Himeno was a Public Safety Devil Hunter, working under Makima's special squad. She was partnered with Aki Hayakawa. Himeno was shown to be very efficient and blunt in her duty as a Devil Hunter. She responded to a small and seemingly insignificant Devil by almost immediately using her Ghost Devil to subdue it. She was shown to have a more stern side and little tolerance for behavior from new recruits that would endanger or harm her subordinates.
