Gulda

About

One of three German Nazi scientists that discovers the ability to bring the dead back to life. As she and the other scientists grow old and express an 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. In her new body, Gulda can transform into a magical girl and control the gravity around her with a wand.
