The Agency Kensuke Nimura (弐村 剣輔, Nimura Kensuke) Voiced by: Minoru Shiraishi
The protagonist, an ordinary high school student who has had the ability to see ghosts ever since he was a kid. Because of this, he always felt different, but things changed after meeting Kagura. He started practicing
kendo from a young age, being the son of a kendo instructor, and utilizes his skills during missions. When fighting, he sometimes dons a pair of sunglasses. The story-line concerns his growth as a spirit-user, his main weapon being swords. He initially wields "Michael #12," but after breaking it in a battle, is given the sword "Michael Revolution" in its place. He supports Kagura during her emotional lows, and a bond develops between them.
Kensuke has the same sesshōseki that transformed Yomi into an evil spirit, embedded near his heart. According to Yomi, the sesshōseki itself wished to be placed there. The stone gifts him with memories, as well as allowing his sword techniques to become radically more powerful. This stone was later removed when Imawano Setsuna forcefully tore it from his body in the Garden of Tamamo, fatally damaging his body in the process. He survived after Kagura defeated Setsuna and revived the Kyuubi, using its powers to restore his body from the brink of death. After firming his resolve to save Kagura from being controlled by the Kyuubi, he unleashes the true power of the Michael Revolution, the ability to cut through dimensions.
After the Counter-Measure department was broken up he stayed with Kagura as a Psychic consultant. He faces off against Kirin only to have his eye slashed protecting Izumi.
Kagura mentions that Kensuke has a unique presence which puts spirits at ease and even Byakuei feels more secure when Kensuke is near.
Kagura Tsuchimiya (土宮 神楽, Tsuchimiya Kagura) Voiced by: Minori Chihara
Always smiling, Kagura is the heroine of the story. She is feisty and ambitious and can put up a good fight with her spiritual beast, the Ga-Rei Byakuei (nicknamed Shirō), an
inugami who resembles a large white dragon. She controls Byakuei from the seal on her back and a long chain that connects her soul to his, so any damage Byakuei receives also damages her as well. Over time, she becomes stronger and more motivated because of the support that Kensuke gives her. She shows signs of having feelings for Kensuke, as she gets jealous when Shizuru and Kensuke are spotted alone together and is shocked when Kyouko tells her that she should go out with Kensuke if she's worried about him. Although she initially treats Shizuru as a rival, they become closer as events in the manga progress.
The anime shows a younger Kagura. Originally a shy, dutiful and sad young girl, her meeting with Yomi after her mother's death changed her life. She came to love Yomi, who treated her like a sister, and was under great emotional stress when she found out that Yomi had turned against the Agency and all of humanity.
In the anime, Kagura receives Byakuei from her father prior to his death, and her new weapon from Michael Kohara, the "Michael 13." The "Michael 13" would later be destroyed in a battle with Yomi, which is why Kensuke received the "Michael 12" instead of the 13. In the same battle that broke the "Michael 13," Kagura killed Yomi with the weapon Noriyuki left before his departure. Her bitter victory was a key which unlocked her restraints against fighting former-humans, as, according to Iwahata, once she killed the most important person to her, she would no longer have any reservations about killing anything else.
After gaining all of the sesshōseki and being deemed the victor, Kagura becomes the Kyuubi itself rampages across the city, eventually being stopped by Kensuke. She has lost her memories as a result. She attends Kensuke's school and makes a temporary Psychic Consultant group. She's decided to continue the spirit investigations feeling it may unlock something.
Noriyuki Izuna (飯綱 紀之,
Izuna Noriyuki)
Voiced by: Shinya Takahashi
An old friend of Kagura and ex-fiancée of Isayama Yomi. He uses Kudagitsune, or spirit pipe foxes, to spy on people and fight. He's very perverted, and constantly tries to grope Kagura, with painful results. He is part of the information department.
Underneath his perverted and cheerfully helpless facade, Izuna is very powerful, able to fight on equal terms with Yomi. He is very knowledgeable on the subject of spirits and is skilled in hojutsu. He treats Kagura like a little sister and demonstrates concern for Kensuke. As Yomi's ex-fiance, he still had feelings for her. Behind all of his jokes and lecherous acts lies a man full of pity and self-loathing.
