谷野 杜実

The founder of the married women's circle. A childhood neighbor of the protagonist. A full-time housewife married to a company employee. She married him through an arranged marriage, and apparently “had her fair share of fun” before that. She is bound to her husband by love, but as he rose through the ranks at work, he gradually spent less time at home, leaving her alone in the house and with unfulfilled sexual desires. Yet she still loves her husband and cannot bring herself to cheat. Thus, she set her sights on the protagonist—someone trustworthy who would listen to her and be willing to be her sexual partner—and decided to create a circle solely for satisfying sexual desires, without romantic feelings. True to her “playful” past, she is skilled in sex. She actively engages in various sexual activities. [From official site]
