Maxim Feller is a character from the anime E's Otherwise. He is an esper who works for Eiji Sagimiya at the organization known as ASHURUM. His primary role within the story is to appear as a replacement for Kai, seemingly as part of experimental procedures conducted by the organization. Maxim is described as having a striking, smolderingly sensual appearance, with a chiseled visage that is said to symbolize his power and an air of mystery. His physical traits include purple hair and purple eyes, and he is depicted as an adolescent male. As an esper, Maxim possesses incredible psychic abilities, which he derives from the experiments performed on him by ASHURUM. His motivations are tied to his allegiance to Eiji and the organization, though his personal goals and internal conflicts are not elaborated upon in the available information. His key relationships center on his connection to Eiji, who directs his actions, and his role as a replacement for Kai suggests a competitive or oppositional dynamic with the protagonist. Maxim does not undergo significant character development within the span of the series, serving instead as a powerful operative deployed to advance ASHURUM's objectives. His notable abilities are his esper powers, which mark him as a formidable force among the psychics in the world of E's Otherwise.
