Benio Adashino

Benio Adashino (化野 紅緒) is the main heroine of Twin Star Exorcists series. She is the next head of the Adashino House, one of 64 most important houses of Tsuchimikado Island. She and Rokuro Enmado are the current Twin Star Exorcists, and is destined to have a child who will be the Miko.

Appearance
Benio is a teenage girl around average height and green eyes. She has waist-long black hair (dark purple in the anime) that has a set of long bangs that frames her forehead. She is usually seen in her school uniform or exorcist gear. She used to have two pink bobble hair ties (given by her brother Yuto in anime), on both sides. She later replaced them with a pair of silver Japanese bellflower-shaped hair pins that were given to her by Rokuro.

During their fight against Yuto, she loses both legs and gets impurity legs as replacements, much like Rokuro's right arm.

Two years later, she is shown to have grown taller, however her breasts were still quite undeveloped.

After her transformation to Taiyin, as a humanoid impurity, she has her kuji-kiri on the stomach, dark skin, golden eyes and light-colored hair like other impurities. She has a single horn on her right side, and a long mantilla on her hair. The hair pins given by Rokuro are transformed into neck and head decorations.

Personality
Benio first comes off as a cold, quiet person, who dislikes talking and is easily irritated. However, regarding exorcism she is very passionate and can be very talkative. Since she comes from an important family, honor and pride are both very important to her. She is also very competitive, especially around Rokuro, and since she was taught to never back out from her words, she can be pretty stubborn and will use any argument to win.

After warming up to Rokuro, Benio is shown to actually be a very caring person. She is also easily embarrassed, even to the point of fainting when she's extremely embarrassed.

She also really loves ohagi, and is even prepared to make an anime adaption of ohagi man, a hand-drawn manga based solely around ohagi.

After two years, Benio seems to be able to show her feelings comfortably compared to when she first met Rokuro, and seems to show her jealousy more openly than before.

History
Benio was born raised in Adashino House on Tsuchimikado Island to learn and practice exorcism for her future as an exorcist and lived a happy life, until a powerful impurity defeated her parents at the sight of her own home. This Basara proceeded to ask her whether she wanted to save her mother or her father, and when she could not answer, asked her parents whether they wanted to save themselves or their daughter, to which they answered without hesitation, orphaning her on sight in front of her. Then later, it was shown that she cried heavily at their funeral.

Four years later, Benio heard her brother Yuto disappear in the Tragedy of Hiinatsuki Dormitory, furthering her emotional pain.

Before the events leading up to the beginning of the story, Benio had trained herself to become an exceptionally powerful exorcist, wielding her late mother and father's weapons. She later moved to Kyoto to live with her relatives of Adashino House and attended middle school normally. Before long, she and her caretaker Kinu were assigned to move to Tokyo, and she had to leave her old life behind.

Plot
Benio was first seen falling from the sky after exiting Magano, into a river. Rokuro tried to save her, but she ended up saving him from the river. She asked him to help on getting to the place from 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. Inside Magano, she fought multiple impurities and defeated them, but was then surprised that Rokuro followed her. As she helped healing the wound of one of the children, 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 went to defeat the Impurity. She gave her all against that Impurity but wasn't able to defeat it and as she was about to be defeated, Rokuro stepped in and used a black charm, transforming one of his hands and defeating the Impurity with a single blow. This annoyed Benio, as she stepped on Rokuro foot after that and told him that she didn't asked for his help.

As they left Magano, outside they met Kinu, a woman that takes care of Benio. Before leaving 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. In the anime version of the series, Benio and Rokuro had to move into a very big villa.

Benio has lost her enchanted powers, due to the battle between her guardian and Sayo's guardian.

After losing her powers, Benio was attacked by impurities. Without any abilities, she was under the risk of dying until Kamui saved her.

Other Abilities
Esoteric Buddhist Mantra: With this mantra, she is able to heal wounds by chanting "Abira, Unken, Sowaka".

Rokuro Enmado
Benio dislikes Rokuro when they first meet, because he is more powerful than her but dislikes fighting, something she considers unacceptable and selfish for an exorcist.

After they are told that they are the Twin Star Exorcists and will have to marry and have a child, she opposes the idea considering him a disgrace as a partner due to his lack of sense of justice. However, after seeing him fight to protect others, she starts to accept him as an exorcist and motivates him to become one again. When they learn of each other's dark pasts and start fighting together, they start understanding and becoming more comfortable with one another. After the fight with Yuto she already seems to like him, though she herself is unaware of her feelings.

After the time skip, both seem to have become even closer. They bicker less and behave in a much friendlier way, even being told by others multiple times to stop flirting in public. She is even openly jealous when Rokuro is approached by other women. In chapter 33, it was revealed that she has indeed fallen in love with Rokuro and they shared their first kiss.

Kamui
A powerful Basara that murdered Benio's parents at age 8, which completely changed her life. She encounters him again eights years later, though despite the progress she had made is still no match for Kamui. Rokuro intervenes in time to backup Benio. Regardless, of their combined strength wasn't enough to overpower Kamui, he albeit is impress to spare them and wishes for another challenge when they become worthy eventually. Ironically, Kamui steps in giving Benio a helping-hand when her legs got severed by her traitorous brother and replace them with impurity ones. Despite their antagonistic relationship and forbidden exorcist-impurity association, they desperately search for the very first impurity.

Kamui is the one enemy (besides Yuto) that Benio really wants to defeat.

Yuto Ijika
Originally, Benio admired her older brother, and greatly looked up to him, a fact proved by her wearing the hairpins that were gifted to her from Yuto for the longest time. Through flashbacks, it can be seen that Benio had always tried to become like her brother - at least what she perceived of him (a kind, strong, and virtuous exorcist). When Yuto revealed that he was behind the Hiinatsuki Tragedy, and that his kind demeanor had been a façade, Benio was utterly heartbroken, and gradually came to hate Yuto. Benio was so ashamed of Yuto, that she apologized to Rokuro by bowing to him and crying out for forgiveness on behalf of the Adashino Family.

Benio now recognizes Yuto as an enemy, and has put their whole past behind her. However, she did feel sympathy for him after seeing flashes of his visions and understanding that he was driven mad by them, as well as seeing his care for her was real but was twisted by his corruption.

Mayura Otomi
Benio first met her as a new classmate sitting nearby, and later accidentally spotted her in her and Rokuro's new house. After she learned about the truth, the two had a heated discussion about Rokuro being an exorcist again. Benio is somewhat envious of Mayura's chest size and asks the latter about it. Despite this and the fact that they both like Rokuro, it doesn't get in the way of their newly developed friendship. Later when Mayura was turned into a fallen impurity, Benio, like Rokuro, was determined to save her.

During the two-year time skip, Benio, alongside with Rokuro, helped her with the training to become an exorcist.

In the fight with Hijirimaru and Higano, Mayura gained her power as a Guardian, for the sake of protecting her, Sayo and others. After she was exhausted, Sayo did the identification ceremony to awaken Benio's power. Being the only one who witnessed Benio's impurity form, she was shocked but still thought she was a human.

At the airport, when she and Rokuro were heading to the Tsuchimikado Island, Benio told her she would be strive to regain her power. She seemed pleased and told Benio that this would make her more motivated.

In anime, Mayura was fond of Benio from the very beginning and was the first person Benio opened up to and was her first friend. They share a very strong bond and trust each other completely. Mayura is constantly worried about Benio's well-being whilst she is in Magano and admires her courage.

Trivia
