Ubuse Shinobu

A widow living in the neighborhood housing complex. A chaste woman with a touch of airheadedness. Her husband passed away about 15 years ago, but she never remarried, raising her daughter single-handedly.

However, as her daughter grew to the point of leaving home, she realized her own body had fully matured as a woman...

To shake off temptations of infidelity through sports, she joins a volleyball team... but perhaps due to her innate clumsiness, she's treated as “useless” within the team.

Her encounter with a young, attractive coach (the protagonist) will cause her ‘womanhood’ to blossom... or will it?
