::'''Subaru Sumeragi'''
->Voiced by: Creator/KappeiYamaguchi (OAV's)

Subaru is the head of the Sumeragi Clan of onmyouji at the young age of sixteen, and is intensely dedicated to his work. Despite this heavy burden, he remains a sweet, naive boy who is devoted to helping those in need.

He is very close to his twin sister Hokuto, and often relies on her for emotional support. He is easily flustered by Seishirou's grand romantic gestures toward him, but holds a great respect for the man, and gradually grows to rely on his support as well.

Some tropes that apply to Subaru:

* [[spoiler: AngstComa - HeroicBSOD: He becomes catatonic after Seishirou attacks him.]]
* [[spoiler:AngstySurvivingTwin]]
* BewareTheNiceOnes: Shy, introverted, naive Subaru has his moments. He once nearly broke the arm of a guy who was harassing a blind man.
* BreakTheCutie: Subaru is uncannily innocent and sweet, and suffers more and more as the series progresses. And he hasn't even gotten to ''Manga/{{X1999}}'' yet...
* ChronicHeroSyndrome: Subaru has the bad tendency of focusing too much in helping people that he falls sick very often. And even so, he pushes himself to the limit in order to finish his job. And he's not nearly recovered when he has to jump into another one.
* ConspicuousGloves: Justified. The gloves are magical talismans which hide him from the man who marked him as a kid. [[spoiler: They don't work]]
* DreamWeaver: He can dive into people's dreams and/or consciences, and see/influence them to help the "dreamers" deal with their problems. He uses this power on Midori [[spoiler: and in ''Manga/{{X1999}}'', on Kamui.]]
* EntendreFailure: Unless someone makes the point straight to his face, he will be as lost as a kid.
* ForgetsToEat
* FriendToAllLivingThings: Subaru loves animals, and often bonds with Seishirou over the animals at his practice. He yearns to go to college to be a zookeeper -- however, his duties as clan head have made that dream [[TragicDream all but impossible.]] [[spoiler:This seems to be on purpose to go with his hardened demeanor after he got older and more depressed.]]
* GreenEyes (manga/artbooks) or InnocentBlueEyes (anime.)
* HalfIdenticalTwins: With Hokuto.
* LuminescentBlush: He turns red as a tomato at the drop of a hat. Particularly when Seishirou starts flirting with him.
* NiceHat: A constant feature of the outfits created for him by Hokuto.
* {{Onmyodo}}: A practitioner and child prodigy, and comes from a long line of fellow onmyouji.
* ParentalAbandonment: His only shown relative is his grandmother, who lives in Kyoto. Subaru and Hokuto live on their own in Tokyo.
* PolarOppositeTwins: Subaru is introverted, naive, powerfully magical and the head of the Sumeragi family. Meanwhile, Hokuto is extroverted, energetic, fairly GenreSavvy, mostly-a-muggle and the spare child in the family.
* ThemeNaming: Like Hokuto and Seishirou, Subaru is named after a constellation -- "subaru" is the Japanese term for the Pleiades.
** Incidental MeaningfulName: Later on in ''Manga/{{X1999}}'', [[spoiler:it is revealed Subaru is one of the Seven Seals - each Seal being born under stars in the Pleiades.]] Both he (and Hokuto, being his twin) were born under the "north star" - but the literal name went to "Hokuto," who was born first. (See her section for more.)
*** This could be taken as {{Foreshadowing}} on Creator/{{CLAMP}}'s part.
* WaifProphet: Subverted. Though Subaru looks waifish and mild, he is a combat-trained black belt. In volume six, he nearly breaks the arm of some punk who was harassing a blind man, and scares off the rest of the punk's friends with a look.
** His stature is pretty slight, but his main problem is that he often just doesn't take care of himself (such as forgetting to eat), particularly when he gets really busy (which is all the time).
* WideEyedIdealist
* {{Workaholic}}
* YaoiGuys: With Seishirou, much to his embarrassment.


