Hi guy im looking for this manga about a girl who lives in an orphanage and she gets tricked in to thinking shes going to become a star or something in the capital but instead shes sent to an all male prison were she is raped and beated by all the inmates. All this because a goverment program or some fucked up shit were they use young girls to please inmates in jail so they dont riot or something. Those are the only details I remeber

Anyone knows the name?
