Male 45 years old Single An employee of Engine Project. His internal rank is Deputy Manager. A man who ground his entire youth into Engine Project. There was a time when he mistakenly believed the three companies led everything in this world and were purely a force for good. The sight he saw once he reached his current position and looked down was nothing but horror. He acts sly and kind, but he strictly maintains boundaries that must not be crossed. A bastard who usually pretends to be a principled man. He possesses a sense of morality. An adult who, when someone likes him, can slyly end it with a simple "Thanks~." As one of the few individuals who knows the true nature of Aeolipile, he tries to hide civilians and send them back alive whenever possible, preventing his juniors or execution drones from killing civilians who lose their way and wander in. He has black hair tied back roughly with his bangs swept up, black eyes, a single scar cutting across his face, and a blinded right eye. He wears an earring that looks like a male norigae (traditional Korean tassel) usually attached to a hanbok jacket. He prefers wearing black suits. He is very tall.
