Well, she wasn't a Demon Slayer.

'I sense something in her, but she isn't a Demon Slayer, so I'm fine with this.' Shizuku didn't care about the new roommate, she had no room to really complain about it either. The girl had her own room, she was polite and rather quiet, and most important... not a Demon Slayer. That was perhaps the biggest thing, Naruto was one of the rare good Demon Slayers, but she didn't know if she could handle being surrounded by Naruto's kind and keep her sanity.

Kuroka was pretty neutral to Asia.

The girl was young and actually innocent, she was no threat to her plans in the slightest. The only slight annoyance there was to the girl, was the fact that she was a believer... and a far heavier believer than Naruto. During dinner, she had prayed to start the meal... and while Kuroka was powerful enough to lessen her headache from that, but it was a slight twinge to have somebody pray over her food.

Oh, not to mention the girl carried Holy Water... nevermind, Naruto did that as well, but mostly because of his ghost fear.

"Okay everyone, I'm going to take a bath now... but I am laying down some ground rules now." Naruto came into the room from the bathroom, he had turned the water heater on so that it would be a nice hot bath. With three people living with him, though he should have done this with Shizuku and Kuroka both already. "Shizuku, keep your room dry until we water proof it... and don't mess with the pipes. Kuroka, you know what you do that gets on my nerves... and Asia... you seem nice, so I don't think we'll have any problems." Naruto rubbed the back of his head.

Asia seemed like a kind person, who would do what a good roommate would do, clean after herself and help out. He was going to teach her Japanese, so she couldn't exactly help with errands without him with her. She was going to be pretty bored honestly, since watching TV wouldn't do anything for her. She couldn't read any of the books that he had, other than the few English books he owned that didn't translate into Japanese well... so he bought them in their original language to read them properly.

"I'll try and not be a bother." Asia looked around the room at everyone.

Shizuku just ignored her and went to turn the TV on, seeing as she had just gotten into a TV drama and she wanted to make sure she wasn't going to miss it. She waved to Naruto, his rules were fine with her. If they were going to waterproof her room, then she could wait a few days to make it moist.

The doorbell rang.

Asia blinked, and like magic Kuroka was gone, as if she had never been there to begin with. All that was there was a black cat in her place, but neither Shizuku or Naruto blinked at that, so she tried not to think about it.

"You can be a bother, I don't mind too much... you can't possibly be a bigger annoyance than my resident Nekoshou and Mizuchi." Naruto glanced at the two pains in his ass. His gaze was a little affectionate, since he did enjoy their company a little... but he wasn't quick to forget what they did to his dick.

Naruto opened the front door.

He closed it.

"Who was it?" Shizuku asked him without taking her eyes off the TV. Naruto opened the door again, and saw Rias standing there with a bottle of sake. She had taken his words literally, though he had meant them literally. The fact that she already knew where he lived... no doubt thanks to Koneko... made this a lot easier on him.

Rias waited a moment.

"... Come on in... you really should send a text before you come over. Sorry if this place is boring... just moved in." Naruto had shut the door on her purely out of instinct. Despite what he said, he still hadn't really forgotten that she had tried to manipulate him.

Rias' eyes widened when she saw a kotatsu in the middle of the living room, with Shizuku sitting at it lazily, watching TV. It wasn't cold outside or anything, but neither was the kotatsu turned on either. Still, she had to stop her excitement at seeing it. She walked into his home, and he was right that it was mostly bare... there was a kotatsu, a couch, and a TV in the living room... and that was literally it.

"I went and bought the best Sake I could find. I figured, this would be my way of apologizing for my manipulations... and to show my sincerity in starting anew." Rias spoke as she walked over to the couch, but she sent a look of desire to the kotatsu.

...

