Izumo Kamiki (神木出雲 Kamiki Izumo) is a female student at the Exorcism Cram School of True Cross Academy. She is strong-willed, and something of a "tsundere". She comes from a long line of shrine maidens, and was born with Heian Period noblewoman-like eyebrows. Although a top student, she is quite condescending towards her classmates, both in actions and words.
Izumo has dark red eyes and long dark purple hair, which she usually keeps in a twintails or a ponytail hairstyle. Her most notable trait would be her small, oval shaped eyebrows, which is why Rin Okumura calls her by the nickname polkabrows. Her outfit is primarily the school uniform. She has also been called "cute" by Yohei.
Izumo maintains a very tsundere attitude most of the time, though it's mostly tsun and less dere. She is very cold and condescending towards those around her except for her friend Paku. She takes advantage of Shiemi Moriyama, when Shiemi asks to be her friend, by essentially making Shiemi her servant. Paku, distraught that Izumo was taking advantage of an honest person, finally admitted to Izumo that she does not consider Izumo to be a true friend. However, she does occasionally show kindness. She was the first Exwire to accept Rin after learning that he was the son of Satan. She sat next to him on the train to Kyoto when no one else would. In the anime, she encouraged him on his candle training when he was frustrated. She is quite considerate even though she does not appear that way. She easily loses confidence when she sees her friends in distress but has slowly learned to stay calm and composed during battles.
Izumo was born in Inari, a sacred land that had been under the protection of the White Foxes for generations. Izumo was a member of the Kamiki family, a family of mediums whose purpose was to quell the Nine-Tailed Fox Spirit, a powerful Demon that was sealed within the Life-Taking Stone, which had the power to revive the dead and kill any who approached it. Because her family had interbred with the White Foxes, Izumo was born with demonic blood, but over the centuries the Demon blood line had become so thin that there was now no difference between Izumo and a regular human. Izumo lived in the Inari shrine with her mother Tamamo and younger sister Tsukumo. Tamamo was the head priestess of the Inari Shrine at the time, and was charged with appeasing the Nine-Tailed Fox Spirit through a dance known as the Divine Summoning. Because of her Demon blood Izumo was able to see Demons while others could not. This caused her to be isolated for most of her childhood and, with the exception of Paku, grew up with no other friends. This caused Izumo to be distrustful of other people and she convinced herself that she could not rely on anyone.
One day, while Izumo was attempting to imitate the Divine Summoning, she was approached by a strange short man named Michael Gedōin, a woman, and two other gentlemen dressed in black. Maria said that they were from an organization known as the Illuminati. She then revealed that she was able to see the White Foxes, much to Izumo's shock, and said they came to research the Life-Taking Stone and asked if she could talk to Izumo about it. Izumo was suspicious of the group and refused, but before she could leave, Maria gave her a card with Maria's name and number and said if anything happens to call them. Soon after Izumo began to notice a change in her mother's behavior and began to grow concerned. Her suspicions were correct when one night she discovered her mother had been possessed by the Nine-Tailed Fox Spirit, who then tried to kill Izumo and Tsukumo. The White Foxes protected Izumo and Tsukumo, giving them a chance to flee. Hurt and desperate, Izumo contacted Maria and the possessed Tamamo was captured and Izumo and Tsukumo were taken into the Illuminati's custody under false promises of protection, unbeknownst to them their mother was being brutally tortured and experimented on.
After ten days in captivity, Izumo woke to find Tsukumo missing and was told by a remorseful Maria that she had put Tsukumo up for adoption in order to protect her. She then told Izumo to wait for her to come back so they could escape together, but Izumo refused to trust Maria and tried to escape on her own. She was quickly caught and Maria was mercilessly executed in front of Izumo for her treachery. After witnessing the Illuminati's cruelty, Izumo agreed to do whatever they asked of her as long as they left Tsukumo alone.
True Cross Academy arc
After brief appearances, Izumo is officially introduced when Shiemi want to befriend her and Paku. When Shiemi tries to talk to her and falls to the ground, Kamiki just comes out and calls her an "idiot". During class on Magic Circle with Igor, the class is explained the basic requirements to become a Tamer and are then welcome to find out if they have what it takes. Izumo readily invokes both Miketsu and Ukemochi at once, earning praise from her teacher and classmates, who were without this natural talent. Izumo also became shocked to see that Shiemi also has the talent to be a Tamer then summon a Greenman.
Shiemi again chasing her to try to be her friend, Izumo became annoyed, but accepted after a while believing she could make Shiemi her slave. To prepare students for the Exwire-test, Yukio organizes a camp to prepare them in their dorm, similar to an abandoned building. There, Izumo decides to bathe with Paku, again being followed by Shiemi, but Izumo does not allow her entry, claiming that if she was her friend, she would understand. As always, Shiemi respected, but this behavior disappointed her friend Paku. When Paku reveals she was quitting the course of exorcists, for failing to follow the lessons, the two are suddenly attacked by a Ghoul.
While Paku has been seriously injured by the demon, Izumo summons her familiars to save them. Unfortunately, instead of listening to her orders, the Byakko turn against her because of her mixed feelings. Rin Okumura arrives in time to protect her and tells her to tear the paper contract, making her familiars disappear. Shiemi came soon after and told Rin to keep the Ghoul busy while she took care of Paku's injuries. With the help of Yukio and the others, the Ghoul fled and Rin finds Izumo hiding and crying because she felt useless by not being able to protect Paku. Rin gives her his shirt and tells her to hurry up and go. She later thanks Rin for saving both her and Paku.
