[[quoteright:225:http://static.tvtropes.org/pmwiki/pub/images/30450_5944.jpg]]

A 16 year-old first-year high school student who becomes involved with the Shibuya Psychic Research (SPR) after she accidentally breaks an expensive video camera that was being used by the SPR in an investigation of an old building at her school. In the same incident, she is saved from a falling bookcase by Lin Koujo, who is injured instead; to repay her debt, she fills in for Lin to assist SPR's manager Kazuya Shibuya. After the conclusion of the first case, she is offered a paycheck for her work and a part-time position at the SPR. [[spoiler:As the series progresses, it is revealed that Mai has ESP abilities, which include astral projection, psychic dreams and clairvoyance.]]

** It happens again in the Bloody Labyrinth arc, [[spoiler: when she gets possessed by the spirit of one of the maids that was killed in the mansion. The spirit makes her experience her death in what's probably one of the most terrifying moments of the anime. The spirit possesses her again later but Masako notices and effortlessly exorcises the spirit out of Mai's body and lays it to rest.]]

''Maybe'') just to guarantee the life of one {{Jerkass}} teacher his justification being that, unwittingly or not, they still invoked a powerful death curse. [[spoiler: Naru instead takes a third option and diverts the death curse to six hundred hitogatas of innocent students, leaving everyone unharmed.]]

A 17-year-old paranormal researcher and the manager of the Shibuya Psychic Research center. Mai nicknames him "Naru" for his narcissistic (narushisuto) attitude; this nickname generally comes to be adopted by their colleagues. Though appearing cold and critical in front of his friends, he does care for them deeply and earns their trust and respect. [[spoiler:Eventually, it is revealed that Naru is actually the famed paranormal researcher and psychic, Oliver Davis, and that he has very strong psychokinetic abilities.]]

* AllThereInTheManual: There are several things about Naru that are either vaguely hinted at or not brought up at all in the anime but are explained fully elsewhere.

* BewareTheQuietOnes
* {{Bishonen}}

* BrutalHonesty: Oh, so much.
* [[spoiler:CastFromHitPoints: Use of his psychokinetic abilities severely taxes his body. The one time he does use it in the series, he collapses and is hospitalized afterwards.]]
* TheChessmaster: He plans out pretty much ''everything'' without telling anyone. Lin is too used to it to care at this point and the others never get what's going on until it's over.
* AChildShallLeadThem
* DemonicPossession: On the eighth arc.
* EeriePaleSkinnedBrunette
* FirstNameBasis: Towards Mai and Lin.
* GeniusBruiser

** TheFightingNarcissist
* NonActionGuy: Until [[spoiler: the end of the eighth arc, at least.]]

** And in the final volume of the manga, [[spoiler: SPR discovers that "Shibuya Kazuya" is apparently only an alias for Oliver Davis, a famous British parapsychologist.]]
* [[spoiler: PsychicPowers]]: At the end of the eighth arc, Lin reveals to Mai that [[spoiler: Naru has an outstanding amount of psychic powers, too much for his body to control, and that it was what caused him to pass out after briefly using said powers.]]
* RedOniBlueOni: The blue to Mai's red.
* TheSpock
* TheSmartGuy
* TheStoic

* TallDarkAndHandsome
* TallDarkAndSnarky
* TeenGenius
* UnspokenPlanGuarantee: He ''may'' tell Lin his plans, but that's only because he needs his [[PsychicPowers abilities]]. Except for that, he rarely reveals his plan, and Mai and the others have to figure it out on their own.

->Voiced by: Masami Suzuki (Japanese), Creator/ColleenClinkenbeard (English)

[[quoteright:225:http://static.tvtropes.org/pmwiki/pub/images/51626_8210.jpg]]

An outspoken 23-year-old self-styled shrine maiden whose powers and knowledge often come up short compared to the other practitioners [[spoiler:in the earlier arcs. This is due to her powers deriving from tree spirits and SPR's earlier cases being in urban areas. She is also a licensed doctor at hospital, a talented cook and quite wealthy.]]

* ActionGirl
* TheChewToy: She is often the object of tease (mainly from [[BrutalHonesty Naru]] and [[ShipTease Monk]]) due to her rituals not being very effective in the first few arcs.
* [[spoiler:ConditionalPowers: Her power stems from her connection to [[NatureSpirit tree spirits]] and is stronger when in rural areas. Unfortunately until the final arcs all the investigations occur in urban areas, so her powers are greatly limited until then.]]

* BunnyEarsLawyer: He's actually a rock bassist, so yeah, he's not your traditional japanese monk, but he still gets the job done.

** BadassPreacher
* {{Bishonen}}
* CelibateHero: Due to being a Catholic priest and all...
* FakeNationality: He is voiced by the very American Jason Liebrecht, whose Australian accent [[SoBadItsGood is less than stellar]].
* FunnyForeigner: Treated as funny mainy due to his accent.
* GratuitousJapanese: He has an accent, due to being foreigner, that seems particularly funny to other characters.
* HairOfGoldHeartOfGold
* ImprobableAge: To be a priest at age nineteen. It's pretty much impossible in real life, so...
* InnocentBlueEyes
* JesusTaboo: Subverted in episode 24, when John mentions Jesus during an exorcism early in the episode.
* KansaiRegionalAccent: Which he thought was [[CrowningMomentOfFunny standard Japanese]].
* NearDeathExperience: On the very first arc. The roof was falling down on the room he was practicing an exorcism, and it would've ended him had Mai not warned him and gotten him out of there just in time.

* TheChick
* DemonicPossession: On episode 11, although it's more or a comic relief situation. It is more serious on the eighth arc, when she summons the ghost of a person who was recently killed in order to find out who killed her, and of course, said ghost takes full control of Masako's body to talk to the group.
* DreamingOfThingsToCome: It's implied that she has this ability.
* FireForgedFriends: With Mai.
* FirstNameBasis: She is upset when she realizes Naru refuses to call her (or Ayako) by their first name, but talks to Mai on FirstNameBasis.
* FriendshipDenial: As regards her relationship with Mai. She completely changes her mind after the seventh arc, though.
* HopelessSuitor: So far, it doesn't look like Naru reciprocates her feelings. Then again, it is [[TheStoic Naru]] who we're talking about, he may not even have noticed she has a crush on him.
* ISeeDeadPeople: Due to being a medium and all...
* KimonoIsTraditional
* NearDeathExperience: On the third arc, a spirit pushes her down the stairs of the school while she was searching on her own. She was found by the others and taken to the hospital by John soon enough though.
** Not to mention [[spoiler: when she's abducted near the end of the seventh arc. Mai finds her and attempts to free them, but is captured too, and both are almost killed by the BigBad (in a quite [[CruelAndUnusualDeath horrific way]], might be added), but they're saved just in time by Lin.]]
