貞操逆転世界

Momona Ichikawa, a high school girl, wakes in a hospital bed and finds herself in a Japan where the sexual double standard has been flipped. Her classmates trade dirty jokes in the open, the red-light district is stocked with shops for female customers, beer billboards sell themselves on men in high-cut swimsuits, and late-night TV books topless comediennes. Momona is the only person who finds any of it strange, and she still has to get through ordinary school days.
