Rokuro Enmado

Rokuro Enmadou (焔魔堂 ろくろ, Enmadō Rokuro) is one of the main protagonist of Sousei no Onmyouji. He is an exorcist and is the only survivor from the Hiinatsuki tragedy. Together with Benio Adashino, they are the current Twin Star Exorcists, destined to have a child who will be the Miko.

Appearance
Rokuro has messy dark brown hair, with a small ahoge at the top. He is short, has red eyes and sharp teeth. Originally he lost his right arm when he was 12, but due to special circumstances was able to gain a new one.

Personality
In the past he was quite cheerful, having dreams to cleanse and destroy all Impurities and Magano, but after the Hiinatsuki tragedy, due to the fear of losing more "people that he cared about", he decided to stop fighting and quit being an exorcist. He often attempts to become someone big in various areas like: soccer, acting, etc. but he lacks all kind of talent and fails at everything, including simple things as map reading.

Even though he doesn't want to fight, he can't stand by and do nothing when someone needs help, and he is ready to risk his life to help those in need, for example, when he saved Benio from the impurity she had trouble defeating herself, and when he rushed to Magano to save Ryougo, not taking any dangers in consideration.

Rokuro is a bit reckless at times and is very talkative, or, as Benio calls him, "loud". He retains a lot of emotional pain but keeps a strong exterior to make sure none of his friends worry about him.

History
Rokuro was found by Seigen in Magano when he was 6 and had no memory. He was then brought to the Hiinatsuki Dormitory, where Ryougo took care of him. When Rokuro was young, his dream was to become the strongest exorcist and exorcise all the impurities and sins, and by 12 years old he was already an amazing exorcist that was acknowledged by many. One day, one of Rokuro's classmates, Adashino Yuuto, performed a ritual that would transform all students involved at Hiinatsuki Dormitory into Fallen Impurity, causing chaos among the campus. Rokuro himself was caught in the ritual, but rather than becoming a Fallen Impurity along with everyone else, his arm had turned into an Impurity, and a powerful one at that. With no choice left but to put down his fellow friends and students, he killed everyone in the dormitory except Yuuto himself, who escaped into Magano.

Having temporarily lost an arm from the fight as well as all of his friends and classmates, and being the sole survivor of the Hiinatsuki Dormitory, he gave up on being an exorcist, despite being one of the most powerful, and loathes everything having to do with them.

2 years ago
Rokuro used to be a skilled exorcist, training everyday, gaining muscle and fighting Impurities. But ever since the Hiinatsuki incident, in which Yuuto turned all of his friend into Impurities and in which Rokuro was the only one to withstand it, he had to kill all of his friends in order to cleanse them. He fought Yuuto and defeated him too resulting in him being the sole survivor of that night. As a result, Rokuro didn't want to fight anymore nor did he want to be an exorcist, due to the pain of the losses.

Plot
Rokuro was first seen confessing to a girl, but she turned him down, even telling him that there is nothing good about him. Rokuro rushed to Seika Dormitory, where he asked everyone if there was something good about him, but received stupid "good" qualities. As Rokuro was stating his dream, Ryougo and the rest told him he is not good at anything else other than exorcism and that he should become exorcist. This annoyed Rokuro, resulting in him leaving to clear his mind.

As Rokuro was walking outside, he saw a girl falling from the sky into the river and tried to save her, but he ended up needing to be saved by her. She asked him to help on getting to the place on the map she had, but in the end Rokuro wasn't able to find the spot. As they saw 2 children disappear into Magano, she used a charm and opened a portal to Magano to go and save them and Rokuro followed her. As Benio defeated multiple Impurities, a stronger Impurity showed up. She left the kids to Rokuro and gave him a charm to use to get out of Magano, while she defeats it. As she was about to be defeated, Rokuro stepped in and used a black charm, transforming one of his hands after which he defeated the Impurity with a single blow. That annoyed Benio, as she stepped on Rokuro's foot after that and told him that she didn't ask for his help.

After they left Magano, they met Kinu, the woman that takes care of Benio. Before heading towards the place she had to go, she and Rokuro exchanged names. In the end, Benio had to go to Seika Dormitory and when Rokuro came, they mocked him for not being able to read a map to his own place.

