Michael is a hacker and the technical support expert in the STN-J. He is confined to the STN-J building 24/7 by the director Zaizen after being caught hacking into the STN-J's computer network (the only network he was unable to avoid detection in, as he states to Robin). Zaizen had given him the option of either working for STN-J or being killed on the spot, and Michael had opted for the former.

Michael somewhat avoids Robin at first, but then begins to warm up to her, particularly when Robin stays behind in the office at night to accompany him. Michael is able to dig up extensive information about various witches, police reports, and the like, all the while covering his tracks. In the end, he is finally given permission to leave STN-J headquarters.
