From MangaHelpers: Kamiya Hiroki always thought women had it easy. This thought was throttled by the fact that his 24-year-old sister does not work and plays games all day. Why couldn't he have it this easy? He wanted to become a woman and be lazy like his sister. After blogging about his rants about his sister online, a mysterious reader comments on his blog, stating that there are ways to swap bodies with others. This would bring Hiroki's dream of becoming a woman to reality . Unfortunately for Hiroki, swapping bodies had unintended consequences when he returned to his own body. [DrCoke]