"You can sit at the kotatsu you know." Naruto mentioned, and there was no more hesitation as Rias got down on her knees, on a provided pillow, and sat at the table with a wide smile. Naruto raised an eyebrow at her for that odd behavior, since she seemed a lot more... childish than when she was surrounded by her friends. "Asia, in the kitchen cabinet I have a black cup with a golden whirlpool on it... and a large black and gold bowl... you mind bring them." Naruto asked her as he sat down across from Rias, after he shut the front door, and walked over to her.

Asia was a little surprised, but she nodded and quickly walked into the kitchen to go and get what he was asking for.

"Okay!"

"Oh, and can you fill the bowl with water please?" Naruto called out to her, though he didn't know if she heard him. Naruto turned and stared Rias in the eyes, and she placed the sake down on the table. "You know, once we have exchanged sake, if you try and manipulate me again... you'll get no more chances. I will be your enemy forever." Naruto told her with a dead serious look.

Once you drank with somebody, that was a bond, and they were going to be forming a bond over second chances. This was her second chance, and his second chance. They would be becoming friends in the most official way possible, if she went back on her word... then she was breaking this most sacred of bonds.

"I understand... and I think I should be honest. I'm not human... and before you ask, I'm not a youkai either." Rias mentioned to him as Asia came back into the room, carrying a well sized bowl filled with water, and a single cup with it. She sat the bowl down on the table, and put the cup in front of water.

She looked at Naruto with some curiosity.

"... So... what is this for?"

"You know how in our faith, we drink wine to symbolize the blood of Christ, to further cement out bond with him?" Naruto asked Asia, and she nodded her head very enthusiastically, fully understanding the way he was explaining it. She used to be given sips of wine all the time, every Church service, so she was very used to what the ritual represented... even if the way Naruto explained it was a little off. "Well, I'm about to cement a bond with this girl... Rias... pour me a cup of sake." Naruto passed the cup to her.

What she was explaining could wait.

Rias took the offered cup, and gently poured the sake in it until it was completely filled. She pushed the cup back towards Naruto.

"I thought the Yakuza used two cups-"

"This isn't the Yakuza ritual, that ritual is accepting somebody as your subordinate... and it is different. This is different... are you promising to be honest with me, to stop manipulating me, and show me respect... on this sake and your name of Gremory?" Naruto asked her before he accepted the cup she offered him. His eyes were like cool fire, burning with a bright blue intensity that made him look like a burning blue sky.

She was almost lost in their intensity for a second, but she nodded her head.

"Yes." She spoke simply, in a way that she could not manipulate the words to mean anything other than what he said. She was going to follow what she said, he had just made her swear it on her family name after all. Even if she would live longer than him, the shame that she would bring to her name of Rias Gremory would never be forgotten by her. "I swear on my name as Rias Gremory." Rias cemented it further.

Naruto nodded, and he grabbed the cup, before he drained it of every drop of sake in it. Naruto turned the cup upside down, rinsed it with the water in the bowl, before he turned it upright and poured her a cup of sake.

"Okay then, on my name Uzumaki Naruto, I'm going to swear to give you friendship, honesty, and show you respect equal to what your actions deserve." Naruto pushed the sake cup to her. She looked at it, and her eyes narrowed as she tried to think about how he worded that.

Asia was just watching in fascination at how this ceremony was done, this was a very nice ceremony of the nation she was in, and she was watching it first hand.

'She's hesitating.' Shizuku thought, still not taking her eyes off the TV.

It was getting to the good part.

"Respect equal to what my actions deserve?" Rias asked him, since that seemed like it would be very... flimsy to her.

"Respect it earned, not just so easily given. I'll give you friendship and honesty, but my respect needs to be earned. You agreeing tot his, I'll respect this action... and I know you've researched what I've done in the past... you know what I've done to get respect." Naruto told her as the sake sat in front of her. She needed to drink it, to fully cement their bond and promises to each other. Only once she had done that, would their promises to each other be fully formed.

Rias gave him a bow of understanding, now knowing what he meant, since she had looked into him. She knew that he was a good person, though rough around the edges, and he helped a lot of people. He now had a small army of purely people he inspired with his actions, that was deserving of respect.

