- Description from Novelupdates

Alex is a normal girl in a post-apocalyptic world of monsters. The remaining pockets of humanity now coexist with tamed creatures that defend their towns from existential threats beyond the edge of the map.Then a Mark appears on Alex after a unique encounter. Now she can transform herself using monster essence! But the more she changes, the further from human she drifts.Join Alex as she becomes stronger, assembles her allies, and eventually founds a clan to fight for dominance of the region!It takes a monster to fight a monster, and someone has to breed them.Slightly interactive with periodic CYOA votes.This is an obvious parody with a semi-serious tone, lots of monster sex, a futanari protagonist, and a growing harem of monsters (mostly girls with a few exceptions).WARNING, Alex is bisexual and there will be both male and female monster species. If any of that isn’t your thing, move along.All characters are +18 including the monsters, who are sapient with the ability to consent. Some scenes have villains committing acts of sexual violence, but there will be no non-consensual sex scenes with the protagonist.

He was the final boss.The monster at the end of the world.The unbeatable nightmare humanity couldn’t kill.Then one day… he quit.Why?Because he saw two hunters having sex in his dungeon and realized Earth might have something way better than world domination.Now, disguised as a “totally normal guy” working at a sketchy restaurant, the most overpowered being in existence is on a personal mission:Sleep with every type of human woman.Catgirls? Yes. Elves? Hopefully. Tsundere sword babes? Absolutely.But hiding his god-level powers isn’t easy—especially when:His cooking accidentally gives people magic orgasmsAn E-rank hero gets famous for “defeating” him (total accident)Women keep throwing themselves at him... and monsters do tooAnd a suspicious ex-goddess shows up asking why he’s working night shifts at a ramen shopHe wanted pleasure.He got a restaurant job, a harem of disasters, and a world that keeps trying to make him a hero.This is not how conquering Earth was supposed to go..__________________________________No NTR, No Yuri