Abilities
Impurity Arm: During the Hinatsuki Tragedy,His original arm was devoured by an impurity corrupted trainee, and he eventually got corrupted like the other trainees,but he manage to suppress the corruption and only had his arm regenerated into a rocky red impurity arm.The arm grants his immense power and speed beyond compare and has helped him exorcise impurities with one punch.However,since the arm is Impurity-based, it potentially can corrupt Rokuro again. Enchanted Gear: Being an Exorcist, Rokuro is able to use Enchanted Gears to help him combat Impurities when fighting in Magano. Rokuro has, at two points,briefly become a manifestation of Abe no Seimei after seeing a brief vision of an apparently young girl, implied to be the Miko, who "has finally reached him" while Rokuro asks if she is his "child" during their second meeting before it is cut short.
 * Celestial Gear Expose Charm: Rokuro use this black charm to summon and control his Impurity Arm to perform exorcisms effectively.It is also a seal to disguise his arm into a human arm and prevent Rokuro being corrupted again.Unlike regular Enchanted Gears,it can use unlimited times. After the second fight with Yuuto, his master (Seigen) gave him a red evolved form of his black charm, which gave to the new version of his arm; Astral Disaster.
 * Rekku Madan: Rokuro levitates multiple rocks and places a charm on them, he then fires them at high speed all at once.
 * Ryūsei Sumasshu: Rokuro creates the Wu Xing with his fingers while chanting and punches through the symbol, the destructive strength of the attack is extremely powerful.

Benio Adashino
Rokuro and Benio are destined to marry and give birth to the strongest exorcist, the Miko. At first, he is against this. But after they were forced to live together in order to become closer and accept their given name as the Twin Star Exorcists, he still refuses to accept marrying her. Benio seems to be in love with him even though he is totally oblivious to it. Rokuro has strong feelings to protect her even if it means it would cost him his life. Benio is also seen to show the same feelings. When she lost her legs in an intense battle against Yuuto, she felt very helpless looking at Rokuro fighting and losing which made her resolve to agree to the eleventh Basara Kamui's offer to give her the legs of an Impurity so she can fight again together with Rokuro.

On their first night out, Rokuro gifts two bellflower shaped accessories to Benio as a token of friendship, although the manga and anime heavily imply they are more than friends. Rokuro in the later chapters seems to get embarrassed easily by seeing Benio smile showing signs of attraction. He has also bathed together with Benio as a "challenge", although he passes out from a nosebleed and shock as Benio faints from embarrassment while washing his back. You could easily say their relationship is definitely more than simplistic friends, as they live together (at the forcing of Arima), have bathed together and respect each other as formidable exorcists.

In chapter 33, he and Benio shared their first kiss.

Mayura Otomi
She is Rokuro's childhood friend. She is in love with Rokuro but he is oblivious to it. Rokuro seems to care about her but only because she was there when he wanted someone to be with him during bad times, such as the Hiinatsuki Dormitory Incident, and helped him get back up. She is very worried at first about Rokuro being an exorcist again but soon accepts it. She also seems to accept Benio's and Rokuro's relationship and them both staying in the same house.

In later chapters when she sees Rokuro and Benio together always fighting and becoming stronger she feels left behind hopelessly and starts training with Rokuro and Benio in their house on weekends and saying that she won't let Rokuro and Benio have, as she coins often, "illicit sexual relationships". Determined not to get left behind by the Sousei and saddened by her "low resolve", she becomes one of the Twelve Heavenly Commanders while fighting a Basara, seemingly "inheriting" her father's post.

Seigen Amawaka
An ex-Heavenly Commander who is also Rokuro and Ryougo's exorcist mentor. Rokuro's relationship with Seigen is that of an "idiot disciple" and a teacher. Rokuro (and Ryougo) are seemingly abused by him during his 'teaching methods' and treats them like helpless kids who don't know the cruelty of the world.

His teacher-student relationship with Rokuro becomes rocky as he interrupts (read: saves) the Sousei from being defeated by a strong Kegare, hearing Rokuro's "pretty words" and challenging him to a fight to show his power to back them up. Rokuro loses easily and his black charm is ripped to shreds. Later, Seigen gifts an evolved version of the black talisman to Rokuro after a series of events which involved him losing an arm. Their relationship improves steadily after that.

Trivia

 * Rokuro hates curry due to Benio making curry for 20 consecutive days according to the manga
 * Rokuro's Enchanted Gear is similar to Kamen Rider Double's Fang Memory because of their past slaughter as well as their animalistic look/behaviour.It also bears similarity to the mutation of Piers Nivans from Resident Evil 6,since both manage to retain their minds while regenerated a mutant arm.
 * During Sayo's Divination Ceremony, Rokuro's Spirit Guardian is shown to be somehow related to Abe No Seimei.
