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.

Eshwar is the name of the author who transmigrated into his own novel after his death. Eshwar’s death was caused by his own magic which he had yet to control. Why? because I didn't think I would seriously die!!!!

Anyway.... my novel's protagonist is a selfish person. why you ask? because I wrote him and I wanted him to be like me. Muhahahaha, ha.

I reincarnated into my novel!

and that to as a villain who dies in the first half, will I stand still and die?

Of course not, I may have reincarnated as a villain but its not like I will live like he did.

I'll live my life as I want! and kill all the other villains.

Why? because I love the world I created, hahaha, ha.... (real reason: I love to fight.), who else will get the chance to look at the world they have created?

System I created is messed up for some reason and is doing everything on its own!!???

we'll see how it turns out with everything messed up, well(sigh...)

Oh, but because i have reincarnated as a villain, I got a new problem and that is,

I'm handsome (sparkles), I have to say, handsome people have their own problems.
