Eris Boreas Greyrat

"As expected of Rudeus."

- -Eris

Eris Boreas Greyrat (エリス・ボレアス・グレイラット) is a noble girl and distant relative of Rudeus. She is a tsundere character with a short temper but has potential in the Sword-God style. During her journey to return home following the teleportation incident, she grows to love Rudeus.

Appearance
She has long red hair, a nice figure, and swords around her waist on both the left and right sides. At the end of the Decisive Battle Chapter, she has streaks of white in her hair due to mana strain.

Personality
She is violent, strong, tomboyish, and merciless towards anyone who holds negative emotions and or intentions against Rudeus. However, despite the outer aggressiveness, Eris also has a high level of shyness, often hitting Rudeus for touching her suddenly even tho she does the same to him. She and Rudeus have a mutual inferiority complex where both would assume the other is more wonderful than themselves, easily leading to misunderstandings.

Originally, she had a tendency to constantly release blood lust, but later controls it after years of training at the Holy Land of Swords. She is named the 'Mad Dog' due to her personality of bearing fangs at anyone for a period of time and is noted to be 'free'. She also has a high libido, often attacking Rudeus but it was later toned down after aging.

Background
Her full name is Eris Boreas Greyrat. Boreas Greyrat was one of the great noble families in Asura kingdom. Her behavior prior to meeting Rudeus was uncontrollable and violent. She was considered a failure as a noble. After the Teleportation incident, she was accompanied by Rudeus and Ruijerd on her way to Central Continent.

Back then, her biggest influences were Sauros Boreas Greyrat and Ghyslaine Dedorudia, and her family is known to have a beast race fetish.

Trivia

 * Eris is the goddess of War in the religion Rudeus has created. A wooden sword is currently taking the place as her symbol and is enshrined in the basement.
 * Eris name possibly comes from Greek mythology that is the Greek goddess of chaos, strife, and discord. Her name is the equivalent of Latin Discordia, which means "discord". Eris' Greek opposite is Harmonia, whose Latin counterpart is Concordia. Homer equated her with the war-goddess Enyo, whose Roman counterpart is Bellona. The dwarf planet Eris is named after the goddess, as is the religion Discordianism. Other names also come from Greek mythology like Anemoi, Boreas, Zephyrus.
 * When Eris left Rudeus after their first time together, she left her panties and stole a pair of Rudeus' underwear. The current whereabouts of her panties are not known.
 * In some previous loops where Rudeus didn't exist, Luke courts Eris and eventually the pair get married. In that timeline, Eris only has the potential of Sword Saint.
 * In previous loops where Rudeus didn't exist, Eris' nickname is Red Lion instead of Mad Dog/Mad Sword King.
 * Rudeus once referred to her as his Husband when he thought Zanoba might be confessing to him because in their relationship, Eris is the more sexually aggressive one and she made him feel like a maiden in love. While he gives arm pillows to his other wives, he would get one from Eris.
 * While Rudeus has a Harem consisting of his wives, Rudeus considers himself a part of Eris's Harem, which consists of himself along with Rinia and Pursena.
 * Like all who have descended from the Boreas Greyrat Household, Eris has inherited a love for Beast Girls. In addition, she also is fond of dogs and cats, possibly an extension to the inherited trait.
 * Even though she learned language, math, science, and etiquette in her childhood, she forgot all of them later on and can only read easier words.
 * Out of all of Rudeus's wives, Eris is the only one with large breasts. Because his other wives all had very small breasts, she and many others mistakenly assumed he only liked small breasts.
 * Eris dies at the age of 70. One day she collapses and passes away from old age.
