The World Tamer Harem System: The Omniverse Will Be My Harem

Chapter 5: Chapter 4: The Kamado House



Soon Yiggrit and Tanjiro found themselves at the doorstep of his house.

(It seems everything is just as planned so far, good) The blue-haired young man looked around and found himself smiling as it was all just the way he left it for his plan.

"Welcome Yiggrit, this is my house. Nezuko, Mom, Hanako, Shigeru, Takeo, and Rokuta must all be inside. Please come in, I couldn't ask you to go back alone after you got all the way just for me." Tanjiro invited his new friend to come in with a bright smile.

(I didn't come just for you, I came for your mother and your sisters… I'm still a man of principle at heart, even if my principles are evil and perverted. So, I can't have my brothers-in-law die to a loser villain like Muzan.) Yiggrit shook his head internally at the idea of letting Muzan win.

"Don't mind if I do." Yiggrit followed him inside.

It was a simple house very similar to the one he has in the village with sliding doors and a Japanese style.

"I'm home! And I brought Yiggrit with me!" Tanjiro warned as they got inside.

Once inside, they had to take off their shoes, and then they went further inside until they reached the living room, where there was Kie with the youngest brother, Rokuta sleeping in her arms, while Shigeru and Takeo were fighting.

Hanako was trying to get the boys to stop, while Nezuko was cleaning around the place.

"Welcome back, Tanjiro. You came back early, how unusual of you. Oh, and welcome to our home, Yiggrit." Kie greeted them both as they came in with a soft smile on her face.

She was a woman with a noticeably light complexion, kind, dark purple eyes that appeared a lighter color around the rims of their irises, and a small beauty mark located on the left of her face below her lower lip. She had black hair, worn tied back in a messy bun with a few loose strands left to dangle over her face.

She wore a purple and cream checkered kimono with a white and long-sleeved kappōgi over the top, she also sported a white tenugui cloth that she wears around her head, covering most of her hair.

(A housewife in her natural environment, her amethyst eyes carry the weight of the kindness that forgave me so easily, and her layered outfit is a testament to her reserved but intricate life as a mother.

(I long since appreciate her looks, and what little I know, but I can only hope to learn more in my pursuit to make her, mine. Such is my perverted way, my path of lust and love.) Yiggrit looked at her as his thoughts went off, after all, there was no helping his nature, at least he seemed to believe so.

In her arms, Rokuta has light skin and dark red eyes along with white pupils. He wears his black hair in a bowl cut and wears a blue kimono with white diamond patterns, checkered pants, and white socks.

At the same time on the side, rolling on the ground as they struggled against each other. Shigeru and Takeo continued their little fight.

"It's my turn to play with the wood sword!" Shigeru complained as he pushed his bother in their squabble.

He was a young boy with a light complexion and dark red eyes with white pupils, just like the rest of his family. His black hair was worn as a buzz cut.

Shigeru wore a light green and black patterned kimono with a light green haori over it and a white nagajuban under everything.

In turn, he got pushback from his brother, who on his own had no intention of losing out on this matter.

"As if! You kept it forever last time! So I get to continue my turn as well!" Takeo replied with evident frustration at this situation.

Takeo had short, spiky black hair similar to his older brother Tanjiro, and he also had a light pale complexion that contrasted with his dark red eyes, which also had white pupils. He was significantly similar in appearance to Tanjiro, except he had a beauty mark beneath his right eye, just like his mother, and lacked the scar on the top of his forehead.

Takeo wore a cloud-gray iromuji kimono with a sea-green haori on top of it, along with a pair of tobi pants and boots. He also sported a turquoise and black patterned scarf.

The rebuttal immediately came, as the siblings continued to roll over with each other as if they were wrestling.

"It's not my fault you let me do it! It's still my turn now, so give me!" Shigeru retorted unphased by his brother's words.

That was however not the end.

"That's not fair! I only let you cause you asked me! Stop being mean!" Takeo was further irritated by this response.

