Benio Adashino

Benio Adashino (化野 紅緒, Adashino Benio) is the main heroine of Sousei no Onmyouji, she is the head of the distinguished Hondo-Adashino family from Kyoto. Together with Rokuro Enmadou, they are the current Twin Star Exorcists, destined to have a child who will be the Miko.

Appearance
Benio is a short girl with waist-long hair and green eyes. She used to have 2 purple bobble hair ties on both sides, before replacing them with a pair of Japanese bellflowers shaped hair pins that were given to her by Rokuro.

She later loses her legs which are then replaced by impurity legs (like Rokuro's arm).

Personality
Benio is not very talkative and in reality dislikes talking. She loves eating ohagi and absolutely hates sharing them with someone. She also has a strong sense of pride, not wanting help from others.

Past
When Benio was young, she was raised 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. Later on, it was shown that she cried heavily at their funeral.

4 years later, Benio lost her brother Yuuto 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. As a girl living in Kyoto, she attended middle school normally, and was idolized by many students because of her good grades and performance during physical education. Before long, she and her grandmother were assigned to move to Tokyo, and she had to leave her old life behind.

Present
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.
