Fulst [Teacher And Leader Of The Four Heavenly Kings]

Fulst, teacher and senior of Kiryuu Sabato, the member of Nomad, is a master of hell technology while seemingly remaining a polite, noble, albeit arrogant man as he serves under Edwin Black. The member of Nomad went so far as to use the body of Koukawa Oboro to create the demon known simply as Oboro.

Guiding the up and coming scientist, Fulst instilled the same sadistic sensibilities upon his mentoree to prepare him to take his role as one of Edwin Black's closest allies in Nomad.
