"Now, I can't help but appreciate this view... and I'm not staring at your ass."

Naruto's words were directed towards the food stand, a food stand outside of the convention that was serving ramen. A apparently popular dish in this area, since they were only 5 minutes away from the ramen museum... something he wanted to visit some other time when he wasn't dressed as a male stripper with an exhibition fetish. He had the chance to stare at Koneko's ass, and she did seem to want him to stare since she made sure to constantly stand in front of him.

'Jerk, I've been giving him chances all day to touch me.' Koneko thought a little bitterly.

Why wasn't he realizing that she was offering him up the chance to molest her, have a little fun before their night together tomorrow? She wasn't trying to seduce him, she just wanted to use his larger body to hide her from behind, and give him a chance that she wouldn't get while surrounded by the other girls.

Where was Bennia?

"I sent Bennia to the house, if you're wondering about that. She's going to be rooming up with Kuroka from now on." Naruto told her once he saw her glancing around, no doubt looking for somebody.

-At the Uzumaki Household-

"Hello, I'm Bennia, I'm the new member of the harem. Naruto said that I could live here from now on."

Kuroka blinked in surprise when she opened the door, seeing a Grim Reaper was standing with two suitcases of her things with her. She had a chipper, upbeat sound to her voice that was a little confusing. Bennia put her things down, and grabbed onto Kuroka's hand with both of hers.

"What-"

"You must be my harem-sister Kuroka, nice to meet you, we're going to be Pussy Cousins soon enough after my trial period. I'll be rooming up with you from now on." Bennia let go of Kuroka and grabbed her suit cases again. She walked passed Kuroka, side stepping her, and into the house. Asia was sitting at the couch with Shizuku, who was helping the girl go over her Japanese lessons. The girl almost had the language down, other than a few small issues, she could hold conversations in Japanese now. Though, she wasn't really able to read or write very much in the language as of yet.

In about a week or two though, she should be ready enough to start going to school.

"... Nya the nya?" Kuroka was genuinely confused by all of this.

"She's Bennia, Naruto gave her a Harem Interview to be one of his romantic partners ya know. She's going to be rooming with you, second door on the left. Dinner will be in a couple of hours ya know." Shizuku confirmed for Kuroka, who was looking at her like she was stupid.

She was going to believe this girl at face value?

"You can't be serious nya." Kuroka looked at her phone, that she kept in her sash, and saw that she didn't get any messages from Naruto. She looked at Shizuku, who held up her own phone and showed the message from Naruto. "Why does he send you messages like that nya?" Kuroka didn't understand why she wasn't sent a message.

"It can't be because I'm a responsible adult, though erotic, who takes care of the house and makes sure everyone is well-fed healthy food ya know." Shizuku's snark was real as she gave a smirk right at Kuroka. "Asia got the text too ya know." Shizuku stated, and Asia blushed, before she nodded her head and showed her phone, that had a message from Naruto about Bennia.

'Ha-harem interview... should I ask Naruto about getting one too... or would I be overstepping?' Asia thought shyly, not wanting to make anyone angry, but... she did want to at least try to pursue something with Naruto. Surrounding by so many erotic women though, she knew that she didn't have much of a chance. Shizuku, as underdeveloped as she was, knew how to use her assets to her advantage to give off that feeling that Asia knew she herself could never do.

Kuroka was just sex appeal incarnate, and even Koneko had a unique erotic charm about her... this girl that just showed up was visibly not wearing panties, and had an unearthly beauty.

How could she compete with these supernatural fiends?

"Don't worry, right now I'm in a trial period, so I'm not able to request stuff like sex. Also, I'm straight, but since we have the same Harem King I don't mind threesomes and orgies with all of you... nice to meet you, you must be Asia." Bennia introduced herself by shaking Asia's hand to. The girl was confused like Kuroka, but far more red in the face at the way this girl showed no limits on her mouth. "... This house is awesome by the way, Shangri-La to honest since this place is Naruto's home." Bennia just breathed in the air, happy to be able to get this chance at all.

Shizuku was just accepting.

"I've been with a few girls in my time, so I'm fine with that too ya know..." Shizuku gave Bennia a glare though. Bennia wasn't even slightly intimidated by it though. "... Don't you think you can compete against me as a loli character though ya know." Shizuku already had Koneko and technically Asia to compete with, though Asia was just barely able to be classified as one.

"Am I interrupting something?"

"Oh dear Lord!?" Asia shouted as she fell over when she saw a head attached to a super long neck coming through the front, and still open, door.

It was the doctor, Toko.

Her body followed her neck moments later, shrinking in size until she had a normal neck. She had a large case with her, that was taking both of her hands to drag around. She was in her lab coat, as usual, she looked like she had just gotten off of work. Shizuku glanced at her, before she gave a silent scoff. An Ayakashi that fully integrated into human society was a disgrace if she had ever heard of one, even she in her now more tamed state, still refused to give up on her own heritage as a proud Ayakashi. Submitting and joining the human side of things was just... wrong of her.

"You're the Rokorokubi that Naruto goes and visits sometimes... you do blood work on him, and research Human-Ayakashi relations right nya?" Kuroka remembered this woman from what Naruto told her of her.

"I've made a very stunning break-through that I wanted to talk with Naruto about, is he home... if he isn't, can I tell you and have you pass it onto him?" She asked as she looked around, excited.

She had learned something very exciting.

