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.
Thearesia is described as a person who loved flowers more than swords. However, she was willing to use the sword in order to defend her loved ones.
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.
