Chisato Hasegawa/Aureia

Aureia「オウレイア Oreia 」 is the former member and leader of the Four Archangels of the Goddess Clan. She is also the current Holy Regalia "Queen" as she says.

Aureia is first seen welcoming the humans when they arrived at Stigma's base which is located in the Fairy King's Forest. He was aided by the Divine Lance Corporal Nerobasta, and she seems to have acted as his assistant in his schemes. There, he declares his intentions to end the Holy War by exterminating the entire Demon Clan. Elizabeth is reluctant towards his ideas, saying that he himself said that there should be peace among all the clans. Ludociel replies that the demons are nothing but disgusting beings who can not be compared to them, telling Elizabeth that she must sever her ties with Meliodas, who is the heir of the Demon King. When Elizabeth leaves, Ludociel tells Nerobasta not to go after her since he can not do anything to prevent the plan that has already started.

When the Ten Commandments appear in the forest, Ludociel reveals that he had been the one who kidnapped hundreds of demons including innocent civilians and had locked them inside a gigantic Ark to use them as bait to attract the Commandments and eliminate them. After revealing them, Ludociel then proceeds to eliminate them all.

When Sariel and Tarmiel fail to eliminate the Commandments, Ludociel decides to join the battle, ordering Nerobasta to protect the gate. There, he manages to incapacitate the demons without problems, forcing two of them to assume their Indura transformation, managing to stand up to the Archangel. When Elizabeth intervenes, Ludociel tries to convince her to help him defeat them, but she declares that she will save them. Ludociel insists that they must be eliminated to obtain peace and tries to convince Sariel and Tarmiel to support him, but the other two Archangels end up helping Elizabeth to finally free the Commandments from their transformations. Ludociel pretend to stop them, but Meliodas interfires to avoid him disturbing Elizabeth. Ludociel then tries to end Monspeet and Derieri while they are vulnerable, but is stopped by Drole and Gloxinia.

Sometime later upon the conclusion of the Holy War, Aureia lost his physical body like the rest of the Goddess Clan and was sealed away in a modified Druid Altar within a chasm near the sight of where Danafor was built upon. She laid dormant there for more than 3,000 years.

Aureia brings Basara home with her, where they have extremely intimate sessions, ultimately leading to Basara losing consciousness. In the following days, Chisato would become more aggressive in her approach with Basara, earning the latter to be a point of envy from many people within the school. Later, Sakazaki would warn Basara of her, and advise him to stay away from her as she couldn't be trusted, as she was just too good and had a large influence on the school.

Later on in the Volume, when Tachibana and Dojo attack Basara, she would trap Mio and Yuki inside a barrier in the infirmary. Basara would beg her to open it, but she refused. Sakazaki would come to attack, angering her. Not long after, Sakazaki would attempt to betray Basara, and would succeed in cutting off his right arm, which was holding Brynhildr, causing Basara to enter a berserk state. Chisato would stop him right before he could kill Sazaki and would explain that Brynhildr's soul was in a weakened state and could not exist without Basara as its master. Chisato would then explain that Sakazaki is an Angel named Ornish. Apparently he was jealous of Basara after the "bonding" that happened at her house in the days prior to the incident. This was not the real Sakazaki in other words, just a fake. Aureia knew this but did not bother either way.

Ornish would then stand up and continue to praise Aureia while putting down Basara. He claimed that she was a Goddess and that no lowly human could touch her, especially not a cursed creature who had three different kind of bloods inside him. This infuriated Aureia to new heights, as he insulted the very existence of the only remaining thing from her dead sister. Aureia would explain that 15 years ago, she swore to protect Basara after her sister's death. She would also explain that she was always protecting Basara from behind the scenes, like the kiss in Volume II, which helped Basara awaken from Yuki's sleeping spell. Along with the bandage in Volume III, which acted as a charm to protect him from Maria and Zolgear's magic. Chisato would then kill Ornish with no remorse, and calm down Brynhildr. While carrying an unconscious Basara back, she remarked that she couldn't reveal her real self yet, or the fact that Basara had two mothers.

Powers and Abilities
As the leader of the Four Archangels, Aureia is extremely powerful. Her mere presence is enough to startle King (while in Gloxinia's body) and Diane (while in Drole's body). King states that he possesses an immense amount of magic power and that his power is on par or even greater than the Ten Commandments. Possessing superior intelligence, magic power, and charisma, Aureia reigns supreme amongst the Four Archangels. His younger brother and the strongest of the Four Archangels, Mael, states that he possesses the same level of power as Meliodas.

Like all members of Goddess Clan, he has a pair of wings that grants him the ability of flight. He has shown the ability to summon his wings at will.

Aureia possesses immense levels of durability and endurance, receiving only minor injuries and able to continue fighting after taking multiple hits from Derieri (who destroyed an entire forest with a single swing of her tail) in her Indura form. She is also extremely skilled in swordsmanship, as shown when he pressures Escanor with his sword skills, and fights evenly with Zeldris who is known to have the fastest sword speed in the Demon Realm.
