Enoch

Enoch (イーノック, Īnokku) was formerly a Rune Knight, who, while he had great proficiency in close combat, was incapable of using Magic, and was later experimented on by Eva Kiesler for the next 3 years, turning him into an undead being, removing all of his human limits, but still not granting him any way of using Magic. He later escaped, which was taken as an act of betrayal by the Magic Council, labelling him a criminal.

Trivia
