Black Mask

The mysterious man leading the Ironblood Chain Brigade. He wears a black iron mask and is dressed entirely in black, including a cloak. He is able to directly withstand Inglis's punches when she activates her Ether Shell. He is one of the few characters in the story, aside from Inglis, who can manipulate ether. Because of this, Inglis speculates that the Black Masked Man might also be a Divine Knight, but the truth remains unknown for now.