Nobody stopped her from setting up shop and opening her case up, showing what she had brought with her. She had several red vials of no doubt blood, a microscope to view it with, two vials of white fluid that were donated by Naruto for her study. She had all of the vials labelled, several of them with Naruto's name on them. She sat down and took some blood out, before she showed it under the microscope. She gestured for the most intelligent in the room, Shizuku, to come and see it, so the girl did and viewed what was under the scope.

She saw blood with small fragments of energy in it.

"... I'm looking at something ya know?"

"This is Kitsune blood, and similar energy is bound in the blood of every youkai or ayakashi I've viewed so far. Of course, all youkai have a youki to them, it's normal... but this is the blood from the oldest one of the first ones to exist." Toko said as she switched the blood sample and showed it to Shizuku.

It was red... but it was practically pure energy, very little actual blood.

"... What are we looking at?" Bennia didn't know what was going on as she took her chance, and looked into the microscope herself.

Toko was happy to explain.

"What came first, the Ayakashi or the Demon Slayer... as you know, all Demon Slayers are humans... but did they get their powers from being descended from Ayakashi, or did they evolve and gain those powers on their own? Gods too, depend on Human belief for their continued survival, because when Humans stop believing in gods, those gods lose their powers and fade away... why though." Toko spoke with excitement in her tone. Naruto's blood had been a major clue to figuring out what she had been studying for years, since no Demon Slayer would ever willingly give their blood to her before.

"Really nya?" Kuroka didn't know that fact.

"Gods can vanish?!" Asia looked alarmed by that fact, and put her hands together in prayer.

"This led me to question something... why do Youkai, creatures hated by gods exist at all? The same with Devils, and why do all of the creatures hated by the divine seem to depend on human emotions and desires so much? After all, if gods created humans... and gods were here first, then why do Devils or Youkai exist at all?" Toko asked the question that she knew she would be the one to answer. "The answer is... it's backwards." Toko explained, she had wanted to save this presentation for Naruto, but she would show it off to them.

She showed a hand-held dry erase board, and showed the relationship between humans, gods, and youkai.

"... What/ya know?" The collective response was short.

"The original Youkai, before our blood became mixed with humans and we gained true genetic bodies... the bodies of youkai were pure ethereal energy, our physical bodies were just the manifestation of that energy. But, where did that energy come from?" Toko explained as she showed off the picture of the youkai, with a purple drawn body and yellow scary eyes. She showed purple energy coming off of the human, and going into the youkai, as well as a small picture of a spider. "The reason is really simple... humans created youkai by believing in them. It's human fear of the unknown that gave rise to superstition, and as humans believes that superstition, human emotions and spiritual energy birthed the first youkai... everything that humans feared, a youkai was born when enough humans gained a fear of it. We, all youkai now, are mere by-products of human emotion." Toko explained the true, suspected relationship between monster and human.

"... What do gods have to do with this?"

"That was a key here too... why are there so many gods, who are all credited with doing the same thing... but how can so many similar gods exist on one planet, one planet that every religion believes their gods alone created? It didn't make sense, but for such powerful beings, to also be reliant on human faith? It's simple... just like how human fear created youkai-" Toko pointed at the relationship between humans and youkai, before she showed a more golden energy connecting the humans and gods. "-human faith, humans believing in gods gave birth to the gods. Which is why gods do everything in their power to preserve the human race, because without humans, they will fade. Even the 'Strongest' existence known to us ONLY exists because of-"

"Human dreams nya." Kuroka's mind was honestly blown when she made that connection.

"Right, even the Great Red... no because it was birthed by humans. The arguably strongest Dragon, stronger than gods, was created by human dreams and their fear of the end of the world. This is evidence that humans belief has the power to change reality as we know it... and when the things that humans feared started to become real... humans who had an affinity for stronger beliefs started to manifest powers tailor made to killing Youkai... Humans created Demon Slayers in order to defeat the monsters that they themselves created!" Toko had reached an amazing understanding that many wouldn't want to admit, those who had a low view of humans especially. The technically weakest race, the race that also had the most potential to be the strongest race, was the one that created all of the other sentient races. "Think about it, all youkai can take a human form... all gods can take human form... Devils, Angels, Fallen Angels, all races have forms that are similar to humans... even many dragons are capable of magic to take human form." Toko showed more evidence, showing the blood of several other youkai and even normal humans.

"Why do you want to share this with Naruto?" Bennia asked with crossed arms, confused.

"Because, I was able to research his blood and semen, and I located what produces those specific energies that can create life. I tested and tested and tested and tested, until I found a way to mass produce them. I mass produced the human instinct that tells the body to reproduce, and turned it into a literal magical pill." Toko reached into her case, and pulled out a bottle of pills with no label on them.

...

She actually did it!?

"... But that-"

"With one pill, any Youkai who takes it will instantly enter their Mating Season, as the human's power over reality itself will modify the youkai's body in order to make it more suitable a vessel for life. If a youkai has sex while on this pill, there is a 100% chance of pregnancy, along with a practically doubled sex drive... I've tested on humans as well, but without the sex drive side effect... this pill can grant supernatural beings the the ability to produce by breeding... withthechildhavingahumanlifespan." Toko muttered the that a cough. She hadn't managed to work out a way around that, since the pill created life as if a human would, it negated the youkai or supernatural creatures spiritually long life span. Meaning any child born under the influence of the pill would have a human life span. There was also possible side effects like reducing the life span of the creatures, other than humans, who took the pill since it might negate the part of their lives that granted them amazing life spans... if the pill was used too much at least. If used responsibly that shouldn't be a problem.

Kuroka had the biggest smile on her face when she heard that there was a pill that could promise children without fail.

She would definitely pass this news onto Naruto.

In bed.
