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.