Izuna sees a lot of himself in Kensuke, which is why he wants to help Kensuke become stronger so that Kagura won't share the same fate as Yomi.
Ga-Rei: Zero reveals how different Noriyuki was before the events of the manga. He was more of a playboy rather than a pervert, which angers his fiancée, Yomi, even though he does care about her.
Ga-Rei: Tsuina no shou reveals he saved Tsuina from a evil spirit and fought Mikado when he was planning to kill her to stop a spirit, claiming "Pretty girls are the countires treasure" and took her under his wing for training. He claims to be interested in her but given his nature he could be joking.
Kyouko Mine (峰 京子, Mine Kyōko)
An agent of the Ministry, and heir of her clan. She controls paper spirits, or shikigami. She gets along well with Kagura, and often tries to get her and Kensuke together. She is very proud, and went to fight Kidoumaru when he broke through her shikigami barriers. She ended up badly injured, but landed a critical blow on him. Usually, she is amiable and friendly. She's currently back in her parent's home in kyoto
Fujiko Mine (峰 不死子, Mine Fujiko)
Head of the Ministry as well as Kyouko Mine's grandmother. She may be old but she's not a person to mess with. In the events of
Ga-Rei: Zero, she retired from her position and gave it to her other granddaughter, Ayame Jinguuji. After Yomi's attack on Ayame and Kiri, she left retirement to resume her former duties in Ayame's place. After the agency was disbanded she watches over kagura.
A side-chapter featuring a 18 years-old Fujiko reveals that she took care of Kagura's grandmother, Ruri, before the formation of the Agency after WWII.
Kouji Iwahata (岩端 晃司, Iwahata Kōji) Voiced by: Tetsu Inada
An agent of the Ministry who dislikes Izuna. He is very tall and muscular, and a powerful spirit-user. He uses guns to fight. Some of the more comical moments in the manga suggest that he may be homosexual (which is confirmed in the anime). He is an ex-soldier, and was hired by a mercenary corporation until the Agency recruited him for his ability to sense spirits. After the department breaks up he disappears until chapter 38. In anime, he was attracted to both Kensuke and Kazuki, which made them both uncomfortable.
Ayame Jinguuji (神宮寺 菖蒲, Jingūji Ayame) Voiced by: Mai Aizawa
The Minister of Environment during the events of
Ga-Rei: Zero and Fujiko Mine's other granddaughter. Despite being confined to a wheelchair, she is nice and kind-hearted person with a relaxed air. While likable, she is very serious and earns her respect from her subordinates. Her personal assistant is Kiri Nikaidou who she affectionately calls "Kiri-chan."
She confronts Yomi and is later presumed to be dead, thus explaining why her grandmother, Mine Fujiko, returns to take her place as the head of the Ministry. In the last episode, she is seen alive and well in a hospital talking with Kiri.
It is hinted in episode 11 that Ayame may be married (thus suggesting that Jinguji may actually be her husband's family name). She is shown taking out a ring and a photograph of her before she became crippled, holding onto a man whose face is not shown. During her confrontation with Yomi, Ayame states that she once killed someone more important to her, hinting that her husband may have suffered corruption himself and was killed by her.
Ayame is also the only person who addresses the spiritual beasts (chiefly Ranguren) with nicknames that end in "-chan" (eg. Ranguren as Ran-chan).
Kiri Nikaidou (二階堂 桐, Nikaidō Kiri) Voiced by: Maki Tsuchiya
Ayame's personal assistant who helps her in her duties as minister. She has a serious work attitude and is very loyal to her boss, Ayame, and doesn't hesitate to scold others who disrespect her boss. She serves as the disciplinarian and the harsh voice of the Agency, in contrast to Ayame's friendly attitude. She is last seen in hospital talking with Ayame about Yomi's attack on HQ two years ago. She appears to have suffered mental damage due to her ordeal with Yomi, becoming childlike and addressing Ayame as "onee-chan" (elder sister).
