Sexy Tanaka-san

The manga centers on two women: Kyouko, a regular accounting department office worker who is around 40 and who maintains another life as the belly dancer Sali, and Akari, a likeable 23-year-old temp worker and colleague of Kyouko who is seeking marriage. Akari is convinced that her youth and cuteness are her only merits, so she is seeking to find a partner by going to mixer after mixer, perceiving her time as "running out" while feeling empty and lonely. A certain incident leads her to finding out about Kyouko's double life as a belly dancer, and she slowly begins admiring Kyouko. (Source: Anime News Network)
