A group of correctional officers is going above and beyond the call of duty by forming a dance group in an effort to shake off the image associated with their chosen profession.

M-girls, which boasts five female members from the Mine Rehabilitation Program Center in Yamaguchi Prefecture, is the brainchild of the correctional facility's first female administrative manager, Hiromi Kobayashi.

When they take to the stage, the women trade in their prison blues for racier outfits in a bid to change the public's grim perception of prison guards. They also hope to lure more female recruits to offset the high job turnover at the first-ever penal institution of its kind in the country.
