Cloistered Nun: Runa's Confession

Young Runa/Luna entered a convent after losing her boyfriend to her sister Kumi. Her dream of a tranquil life at the convent is shattered when she is raped by the abbot and introduced to a life of torture and abuse. Leaving the convent she returns to her sister and former boyfriend to exact revenge by snaring them in a bogus financial scheme to promote Christianity in Japan and then departing with their money and a lesbian lover from the convent.
