Mingze Lu

Little is known about his true origins; he claims to have lived for thousands of years and knowing Lu Mingfei for just as long. His current story begins in Herzog's research facility in Black Swan Bay, where he was found by Renata, a fellow orphan. Since Herzog kept him locked in "Room zero", he adopted "Zero" (Usually shortened to Z) as his name. He became friends with Renata and they attempted to escape the facility together, making an oath to stay by each other's side.
