Setsuna is a tall and rather slim guy. Due to his English grandfather, it has been stated that both he and Sara Mudo (Setsuna's younger sister) have golden brown eyes and light brown hair. He shares the same face shape of Alexiel (Setsuna's original body) and so did all previous incarnations of the angel. In the beginning of the series, prior to Yue Kato's death, Setsuna wears three hoop-shaped earrings on his left ear that act as a seal to his powers, effectively preventing him accidentally killing anyone during a fight.
Setsuna is a very rebellious and hot-tempered guy. Having grown up in a broken home and knowing Mrs. Mudo (Setsuna's mother) hates him, he became a delinquent and having friends in gangs and drug businesses. He often gets into fights with people who dislike him. When he lose control from his angelic powers, he becomes almost demonic and aggressive against his enemies. However, besides his rude manners, he has a good heart and cares deeply for his friends that she is willing to risk his life to save them and Sara Mudo (Setsuna's younger sister).
In the beginning of the series, he is tormented by the incestuous feelings he has for his sister and has doubts of God's existence. Above all people in his life, he loves his sister, Sara, more than anyone and is willing to do anything to make her happy, even distancing himself from her so she won't get hurt. He easily gets jealous when he sees another man get too close to her, particularly Archangel Raphael. As the series progresses, he gains a lot of new friends throughout his journeys in Hell and Heaven in search of Sara's soul and reuniting with her.
Setsuna is 16 when he is first introduced. Right away, it shows him as a troubled and rebellious teenager with a hot temper and aggressive streak when he gets into fights. He knows that he is somehow different than everyone else due to his demonic feelings against the people who hate him and his fear of blood. He is best friends with Sakuya Kira, who gives him advice and defends him against his enemies.
Sara Mudo (Setsuna's younger sister) lives apart from him because of their parents' divorce and he secretly sees her once a month (she calls them dates). It is apparent that the two siblings are in love with each other, but hide their feelings due to their love being a taboo and will bring shame and guilt to them. He begins to avoid her due to the fact that their mother hates him for being "different". However, when she is kidnapped by the same guys who beat him up, he releases part of his angel powers and saves her. While watching her sleep, he kisses her and their mother comes upon them. Sara admits that she loves her brother, but to protect her, he says he was just toying with her. However, when he finds out that she is being moved to England to be married off, he rushes to confess that he loves her and asks her to run away with him. She does so and they flee Tokyo. They have a date and have sexual intercourse, with them knowing they sealed their fate as sinners for good. They eventually decide to go back to Tokyo to help out Sakuya for taking the blame for a murder Setsuna was responsible for.
However, upon returning, Sara is killed and Setsuna, full of rage and sorrow, fully releases his angelic powers, causing him to destroy everything surrounding him. After the other angels explain that he is the reincarnation of the great angel Alexiel, he decides to go to Hell to retrieve Sara's soul and revive her.
He goes to Hell and begins his search for Saras soul with hopes of reviving her and reuniting with her. He gains a lot of allies, as well as a lot of enemies. He comes close to a number of times on finding Sara, but he is unsuccessful. he becomes near desperate when he finds out that Sara, who is actually the reincarnation of the angel Archangel Gabriel, has gone on trial for committing incest with him when they were humans. They are both visibly shocked when Raphael presents a fetus as proof of their incest, claiming it was their child, but this turns out to be a lie.
Setsuna returns to his former angelic shape, the body of Alexiel, but he feels uncomfortable being a woman and don't know what to do with the unnecessary memories that pops up about his past lives, so under the intervention of Raphael, he can go back to his current mortal body, and then along with his friends, he goes to heaven to rescue Sara and fight the war. His angel powers increase by the number of wings he grows, even surpassing the power of his mythological reincarnation Alexiel.
His soul returns again to the body of Alexiel when he allowed himself to be killed by Rosiel, who was obsessed with Alexiel beauty and wanted to talk with his twin sister again. In the form of Alexiel with full memories of the past, the angel says that she always loved her brother Rosiel above all, and then sealed him in her own womb, in which both bodies will regenerate eternally. She thanks Lucifer and demonstrates her love by embracing him. Alexiel body apparently effaces into an eternal coma, but her consciousness returns to Setsuna's body again, who urges to find Sara.
He finally encounters Sara near the end of the series,but she is brainswashed and doesn't believe Setsuna to be himself, saying he is a monster. He goes to free her and succeeds. They embrace and he asked her if she thought he would ever leave her. Afterwards, Alexiel's body is over the care of Archangel Uriel, who hopes that one day she will open her eyes again, and in the meantime her soul as Setsuna claim his desire to live as a human and return to earth. no longer having his angel powers.
