The warden who guards the witches

What is it like to be a prison boss in a different world?
Thieves, pirates, killers, scammers, terrorists...
Werewolves, vampires, witches, necromancers, succubi...
This is the Rose Iron Prison, where the most dangerous witches in the world gather.
"I must make this the best model prison in the world!"
A prison guard who traveled to a different world said.
"Warden, someone escaped again!"
"Catch him and put him in solitary confinement."
Today's Rose Iron Prison is also a peaceful day.
Warden: "I just manage my prison seriously, how did I become a big boss in another world?"