::'''Hokuto Sumeragi'''
->Voiced by: Creator/MikiIto (OAV's)

Hokuto is Subaru's elder twin sister, and his loyal emotional support. She is a happy, energetic young woman, and incredibly skilled with her sewing machine. She is nowhere near as skilled as Subaru at magic, but makes up for it with perseverance (and a healthy dose of martial arts).

She wishes only the best for her younger brother, but fears that his tender heart will only bring him pain. She eagerly encourages Seishirou and Subaru's relationship, hoping to make Subaru care about his own needs and feelings. Despite this, she often senses something just a little ''off'' about Seishirou...

Some tropes that apply to Hokuto:

* AmbiguouslyBi: She and the girl she rescued in the "Smile" side-story grew awfully close, and she even refers to "going on a date with her girlfriend" in a later arc, but we find out in the [[Manga/{{X1999}} sequel]] that she fell in love with a male DreamWeaver when she used her DreamWalker powers on him by accident.
* ActionGirl: While only average in spellcasting, she is quite the BadassNormal martial artist.
* [[BigBrotherInstinct Big Sister Instinct]]: Despite Subaru being the more powerfully magical of the two. She threatens to kill Seishirou if he hurts Subaru and she's only half-joking.
* BoyishShortHair: As it helps her to sometimes play TwinSwitch with Subaru and the girl totally rock it.
* CatSmile
* DreamWalker: Revealed to have this power in X1999
* {{Expy}}: Hokuto's practically the inspiration for Manga/CardCaptorSakura's Tomoyo with her role as TheHero's closest emotional support and wardrobe expert.
* FagHag: She and Seishirou are fairly close friends, and often bake and shop together.
* TheFashionista
* GenkiGirl
* GreenEyes: Which show her cheerful persona.
* HalfIdenticalTwins: With Subaru.
* [[spoiler:HeroicSacrifice: Confronts Seishirou and demands that she be killed in Subaru's place. He obliges, and [[DiedInYourArmsTonight holds her in his arms as she dies]].]]
** [[spoiler:TakeMeInstead]]
* IWantMyBelovedToBeHappy: With Subaru, of sorts. She's his sister, not his love interest, but she's self-sacrificing to the utmost to achieve his happiness.
* PolarOppositeTwins: Hokuto is extroverted, energetic, fairly GenreSavvy, mostly-a-muggle and the spare child in the Sumeragi family. This contrasts with Subaru who is introverted, naive, powerfully magical and the head of the family.
* ShipperOnDeck: She is an insistent Seishirou/Subaru fangirl.
* [[spoiler:ThanatosGambit: As detailed later in ''Manga/{{X1999}}''. Her HeroicSacrifice was actually a gambit to both save Subaru's life and give Seishirou a LastSecondChance. It backfired horribly.]]
* SupremeChef: She says she's practising for her future {{Housewife}}'s life.
* ThemeNaming: Like Subaru and Seishirou, Hokuto is named after a constellation -- "hokuto" is the Japanese term for Polaris.
** Incidental MeaningfulName: Both she and Subaru were born under the north star, so the name could have been given to either of them - but she was born first, and therefore was "the guide." There's more to them being born under a constellation; see Subaru's section for more.
* YaoiFangirl


::'''Seishirou Sakurazuka'''
->Voiced by: Creator/TakehitoKoyasu (OAV's)

Seishirou is a friend of the Sumeragi twins; a warm, kind veterinarian in his mid-twenties. He likes to goof about with Hokuto, and constantly expresses his romantic intentions towards Subaru, to the latter's embarrassment. Despite his playful demeanor, he is a knowledgeable mentor to the twins, and often gives sobering commentary on the state of Tokyo and human nature.

Hokuto suspects him of being the Sakurazukamori, the longtime rival of the Sumeragi clan -- Seishirou always laughs the accusations off, as he, of course, has no magic ability...or does he? [[spoiler:He does, and is. His powers as an onmyouji surpass Subaru's, and he has far fewer compunctions about using them to hurt others. Over the course of the series, his true nature (and the connections he has to Subaru's foggy memories of a meeting under a cherry tree) slowly comes to light.]]

