Reijou Monogatari

Three sisters of the Saijō family - Michie, Saki, and Erika - lived together peacefully in a quiet house. Their parents have died but left them a very large fortune, which evoked jealousy in people surrounding them. On Michie's twentieth birthday their greedy and corrupt uncle, who recently lost a vast amount of money due to failed business transactions, sent his goons to extort from the young women the fortune they rightfully possessed.
