[[WMG: Reiko Mikami]]
->Voiced by: Creator/HiromiTsuru

* TheAce
* ActionGirl
* BadBoss
* BerserkButton: Losing money, cockroaches (tries to ''nuke'' her own office when she sees one) [[spoiler: and Yokoshima's death(s).]]
* CombatPragmatist: Saijou's a rank amateur compared to her.
* CoolCar: Drives a red AC Cobra in a few episodes.
* EvenTheGirlsWantHer
* FieryRedhead
* HotBlooded
* JerkWithAHeartOfGold: Very greedy and self centered and is certain to overprice her services a ''lot'' while paying her employees peanuts. That said, she does care for her companions' life and goes berserk or nearly has a HeroicBSOD when [[spoiler: Yokoshima is killed]] and genuinely cares for Kinu's well-being. There was also one instance where she chose to ''not'' do her job and get the money.
* {{Greed}}: She could easily take that spot in the pantheon of this site.
* MeaningfulName: Shiina came up with her name as an oblique reference not just to the goddess Aphrodite, but also the financial headaches Japan was going through when the manga was first published. Guess which character obviously avoided getting hit with problems...
* MsFanservice
* OneeSama: Meiko sees her as this. [[LesYay Or more]].
* RapunzelHair
* ScrewTheRulesIHaveMoney
* {{Stripperiffic}}
* TimeTravel: Her family from her mother's side has this as an ability that's triggered by lightning.
* [[spoiler: TomatoSurprise ((It turns out that her existence began in the Heian era as the artificial demon Mephistopheles. It helps explain why she's ChaoticNeutral, for starters...)]]
* {{Tsundere}}: Type A. She lets down her guard against Saijo, Kinu and her family. She is also arguably a type B since she's her harshest around Yokoshima [[spoiler: who's her love in her former life and also supposedly her future husband]]

[[WMG: Tadao Yokoshima]]
->Voiced by: Creator/RyoHorikawa

* ChivalrousPervert: He'll do whatever it takes to help the girls who care for him. Not too many of them around, unfortunately, thanks to the 'pervert' part.
* CombatPragmatist: Not to Mikami's level, but he can be surprisingly resourceful.
* CrouchingMoronHiddenBadass: Acts like a perverted idiot most of the time, but plenty of people have noted how tenacious he is at getting a glimpse of some booty (though he fails most of the time) and people like Shouryuuki and Mikami's mother have noted his incredible [[MagikarpPower growth potential]] which, according to the latter, surpasses even Mikami and Saijo. Heck, he managed to almost ''beat'' Mikami during his special training (he had aready beaten twice the number of monsters Mikami did on that same training her first time around), only losing due to hesitation. Heck, even in the first chapter clearly stated that has enormous spiritual powers.
* {{Determinator}}: As long as it involves girls. Otherwise...
* DirtyCoward: ...he turns into this.
* HiddenDepths: His old friend noted that those who actually took the time to know him will appreciate his good qualities. He ''did'' attract at least 3-4 ladies that we can see, after all, [[spoiler: some of whom were supposed to be his enemy.]]
* IdiotHero: Between TNA and his life, its always TNA.
* GenerationXerox: He may not look like his parents too much, but his developing relationship with Mikami bore such a startling similarity to his parents' that Mikami became worried on an unconscious level...
* TheChewToy: Barely a file goes by without him falling prey to AmusingInjuries or some other aggravation, whether because of Mikami's neglect, his own overactive libido, or whatever else the cosmos thinks it'd be fun to visit on him. Even ''after'' he saves the day.
** IronButtmonkey: The only thing that seems to work on him is cutting and stabbing attacks...
* WeirdnessMagnet: Lampshaded by Mikami how he attracts all kinds of female supernatural beings. [[spoiler: Ironically enough, this includes her past self...]]
* FutureMeScaresMe: Was incredulous at how competent his [[FutureBadass future self was]].
* LovableSexManiac: Like you wouldn't believe.
* MeaningfulName: Although Ironic Name would work better--Tadao means "loyal husband". Considering how he'll try to convince just about every other attractive female around his age to help him lose his virginity...
** [[spoiler: One file reveals that, yes, he got married to her 10 years later]].
* TookALevelInBadass: Eventually learns to fight on his own with his spiritual lightsaber and small spiritual balls that can create any effect as long as they're one kanji long. [[spoiler: His future self can ''travel through time on his own power'', which not even Mikami and her mother, whose super-special ability is to ''travel through time'', can do.]]

