerful Dream Demon. Very little is known about him, except that he is rallying fellow Dream Demons with the apparent intention of occupying the human world and supplanting the human population. John Doe speculates that this is probably not the full extent of his plan. [[spoiler:His human vessel is Takateru, a close friend of Yumeji's.]]
----
* AnAxeToGrind: His weapon is a massive battle ax.
* ArmCannon: He can turn his left arm into a lighthouse looking one.
* BigBad: Apparently. [[spoiler:Though not the only one.]]
* CheshireCatGrin: Seems to be perpetually present.
* [[spoiler:DiscOneFinalBoss: He takes up most of the antagonist spot for most of the manga. However, he turned out to be a pawn to GreaterScopeVillain who was just loaning Hercules his power.]]

* ImplacableMan: He can tank a lot.
* {{Jerkass}} / KickTheDog: Yeah, not like it wasn't completely obvious from the start, [[spoiler:but after he takes over Takateru completely, he rubs Yumeji's face in the fact that, by keeping his promise not to use his "dream vision" on Takateru, Yumeji essentially let Hercules completely take over his host. Then he taunts Engi about how weak her sister was, stating that his fight with her was boring to the extreme.]]
* LightIsNotGood: Frequently associated with light motifs.
* MeaningfulName: ''Pharos'' is the name of several historical lighthouses, including the great lighthouse of Alexandria. He's a dream of guidance, signaling others in their travels. But he's also a dream of flame (as lighthouses had to be lit by fire) and is a consuming destroyer who wishes to burn brighter. "Hercules" is the most obvious part of his name - he is a nearly godlike warrior, impossibly strong and dangerous to have as a foe. [[spoiler:And also, as the original Hercules served others in his trials and only became a demigod, so is this Hercules not the true greatest power and instead turned out to be the Dragon rather than the true villain.]]
* MegaManning: He can replicate powers of Dream Demons he defeated. He calls forth the item of the Dream Demon and creates a fiery copy that fights for him.
-->"Recollection of the flame: <[[{{Invocation}} insert power name]]>
* NoSell: Ignores Engi's StormOfBlades attack like it was nothing.
* TheUnfought: Due to the GeckoEnding of the anime, the protagonists never come across and fight him, despite being established as the original BigBad between the sixth and tenth episodes.
* VisionaryVillain: Although he's carefully avoided telling his underlings his true purpose, this guy has a clear idea of what he wants to achieve and how he'll go about it. Said goal is to [[spoiler:alter the conscious world so that Dream Demons can exist without host bodies.]]
* WithUsOrAgainstUs: His general approach to recruiting.

A notable recurring antagonist, and an underling of Hercules, whom he serves under with pride. While not the biggest direct threat and notably cowardly, his tricks and creations can be quite dangerous on their own. Merry has sent him back to the Dream World.
----
* CoDragons: Shares the position with Chain, though relying [[TheEvilGenius on trickery]].
** TheDragon: Is the sole subordinate to Pharos in the anime, due to Chain being AdaptedOut.
* {{Cyclops}}: He only has one eye and when in control of his host closes one eye.
* DemonicPossession / GrandTheftMe: Unlike some of the more benevolent Dream Demons, he completely took over his host's body without permission. This eventually caused him trouble, since a host personality not given freedom once in awhile is liable to surface at exactly the wrong moments.
** Which another of Heracles' associates [[CassandraTruth specifically warned him about]].
* DemotedToExtra: Like his boss in the anime, with even his sole fight scene being cut down, removing even his clown {{Mooks}} that he used in the original manga.
* DirtyCoward: Once Merry and Engi get past his tricks, he's an easy target and most likely would've kicked his ass long ago. It's only because of his human host that they lay off from destroying him. [[spoiler:Too bad for him, Merry found a way around this problem and locked the gate to their human hosts.]]
* ExoticEyeDesigns: His pupils resemble the Tick-Tack-Toe symbol (#).
* ForTheEvulz: Enjoyed screwing with his host's everyday life and generally acting like an asshole.
* GenreSavvy: Attacks Yumeji while he's developing Lucid Gadget, and [[LampshadeHanging lampshades]] it by stating that only TV characters give their opponents the chance to prepare.
* HumanShield: Used his host – more specifically, his host's hopes and dreams – as a shield; having become the embodiment of his host's dreams, killing Landsborough would leave his host an empty shell.
** Merry's power allowed her to TakeAThirdOption against him.
* MeaningfulName: Uses his power to trap people in a maze.
* MonsterClown: Both himself and his mooks.
* SquishyWizard: By his own admission. Still, claims to be tougher than ordinary humans, but Yumeji isn't an ordinary human.

She is portrayed as sadistic and wears revealing clothing, for which she is usually remembered.
----
* AdaptedOut: Whereas Pharos and Maze still appear ([[DemotedToExtra albeit in reduced roles.]])
* CoDragons: Shares the second-in-command position with Maze, [[TheBrute though relying more on brute strength.]]
* BastardGirlfriend: Sadistic streak, chain motif, {{stripperific}}.
* DemonicPossession: Unlike Maze, she seems to have it down to an art, and knows to give control back to the original owner once in a while.
* {{Dominatrix}}: She invokes this image.
* ExoticEyeDesigns: Her pupils resemble a chain link.
* ImprobableHairstyle: There are several streaks of a light color running down her dark hair. What colors they are exactly is hard to tell since she hasn't appeared in any color pages yet, but it definitely wouldn't be natural on a human. Not that there aren't [[YouGottaHaveBlueHair human characters with]] [[ImplausibleHairColor oddly colored hair]].
* KnightOfCerebus: Definitely one of the most serious threats the group has faced yet.
* MeaningfulName: ''Noir'' is heavily associated with darkness and the color black. ''Chain'', well... she does use chains as attacks.
* {{Stripperific}}: She's very scantily clad.
* VariableLengthChain: Not at all inhibited by the chains she wears, she's able to move freely and use them to her full advantage.

* PettingZooPerson: He's apparently an anthropomorphic cat.

* NobleDemon: He's surprisingly helpful when it counts.[[note]]A major example is when he meets Yumeji after he [[TakingTheBullet stepped in front of Engi's sword to protect Merry]] in the previous chapter. He expressed surprise at Yumeji somehow managing to stay conscious after suffering a rather "violent injury to the soul". That, and it would be pretty easy to take him as a vessel, but he turned it down because "acting like a cat that sneaks into places is not an interest of mine." Another one is when he helps Yumeji develop his "Lucid Gadget".[[/note]]
