Theresia van Astrea

Thearesia van Astrea (テレシア・ヴァン・アストレア) was the former Sword Saint and Wilhelm van Astrea's wife.

Appearance
She was tall and had long red hair with flowers attached to it, blue eyes and a white complexion. She used to wear a white dress when operating as a knight of the Royal Guard, while in her free time she wore a green and white dress

Personality
The hero of civil war, Thearesia was described as an open-minded sociable person who had a fatal flaw of shoving aside her own personal feelings while only focusing on that of others. Despite her immense talent and lineage she never wanted to be a swordsman and take up the mantle of the "Sword Saint". However, certain circumstances forced her to resign to her fate in other to end the civil war and protect the love ones she had left. This eventually led Wilhelm to "take" the sword from her and free her from a life of bondage by duty. Thearesia was avid flower lover and could be found viewing them in ruins where she and Wilhelm routinely met in her spare time. She went missing while fighting the White Whale 14 years ago and is presumed dead.

Abilities
Sword Saint (剣聖 Kensei): Thearesia became the Sword Saint when she was 12 years old.

Divine Protection (加護 Kago): As the Sword Saint, Thearesia had many Divine Protections, however she was born with the Divine Protection of Shinigami (死神の加護 Shinigami no Kago). Slashes imbued with the Divine Protection's power leave wounds that are unable to be healed. The power of the Divine Protection increases the closer she is to the target, and she can even reopen wounds others have if they are close enough and were originally inflicted by her.

Master Swordsman: Thearesia was highly skilled at using the sword.

Equipment: As the Sword Saint, Thearesia wields the Dragon Sword Reid (龍剣レイド Ryuuken Reido). The sword can only be drawn against opponents it deems worthy for it to be used against.
