An elite salaryman (aspiring NEET), gets reincarnated and genderswapped into a princess living an idle life of masturbation...!? Kishibe is an elite office worker who dreams of becoming a NEET who has attained FIRE (Financial Independence, Retire Early). The fulfillment of his dream is now right before his very eyes!! ...or was, when he died saving a girl from getting hit by a car. A self-proclaimed god felt pity for such a man, so she reincarnated Kishibe into another world where he could live as a NEET. The next thing he knew, he had become Iris, the princess of a superpower kingdom!! Blessed with incredible beauty and not having the need to work even once, Kishibe won the jackpot with a life full of indolence, freedom and masturbation!! ...is what he believed, but there was a catch. Princess Iris seemed like she possessed a trait that made others love her at the highest level (a skill?), and various girls just keep coming on to her (who was formerly a man)...!? This is another world where one can experience endless love and eat meals that one didn't work for (does it taste good?), it's an envy-inducing, genderswap isekai story with a super NEET harem!
