Asaoka Haruko

She is Ren's caring older sister. At first glance, she appears to be an enchanting and beautiful woman with a mature and sexy personality, but she is just like her brother in the way she takes an interest in things.

She is an accomplished woman outside the house, but once she returns home, she transforms into a lazy older sister.

She was quite a delinquent when she was a student, and because of the trouble she caused, she is cooperating with her mother's remarriage.
