One day, the majority of humanity had a collective thought.

‘I wish the world would just collapse.’

And then, that wish came true.

System: You are now a lowly male supporting role, a passerby who wants to go offline at any time, please keep secretly and grow vulgarly.

The original male and female protagonists, under his witness, became grudge couples.
The system feels that something is wrong.
Shi Yan instead persuaded him: Let the male and female protagonists come together in the end no matter what the circumstances are, isn’t it the self-cultivation of the tool man and the male partner?

- Description from novelbuddy

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.

Horizon Online. It was a death Virtual Reality MMORPG game where people had classes, hunted monsters, got riches, and fought similar players.

I, the strongest player in Horizon Online, managed to kill the last boss and expected to return to my home.

But after defeating the last boss, I was given a bonus stage, where I could choose one game of my choice. Without much thought, I chose an Eroge called ‘Sins Paradise’.

I arrived in Sins Paradise world as the minor villain with the same name as my character. But that didn't matter to me.

[Domination System! Dominate girls after completing the requirements!]

[Ding! You spanked Eliza Rose’s butt in public! Your Sins increased by 1!]

Making use of my overpowered strength and Domination System, plus my handsome features, I would conquer the best girls in the Sins Paradise.

My after journey to become the King of the world has begun!

*There will be no NTR.
