Characters: Ghost Hunt

     Mai Taniyama 
Voiced by: Kaori Nazuka (Japanese), Cherami Leigh (English)

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. As the series progresses, it is revealed that Mai has ESP abilities, which include astral projection, psychic dreams and clairvoyance.

    Kazuya "Naru" Shibuya/Oliver Davis 
Voiced by: Yuuki Tai (Japanese), Todd Haberkorn (English)

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. Eventually, it is revealed that Naru is actually the famed paranormal researcher and psychic, Oliver Davis, and that he has very strong psychokinetic abilities.

     Lin Koujo 
Voiced by: Ken Narita (Japanese), J. Michael Tatum (English)

A Hong Kong-born practitioner of Onmyodo, Lin acts as part-bodyguard, part assistant to Naru before the investigation of Mai's school. A skilled spiritualist with a knowledge of Chinese and Japanese spiritualism and occultism, Lin also brings five bound spirits with him to act as his means of dealing with dangerous threats.

     Ayako Matsuzaki 
Voiced by: Masami Suzuki (Japanese), Colleen Clinkenbeard (English)

An outspoken 23-year-old self-styled shrine maiden whose powers and knowledge often come up short compared to the other practitioners 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.

     Houshou Takigawa 
Voiced by: Kenji Hamada (Japanese), Travis Willingham (English)

An apostate Buddhist monk with a family history of being monks, "Monk" acts as the bedrock of SPR's cases when the cause is finally revealed and an exorcism or purification is necessary.

  • Asian Rune Chant
  • Bad Ass: He's the most useful when things get really rough with his exorcism skills. This is most prominently visible in the second-to-last arc, where he kept the numerous spirits at bay pretty much single-handedly with his barrier (the rest of the team deal with the threat one-by-one). He displayed this power again in the fight against the Ebisu and was the first one to deliver a blow to the Villain Of T He Week.
  • Big Brother Mentor: To Mai.
  • Big Damn Hero: On the third arc, when he saves Naru and Mai from one of the spirits in the school.
    • There are also various moments in which he saves the day with his Asian Rune Chant.
  • The Big Guy
  • Bishōnen
  • The Brute: Among the team, his exorcism method is probably the most direct: blow the spirits away with spells.
  • Bunny-Ears Lawyer: He's actually a rock bassist, so yeah, he's not your traditional japanese monk, but he still gets the job done.
  • Curtains Match The Windows
  • Hidden Badass
  • In-Series Nickname: "Monk", by nearly everyone else. He also has a nickname when he's performing with his band, as revealed in the third arc. It's probably an audio pun, since his name (Houshou) only needs one syllable change to make it sound like monk (Bou-san).
  • The Lancer
  • Lead Bassist: Type D.
  • Nice Guy
  • Psychic Powers: He's a monk, after all. He mentioned that he used to be able to see spirits until an accident during an exorcism made that ability disappear.
  • Shipper on Deck: For Naru/Mai. On episode 11 of the anime, when Masako suggests that they should divide in couples to attract the spirit, he whispers to Mai that it was her chance to get a date with Naru.
  • Team Dad: Labeled as this by Mai.

     John Brown 
Voiced by: Nobuhiko Okamoto (Japanese), Jason Liebrecht (English)

An Australian Catholic exorcist, John backs up the team with his abilities learned from the Catholic Church to aid in exorcisms of human beings.

     Masako Hara 
Voiced by: Rie Kugimiya (Japanese), Jad Saxton (English)

A moderately famous TV psychic with actual psychic abilities, Masako is able to see the spirits and entities surrounding a case location, and is able to channel the dead in order to effectively communicate with them.

  • The Chick
  • Demonic Possession: 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.
  • Dreaming of Things to Come: It's implied that she has this ability.
  • Fire-Forged Friends: With Mai.
  • First Name Basis: She is upset when she realizes Naru refuses to call her (or Ayako) by their first name, but talks to Mai on First Name Basis.
  • Friendship Denial: As regards her relationship with Mai. She completely changes her mind after the seventh arc, though.
  • Hopeless Suitor: So far, it doesn't look like Naru reciprocates her feelings. Then again, it is Naru who we're talking about, he may not even have noticed she has a crush on him.
  • I See Dead People: Due to being a medium and all...
  • Kimono Is Traditional
  • Near Death Experience: 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 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 Big Bad (in a quite horrific way, might be added), but they're saved just in time by Lin.
  • Older Than She Looks
  • Psychic Powers: Seeing and sensing spirits, among other medium powers.
  • The Empath: She's the most sensitive to spiritual presence among the team, and her exorcism method works by communing with the dead and convincing them to depart. Compare this to Monk, whose method causes direct harm to evil spirits.
  • Tsurime Eyes
  • Yamato Nadeshiko