[[WMG: Okinu/[[spoiler: Kinu Himuro]]]]
->Voiced by: Creator/MarikoKouda

* [[spoiler: AstralProjection: After she is revived, she gains this ability. Unlike most examples, she can still move objects.]]
* [[spoiler: BackFromTheDead: After Shizumo-hime is slain.]]
* CuteGhostGirl: [[spoiler: At least until after Shizumo-hime is slain. Then you can drop the "ghost" part.]]
* {{Miko}}
* RapunzelHair
* PutOnABus: For a while.
* {{Tsundere}}: Type B. Only Yokoshima can bring that out in her.

[[WMG: Emi Ogasawara]]
->Voiced by: MichieTomizawa

* ActionGirl
* AmbiguouslyBrown
* BikerBabe: Emi's frequently seen with her motorcycle, and seems to be the only one in the cast who owns one.
* ClingyJealousGirl: Poor Pietro...
* DealWithTheDevil: When she first began (unofficial) ghost sweeping at the age of 15, she did so with the aid of a bound demon named Belial. Shiina [[WhatHappenedToTheMouse never explains in the sidestory]] what happened to Belial between then and the main series, when we see him locked up.
* HiddenDepths: Her backstory is surprisingly serious and tragic.
* [[HitmanWithAHeart Hitwoman with a Heart]]: Eventually leading her to quit, apparently.
* ParentalAbandonment: They died when she was ten.
* TheRival: To Mikami.

[[WMG: Yakuchin]]
->Voiced by: Creator/TakeshiAono

* DirtyOldMan: Gets along well with Yokoshima...as long as he's not using him as a lab-rat...
* HonestJohnsDealership: Rule #1 when shopping: ''Do not let him foist untested prototypes on you''.

[[WMG: Dr. Chaos]]
->Voiced by: Creator/ShigeruChiba

* DefeatMeansFriendship: He was presented as an enemy to Mikami at first, but two defeats and one case where they need to work together makes him a more neutral character.
* [[spoiler: MayflyDecemberRomance: He abjured a relationship with Princess Maria precisely because he knew he'd outlive her, and she deserved a more mortal mate. Nonetheless, he made sure her image lived on as the mystic robot Maria.]]
* MadScientist: Hooo boy...
* MySkullRunnethOver: Because his brain has become completely full with information, learning something new means that one of the earliest things still remembered gets overwritten. It really says something that he can understand how the Tenshi Luopan works at first sight, but at the same time forgets what 2+2 results in...
** Also, he can't remember how to build Maria.
** [[spoiler: If the dream at the end of the series is true he eventually he does manage to mass produce androids. But in a somewhat bitter-sweet turn he has also forgotten about his past adventures with Mikami and company.]]
* OlderThanTheyLook: One arc shows him as a strapping 'young' man...who's at least 200 years old.
* IUsedToBeALooker: Not too bad on the eyes when he was younger.
* PerpetualPoverty: He's practically the poster child.
* Really700YearsOld: He's been around since before the dark ages, apparently.

[[WMG: Maria]]
->Voiced by: Creator/WakanaYamazaki

* ActionGirl: Well, Action Robot Girl...
* RidiculouslyHumanRobots: Although it makes sense here, since she was designed in part as a memorial to an old acquaintance of Dr. Chaos's. Played with when a love potion makes her fall in love with Yokoshima and tries to kiss him... with a metal head and enough force to destroy concrete walls...

