BREW exists on a lost island north of Alaska where there used to be a witch’s tool development facility before it got destroyed from an accident. That accident resulted in a special magic magnetic field in the center of the island - BREW is inside of there - and staying in that magnetic field for longer than 20 minutes will result in a person’s body getting destroyed. A small army of Shibusen students and staff are already headed towards the island, and the plan is to have Sid’s force take care of the Arachnophobia forces while Marie, Stein, and the students head for the magnetic field. Once there, Marie and Stein will head into the field while the students stand by outside until the two return. Things start out according to plan, however Sid’s force is soon ambushed, and Sid finds himself facing off against Mifune. (thetvdb.com)
