江戸川 じゅん

Ubuse Shinobu's younger sister. That is, Chiharu's aunt. A cool-type beauty with wavy long hair. She works as an insurance sales representative.

Her husband has been out on a tuna fishing boat for offshore fishing for about half a year now, trying to repay a large, risky debt.

She's bursting with pent-up sexual energy from her ripe body, but she vents her daily desires by speeding around in her husband's car, an RX-8. She has a bit of a speed freak streak.

She belonged to the track team in her student days, so unlike her sister, she's athletically gifted. She also has a six-month-old infant.