[[WMG: Meiko Rokudou]]
->Voiced by: Creator/KumikoNishihara

* TheBeastmaster: She has a retinue of twelve shikigami under her control, but no thanks to her complete lack of self-confidence, it's ''very'' easy for her to lose control over them. When that happens, Anything standing around her turn into ruins.
* BerserkerTears: She cries and her Shikigami goes ballistic...which happens ''a lot''.
* CloudCuckooLander: She could function somewhat normally in society, but when Nightmare invades her mind, he has no idea what goes on in her head...so much so he had to abandon his attempt.
* EasternZodiac
* TheOjou: Her family is ''incredibly'' rich.
* OlderThanTheyLook: Meiko's mother was pregnant with her before Mikami's parents even met. Yet you could be forgiven for thinking she's a little younger than Mikami.
* PersonOfMassDestruction
* ShrinkingViolet: Self-confidence is a ''severe'' rarity in her bloodline.

[[WMG: Father Kazuhiro Karasu]]
->Voiced by: Creator/KazuyukiSogabe

* BadassPreacher: In his youth. Also note that this is Mikami's teacher.
* CovertPervert: ''Possibly'' in the film, when he sees Emi fawning over Peter, he [[NotSoStoic cries a bit]] out of jealousy, lamenting his oaths.
* Proto-{{Otaku}}: In the ''GS Mikami '78'' arc, he is seen playing the original SpaceInvaders and takes offense at Mikami's mother branding fans of SpaceBattleShipYamato and StarWars, as well as cosplayers, as weirdos.
* SmokingIsCool: In 1978, that is. Suffering more than usual trying to climb the Sunshine building got him to swear off of it, though.
* StupidGood: According to Mikami.

[[WMG: Pete/Pietro de Bloodeau]]
->Voiced by: Creator/ToshiyukiMorikawa

* {{Bishonen}}: Officially the best-looking guy in Yokoshima's TrueCompanions.
* CallingTheOldManOut
* HotBlood
* IHateYouVampireDad: No, not for the vampirism. The whole island country Pete belongs to is populated entirely by vampirs. Pete's more upset about his father's [[TakeOverTheWorld megalomania]] and [[StupidEvil insanity, stupidity, and senility]] than anything else.
* ShoutOut: [[StreetFighter "Vampire Sho Ryuu Ken"]], anyone?
* StupidGood: Veers into this territory sometimes thanks to his HotBlood.

[[WMG: Piper]]

* FountainOfYouth: That needle of his lets him turn people into little children...whose fear he can then incite...
* MonsterClown
* [[spoiler: RodentsOfUnusualSize (The true form of Piper)]]
* WeaksauceWeakness: His little helpers are very susceptible to baby jokes. He himself fears cats.

[[WMG: Nightmare]]

[[WMG: Shouryuuki]]
->Voiced by: Creator/WakanaYamazaki
* ActionGirl
* CuteMonsterGirl
* OurDragonsAreDifferent

[[WMG: Medusa]]
* ChristmasCake: Well, she's Really700YearsOld. It's her interactions with Mikami and Yokoshima (the former called her granny) that creates this situation.
* EvilCounterpart: To Shouryuuki
* LadyOfWar
* [[spoiler: {{Reincarnation}}: During the battle on the moon, she had to do this after getting shot by Mikami. She did it by performing mouth-to-mouth on Yokoshima and nearly going out ChestBurster style into a younger, "fresher" version of herself.]]

[[WMG: Aiko]]
* AnimateInanimateObject
* FantasticRacism
* ClingyMacGuffin: She's stuck to her desk.
* OrdinaryHighschoolStudent: [[IJustWantToBeNormal She wants to be one]], except, you know...see above.

[[WMG: Michie Mikami]]
* ActionMom
* BadAss: She's stronger than Mikami in most of her appearances.
* CombatPragmatist: Even more than Reiko.
* KnightTemplar: Has no qualms implementing some pretty extreme strategies.
* TimeTravel

[[WMG: Tiger Torakichi]]
* DoesNotLikeWomen: He doesn't really hate them, he's just really shy and afraid of losing control of his libido when around them.
* TheBigGuy: Among Yokoshima's TrueCompanions and just big, period.
* LargeHam
* MasterOfIllusion
* OcularGushers: Does this a lot in his first appearance.

