"Nyow, this might be a stupid choice, but I believe... Yes, it might just work. I'll use my Immortal King's Sacrement on you, so please.. Kill Ley and the gluttonous archbishops. I just want to Crusch remember..."

— Ferris, Arc 14, Ferris blessing Jens

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 in-order to gain information on how to cure Crusch. He is constantly thankful for Crusch and everything that she's done for him in her life.


Water Magic: Ferris is considered to be the best Water Magic user on the continent, earning him the alias of Blue. He is also the youngest to be given this alias. By directing mana to anyone whose Ola he's interfered with, he can make their body go out of control, enabling him to do things such as using their body like a puppet or destroying their circulatory system from inside. He can also die and heal himself to perfect condition.

  • Immortal King's Sacrament: Magic that can resurrect people from the dead. The effect of the magic depends on the skill of the user, Ferris was able to animate his mother's corpse, however her body didn't last long as the version of the magic he used was incomplete.

Divine Protections : Ferris has the Divine Protection of Water , which makes him highly skilled at Water Magic.

Equipment: Ferris owns a short sword he received from Crusch, but as he doesn't like to damage his skin, he generally refuses to wield it. He has wielded it once in an effort to intimidate an unimpressed Capella.
