Mayura Otomi

Mayura Otomi (音海 繭良) is the daughter of Seigen Amawaka and Yukari Otomi and close friend of Rokuro Enmadou and later Benio Adashino.

Appearance
Mayura appears to be same height as Rokuro and Benio, she also has slender figure like Benio. However, she is more busty than her. She has yellow hair which from her father that fades into a green color which from her mother, along with blue eyes. She's usually wearing her school uniform, but later wearing casual clothes. She resembles her mother, Yukari.

Personality
Mayura is a kind and caring person, as shown when she was afraid of Rokuro becoming an exorcist again for she knew how much he detested it. Much like Benio, she likes Rokuro, and as always he is oblivious to the fact. She also accepts the fact that he and Benio work and live together.

Despite being a usually happy person on the outside she tends to keep her true feelings bottled up. She also tends to easily get down on herself and negatively compare herself to others. As noted by Rokuro, Benio and her father, Mayura has a habit of saying strange expressions or insults. When this habit was mentioned to her, Mayura claims to have no control over it.

She is very timid as said by Seigen, her father. Due to her being timid, she is unable to become a "good" exorcist. She was also unable to bring herself to slay Impurities when she first became an exorcist.

However, when she stopped being timid due to Sayo being saved, she became much stronger and braver. As shown she decided to join her father in order to protect Rokuro and Benio.

It is shown directly in the anime that Rokuro does care for her, but has no visible feelings. Although with Benio, that is a different story.

Plot
First introduced in chapter 6, Mayura is Rokuro's childhood friend and the daughter of his sensei, Seigen. It's shown early on that she has a crush on Rokuro that he is completely unaware of. She is shown to be clumsy but she is true to her own emotions.

While she at first was against Rokuro becoming an exorcist, having seen how broken he was after the incident, she yells at him saying that she doesn't want to see him in such a sad state ever again. This lead to an argument between Benio and her concerning Rokuro's safety. He ends the argument between the two when they asked him what he wanted, to which he responded that "If there's something I can protect, I want to protect it.". He adds in that even if he died while fighting, if it were an atonement to everyone who died, he'd be fine with that.

Angry and sad, Mayura leaves the two alone. She however left behind her charm, which Benio recognizes its usage to keep impurities from sensing high levels of enchanted powers. Mayura was captured by an impurity but is saved by Rokuro. Afterwards, she eventually realizes Exorcism and fighting Impurities is where he belongs.

In Chapter 8, as she is walking home from school, she meets up with her father, Seigen Amawaka. They are later shown to be sitting in a restaurant. After asking about her mother, Seigen asks her how long is she going to call him 'dad' as he is hardly ever around. This prompts her to say that both her and her mom knows the work that Seigen is doing, and she is shown to respect that. Soon, Seigen leaves her with a warning to not get involved with Rokuro anymore as he is "fundamentally different from us".

She then finds Rokuro who is feeling down because Benio found that he was the lone survivor of the Hiinatsuki Incident. He asks if there is nothing he can do as an exorcist, to which Mayura retorts that he is a little drama queen and chops him on the head. Shortly after she cheers him up, she turns into a fallen impurity in front of him.

Seigen and Benio catch up to them, and Seigen asks the two to leave as he is going to exorcise Mayura. He laments that he was not able to do anything that was remotely fatherly for her. As they both fight, Benio and Rokuro noticed that they can hear Mayura's voice, albeit faint and fading. They inform Seigen and together as the twin star exorcist, they purify Mayura.

In the aftermath of the battle with Yuuto, Mayura becomes distraught that both Rokuro and Benio will leave her to go face increasingly dangerous foes. This leads her to begin training as an exorcist over the two year time skip with Rokuro and Benio, her father would also pitch in on occasion. In this time, she becomes closer to Benio as a friend.

After the time skip Mayura is still unsure of herself and her father blatantly tells her that she probably doesn't have what it takes to be an exorcist. When she was training she runs across Shimon Ikaruga, and he scolds her, saying that the only person who brings Mayura down is herself. He reveals to her that Chiiko, the host of Kuzunoha will not live a long life due to the strain of Kuzunoha's powers. He asks Mayura if what she believes in is so difficult that she can't do anything about it. Mayura yells that she doesn't want to be reprimanded by him. Still Mayura wants to protect her friends and seeks help from him, who after some convincing agrees to train with her.

During the Sayo Rescue Arc Mayura is given a charm by her father that allows her to summon Byakko the White Tiger. Initially, Seigen was asked to go by Shimon, but he turns to his daughter and tells her that the world of exorcism was not one where you can have one foot in. She needs "to find the resolve to step both feet in right now."

When Rokuro and Shimon are battling Basara level impurity Hijirimaru, his partner, Higano went after Sayo, who was placed with Mayura. She tried to hold her own against him, but failed and was mocked by him, stating that she wasn't worth killing. Benio tries to intervene, but was knocked out by Higano. Mayura, frustrated with her inability but still determined to protect everyone, calls upon a barrier to contain both Higano and herself, to prevent him from harming Sayo and Benio.

In the barrier, she casts a curse upon herself to ensure that should Higano touch her, he would be cursed as well. In retaliation, Higano casts lightning towards her, which was what Mayura was counting on. She casts another shield around herself, which reflects the lightning attack from her, inside the shield and towards him. Her plan however, fails to incapacitate him long enough for her to both shield Sayo and heal Benio. He taunts her by threatening to burn Benio's body to crisp, as Mayura shouts at him to stop. Byakko appears before her, and introduces himself to Mayura. She asks of him to lend her his strength, and thus with his power Mayura becomes her father's replacement among the Twelve Heavenly Commanders.

Later on in the battle, Mayura is shown to watch in horror as Benio is surrounded by the miasma of Magano, and watches as the awaken Benio fights Higano. When Sayu is taken away, Mayura stayed to protect Benio who has once again fainted, until the head exorcist arrives. She pleads for him to save the rest of her friends. She is there to witness Benio getting attacked by Sayo's guardian, and afterwards, runs to hug Rokuro and regroup, her father watching her from afar with Arima.

In the aftermath of the rescue, Mayura helps Rokuro set up a small party for Benio, in celebration of her release from the hospital. She is with him when Shimon and Sayo announced that they will be leaving for Tsuchimikado Island. She leaves Rokuro alone, stating that she has other matter's to take care. She is then later shown to be holding a letter of resignation from school in front of her mother.

Powers and Abilities
Magical Prowess: She was told to be a "prodigy" in magic for exorcism use. Her father, Amawaka Seigen, praised her for memorizing long spell enchancements. She is implied to have strong enchanted power, albeit untrained. Benio believes that she might have stronger enchanted power than Ryougo.

Enchanted Gear: Barriers and spells tend to be what she is best at, to the point that even a Basara level impurity has trouble doing actual damage to her. In addition, she is shown to be capable of casting curses as well, as shown in her fight with Higano.

White Tiger: She gains the spirit of the white tiger from her father and with it a powerful fighting form. Heavenly Commander Byako showed himself when Mayura was fighting against Higano, the 9th Basara and in the process grants her Byaku Ren Kohou. Here she gains huge claw like weapons that covers her entire arm, and attacks by making large slashing attacks, which is capable of slicing apart rocks and the ground itself. Her speed itself seemed to have been boosted as well.