While from the side, their sister attempted the stop this quarrel.

"Stop it! You two! Tanjiro will be mad if he finds you fighting like that, he said we should get along." Hanako tried her best to pull them apart, but unfortunately, her efforts weren't rewarded, as they kept going at it.

She was a young girl with black, shoulder-length hair and fringe above her eyebrows. She had large, dark red eyes with white pupils and pale skin, much like the rest of her family.

Hanako wore a peach Iromuji kimono with a pale pink haori worn over it. She also wore a dark peach obi with a pink obijime and a beige-colored obiage. Under all of this, she wore a white juban.

(AN: Images Here)

"She's right, you two keep fighting for no reason. Mom won't be happy once she's done putting Rokuta to sleep." The eldest sister of the house added before going back to focusing on her task at hand.

Though she was busy cleaning, her attention was quickly brought to the two, who just arrived.

She had fully black hair, was tied back in three low buns, was decorated by pink ribbons, and had eyes of a darker pink color. She wore a layered pink kimono with the white yuban underneath, along with a white Onbuhimo cloth tied around her, which she used to carry her little brother, Rokuta Kamado, on her back.

(AN: Images Here)

"Hey! Enough of that you two!" Tanjiro immediately went in and separated his younger brothers.

"It was his fault! It's my turn and he won't let me play!" Shigeru was quick to say as he pointed at his brother.

"No, it wasn't! He played for way longer, his last turn! So it's still my turn!" Takeo added with a frown.

"Now, now, guys, you can't argue over this so much, let's talk it out, and see what we can do," Tanjiro responded and took the two of them with him.

This brought a smile to Kie, who turned to Yiggrit who was standing there witnessing it all happen.

"Come here, and sit, please. It's a pleasure to have you in our home. I bet you're why Tanjiro made it so early, he tends to get a little too sidetracked helping others." Her voice was soft and caring as she smiled at him, urging him to sit next to her.

"Thank you, Miss Kamado." Yiggrit happily took his spot sitting next to her with an almost dastardly smile.

"Hanako, go get the tea and some snacks for our guest," Kie ordered as she continued to hold the sleeping Rokuta.

"Me?!" Hanako's eyes widened as she was startled into a blush.

"Yes, you. Your brother is taking care of those two little troublemakers, and your sister still has work to finish. Plus, you need to know how to do this as well, it's part of growing into a proper lady." Kie nodded her head as she responded softly.

"Y-Yes! Mom!" Hanako went off a bit bumbling, not used to being handed such tasks.

"Look at how you kids grow, it's both a marvel and a tragedy to watch… Oh, don't mind this old lady's rambling, a child like you probably won't want to listen about such things." Kie smiled though her eyes were sober as she spoke, before looking at the blue-haired young man almost apologetically.

"I don't mind, I like to listen. That's how you learn, and I'm sure a wise beauty has a lot to teach a youngling like me." Yiggrit replied with a smile.

"Wise, you say? Am I being called old? Ah, how cold, here I thought you were redeeming yourself into a gentleman." Kie teases playfully to ease him and let him feel more at home.

"No, I mean my words, especially the beauty part." Yiggrit chuckled unbothered by her teasing.

"Though I confess, it's been a while since anyone called me pretty, much less beauty, and it's nice to hear, even if you're just being nice," Kie confessed casually indulging a bit in the conversion, even if ironically.

"It's a wonder how so many beautiful women have a hard time believing they are. I guess not even age can beat a conflict of the mind on its own." Yiggrit sighed sounding a bit offended she disbelieved his words.

An eyebrow rose on her face, and she giggled before saying. "Look at you, I didn't know our new little neighbor was such a thinker. Though, I think you should focus on enjoying yourself and leave that to the grow-ups. You do a lot for people already."

There was genuine surprise in her voice, as she didn't expect him to speak like that at all. Though she thought he was pretty impressive for all the work he did for the village in a single week, a kid was still a kid, or at least that's what she expected.

