Born in the year 405 of the Armored Dragon Calendar.
Heiress of the prestigious noble Boreas Greyrat family in the Asura Kingdom.
Two years older than Rudeus and his paternal cousin (their fathers are cousins).
Raised with a violent nature due to the influence of her grandfather Sauros.
Though rough, she generally refrains from initiating physical contact with important people. For example, she would hit Rudeus if he suddenly touches her buttocks or chest, but she won’t physically engage with other women even if they flirt with him.
Appearance
Distinguished by her vivid crimson hair.
Her body is voluptuous. When Rudeus used healing magic on Eris, who was suffering from seasickness while they were on their way to the southern port town of Wenport on a ship, he struggled to control his sexual urges towards her exposed figure.
After Eris became the Sword King and during the battle of Rudeus and Orsted, she met Rudeus again after a five-year separation. Rudeus noted that she had become slim but very muscular.
Despite being told that it’s impossible for her to live as a noble lady, and that her father Philip wouldn’t be suited for it either, Eris was taught swordsmanship by Ghyslaine to become an adventurer.
Initially, she wasn’t particularly motivated to become strong and didn’t seriously study swordsmanship. However, since swordsmanship is the one skill she can use to win against Rudeus, she became more dedicated.
She has respect and affection for Rudeus, who doesn’t abandon her despite her selfishness, and she strives to become a woman who matches him.
Her talent as a swordsman surpasses Paul’s, and Ghyslaine and Ruijerd even believe she could surpass them. However, due to her personality, she can’t use the Water God’s techniques.
During the time when Rudeus was her tutor, he taught her beginner-level fire, water, and wind magic, which she learned and mastered. However, she didn’t receive combat training with magic, so she can’t effectively use it in battle.
After the teleportation incident, she learned the Demon God language while traveling through the Demon Continent.
Being a member of the Boreas family with a strong sense of ownership, she loves beastmen and creatures with soft fur, but her intense hugging scares them.
Later, she learns to gently pet animals under the advice of Lilia.
In the timeline of Old Rudeus, she couldn’t reconcile with him and was an enemy. Despite that, she secretly helped him. She sacrificed herself to protect Rudeus during the fight with Atofe.
According to the story of the Dragon GodOrsted, in a timeline where Rudeus doesn’t exist, she remains an advanced swordsman rather than becoming the Sword King. She joins the Asura Knight Order, and Luke falls in love with her and proposes. She ultimately rejects his proposal and marries him.
During Ariel’s coronation, she had the role of bringing her grandfather Sauros and father Philip to support the Second Princess faction.
