Lysis is a mysterious vampire who first makes an appearance in Arlee. Ever narcissistic, he tries to take care of his body and looks, and he despises being injured in battle, for it "ruins his beautiful body". He seeks a relationship with Velga Montor, Volga Montor's older twin sister, but she refuses him continuously. He is also despised by the rest of the female members in Fulein K. Lester's group, mostly the half-elven witch, Arche Klein, who refers to him as "a narcissistic pedophile with no hope of getting a girlfriend". As a retaliation, he tells her that she is not "a chaste girl", urging her to stay away from him.
Lysis later reveals an ability to duplicate himself. When trapping the heroes in an underground mausoleum, he promises that if they can find and defeat the real one, he will release them before all of the air escapes and they all die from lack of oxygen. Mint Adenade states that they should not trust a man like this, but having no other choice, Fulein decides that they should play him at his little game. Upon victory, much to everyone's surprise, Lysis keeps his word and releases the group, promising to meet them again another day.
Lysis has the ability to transform people into zombies upon slaying them, and he is also able to summon ghouls or other dark creatures using a devil summoning ring. As a result, he has trained himself to drain health from anyone he attacks. He also has the ability to confuse his opponents so that they will attack their allies or themselves for him.
