A Witch named Kazuya Misawa is on a high-profile trial for murdering his business partner. However, in spite of police tampered evidence, since Misawa was never seen touching the man it's not likely he'll ever be convicted. The STN-J now has to take care of Misawa themselves, before he kills again.
