[Unique Characteristic: You acquire ‘Protective Instinct’ (保護本能).]

“The masterminds are cooler than heroes,” I mutter as I stare at the chess pieces before me. It is easier to be the one who sits in the shadows and moves the pieces, likewise deciding the flow of the game.Heroes will foolishly sacrifice their lives for the good cause and villains will sacrifice the world for their own gain, but masterminds will use both the heroes and villains to their own benefit.Why, you ask? Well, that's because I've lost my life once while trying to be a hero so, I don't want that anymore. I'd rather be a mastermind who molds the world as per my convenience and live peacefully. Because, why not?***[Defender of Divine Glory says you are the hope of this world.]What?[Goddess of Wisdom believes that you will be the one to save the world.]Wait, what?![Propose the Grand Duke the idea of a fake marriage.]And, why would I do that?![Stop the assassination of Prince Eric.]Why would I save him?![The candidates for the throne are:... Who will you choose?]Ah! I give up...It seems like a curse that anyone who wishes for a slacker life in Isekai will have to go through the most troublesome things.In my past life, I died because of one rookie mistake but after being transmigrated in the world of fantasy I've gotten an opportunity to start afresh, but unlike the protagonists who look for their love and glory, I'd rather make money and live a life of a slacker.I have magic, I have power and I have money, what else do I need?Well, that was the plan but this damn system is getting on my nerves. I mean who in their sane mind would want to mess with the complicated royal family and political affairs? But that's not all though.I've also become the saviour of this world. Things just can't be anymore worse!Besides, the penalty of failing this quest is...[Failure: Destruction of the World.]It seems like if I screw up in selecting the right person then the destruction that is going to befall the world won't be stopped.If I speak of my reward then it's this vague thing.[Reward: Fulfillment of any wish.]“If that's the case then, I'd rather choose the person who would be the best fit for the throne.”And that's how I decided that I would become the Kingmaker.

“You might be my wife, but I shall not lay a hand on you.”

“Is that so? Then can I lay my hand on you?”

“……Pardon?”

***

Around 20 years in the future, the world is destroyed due to the invasion of demons. There’s only one way to prevent the destruction.

Marry the Duke known as the Monster and give birth to his child who will grow up to be the future warrior.

“Mielle, that marriage, I’ll do it instead.”

Yelena, who saw the future,
decided to get married to the Monster Duke and give birth to his child to save the world, however…

“Are we going to keep being idle like this?”

She thought she would be able to get it over and done with (?),
but her husband’s impregnable fortress-like defenses are beyond imagination!

“I told you to strip! Why aren’t you stripping?! Is it a part of your skin?”

Can Yelena safely give birth to the warrior and save the world in the end?
