Mayonaka no X Giten (真夜中のＸ儀典) is a manga series by Mikoto Yamaguchi with illustrations by Bareisho. It was serialized in Dengeki Maoh.
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.
