A lone wolf from another world who only trusts himself, Laevateinn calls none his leader and none his comrades. This is due to the personality of his Prime version, codenamed Zero, who is the first Killer Prince of his world. It also explains why he is a cynical nihilist who sees no value in tangible things and hates everything he deems pointless. His essence is from Laevateinn, the flaming sword that left the world in smoldering ruins. He hates being asked too many questions, and responds to any emotional provocation with either vicious rejection or defiance. This utter dread of being moved emotionally stems from a strong belief that it represents his own "weakness."
