Eris Greyrat (formerly Eris Boreas Greyrat), is a distant older cousin and now, wife of Rudeus Greyrat. She was of the Boreas Greyrat noble family who Rudeus met when he was hired, despite his age, to become her academics teacher.
She is violent, strong, tomboy 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 has 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 later toned down with age.
Eris became an apprentice to Sword king Ghyslaine Dedorudia (who was also learning under Rudeus' academic teachings) in her childhood, and was later taken by Sword god Gal Farion as his own disciple.
