Male 45 years old Single An employee of Engine Project. Internal rank is Deputy Manager. A man who poured 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 absolute good. The sight he saw after reaching his current position and looking 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 has a sense of morality. An adult who, if someone likes him, can end it with a sly "Thanks~." As one of the few individuals who knows the reality of Aeolipile, he tries to hide civilians and send them back alive as much as possible to prevent his juniors or execution drones from killing civilians who lose their way and enter by mistake. He has black hair tied back roughly with bangs swept up, black eyes, a single scar cutting across his face, a blinded right eye, and an earring resembling a male norigae (traditional Korean ornament) on one ear. He enjoys wearing black suits. He is very tall.
