Yuto Ijika

Yuto Ijika (石鏡 悠斗) is the older twin brother of Benio. He is also an old friend turned enemy of Rokuro Enmado, and the mastermind behind the Hiinatsuki Tragedy.

Appearance
Yuto is a young man with blue hair that is kept in a bowl cut hairstyle, he has gold colored eyes and wore an eye patch over his left eye and is seen wearing a white uniform with dark blue designs on the sides of the sleeves and on the zipper.

Before he had an eye patch, he had blue eyes matching the color of his hair.

Two years later, his appearance has not changed except he has gotten taller with a stronger build.

Personality
When he was younger, Yuto appeared as an antisocial kid who was confident in his own power, who saw anyone else in the Hiinatsuki dorm as low level exorcists. To Benio, he was an example as older brother and had a strong sense of justice. This was later revealed to be a cover for him in order to reach his goal.

In reality, he remains very confident in his own power and he feels nothing for his little sister nor Rokuro and didn't hesitate to kill them if he had the occasion, he is cruel and fearless in front of his enemies. He is ruthless and shows no remorse in his actions and even belittled Benio by insulting their late parents who sacrifice themselves to save her while calling her pathetic. He also loves showing off his strength and whenever he has a moment of weakness, he makes it appear like it is a bluff in order to keep his strong image. He does not mind sacrificing countless people to become the strongest exorcist.

Plot
In both the manga and anime, Rokuro and Yuto were friends living at Hiinatsuki Dorm. They were considered to be the exorcists who ends the war with the Impurities. On the day of the Hiinatsuki Tragedy, he and Rokuro fought it out resulting in Rokuro's corruption and Yuto's disappearance. Rokuro meets Yuto again after he is forced to confess to Benio about the truth behind the tragedy. In the anime, Rokuro is shown to have lost his temper and attacked Yuto relentlessly, while in the manga, Mayura was corrupted before Yuto met up with Rokuro. Considering that the Furu no Koto drains their spell power, Rokuro couldn't put up much of a fight in the manga. In the anime, Mayura was corrupted before Yuto's second meeting with Rokuro. Yuto then asks Rokuro to side with him in order to complete his ambition. Rokuro and Benio have been training to fight Yuto (they still have to give each other a signal to activate Resonance). In both the anime and manga, Kamui turned Benio into a Fallen Impurity and she also proved that she could utilize her power enough to land multiple hits on Yuto leaving him bloodied and battered. Later, Rokuro healed himself somehow. In the manga, Rokuro's future child, the Miko, has a chat with him and gives him his spell power so Rokuro gained a new form. In the anime, this was cut out and the transformation only lasted long enough to heal Rokuro's wounds. Working together, Yuto was defeated, however it was a hollow victory as he escaped before telling Rokuro that "I'm going to the island".

Sometime later, he stands among the bodies of fallen exorcists before he believes that he faintly felt Rokuro's presence and wonders how he long he has to wait for him.

When Tenma Unomiya telepathically contacts Rokuro, Yuto manages to detect it before the latter cuts off the connection after realizing this. Now aware of Rokuro's presence on the island, Yuto screams out in joy as he manically laughs at the thought of fighting against Rokuro again.

Powers and Abilities
Yuto is very skilled in exorcism having been a skilled prodigy at a young age. He studied forbidden exorcism in order to increase his power and was successful as his new abilities allowed him to greatly wound and manage to defeat Seigen Amawaka, who at the time was still a Twelve Guardians. Yuto even said he couldn't believe he was able to become stronger than his old teacher in a short time. Yuto's threat level increased to that of a Basara and its said Rokuro would have to join the house of one of the Twelve Guardians to fight Yuto again. Single-handedly, Yuto was able to take down several trained exorcists on Tsuchimikado Island and emerge without a scratch.

Kegare Form: Being an Exorcist that has Kegare powers, Yuto is able to use Enchanted Gears to help him combat Impurities when fighting in Magano. His Enchanted Gear takes the form of a rocky Blue arm similar to that of an impurity. Yuto is also able to perform a full-body enchantment akin to the Twelve Commanders Celestial Gear Equip.
