Felix Argyle, commonly known as Ferris, is Crusch Karsten's knight.
Ferris has flax colored hair and yellow eyes. His casual wear consists of a blue collar with a ribbon, a blue dress, black tights, blue leggings, blue shoes, white arm covers, and a blue scarf tied around his right arm.
Ferris' cat like appendages are a result of his ancestors having Demi Human blood and because of this he was mistreated by his parents. The white and blue ribbons that he wears in his hair are a gift from Crusch and he always wears them no matter what he's wearing.
. He is absolutely loyal to Crusch and will do anything she says, however he will oppose her if needed. He also enjoys teasing other people.
Although he hides it through his actions and words, Ferris has a severe view on death and values due to his job as a healer, leading him to hold those who no longer have any will to live in contempt from the bottom of his heart.
Ferris can get emotional when it comes to Crusch, such as the time when she was infected by Capella's dragon blood, becoming visibly stressed by her poor condition and even going as far as to demand to see a captured Sirius so he could torture her to gain information on how to cure her. He is constantly thankful for Crusch and everything that she's done for him in her life.
Felix Argyle, commonly known as Ferris, is Crusch Karsten's knight. From the moment of Felix's birth, he had cat like features due to his ancestors having Demi Human blood, both his parents were humans so they both suspected the other of having an affair. As a result, his parents mistreated him and he was locked in the basement of the Argyle Mansion for the first nine years of his life where he was barely cared for. The basement was dark and his parents never spoke to him, when he was found by Crusch, she described him as "a fragile boy who was painfully thin, was black from being covered in dirt and filth, and couldn't talk properly". Crusch took him to the Karsten Mansion to be cared for and his parents lost their standing with the Karsten Family, leading to their decline. Felix was able to speak properly after being taken care of at the Karsten Mansion but because he had spent nine years without human contact, his speech was damaged, and he speaks in a cat like manner. To imitate Crusch and support her dressing like a man, Felix decided to dress like a female. He became friends with Fourier, who was the former fourth prince of Lugnica and Crusch's childhood friend, and to gain prestige as Crusch's knight Felix joined the Royal Guard on several recommendations, including Fourier's own, and he quickly became friends with both Reinhard and Julius.
Felix's father, Biehn, began associating himself with a slave trader and Crusch headed to the Argyle mansion on her own. Crusch was drugged by Felix's father in order to take back Ferris, and was handcuffed to a pole in Ferris' basement room. Felix demanded that his father release Crusch, Biehn however treated his outburst as a childish tantrum, and then explained that he wanted Felix to use the Immortal King's Sacrament to resurrect his wife. His father stabbed his mother to death because he thought she blamed him for everything that had happened. Felix still used the Immortal King's Sacramanet to reanimate his mother's body, which then proceeded to strangle his father to death, as a result of the magic being incomplete. Crusch was able to free herself. Felix's friend Fourier died of an unknown sickness afflicting the royal family, and later Crusch got the qualifications to be the next ruler, Felix was knighted by Crusch and they began their journey for the throne. Felix has a huge attachment to Crusch, she is such a massive part of his life that if she were to be taken away he would be utterly broken as a person, he does whatever it takes to protect Crusch, and will kill anyone that hurts her. He also has a strong attachment to life, and hates those who are weak.
