A Demon King Through The Worlds

Even if Lucian didn't like this incompetent subordinate very much, he wouldn't let them kill him.

Only he can kill his subordinates.

"He died? It takes at least the power of a hashira to kill the Hantengu." Commented Daki upon hearing the news.

Even though she felt no sadness for her fallen comrade, she was forced to recognize his strength.

"Yes, let's end communication, I will pursue while there is still time." Lucian said before running to the Kamado house, arriving in a few seconds.

"Kie came up with something, I'll be gone for a while." He quickly notified them, before entering the infinite castle through a sliding door.

"... All right?" Kie nodded, dumbfounded as she watched the door that suddenly appeared just disappear.

"It disappeared?" Tanjiro asked, equally astonished by what happened.

After all, it's not often that you see a person simply disappear into thin air along with a door.

'Are demons really that magical?' This thought crossed the minds of everyone present.

"Nakime send me to ****" Lucian asked as soon as he appeared in the infinite castle.

"Yes" Nakime replied, as silent as always, touched her biwa and opened a spatial door, which Lucian entered.

Arriving at the spot where Hantengu had died, he took a look at the remains of the fighting, and closed his eyes, searching for Hantengu's last memories.

Pink hair with green tips, green eyes with a spot below each one, a sword similar to a whip, a fighting style that looks like dancing, in addition to its great attributes...

Seeing these characteristics Lucian soon recognized the demon slayer - Mitsuri Kanroji.

As the memories passed, it wasn't long before he learned how Hantengu died.

He was forced into the sunlight.

And it couldn't have been any other way, after all, in the original work Mitsuri needed help and the hunter's mark.

'But still… It can't be a coincidence that this battle happened.'

It would be almost impossible for this meeting to simply happen, especially when Hantengu was in hiding.

The birth of Yoriichi, an individual who possessed the hunter's mark, transparent world and altruistic state since birth, showed that there is some type of entity that is against demons.

Whether this existence is a god, a conglomerate of the world's consciousness or any other similar thing.

In addition, many worlds demonstrate a "destiny".

'Such facts make me think...'

Returning to focus, Lucian inhaled the odors in the room, quickly separating Mitsuri's scent.

Once he had a direction, he began to pursue. And soon he would find her.

After the fight Mitsuri would certainly be somewhat weakened due to injuries and fatigue, coupled with the fact that demons don't usually receive reinforcements, she isn't moving very fast.

As for the helpers... Which one would survive a higher moon?

"Ack!" Mitsuri groaned painfully as she hit her back against a tree after being hit by Lucian.

"You… who are you?!" Vigilantly she asked.

"I am Lucian, the demon king" Lucian smiled, as he bowed slightly at his introduction.

Looking at his polite and friendly posture no one could tell that he had just attacked her.

"Demon King?!?"

Even though Mitsuri was terribly surprised by this self-introduction, she didn't doubt it much.

Even more so when remembering the speed that she was unable to perceive, much less react, and the force that almost tore apart all of her internal organs in a single blow.

"Cough! Why aren't you done with this yet?" After coughing up some blood, Mitsuri asked, memories of her life gradually flashing through her slightly blurred eyes.

'It's a shame I wasn't able to find a husband…'

"I need a replacement for the one you killed" Lucian said, as he approached her.

Then he squatted down and grabbed her chin.

"I heard you joined the Demon Slayer Corps for a goal, how about I help you complete it?"

"...help me complete my objective?" Mitsuri repeated, her eyes clearing a little to observe Lucian's face.

"No, I won't let you turn me into one of the evil demons!" She repudiated, pushing away the temptation.

"Evil ones? Humans kill much more than demons, whether other humans or animals, and they have even extinguished entire species."

"If a demon kills for food, a human kills out of greed and envy. As I recall, humans started countless wars, and demons none."

"Life is not about good or evil, and even if it were, when you really evaluate it, those who are evil are the humans."

"…" Although he wanted to refute, Mitsuri was unable to. She couldn't see any flaws in Lucian's logic.

Did humans kill each other? Yes. Did they extinct species? Yes. Have they started countless wars? Yes.

So why can they say that demons are evil even though they have already caused an equal or greater amount of harm?

"...But being forced to devour humans and fear the sun..." Mitsuri said, still refusing to become a demon, keeping the last insistence in her heart.

"You will not be forced to devour humans. And you still haven't noticed? It's daytime right now, and I'm in the sunlight." Lucian continued to tempt her.

Even if she refused to eat humans now, after the transformation that would change a lot.

This questioning and persuasion is just his kindness.

If she accepted, the process would be much easier and faster.

If she refused, he would just use a little more force.

"By becoming a demon you will remain young and beautiful forever, with an immortal body that never tires and you will obtain supernatural powers."

"Besides, I want you to become one of my wives, meaning you will be a queen." Lucian was slowly seducing her.

And after great effort, he got what she wanted.

"I accept!" Mitsuri's already weak resolve finally collapsed.

She never had grand and noble desires for revenge and justice.

She has never had one of her relatives killed by demons.

She had joined the Demon Slayer Corps because she wanted a husband stronger than her, or rather a husband who was capable of accepting and loving her the way she is.

And she believed that only someone stronger than her would be able to accept her enormous strength and great appetite.

Now that an opportunity knocked on her door, with a handsome man asking her to marry him, she decided to accept.

'...Not that I have any other choice...'
