Kasazaki Kodama

A woman in her early twenties born into a wealthy family.

She is married, not a virgin, and has no history of child birth. Although she is married, she has been unable to conceive a child. She and Ryouko visit Hinawari Onsen, her birthplace. The place is said to bless those with fertility benefits.

Although she is somewhat inferior to Yurie and Ryouko, she still has much larger breasts and a body more ample than the average woman.

She is quiet and a little shy, and when she is treated kindly, she is easily put at ease and is easily pampered.

Spoiler

She is in fact not infertile, but rather her husband is. Her husband and his family blame her for not being able to get pregnant.