"Very well then... I'll accept your friendship, honesty, and earn your respect as your friend." Rias copied him, drinking from his cup until empty, before she washed it and set it down. "Naruto-san-"

"You can now call me Naruto, we've drank sake together... we've been bonded." Naruto stood up and offered her a hand up. While Koneko had earned the right to call him his name by impressing him with her character, Rias had earned it by forming a bond that should not be broken with him.

Shizuku snorted.

Rias took a deep breath.

"The bath should be ready, whatever you were going to explain, can be explained while washing my back." Naruto told Rias, and she blinked in surprise at what he was saying. She opened her mouth, and closed it like a fish.

Asia turned a little red when she heard him say that, but Shizuku just scoffed, since she had already washed his back before.

"Why?" Rias asked him, not against it, just wanting to know why she would be doing that. "Is this part of the sake ceremony?" Rias believed herself an expert on Japan, but this was kind of new to her. Was the sake ceremony more detailed than she thought it was?

Naruto turned around and gestured to his back.

"It isn't part of the ceremony, consider this a test. If we are coming clean, then we should bare it all." Naruto spoke, not telling her that he was doing this to give her a chance to prove her honesty. With his back turned to her, he would not be able to look into her eyes. He wouldn't be able to see if she was lying to him, at least she would think that. If she was going to follow her word, then she would be honest with him, even when both of them were naked, and he couldn't watch her.

If she passed this test, then she would truly gain his respect.

"Okay them, lead the way." Rias would be happy to take a bath with him, she felt no shame for her body, and she wasn't shy about nudity. If this was what it took, then she would do that.

-Inside the Bathroom-

Rias was a little surprised when she saw Naruto's back, for a guy a noticeable amount shorter than herself, his muscles were developed well. She could feel them, washing him with her hands, and it was like touching comfortable iron. Fleshy iron that could either give way to her fingers, or reject them depending on if he was flexing or not.

"I'm neither human, nor youkai... in this world, multiple different pantheons exist... I exist as a creature from the Christian sect... I am a High Class Dev-"

"Devil of the Gremory clan, one of the 72 demons that were controlled by King Solomon to build his temple." Naruto mentioned as he glanced back at her. Rias blinked in surprise, before she nodded her head. That had been pretty easy, it would seem he was partially aware of that.

"You know about the Underworld?"

"Serafall Leviathan... Sona Shitori... Sitri... Gremory... did you think that I wouldn't notice what all of your last names were. You're all supernaturally aware, and have the last names of the 72 demons. I'm stupid, but I'm not clueless." Naruto mentioned to her, unsurprised that she was a devil. Sure, he had just had a theory on it, and he had believed that she was human until she proved his point... but the context clues were all there.

Rias just smiled.

"So, you're not going to judge me for my race?" Rias asked him, since her very existence kind of went against his religion.

"I've looked into your eyes, you are manipulative... but not a truly bad person either... I'm a Demon Slayer, and live with youkai... I'm going to judge you by your actions, not your race." Naruto told her, and she nodded her head. He was smarter than she gave him credit for, with his poor grades she had expected him to be an idiot who couldn't read into a situation. "Though, until you admitted to not being human or youkai, I didn't know for sure." Naruto could feel her breasts against his back as she washed his shoulders.

She had very large breasts.

"Well, I am the heiress to the Gremory clan. I came to Japan to learn about the supernatural creatures of Japan. You live in a very fascinating country-"

"You're obsessed with Japanese things, aren't you?" Naruto questioned her with a dull tone.

...

"... I watched a lot of anime my brother gave me, as a child... and it got me hooked on Japan." Rias admitted with a blush on her face. She saw him glance at her in the mirror, giving her a critical eye, before he closed his eyes and grinned a little.

'Now that was some honesty... and she didn't want to admit to that.' Naruto thought, impressed by her. Admitting to something embarrassing was a lot harder than explaining something you had time to prepare for. If she was willing to admit that little secret about herself, then he could give her the benefit of the doubt from now on. "I believe you... you can ask me anything you want while I'm washing your back now." Naruto poured water over himself, and turned around to stand up.

