There's a secret organisation is London that holds young girls captive, brainwashing them to believe they were being taught to be the perfect daughter. The young girls were taught proper language and posture, the little girls were always rewarded with sweets and toys up until their 16th birthday. When a girl turns 16, she is removed from the group. You were one of those girls, what happens when you are finally sold off? (Black Butler does not belong to me, but the girls and the organisation belong to me)
