House Astrea

The emblem of House Astrea as worn by Reinhard, bearing the Dragon.

House Astrea (アストレア家, Asutorea-ke) is a noble house in the Kingdom of Lugunica, currently headed by patriarch Heinkel Astrea. They are the direct descendants of the first Sword Saint, contributing to the Sword Saint role and title which they have continued to pass down through generations.

Information

The House of Astrea is among the most acclaimed Houses in the Kingdom of Lugunica. Four hundred years before Natsuki Subaru's arrival, Reid Astrea, the forerunner of the Astrea bloodline, aided the Sage, his apprentice, and the Divine Dragon in defeating and sealing the Witch of Envy. Ever since then, one member per generation has been chosen as the next Sword Saint (剣聖, Kensei), a knight who inherits the Divine Protection of the Sword Saint, which can only be inherited by a member of the Astrea family. Sword Saints are regarded as the Kingdom's greatest weapons and are only called in action when the situation is at the most desperate. Many Astreas and Sword Saints have been killed in action in service of the kingdom, in most recent memory being Theresia van Astrea, who was lost in the disastrous Great Conquest. The current generation's Sword Saint is Reinhard van Astrea.

House Astrea possesses an auxiliary residence in the Royal Capital's Noble District which matches the grandeur of the other mansions located there. In contrast to the appearance of their side mansion, the family itself is not particularly wealthy, nor is their domain grand. The main Astrea Manor is located in the small southeastern town of Hakuchuri, the only fiefdom within the Astrea Domain. It has a modest size compared to the Royal Capital's mansions, the iron gate at its entrance shows signs of age and rust, and the mansion itself reflects the gate's signs of age.

Some members of the household have heavily involved themselves in the ongoing Royal Selection. Wilhelm van Astrea is a member of the Crusch Camp. The Deputy Commander of the Royal Guard, Heinkel Astrea, was a backer of the Priscilla Camp; conversely, the Sword Saint Reinhard van Astrea is the primary benefactor of the Felt Camp, personally working as Felt's knight and protector. As a result of the ideological split, Reinhard and Felt live in the Astrea Manor, whilst Heinkel resides in the Barielle house.

Dragon Sword Reid

The legendary Dragon Sword Reid.

The House of Astrea is in possession of the strongest of the Ten Enchanted Swords, the Dragon Sword Reid (龍剣レイド, Ryūken Reido). The Sword has been passed down through generations ever since the days of the first Sword Saint, Reid Astrea, of whom the sword was named after. It can only be unsheathed by a Sword Saint, thought most Sword Saints have never gotten an opportunity to use it, let alone see the gleaming blade of the Dragon Sword. The weapon was said to be given to Reid Astrea by an unnamed master swordsmith, with the sword's sheathe being covered in golden claw marks which were stated to have been made by the Divine Dragon Volcanica itself. Reid used it to cut down numerous dragons back in his day, though nowadays the sword rarely makes its appearance unsheathed.

It is said to be the most beautiful blade known to man. The blade is abnormally sharp and is nigh unbreakable; Reinhard was able to block Regulus Corneas' Authority of Greed with its sheathe alone. Capable of destroying the world and able to cut through space and mana itself, the weapon is without a doubt the strongest Sword, if not the strongest material item in existence. All in all, the Dragon Sword Reid is the House's most prized and cherished possession, with a rich history and countless legends surrounding it, though no one knows how many of these legends actually hold true to the actual events that transpired all those years ago.

• Heinkel was tasked with attempting to convince Marcos Gildark re-join the knights. Though he failed to do so, Reinhard, who had accompanied his, requested the Divine Protection of Mind-Changing from Od Lagna to convince Marcos to do as Heinkel had requested, resulting in the rouge knight deciding to rejoin the knights and the auxiliary Astrea Manor being targeted by the Six Tongues once the power was detected.
• The following night, disguised assailants infiltrated the auxiliary Astrea Manor, suspecting Heinkel for treason against the nation by means of the Divine Protection of Mind-Changing. Initially taken aback by the false allegations levied against him by one of the assailants, he quickly realized that his son had been the culprit and ran to scold him for his actions. Though confused, Reinhard erased the Divine Protection he used, quelling the hostility of the assailants. As they left, Reinhard saw a man beyond a nearby window, mouthing to him, “If you care about your family, do your best to serve the kingdom."

• After Reinhard discussed it with the Six Tongues, the organization pulled strings to promote Heinkel to the Deputy Commander of the Royal Guard. Marcos personally notified Heinkel that the Council of Wise Men had decided to promote him to the role, much to his bewilderment and vexation.

They managed to resolve the issue and prevent a bigger conflict.
• About a month later, Reinhard van Astrea crosses swords with Vollachia's Blue Lightning, Cecilus Segmunt, in possession of two of the Ten Enchanted Swords. The Dragon Sword, unprecedented in history, recognized Cecilus as a worthy opponent and so Reinhard was able to fight Cecilus with the unsheathed Dragon blade. The duel resulted in a tie.

Trivia

• At a talk show held in April 6, 2025, it was stated by the author that the name Astrea was derived from the 5 Astraea asteroid.
• In Greek mythology, Astraea was a goddess representing the concepts of justice, innocence, purity, and precision. The author of the series likely garnered inspiration from Astraea when naming the House of Astrea, as the family exemplified many of the traits exhibited by the goddess. Reinhard in particular personified the traits of justice and purity almost perfectly.
• Ever since Reid Astrea, every member born into the family has had flame-red hair.
• There have been roughly 7 or 8 Sword Saints following after the first Sword Saint's death.
• Distinguished members of the family who earn achievements with the sword are given the honorary title of "van".
• Reinhard is stated to be the strongest Sword Saint to ever exist, even more powerful than Reid Astrea.
• Despite Reinhard being stronger than Reid, the first generation's Sword Saint is more skilled with a blade than the current generation's Sword Saint.
  • This is shown in how every sword with which Reinhard uses his family's sword technique shatters after use, except the indestructible Dragon Sword, whereas Reid could use even harmless items as deadly weapons.
• While not outright confirmed, it's heavily implied that Toska is a member of House Astrea and Reid Astrea's younger brother. Just like his supposed older brother, Toska had flaming red hair and was inhumanly strong, though not nearly as strong as Reid.
  • It has been confirmed that the first holder of the Divine Protection of the Sword Saint was the second Sword Saint, who was the son of Reid's younger brother.