"You make it sound like I have to sacrifice my enjoyment to do those things, I know it might sound weird, but I do a lot of that for fun," Yiggrit said sincerely.

"… A-Apologies then, I'm happy this is what brings you joy then, may it never change." Kie was almost too shocked to answer.

After all, was he being honest or just doing his best to sound good and fully clean his perverted image? She wasn't sure.

"That and great company like this makes it all more than worth it. If I'm going to carry it all on my shoulder I'm happy to know I can at least come to miss Kie, and I'll feel better right ahead." Yiggrit's smile stayed and he put his hands on hers lightly.

"Hahahaha, I'm sure of it now, even with the reputation of being a pervert, I'm sure you'll be quite popular when you grow up, if you keep it up, that is, so no slacking off, then." Kie held his hands after laughing at his words before replying wholeheartedly, their bodies getting closer by the second.

Right then Hanako came back with a tray containing a tea set, and a few snacks.

Upon seeing her mother, holding hands with Yiggrit while having a smile on her face, the young girl could only stop in place trying to read the situation.

"Mom?…" Hanako uttered not knowing what else to say.

"Ah! Hanako, ahem. Put the tray on the table and go help Nezuko with her chores." Kie pulled her hand back, before coughing with a blush and then readjusting to rebuild distance.

(Oh, such a pity, just when we were starting to get along. No problem, we will have a lot of time to get closer later.) Yiggrit lamented before he was laughing inside.

Not having the words to say at this moment, Hanako's first reaction was just to do as she was told and put the tray down, before giving them another look for a few seconds, then she left.

Once she left, the atmosphere became awkward in silence.

"Yeah, but just as you were saying, Tanjiro is something else, I wish I had his drive to be what I am despite the world around me. He's a kind soul, and that's what he does, and while I'm pretty confident in what I am, I don't know if it's to that level." Yiggrit casually changed the subject without acknowledging what just happened.

There was a moment of silence before she shook it off and responded.

"Tanjiro is a strong boy, I'm very proud of him, and I'm happy even a good kid like you can see that." Kie smiled happy to hear such things.

From there, they engaged in a much more casual discussion, that never got anywhere near as 'close' as before, drinking tea and eating the snacks.

Then came Nezuko, who looked at her mother before saying.

"I finished everything, and since Hanako fell asleep I took her to bed." She said as soon as she came into the room.

"It's been wonderful just talking to someone after so long, but I have to go put Rokuta to bed, I'll leave you two to talk." Kie got up and took the boy in her arms with her.

"Mom?…" Nezuko tried to protest, but it was too late, and her mother had left, so she turned to the boy in the room with her, and sat across from him, watching his everyone movement attentively.

"You're quite the hard worker. I guess that's a family trait at this point." Yiggrit commented, a small smile on his face.

"… I do what I can. It's just mom now, so I have to." Nezuko responded dryly, in a monotone.

"I can see that. Good job, you're making it easier for the rest of your family. If I still have mine, that would have been the way to go." Yiggrit continued seemingly unbothered by her attitude.

"Of course…. But is it just you? Nobody else?" Nezuko frowned upon hearing that, finding herself asking.

"Yup, lost my family in an incident. I was the only one left, so I started walking away and before I knew it, I was far from anything familiar. It was time to start, over, and I guess that went well. I've been doing that kind of wandering my whole life since then." There was a mix of half-truths in his words, though

it was not exactly that way, he wasn't lying just adapting the truth of his life to fit this new world.

"… That's awful, even if you're a horrible disgusting pervert, nobody should go through something like that." Nezuko showed her sympathy, feeling quite bad for him.

"It's in the past now. I met a great old man who ended up becoming a sort of grandpa, and I even had a great friendship with his grandson, though he turned out to be a terrible snake of the worst kind." Yiggrit smiled and spoke with her.

"… I'm happy to hear to had someone, but what happened? What did he do, why did you leave? If you found a family, why not stay with them?" Nezuko got curious about it and asked.