Some tropes that apply to Seishirou:

* EyeScream: Takes a knife to the eye while protecting Subaru from a woman suffering a nervous breakdown. The eye is permanently damaged.
* [[spoiler:FourEyesZeroSoul]]
* FriendToAllLivingThings: He is a kind and caring doctor to all the animals in his care, and often bonds with Subaru over their shared love of animals. [[spoiler:This and the trope itself is all a deliberate act on Seishirou's part. He uses some of the animals in his care as [[PoweredByAForsakenChild sacrificial decoys]] to deflect the negative splashback that his magic would otherwise cause on him.]]
* TheGlassesComeOff: Seishirou removes his glasses when he [[spoiler: is in "Sakurazukamori" mode.]]
* KindlyVet: [[spoiler:Or so you'd think.]]
* MilkyWhiteEyes: After his eye is injured. It's never clarified if his eye is totally missing and thus he wears a glass eye, or merely blinded to the point of being discolored. But more than likely it's merely blinded. In ''Manga/{{X1999}}'' [[spoiler: after Fuuma stabs Subaru in the same eye, after his bandage is removed, we see the same white blankness.]]
* StalkerWithACrush: He certainly is very touchy-feely with Subaru, and always knows where he happens to be, and always leaps to his protection. [[spoiler:He does literally spy on him constantly with onmyoujutsu, and grows increasingly possessive of him. Of course, he still [[BlatantLies claims he feels nothing toward him.]]]]
* ThemeNaming: Like Hokuto and Subaru, Seishirou is named after a constellation -- "seishirou" is the Japanese term for Orion.
* StoicSpectacles [[spoiler: / FourEyesZeroSoul]]. [[spoiler: Also ala Aizen, Seishirou's glasses were nothing more than a [[PurelyAestheticGlasses facade to make him look harmless.]]]]
* StraightGay: Unless he's goofing around with Hokuto, he has absolutely no CampGay mannerisms.
* WhatIsThisThingYouCallLove: [[spoiler: Seishirou, as a sociopath, literally cannot comprehend normal human emotion. The bet he made with a young Subaru long ago was to see whether he could be made to love someone, and Seishirou claims Subaru failed. [[Manga/{{X1999}} Claims.]]]]
* YaoiGuys: With Subaru.

::'''The Sakurazukamori'''
->Voiced by: [[spoiler: Creator/TakehitoKoyasu]] (OAV's)

* AffablyEvil
* BadassInANiceSuit
* BigBadassBirdOfPrey: His familiar is a large hawk.
* CradlingYourKill: He normally is showed holding his most recient victim to take them to the [[spoiler:haunted sakura tree in order to bury them. He also cradled his mother and Hokuto after killing them.]]
* DissonantSerenity
* EvilCounterpart: To Subaru [[spoiler: as Seishirou]] and to the entire Sumeragi clan.
* KickTheDog: [[spoiler: Seishirou uses his veterinary practice for magical purposes - the backlash of his spells strike the animals instead of himself, often killing them.]]
** Also, just as Subaru [[spoiler: realizes his love for Seishirou]], the latter beats him to a pulp. He simultaneously explains, while breaking Subaru's arm and kicking him around the room, that despite [[spoiler: his previous assurances of love]] he really feels nothing for anyone.
* KillTheOnesYouLove. Inverted. Sakurazukamori are killed by the ones they love the most. It's how the job is passed down. In [[spoiler: Seishirou's case he killed his [[SelfMadeOrphan mother]]]]
* ManipulativeBastard
* {{Onmyodo}}: As expected of the Sakurazukamori, and is more powerful even than Subaru and his grandmother.
* SecretIdentity: [[spoiler: Seishirou as the Sakurazukamori, though it was fairly obvious from the beginning.]]
* [[spoiler: TheSociopath]]
* WalkingSpoiler: Played with. [[spoiler:Seishirou's]] identity was practically an OpenSecret and it's crossed over into ItWasHisSled territory especially due to the sequel in ''Manga/{{X1999}}''.
