It seems that my previous synopsis was not very clear, so here is the clarification:An ordinary man dies and has the opportunity to be reincarnated, but after making a mistake in front of the goddess or basically desecrating her in his thoughts, he is punished by being reborn as a woman.But later, he discovers a method to temporarily recover his male body (legacy of lust).However, his endless desire will be the least of his problems.This world is nothing like the fantasy he dreamed.“As for genres, there's a little bit of everything: Harem, Romance, Comedy, Yandere, Yuri, MILFs, Lolis, Elves, woman-beast, Demons, Dragons, Gigantes, Priestesses, Androids, incest, Group Action, Futa, a little bit of SM, and much more. If it captures your interest, great!!!”.Here is the original synopsis>>>>>“Wait, you turned me into a woman just because I imagined that? I didn’t know you could read minds—that’s not fair!”(He had defiled her in his imagination in five different ways, each worse than the last.)After his death, a goddess granted him reincarnation in another world. But his uncontrollable lust angered her, and as punishment, she turned him into a woman.“Stop!... Don’t make that choice,” warned an old voice.Through an encounter beyond reason, he learns the truth: this world is nothing like the fantasy he imagined. It is brutal, merciless, and those who let their guard down don’t live long. He also discovers a method to temporarily regain his male form.Now, drawn into a battle for power where even the gods take sides, he fights not only for revenge, survival, and ambition, but also to protect those he holds dear—and everything he has built.