"It's a bit complicated, but the gist of it is that he betrayed me, and that made it hard for me to face the old man at all, so for a long time, I didn't see them.

"Then recently, the old man was about to die because of old age, so I visited him again, and he asked me to take on his legacy, and forgive my ex-friend. Now to fulfill the first thing, I'm back to wandering and that led me here." Yiggrit explained a modified version of the events that led him here, though it was mostly accurate to what happened.

"Hmmm… Wait? You didn't forgive your friend? Why not? Wasn't it your grandpa's last wish? What he did couldn't have been that bad, right?" Nezuko questioned confused at him.

"It was pretty bad, the kind of thing most guys would never forgive, I guess someone like Tanjiri might be able to, but I'm just not that forgiving." He shook his head not elaborating.

"That's bad, if he's the last family you have, it doesn't matter what he did, you should get along, after all, he's all you have left." Nezuko insisted unconvinced by his words.

"Maybe someday when I tell you what went on, you'll change your mind, but now unfortunately not the time for that." Yiggrit shrugs his shoulders.

"Terrible, you're making a grave mistake and you'll only see it when it's too late. What happened won't change how I feel about that." Nezuko was adamant and fully confident in her stance on this matter.

"When you have a nice family I guess that would be your perspective, but even if I did talk to him, or forgive him, I would still be here, I'm here not for hate, but because I have my goals and a legacy to strive for." Yiggrit expressed.

"If that's the case, I guess it's not as bad, even if I still think you should mend things with your friend… But it's enough of that. If you don't mind telling me, what are you even aiming for? That has you traveling like this." Nezuko once again got curious.

"I don't mind at all. I want to build my own harem family after I've made a name for myself, and even build my territory at some point. I want to learn all the arts and leave a great mark.

"Finally, I want to master the technique my master created, and even the one that inspired his. That's why, I need to see the world." Yiggrit revealed casually, unafraid and unapologetic.

"… You have a lot in your mind… Way more than I expected… Maybe a little too much for one human life… Wait?! You said Harem family?! What's that supposed to mean?!" Nezuko leaned in with a frown across from the table upon noticing he said that among his other more serious-sounding goals.

"It means what you think, I want a harem of women. Infinite women, as infinite as my greed, I want everything. I'll conquer and take until I have it all." Yiggrit responded as if it was the obvious thing to say.

"… You animal! How can you say something so disgusting with a straight face?! You're the worst kind of man! You know that! I was starting to think that maybe you're not so bad! But I was stupid, you're a horrible pervert! No! You're a monster, a monster among monsters, the worst of the worst!" Nezuko was angered by his words, looking at him with disdain, no, hate.

(She didn't take it well, maybe worse than I expected… Oh well, if I was not really for pushback, I wouldn't be me. Plus, this only means I left a great impression and she has strong feelings toward me, and feelings like those can be reversed.) Yiggrit raised an eyebrow not expecting a reaction this strong, but it was far from the end in his eyes.

"Fair enough, but that doesn't mean I don't need other things, I want male servants for war and stuff, and I'll make some friends along the way.

"So, let me ask you, do you think a monster like me, who's honest about his nature, or a monster who lies and hides his nature? Which one is worse?" Yiggrit asked calmly.

"… Erggh… Listening to you is very frustrating, but if I had to choose, I guess the honest one is better… I would rather never be manipulated by a monster like you. A degenerate monster is the worst, but a lying degenerate monster is even scarier." Nezuko admits though that doesn't soften her eyes toward him in the slightest.

"That's why I'm honest about my nature, I have nothing to hide in that regard. Though I still have some secrets of my own, don't we all?" Yiggrit said.

"Ewww, I can't imagine what a degenerate monster would keep a secret… I don't understand, if you helped so many people how can you look at women in such a horrifically repulsive way?" Nezuko's frown was ever present as she asked genuinely confused.

"I think you're misunderstanding me. I know it sounds that way, but I'm just the greediest, most lustful, and loving guy out there, I have so much of it, that it's infinite, and that's why I'll give it to infinite women to match it.

