The prison is run by the female Warden by the name of Momoko Hyakushiki or Warden Hyakushiki. Although, she usually runs the male Nanba Prison.

She’s a stern, serious, subdue, and somewhat sadistic woman with an intimidating aura and a frightening glare who takes her job as warden seriously. She does have her kind side sometimes, but its usually towards her prison guards.
