Voice
Since the students of FIEND’s school for gifted troublemakers (Not the official name of course) are often unable to attend public schools as well, the academy employs a few FIEND agents as it’s “Mundane Instructors” to teach a few standard courses such as history, math, science, and english. Voice is the academy’s English teacher, a mysterious woman with a sort of “super-ventriloquism”, able to throw her voice to any location in the world. She also has an impressive knowledge of espionage tactics and martial arts, leading many to believe she was some sort of spy or secret agent before joining FIEND, much like Ultimatum who she seems to have a budding romance with.