Kazuki Sakuraba (桜庭 一騎, Sakuraba Kazuki) Voiced by: Minoru Shiraishi
An agent of the Ministry. He is a young and sarcastic, annoying yet talented man around the same age as Noriyuki during the events of
Ga-Rei: Zero. Interestingly, his weapons are two suitcases that open up at the bottom to reveal rows of muzzles, a kind of multi-row gatling, which he also uses as melee weapons. Later in the anime, it is revealed that Isayama Yomi killed him because of Noriyuki's inability to kill her, explaining why he does not appear in the manga.
Nabū Brothers (ナブー兄弟) Voiced by: Norio Wakamoto
Two large twin brothers who both have the same name, as they come from a culture that give twins the same name. Both brothers tend to finish each other's sentences. Because they look identical, it leads some of their teammates to confusion. In the manga, only one of the Nabuu brothers appears (as a minor character with no lines) since the other brother was killed by Ranguren in
Ga-Rei: Zero. The surviving Nabuu was later killed during the Jugondō's attack on the Agency, after trying to protect Fujiko Mine from enemy fire.
An
omake in volume 5 of the manga states that the Nabuus are part of the
San people from Africa, further confirmed in their character page on the anime's official website. According to the omake, they lost their home and family to war.
Michael Kohara Voiced by: Hirokazu Hiramatsu
A large man from Australia who speaks bad Japanese with a foreign accent, frequently mixing in some English words. He is Iwahata's master and the creator of most of the Ministry of Environment's weapons from the practical guns and swords, to the often bizarre irons and boilers. Because of his appearance, he tends to be arrested by the police for indecent exposure. Despite being outlandish, he is greatly respected in the Agency for his skill, his creations famed for their ability to augment the user's spiritual output by several times. He possesses mid-tier spiritual abilities.

Jugondō Shizuru Imawano (忌野 静流, Imawano Shizuru)
A mysterious girl who first encounters Kensuke at school, and then corners him in the bathroom. She demonstrates knowledge of the sesshōseki and threatens him with a gun, but then flirts with him. She reveals she has a sesshōseki of her own on a necklace. She is a lively and flirtatious girl but is emotionally closed-off, and gets angry with herself when she gets closer to Kagura and Kensuke, as she is afraid of becoming too involved. She has been forced to kill from a young age, and feels that there is no way out of the path set for her as heir to a criminal organization, something Kagura sympathizes with. There is a competition between her and Kagura to obtain the most sesshōseki, with Kensuke as the prize. She is currently traveling with Izuna to find her sister.
Setsuna Imawano (忌野 刹那, Imawano Setsuna)
Shizuru's sister, who used to be very close with her. She was a genius of the Jugondō, which made the head of the Jugondō, her father, feel threatened. He tried to have her assassinated and used Shizuru as a hostage, and so she disappeared, leaving Shizuru distraught but safe. She turns up when her father comes to Tokyo, and kills him immediately with the other members in a coup, leaving her in control of the Jugondō. She later attacks the Agency and kills most of the agents, except for Kagura, Kensuke, Kyouko and Iwahata.
Setsuna is a skilled fighter, able to easily toy with Kensuke. She has the "Eye of Satori," a telepathic ability that enables her to read minds. As a consequence, one of her eyes is remarkably different from the other. She has a spirit beast, a water-using ogre-like creature called Suiko (Water Tiger). She is ruthless and ambitious, willing to kill her own sister and subordinates. Her goal was to set the world into eternal war.
During the fight in Tamamo's garden she killed Kensuke. After the kyuubi was revived she lost an arm to protect Shizuru. She has disappeared from the hospital.
Antagonists Kidōmaru (鬼童丸)
A spirit who helps Yomi. He is a swordsman in samurai attire, and is very powerful. He is critically injured by Kyouko, but not before he almost kills her. Later, he is finished off by Kagura.
