Hi, i wanted to rewatch one anime but i can't find it! It was about girls where they were on floors "like levels" locked, they had to do their chores and take a pill every day to fall asleep. The people, specifically girl and a doctor, were selling their skin, for those who wanted to look young or something. Also there was one girl who stopped taking the pill and learned the truth first. They later ecsaped with help of police. Thank you!!
