A Demon King Through The Worlds

In Infinity Castle.

Lucian was sitting with Daki on his lap, and Nakime playing the biwa to entertain him.

From time to time Daki would put a grape in his mouth.

'This kind of life is so good' Lucian thought happily, as he savored the sweet grapes, the softness of the beautiful woman in his arms and the melodious playing of the biwa.

Looking at the slightly blushing Daki, who was snuggling in her arms, as docile as a kitten, Lucian felt like kissing her.

"You're so cute~" he said, lightly kissing your pink lips.

"Who is she?" Suddenly Mitsuri approached asking, her a little sour.

She couldn't help but feel a little jealous seeing them so close.

'No, of course I'm not jealous, I don't even like him... even though I accepted his proposal.'

"This is Daki, my wife and your co-wife." Lucian smiled, introducing Daki in a simplistic way.

"Co-wife? How many are there?" Hearing this answer, Mitsuri soon came to another important question, attracting Daki's attention as well.

"You, Daki and Kie, there are three of you for now, in fact I should get you together so you can get to know each other" Lucian said with a smile.

"Kie, come to the infinity castle" He called telepathically, at the same time opening a door for her to enter.

Soon, three beautiful women gathered at the table.

Kie with her black hair, and gentle features that gave off a motherly glow, and beautiful dark purple eyes.

Daki with his silver hair that slowly turns lime green, lime green eyes, pale skin, his sharp features containing pride.

And finally, Mitsuri, with her long pink hair that turns green, her light green eyes that shine with passion and youthfulness and a great pair of... attributes.

All with different characteristics, but all beautiful, and looking at them, Lucian felt a certain feeling of accomplishment welling up in his heart.

"This is Kie Kamado. Kie, these are Daki and Mitsuri Kanroji, I hope they can all get along well in the future" Lucian introduced them.

"It's a pleasure to meet you." Kie, the more mentally mature one, took the initiative to greet.

"Likewise" Daki said then, she and Kie knew it would be a polygamy relationship for a considerable time, and she was completely fine with it.

"... Yes, it's a pleasure to meet you" said Mitsuri, even though she had been surprised, her personality prevented her from saying anything unpleasant.

"Kie, Daki, retreat first. I will talk to Mitsuri" asked Lucian, after all he would have to resolve the conflicts that Mitsuri might have.

Hearing this, they left the room together while talking.

If he wanted to use force, no one could stop him, but that is precisely why he would not use force at any time.

Something forced wouldn't make sense, it wouldn't bring pleasure, and even if it's said to be for the feeling of achievement, forcing it wouldn't bring it either.

"How have you been?" He asked the hesitant Mitsuri.

"I've been fine" She replied somewhat unnaturally, a forced smile on her face.

"You've been feeling bad about betraying the Demon Slayer Corps, haven't you?" Lucian said, letting out a sigh.

He could understand her. Switching sides raises many moral and ethical questions.

"...Yes." After hesitating, Mitsuri confirmed Lucian's guess.

Turn her sword against those she fought for, those who were her allies, those she protected and begin to fight for the enemy, those she and her companions had sworn to kill.

 It made her feel guilt, a guilt that weighed on her heart and gnawed at her mind.

"Don't blame yourself too much, people change their minds all the time and you don't need to fight your former allies, I won't force you to."

"Looking at it differently, I forced you to cheat on them, so don't feel guilty, and just think about how you want the wedding ceremony to go." As she approached, Lucian tried to dissolve this guilt she carried.

"But…" Mitsuri wanted to say something, the entanglement still visible on her face, but Lucian interrupted her.

"This is not a request, it is an order, and as someone who has been captured you have no choice but to obey." He said, his tone authoritative, giving her no options.

"Right!" Understanding Lucian's intentions, Mitsuri put aside those worries, and nodded, returning to her cheerful tone.

Then looking at how close Lucian was, she raised her head and closed her eyes.

'does she want a kiss?'

And of course, Lucian didn't refuse, he lowered his head and kissed her, enjoying her delicious lips.

Wrapping her in his arms, he lightly stroked her back.

"I really don't understand these fools" After finally breaking the kiss, Lucian began to speak.

"What are you talking about?" Mitsuri tilted her head, confused.

"Of those who rejected you, your hair is so shiny and soft, your face is so tender and beautiful, and your voluptuous body is so attractive." Lucian praised her fervently, his ardent gaze roaming over her.

"Do you really think so?" Mitsuri asked, her face flushed and her gaze shyly looked away.

"Of course, by the way, you should get some new clothes, you know bigger clothes, this one is showing too much." Lucian then pointed to the opening that showed part of Mitsuri's breasts.

"Don't get me wrong, I didn't want to show it off." She nervously explained herself, lest he consider her an exhibitionist.

"I know that, in fact I kind of like this look, but I don't want anyone else to see it." Lucian said, lightly touching her face.

"I understand" Mitsuri replied, before burying her face in his chest, a feeling of joy rising in her heart as she felt the concern and possessiveness he had towards her.

After being rejected for a long time, she wanted to feel desired, and he was wanting her intensely.

"And there's another thing, I don't know if you know the demon hunter mark, but if you train with Kokushibo, you can awaken it."

"What is the hunter's mark?" Mitsuri asked confused.

"It is a mark that when awakened grants a great increase in physical capabilities, despite shortening the life of those who awaken it, making them unable to live beyond 25."

"Actually, I think it's more appropriate to call it a demonic mark, after all, at the moment only demons have it, and only they are capable of staying alive." Lucian explained.

"I understood! It looks cool, I will train with him to awaken the demonic mark!" Mitsuri said excitedly, thinking about the idea of increasing her strength.

As for whether it's demon hunter's mark or demonic mark...

If her husband says it's a demonic mark, then it is.
