Damian

About

One of three German Nazi scientists that discovers the ability to bring the dead back to life. As he and the other scientists grow old and express interest in living longer to profit from their findings, Aoi Nero grants their wish by turning them into remodelled corpses and transplanting their brains into young, suitable bodies. Unlike Gustav and Gulda, Damian doesn't rely on Nero to develop his powers. He acquires it on his own. Damian can use an ability called "ghost fog" ("gespenst nebel" in German), which is a black fog that causes its victim to lose their spirit and become Damian's slave when it hits them.
