Prologue: I Want To Go Home

In a certain world, there existed a chosen hero and the Demon King, the enemy of humanity.

The hero gathered his companions, while the Demon King invaded the human world.

After overcoming many hardships, the hero and his companions finally faced the Demon King in a final battle.

“Ughhhhhh!”

The Demon King, who had plunged the continent into terror, finally died, making a sound like a pig being slaughtered.

Yeah, killing him was good.

Now peace would finally come to the continent.

“Saintess, no matter what, wasn’t it a bit much for you to beat up the Demon King like that?”

The hero spoke to the saintess, who was holding a giant mace stained with the Demon King’s blood.

That’s right.

It wasn’t the hero who cut off the Demon King’s head, but the saintess wielding a mace.

The saintess mumbled something to herself, flashed a seductive smile, and then suddenly burst out laughing.

“It’s not my fault you didn’t land the finishing blow. After all, you’ve been swinging that holy sword and sweating blood for all that training, only for me to steal the glory, right? All you did was show mercy to the enemy every day, only to get stabbed in the back. You tried the same thing with the Demon King too, didn’t you? But guess what? I caught him? I did it? What are you going to do about it? What are you gonna dooo?”

Her bizarre laughter, as she shook her head from side to side, made it impossible to tell whether she was mocking him or if she had gone mad.

“Hey, what’s gotten into you all of a sudden?”

“Hahaha! Hero, you’re such a fool. Do you know why I especially beat up the Demon King? I was waiting for this exact moment.”

The saintess had been waiting for this day for a long time.

It had been 15 years since she came into this world, and she had lived for 15 years.

A crazy goddess had made her a saintess, asking her to support the hero and defeat the Demon King.

Her original position was supposed to be the hero’s bride, but there was no way she’d accept that.

She protested fiercely, and in exchange for decapitating the Demon King, they promised to open a portal that would send her back to Earth.

So she couldn’t wait around for the hero to try and rehabilitate the Demon King with his ridiculous persuasion efforts.

Having achieved her goal, the saintess finally threw off her mask.

“You… no way.”

“Goodbye, hero and your little gang. I’m off to return to my home! Now, Goddess, open the portal! 15 years! It’s been 15 years, you witch! Hurry! O! Pen! The! Portal! 15 years of eating oatmeal and hard bread is more than enough, don’t you think?!”

No matter what the hero said, it was nothing more than noise to the saintess at this point.
And then, a voice that had been watching over the saintess echoed in her ears.

-You’re being really harsh. Do you really want to leave me that badly?

“Are you freaking kidding me? I wasted my life because of you! Just open the portal already! You think being a goddess makes everything okay? Turn off this annoying saintess filter! I already dropped the act with the hero, so why do you still want me to speak politely to you?!”

After hurling curses at the goddess multiple times, a blue portal finally began to open in the air.

Whoooosh.

A portal appeared in the void.

“Woohoo! I’m finally going in. Let’s go!”

Having thrown off her mask and defeated the Demon King, the saintess was finally able to return home.

Up until this point, the foul-mouthed saintess was satisfied.

If there was a problem…

On the other side of the portal, monsters that she had only seen in the hero’s world appeared before her eyes.

“Wait, what the hell is this?”

Earth was being invaded by creatures straight out of a fantasy world.
