Mayumi Hayasaka

Mayumi Hayasaka was the adoptive mother of Ouka Hayasaka and Shusui Hayasaka. Mayumi was a seemingly very caring and loving woman as she devoted all of her spare time to caring for the Hayasaka twins, often playing games with them such as the wedding game which the twins used as a bonding mechanism even in their teenage years. She had a somewhat deranged side of her personality however as she kidnapped the twins from their real parents after she finished her affair with their real father, she never took the twins outside and even put several padlocks on the front door, this could have been out of revenge or more likely her desperation to have a family.
