Shinoda Ikumi

A full time housewife. The aunt of the protagonist (his mother's little sister), and is married to her husband Takeo for 5 years. Currently, she's living with her husband in a detached house near the protagonist's home.

A gentle woman with good manners and strong motherly instinct. During the childhood days of the protagonist, she changed his diapers everyday, slept with him on the same bed, and loved him as if he was her own child. As she likes children, she earnestly wishes to have her own baby, but because of her husband's busy work schedule, her desire is yet to be fulfilled.

Despite her plain and neat appearance, she's got eye catching proportions. Her G-cup breasts and hips capable of easy childbirth stands out even under her clothes. However, as her husband's not paying attention to her lately, she thinks that her womanly charm is lacking.