Training Camp arc
Izumo and Shiemi drew the magic circle while watching the boys build their tents. Shiemi, being somewhat anti-social in most of her life, called the boys "strangers." Izumo says Shiemi is only strange in this, remembering when Shiemi and Paku went to her despite how Izumo scolded her. As Shura is resting in a tree, she is surprised at how quickly the girls are able to do the drawing. Shura is called out on her laziness. Completing the painting, the girls start cooking dinner. Izumo, who is not a good cook, like Shiemi, is replaced by Rin, who makes a feast for all and the group was surprised with the culinary skills of Rin.
When the test to capture Stone Lanterns was about to begin, Izumo commented that she liked the idea of having only three lanterns, and therefore three places for them, making the whole group rivals of eachother. When they began the exam, she called Mike and Uke to help. When Rin, Shiemi, Ryuji, Renzo and Konekomaru returned to the camp, they found that Izumo and Nemu Takara had already taken their torches, and Izumo cited that Takara was the first to succeed.
When Amaimon attacks the camp of Exwires, Izumo shows fear, knowing that Amaimon is one of the Eight Demon Kings and is bathed with holy water along with the other students (except Rin for being half-demon). Shura also ordered them not to leave the inside of the protective barrier, but after the start of the showdown between Rin and Amaimon, Ryuji becomes mad and also joins the fray, followed by Renzo and Konekomaru. Izumo uses words to make them stop, but they ignore her and continue, causing her to call them idiots in your head.
Impure King Revival arc
On the trip to Kyoto, Izumo sits next to Rin at the train to the Shinkansen. After Shura explains their mission in Kyoto, Rin asks Izumo if she was afraid of him for being the son of Satan. Izumo replies that there are many people in this world related to demons, and she was not afraid of him, and berates him for making something small into a storm in the teacup. As Rin claims that Izumo is a friendly person, causing her to become embarrassed. When he also called her "eyebrows", she demanded that he called her by her name. So Rin thanks her with her name without prefixes (which in Japan indicates greater intimacy with the person referred to), leaving her blushing, but despite this, she asks him not to call her without the honorable titles. Izumo then becomes more aggressive in their argument, calling people fighting the good of others but who flee in difficult times (referring to how the others were treating Rin). Ryuji then gets angry and raises his voice against her, cursing her then.
Thereafter, Exwires are punished by the angry Shura with Bariyons again because of Ryuji and Izumo. When the two start bickering again, Renzo notices movement out of his eye corner. Shiemi is attacked by an older Bariyon. Attempting to help Shiemi, Rin causes a fire with his flames, forcing Izumo to use holy wine to put the flames out.
Terror of the Kraken arc
Izumo is seen with the group when they are on the beach trying to have fun and relax.
True Cross Academy Festival arc
After having a nightmare about her past, Izumo wakes up in a room, completely alone. Soon after, several members of the Illuminati, including Gedōin and Renzo, arrive to meet her. Renzo greets her, and informs her that she is now in the Illuminati headquarters.Then, to her shock, her mother is wheeled into the room. As Tamamo weakly pleads with Izumo to save her, Gedōin says that Tamamo's body is no longer useful for experiments, and thus the Nine-Tailed Fox must be transferred to Izumo's body. All the Illuminati then leave, save Renzo. After Renzo cheerily tries to start a conversation with her, she slaps him, angrily stating that she thought he was like the others. Renzo, unfettered by her backlash, replies that he always thought she was like him, and leaves. Izumo looks at her sister's doll, thinking about how she is like Renzo, a traitor.
Later, Izumo is brought to a testing room by a group of Illuminati soldiers. Along the way, she begs them to spare her and talks about how she might be injured or hurt. As they are about to perform the experiment on her, she manages to escape and summon Mike and Uke, who reveal that her friends are here to save her. They are soon stopped by Renzo, who easily defeats the White Foxes, much to Izumo's dismay.
Izumo, is then led, wearing handcuffs and a ceremonial dress, through the area where her classmates were fighting against the chimera zombies. Rin manages to beat back Renzo and get to the platform. He offers to help her get free, but Izumo, remembering her past, and believing how it was wrong to rely on others, shouts at him to get out of the way, and leaves him. She is then forced to invoke the nine-tails from her mother. Although she believes she is successful by the end of the dance, Izumo soon becomes overwhelmed by the nine-tails. As she struggles to regain control, she remembers all of her classmates, and how she loved them. Rin then breaks into the room with a massive explosion, and goes over to help her. Izumo asks him why he is risking his life for her, and he retorts that he couldn't let her die, as he attempts to carry her and her mother out of the room. Izumo is soon completely possessed by the nine-tails, and attacks the others. Fortunately, Tamamo manages to put the nine-tails into her control, at the cost of severely wounding her. As Tamamo lays dying, Izumo asks her why she would do this. Tamamo then replies that is because Izumo is her little treasure, making Izumo cry and ask if she was wrong. Tamamo answers it's alright, because everyone is by her side, including Tsukumo, Mike and Uke. After Gedōin transforms, her familiars unexpectedly appear. With her familiars, Izumo manages to defeat Gedōin. Everyone is then rescued by the Kyoto Branch of the True Cross Order.

Powers & Abilities
She has proven to be a skilled Tamer. She believes that her natural talent is related to her distant relation to the White Foxes. That means she has exceptional spiritual strength, as Igor said that this is the key to controlling familiars. Her knowledge and use of their skills is also impressive. She can use them to fight, and can also use them to summon the sacred wine and remove a Ghoul medium level.
She most often summons Mike and Uke, two chibi-like foxes whom she calls her Brothers. She claims that they are strong, despite their size, and supposedly it was they who carried the Stone Lantern in training camp. With their help, she was able to pass the Exorcist Exam alone, while everyone else (except for Nemu Takara, who also went by unknown methods alone) had to join as a team to pass.