[[WMG: Date Yukinojou]]

* BloodKnight: His primary motivation for joining Medusa was to fight strong enemies.
* BattleCouple: Him and Yumi.
* DangerousForbiddenTechnique: Unlike Innen and Kankuro, Yukinojou is ''very'' careful with the Masoujutsu from the beginning. Under ''no'' circumstances will he let it persist to the point that he risks getting corrupted into a demon. Later on, he decides that he needs more power than that, so decides to find an alternative form of spiritual armor that ''doesn't'' have the corruption risk--in other words, not derived from demonic energy.
* HeelFaceTurn: He gets so thoroughly disgusted with the lengths Medusa will go to achieve her goals that he renounces her, and ultimately even upgrades his infernal-energy armor into a less dangerous version with Hanuman's help.
* MommasBoy: Yukinojou flat-out ''idolizes'' his mother and her zealous care for him, to the point that Kankuro, Yokoshima and Mikami think it [[OedipusComplex crosses into incestuous]]. Later on, it turns out his mother died when he was young, [[DeceasedParentsAreTheBest giving the reader something to potentially temper]] that problematic image with.
* TheRival: Considers Yokoshima as this. [[spoiler: Turns out he ''was'' Yokoshima's rival Tamiya racer when they were kids.]]

[[WMG: Kankuro Kamada]]

* DangerousForbiddenTechnique: Unlike Yukinojou, he gets completely corrupted. Thing is, it's pretty clear that that's what he ''wanted''.
* DepravedHomosexual: ''Really'' into Yukinojo, to the latter's horror.

[[WMG: Inukai/[[spoiler: Fenrir]]]]
* BadAss: The entire GS troop couldn't take him down the first time they fought him.
* EverythingsBetterWithSamurai
* {{Lolicon}}: Is mistaken for this by Yokoshima.

[[WMG: Shiro Inuzuka]]

* PettingZooPeople: An inukami, in this case meaning that Shiro has a dog's fangs and tail while in humanoid form.
* PlotRelevantAgeUp: Adsorbing some of Yokoshima and Mikami's energy to heal actually accelerates Shiro's maturation by a few years, [[spoiler: in the process revealing that "he" is actually a "she".]]
* [[spoiler: SamusIsAGirl]]
* YouKilledMyFather: Shiro's motive for chasing down Inukai.

[[WMG: Teruhiko Saijou]]

* {{Biseinen}}: Apparently was a {{Bishonen}} and, as implied by Marin, ReallyGetsAround...
* TheAce: Was introduced as this and, as the series goes on, was shown to be a capable leader.
* CombatPragmatist: Odd when you consider his proclaimed devotion to justice, until you realize that he's more worried about just results than just means.
* TheRival: With Yokoshima for Mikami's affection. [[spoiler: It's a holdover from their previous reincarnation.]]

[[WMG: Hanato Kobato]]

* NamesTheSame: She has the exact same name as the eponymus title character of one of Creator/{{CLAMP}}'s [[{{Kobato}} recent works]]?
* PerpetualPoverty: Her family was cursed with constant poverty through a binboukami. It didn't exactly help that, until they met Yokoshima, the binboukami's attempts to turn himself into a kami of fortune never got anywhere.

[[WMG: Valkyrie]]

* DrillSergeantNasty

[[WMG: Siegfried]]

* DrillSergeantNasty: When he has his hat on.
* SplitPersonality: Becomes a NiceGuy when his hat comes off.

[[WMG: Shizumo-hime]]

[[WMG: Hyakume]]

* CuteMonsterGirl
* EyesDoNotBelongThere: See all those eyeball accessory looking things all around her body, on her arms, dangling from her ears? They're all ''real eyes''. But she's cute, so we're not complaining.
* MeaningfulName: Her name literally means "100 eyes", and she's basically a scout unit who can see great distances.