"While I will pursue any women who interest me forever, I won't add any of them to my harem until they take me, and I'll always be upfront about my intentions," Yiggrit responded full of confidence and fiery.

"… Unbelievable… I thought you were just the worst kind of guy, a degenerate monster, but it's so much sadder, you're fully insane, completely sick in the head." Amid the hate in her eyes, a form of pity could be seen as Nezuko looked at him.

"I'm, but that's my nature and I've chosen to follow it, regardless of what others think. I'll do things my way, and do whatever is necessary to achieve my goals.

"Though I want to achieve it all myself, through my efforts, not through some instant win button or whatever, I take buffs, help, and growth enhancers or other additives, it just has to be through my works, actions, and mind that I get there." Yiggrit nodded unfazed by Nezuko's words or perspective, he knows exactly who he is and what he wants.

(Just like the fireworks man said, go as bright as you can while you can, no more holding back, I'll unapologetically be me. I see it now, why old man Ruio would just act his way regardless of what others even I would say or think about him… Hahaha, to think I would become like this so easily, I guess I was always corrupt.) Yiggrit concluded a smile widening on his face as he relaxed feeling great to be him.

"… I think you're a disgusting insane pervert, a lunatic degenerate monster, so please leave my house and never come back! If I didn't know you help people and haven't done anything evil, I would truly hate you, but please leave!" Nezuko's frown deepened as she could not understand the one before her in the slightest.

"Nezuko? What are you saying? I heard yelling and I came to check since those two finally calmed down." Tanjiro came into the room looking around in confusion.

Seeing him, Nezuko said. "Oh, it's nothing much. Yiggrit said he was leaving today because he has a lot to do tomorrow, right?"

(So, you're not telling on me? Such a considerate girl. All this because I helped the village by accident… It's like when you complete a side quest first and then you find a main quest that needs you to complete it, but since you already did you just get to keep going.) Yiggrit thought to himself surprised she wasn't just yelling to everyone how much of a monster he was.

"Is that so, Yiggrit? Cause I could just go with you early tomorrow and help with whatever is necessary. It's very late I wouldn't want to have you go down alone after you went out of your way to bring me home. If you insist on going down, I'm going with you." Tanjiro said looking at the lunatic degenerate monster.

"No need, if you do, I'll have to bring you back again. I can take care of myself, I'm the best hunter around remember? It will be fine. Trust me." Yiggrit smiled at Tanjiro.

"Hmmm… Fine. Please be careful. I'll be passing by your house tomorrow to check on you." Tanjiro responded.

"You're too kind man, you almost make me feel bad for the kind of guy, I am. Please call your mom so I can say goodbye." Yiggrit sighed and got up.

A nod left Tanjiro and he went inside.

"Thank you for cooperating... You confuse me… I hate the way you think, and the things you say, but then you act like this... It would have been easier if you just acted as scummy as you think." Nezuko complained looking at him with narrowed eyes.

"I'm Yiggrit, don't try to lump me into any of your notions, I'm me above all else," Yiggrit said with an unapologetic expression.

There was no response from Nezuko who just looked at him as if she was looking at an incompressible puzzle.

"Here is Mom!" Tanjiro came up and then opened the way to present his mother as if he was announcing a world wonder.

"Yiggrit dear, Tanjiro told me you want to leave, but please do me a favor and stay. You've already come up here this late, going down without proper rest would be too much." Kie said not wanting to let him push himself too much.

This caused him to look at Nezuko before looking back at Kie and then.

"Just stay! It's not that big of a deal anyway." Nezuko gave in after seeing the insistence of both her brother and mother.

"Then thank you for your hospitality I-…" Yiggrit smiled as he was answering before he was interrupted.

[Warning! Challenger! An abnormally immense source of chi is nearing this house. There is a 98.7% chance it is Muzan.]

(I guess it's time for the show.) Yiggrit smiled to himself.

The time for the showdown had come.