Yomi Isayama (諫山 黄泉, Isayama Yomi) Voiced by: Kaoru Mizuhara
Sister-figure of Kagura Tsuchimiya who turned evil because of the power of the sesshōseki. Also, she was the person who killed Kagura Tsuchimiya's father. She was killed by Kagura herself and has turned completely evil in her afterlife. She was extraordinarily talented when alive and slaughtered over 70 ministry agents by herself, and defeated the head of the Tsuchimiya clan and his spirit beast, Byakuei. As an evil spirit, she becomes even more powerful. She tries to awaken a great demon sealed in Tokyo, and seals a piece of the sesshōseki in Nimura Kensuke. For this, she incurs Kazuhiro's wrath, and he takes away her own sesshōseki. She dies when the demon is re-sealed.
Yomi's past is prominently revealed in
Ga-Rei: Zero, where she is shown to be more of a tragic heroine. She lost her parents at a young age to specters, and was taken in by Isayama Naraku, then head of the Isayama family. Yomi grew to love and respect her foster-father, and polished her skills to repay him for his kindness. Her efforts led to her inheritance of the priced Isayama heirloom, the sword Shishio, which held the spiritual beast Nue in it. Before Naraku's death, she was betrothed to Izuna Noriyuki and would have succeeded Naraku as the next Isayama head. However, Naraku's death at the hands of her cousin Mei, who was jealous of her good fortune, and the alteration of Naraku's will, resulted in her being stripped of her position in the family and therefore her entire inheritance. Yomi eventually found out the truth behind her father's death, revealed by Mei herself after the latter lured her out in order to kill her. Partly in self-defense, she killed Mei and avenged Naraku, but was ambushed by Mitagawa Kazuhiro, who wounded her so badly that she became hospitalized, her throat and most of the tendons in her body cut and unrepairable, unable to talk or move. This, in addition to the suspicion that she had murdered Mei, led to a series of events that caused her to succumb to Mitagawa's temptation to accept the sesshōseki. Though Yomi managed to retain some control over her mind, she had nonetheless fallen under the destructive influence of the stone, causing her to kill many many members of the Agency. Ultimately, it was her love and desire to protect Kagura that caused her death at Kagura's hands, in a desperate wish that she could remove anything that would harm Kagura, including herself.
As of Chapter 34 a girl who looks like Yomi named Izumi Isoyama has transferred to the school as a result of the Kyuubi disaster and befriended Kagura. She admires Kagura in the same manner Kagura admired Yomi. When kagura was in danger she instinctively used Kensuke's sword to split the spirit in half. At the end of 35 she said "Kagura, I won't let anyone else have you".
Kazuhiro Mitogawa (三途河 カズヒロ, Mitogawa Kazuhiro) Voiced by: Megumi Matsumoto
A boy who used to belong to the Agency. He was enthralled by the sesshōseki, hoping to use the Kyuubi's powers to revive his mother, an exorcist who had been previously killed in action. When Lady Tamamo appeared to him in the Vatican's library, he willingly became one of her minions, sparking off the events in
Ga-Rei: Zero and the first 7 volumes of the manga. He was the one who gave Yomi her sesshōseki, and later took it away after he was displeased with Yomi giving one to Kensuke. He mentions a "Lord Tamamo" as his overlord, the former mistress of the Kyuubi before its sealing. After Yomi's demise, he is next seen participating in the Jugondō coup as Setsuna's underling. He removes Kagura and Kensuke's souls from their bodies, and takes them to a spirit dimension he calls "Tamamo Garden", where they encounter Lady Tamamo.
He uses insect-related magic, and seems to have powers related to the sesshōseki, such as being able to remove the souls of people who possess them. One of his eyes contains a sesshōseki. He was later killed by his resurrected mother, before Izuna could avenge Yomi. He wanted to expose the world they live in to the public, in a way he succeeded since the kyuubi was seen around the world.
Lord Tamamo
The successor to the Kyuubi, she is the mastermind behind the sesshōseki-related incidents that have occurred, and Kazuhiro's overlord. She used to be a demon-user who became an evil spirit of incredible power after death. She is first identified in chapter 19, when Kazuhiro removes Kagura's and Kensuke's souls and takes them to Tamamo Garden. When Kagura attacks him, Tamamo intervenes and reveals herself. Tamamo tells them to fight and search for the ten sesshōseki, and that the one who collects them all will control the Kyuubi, and be its true successor.
Lord Tamamo doesn't seem to have a discernible personality, and appears quite inhuman.