Rias was given a close up view of something she hadn't been expecting, but she just nodded to Naruto and moved forward so that he could get behind her.

"High-class Devils like myself, form peerages of people we turn into Devils like us... would you consider joining a peerage?"

"I'm going to stay human. I was born human, and if I have anything to say about it, I'll die human."

"Your lifespan will be a lot shorter than your supernatural friends." Rias pointed out to him, and he just grinned.

"Then, I better make the time I spend with them, all the more memorable for them. Friendship isn't measured in years, it is measured in memories. If my lifespan ever becomes an issue... then I'll just conquer human mortality... I'll become so powerful that I'll defeat death itself." Naruto flexed and arm, but he started to gently wash Rias' back. He raised an eyebrow when his finger touched the side of her neck softly, and she gave a shiver and moan.

Her neck was a sensual spot for her to have touched?

"That is really mature." Rias had never thought about it that way before.

"Not really, I've just come to terms with the fact I could die any day because of my looks, and how I act... I'm not going to change myself, and I'm going to live the way I want to live." Naruto was sick of people forcing their ideals onto him. He was going to live his life, the way he wanted to live it.

If life threw him a bad hand, he would fighter for a better one.

"Living the way you want... what about love and marriage?" Rias wanted his opinion on that.

"I don't know anything about that... but I do think you should only marry for love." Naruto shrugged his shoulders, her question was a little out of nowhere.

"... and sex before marriage?"

"If you love a person, sure... but I personally think sex should be saved for people you share a strong bond with. I even believe that friends can have sex, if their reasons are good enough... but two random people doing it... I just think that ruins the mood a bit." Naruto couldn't imagine himself picking up a hooker. He could only ever see himself doing it with somebody he formed a bond with. He could see himself having sex with Kuroka or Shizuku, now that his bond had been forming with them.

For him at least, sex was about more than simple pleasure, which was why he was saving his first time for somebody special.

"Hmmm... most men don't share your opinion. They seem willing to throw their virginity away at a moment's notice... they seem to want to throw it away." Rias admitted that was part of why she had a low respect for most men. Akeno was much the same way, neither of them really liked men because of it. Some people stood out though, and earned their respect.

Naruto seemed more interested in fighting Koneko, than he did having sex with her, which had gotten her attention on him in the first place.

"Different people have different views, I'm a virgin... and when I stop being a virgin, I want it to be an experience I'll never forget. How about you?" Naruto asked her, and she shook her head.

"I'm indifferent... I know people value my body, but it's just my body. If I need to use sex or sex appeal to further my goals, I'll do it..." Rias watched Naruto's reaction, and saw that he wasn't giving her a glare, or trying to make her rethink her thoughts on it. "Though, if I ever get to fall in love, I might change my views." Rias admitted to him at the end.

He just shrugged his shoulders.

"... What?"

"Not going to judge me?" Rias asked him with a knowing smirk.

"I can kind of respect your opinion. Prostitution is the world's oldest profession, I'm not going to shame a person who has different views on it than me. Like I said, I just think you should have a bond with a person... it doesn't have to even be romantic love." Naruto admitted that his own views were a little flexible. He would never have sex with a prostitute, but if one of his female friends he shared a bond, asked him if he would do it with them, if they could give him a good reason, he would do it.

He just wanted his first time to be special, and helping out a friend was something he could consider special to him.

Rias just sat in silence, before she was done having her back washed, and she stood up to get into the tub. She and Naruto both got in, and sat in silence for a couple of minutes.

"I'm a virgin... just so you don't think I'm a slut or anything." Rias continued their conversation. "I just don't hold a strictly sexual view on the matter. I do hope that I can have my first time with a man I love... but if not, I won't be heart broken over it. There is just one person I don't want to have sex with..." Rias was just noticing it, but being naked and speaking frankly, was getting her very relaxed with Naruto.

