The Asylum Lovers

Mienai is a 25-year old woman. In order to make some cash to support everyday life, she finds herself working among the crazies of the Cliff Side Asylum for the Mentally Ill and Disabled.
She thought this was nothing but useless. Until she came across a flattering patient. Who just so happens to be on the list of 'Most Dangerous.'
Number #1, Himitsi No Yami. Convicted and charged with 106 cases of murder, she is probably the most sadistic of them all. And the one that Mienai can't help but stick around.
