the mature sister-in-law of lesbians, Sado's sister, Mazo's real sister, Ryoko Murakami, and Asahime HOJO.

At that time, Ryoko lost her parents in an unexpected accident. The Hojo family took Ryoko, who had no relatives like him, as his adopted daughter. His parents-in-law were very kind and his sister-in-law, Asahime, loved Ryoko like her real sister. A few years later, one day, Ryoko, who had grown up and started living alone, received a phone call. It was from a divorced maiden. The lady came to stay that night, and she was completely different from the atmosphere when she lived together, and suddenly touched the body of Ryoko with a thoughtful look.