Who knew being naked could be so liberating emotionally?

"... Let me guess, arranged marriage?" Naruto asked her, finger guns pointed at her.

"Got it in one... my parents, before I was born arranged me to marry into the Phenex clan to produce pure-blooded children and strengthen the bonds between our families. My future-husband, Riser Phenex, is handsome, smart, and I respect his strength and status... but he is arrogant, and views me as nothing but a trophy." Rias leaned back, boobs floating in the water, and closed her eyes as she told him everything about her situation. It was nice to get some of this off her mind, and maybe get a second opinion on it. "... I don't want to be married to a man who I will never love, and won't love me. I wouldn't mind if we could just have sex once, get me pregnant with his child, and never see each other again... but our parents want us to marry." Rias spoke with a frown.

If it was just something as simple as having a child, then she could do that. Have sex with him until she was pregnant, bare a child that would link their families together, and then part their separate ways. She could give birth to a child, and then go find a man she could actually fall in love with, and never speak to Riser again.

"... Low fertility rate right?" Naruto asked her, and she nodded.

"Two for two there... Pure-Blooded Devils are lucky to give birth to a child every hundred years... the Phenex seem to be lucky, and produced several children in the last century... I have a brother who is several hundred years older than me. I'm jealous of you humans." Rias spoke of one of the downsides of being of her race. Even reincarnated Devils suffered from a lower fertility rate, both male and female, to the point that it was just hard for them to get produce children. "I actually proposed my idea to my parents. You know, give birth to his child, and have nothing to do with him anymore."

Naruto raised an eyebrow, and looked at her.

"They didn't go for it... let me guess, having children out of wedlock isn't looked well on." Naruto guessed, and she splashed the water with her hand a little.

She nodded.

"You're good at guessing... my family didn't go for it. They said it would be disrespectful to both families... and I don't want to bring shame to my family... I hate it... but if I can't think of a way out of this, I'll have to marry him." Rias mentioned, and Naruto just raised an eyebrow at her. "What?" Rias asked him, and he just shrugged.

"I mean... have you ever thought of just... talking Riser and telling him you will never have sex with him... even if you marry him?" Naruto asked her, and she looked at him. She motioned with him to continue, and he nodded to her. "Well... that guy isn't going to want to get married to a girl that will refuse to sleep with him, from the sound of it. If both of you refuse to marry, wouldn't that just end it." Naruto mentioned to her, and she scoffed.

"As if that would matter to him."

"Is rape illegal in the Underworld, because if you refuse to have sex with him, and he does it... he's not going to want to deal with you as a wife." Naruto waved a finger around knowingly.

She blinked a few times.

While it was true, a High-Class Devil could do anything they wanted to their servants, from rape to murder... She herself was also a High-Class Devil of an important family. Riser couldn't afford to sully his families name by something as serious as this.

"I see... and if he still wants to have marry me?" Rias had a growing smile on her face.

She had never even thought about just telling Riser, that even if she married him, she would force him into a sexless marriage. Knowing him, he would be totally against that, and wouldn't want anything to do with her because of it. Naruto had a great point, and she would never had thought of it if she hadn't become friends with him.

"Tell him that you'll marry him, but sleep with men behind his back... I mean, it's not like he can prove it... he'll be forced into a marriage with a woman sleeping behind his back. He can't go to your parents, or his parents about it either... because he is arrogant... he wouldn't want it to get out that his woman is cucking him." Naruto thought of an easy solution to that. Rias' eyes sparkled with inspiration thanks to his words though.

She splashed a ton of water out of the tub, as she rushed forward and gave him a giant hug.

"You're a genius, thanks Naruto!" Rias gave him a big kiss on the cheek. She stood up, slapping his face with her breasts, before she ran towards the changing room. "I've got to go and contact my parents, to have them set up a meeting between Riser and me." Rias closed the door behind herself.

Naruto was just confused, holding the cheeks she kissed with growing confusion.

Why was he a genius?