[[WMG: Ashtaroth]]

* AGodAmI: He certainly acts like this towards his minions, and becoming the sole god of the universe is his ultimate goal. [[spoiler: Well, [[DeathSeeker one of the two goals]] he's willing to accept, at least...]]
* BadBoss: Poor Dogura, even if it is a restorable automaton...
* BigBad: Though the series doesn't actually have one, he's probably the next best thing since a ''lot'' of the series' important events revolve around his actions.
* [[spoiler: DeathSeeker: Ashtaroth couldn't handle the fact that his role as a demon, to maintain the flow of chaos and generally keep the universe from stagnating, meant that he'd be vilified more often than not. As far as he was concerned, there were only two acceptable alternatives--[[InTheirOwnImage rewrite the whole of reality to his whims,]] and this.]]
* EmptyQuiver
* [[spoiler: PutThemAllOutOfMyMisery: Basically, the combination of his two goals means that either he goes, or the universe that causes him so much pain goes.]]

[[WMG: Dogura Mogura]]

* Golem

[[WMG: Hanuman]]

* Expy: Despite his name, he more closely resembles [[JourneyToTheWest Songoku/Sun Wu Kong]].
* StealthMentor: His method of training involves [[IKnowMortalKombat playing fighting video games with his students for months on end...]]

[[WMG: Mari Ichimonji]]

* {{Delinquent}}
* GoodOldFisticuffs: Her spiritual ability is to punch out supernatural beings.
* TomboyAndGirlyGirl: Comparatively speaking, her and Yumi, once Okinu reconciles them.

[[WMG: Kaori Yumi]]

* AlphaBitch: Until Okinu gets her to see things from Ichimonji's perspective, that is.
* BattleCouple: Her and Yukinojou.
* BlackEyesOfEvil: ''Sparkling'' Black Eyes, at that. Not really evil though. It's actually a dig at the BishojoGenre of the era, which features such eyes prominently.
* Ojou: Her family's pretty rich and quite well known in GS circles.
* TomboyAndGirlyGirl: Ichimonji and her...Well, Yumi could be girly if you squint.
* TrainingFromHell: She can't stand the idea that the super-rigorous training Touryu exorcists go through is [[HardWorkHardlyWorks not the minimum of rigor required]] to be a good GS, sparking her acting like the AlphaBitch at first, especially when Ichimonji gets Mikami's respect.

[[WMG: Marin Megumi]]

* HotWitch
* ThroughHisStomach: Her exorcism methods include cleaning and cooking up super-delicious and nutritios food.

[[WMG: Papilio]]

* AndCallHimGeorge: Although the threat to Yokoshima and Hyakume doesn't come directly from Papilio, but rather her ''other'' pets, who include the likes of ''Kerberos''. Yes, she expects them to get along just fine.
* AnimalMotifs: She was made from a butterfly, as her name indicates.
* BrattyHalfPint
* HeelFaceTurn
* TokenMiniMoe

[[WMG: Luciola]]

* ACupAngst: Brought up a few times.
* [[spoiler: GoOutWithASmile]]
* HeelFaceTurn
* Hologram: Her basic fight tactic involves illusions of herself.
* [[spoiler: TheGwenStacy: For Yokoshima. It's implied she will be reincarnated as his daughter.]]
* [[spoiler: ReplacementLoveInterest: [[InvertedTrope Inverted]]. She fears she is one for Yokoshima, but doesn't seem to mind in the end.]]
* WrenchWench

[[WMG: Vespa]]

* [[spoiler: HeelFaceTurn: Shortly before Astaroth's giant form awakens.]]

[[WMG: Tamamo]]

* BrattyHalfPint
* PettingZooPeople: Her tails from her kyuube no kitsune form manifest as her hairstyle in her human form.
* TrademarkFavoriteFood: Fried tofu, traditionally something that kyuube no kitsune are addicted to in Japanese lore.
* Tsundere
