Peacekeeper

Saito Chinomi is a young Japanese woman who is copping from the trauma of her old job and the challenges she faced. Her friend Shasha decides that the best thing for Chinomi is to get a job. As it turns out, Chinomi isn't good at following directions and successfully gets hired as a prison guard at Nanba.
And now, she's running around being an idiot with the rest of the staff (and gossiping with Momoko.)
