Before Asura and Arachne were defeated by the Academy, they fused two pieces of their souls to a human one in a last-ditch effort to eradicate the DWMA. Unfortunately for them, their experiment did not go as planned when the human side of their child turned on them; rejecting the roles of a witch or a kishin. After their defeat, Lord Death discovered the half-breed, Alisha, under the care of Arachne's loyal cronie Mosquito, and has been keeping tabs on her ever since. Alisha soon developed the meister ability like her father had, and ends up enrolled into the DWMA. But when a new enemy appears that calls for Alisha to come to their side, what path will she choose?
