He was just sitting there waiting for her.
Rias was surprised that he was willing to accept the Temp. Contract that Koneko offered to him at all, considering he had shown no interest in making a deal with devils. He seemed to have everything that he wanted already, so she wanted to put him in a position where he wanted something from her. Rias was wearing her casual clothes, but good ones so that she would give off her best appearance.
She wanted to try and renegotiate the deal.
Koneko was the one paying the price, when it should be her that paid the price for the contract. She didn't tell Koneko this out of respect for her wishes and sacrifice, but if she could at least limit the suffering that Koneko went through she had to try it.
She sat down in front of Naruto.
"Is coughing up golden magic normal?"
"Sorry?" Rias asked Naruto, and she noticed that he wasn't looking at her. He was writing down in his notebook. He was studying some golden magic fluid he had inside of a bottle, but she coughed into hand when she realized he wasn't talking to her exactly. He was just talking to himself. "Hello, Uzumaki Naruto, I am Gremory Rias... may I call you Naruto-kun?"
Naruto looked up, just noticing she was there.
"Sure, I don't mind weeb."
"Ex-excuse me?!"
"You're a total weeb, you think you can hide it, but there is a clear reason you came to Japan. After going through your room to learn a bit about you, I saw how much Japanese stuff you collect... You're a Japanophile after you?" Naruto asked Rias with a growing grin on his face. He broke into Rias' apartment room and looked around, and he saw just how obsessed with Japan that she was.
Her cheeks were bright red.
"I prefer Japan Otaku-"
"Rias Weebory."
"Not that... please don't make-"
"Weebis Weebory the Weeb Faced, Big Boobed, Weeb Devil. In all serious though, you're here about the Temporary Contract right?" Naruto asked Rias as he changed tones at the drop of a hat. He was done teasing her about her interests, but he did enjoy seeing her face go from pale skinned to bright red so quickly. "Do you accept the terms?" Naruto asked her simply, since that was what mattered to him.
"I was thinking of offering some renegotiations-"
"No, take it as it is or leave it. The contract right now is fair and balanced, with everyone involved with the contract giving up what they believe is equal. I'm giving my time and effort, and you are giving up a future contract, while Koneko who offered the contract is giving up her time and effort. The contract is fair." Naruto stated to Rias, crossing his arms.
It wasn't just that he didn't want to lose out on a willing test subject, it was also that he respected how Koneko had offered him such a good contract. Nobody lost anymore than anyone else when it came to what they were willing to give up.
"I believe that I should try to renegotiate to lessen the burden Koneko will carry, I wouldn't be doing my part as her friend if I didn't try." Rias insisted.
"I want to study Sona Sitri's body, get me access to her body and I will limit the amount of time I experiment on Koneko to 4 hours a day." Naruto offered the only thing that he was going to accept. He wanted to touch, fondle, and test out the secrets of a Sitri clan body. Unlike Rias and her peerage, Sona was much better protected.
She had a larger peerage, and she constantly had her guard up for anything that could happen, whcih included a small magical barrier around the School Council room that she was usually in. She put up a monster repellent barrier, so his monsters didn't like to go near the place and he didn't have the heart to force them to go there.
"Is there nothing else?" Rias would never be able to manage that.
"Nope... do we have a deal on the Temp. Contract?" Naruto offered his hand to Rias, and she took his hand with a sigh.
She tried.
He was firm and resolute though, and he wasn't wrong. Everything was putting up what they themselves were willing to surrender. Koneko had been the one to offer her body to Naruto, meaning that Koneko was willing to do this. She didn't have a reason to refuse the contract she benefitted from when the one reason she didn't like the contract was a willing participant.
"Just... please don't hurt her." Rias asked politely.
"No promises, she might accidentally get a little hurt, but I won't purposely try to hurt her, that I can promise. Now, tell me... what are your current options for getting out of your arranged marraige?" Naruto asked Rias, leaning forward and looking at her. She noticed he pulled a different notebook out and was flipping his pen in his hand.
"We're starting now?"
"Do you need a Potion to Negate Phenex Regeneration, or maybe you need me to design a monster to take his peerage out. What route are we going with this?" Naruto needed a basic plan if he wanted to fulfill his end of the contract. "The Phenex specialize in Wind and Fire, but their unique abilities are Phoenix Fire, Regeneration, and producing Phoenix Tears. How are you trying to negate the contract?" Naruto asked her as he waved his hand.
Rias was taken back by how seriously Naruto was taking this.
"Well, I was given 10 days to prepare for a Rating Game between my peerage last night. I was hoping you could help train my peerage, or give me some kind of secret weapon. Do you really think you can negate Riser's regeneration?" Rias asked as she leaned forward. She was unsure if that was even possible, but Naruto said it was with such certainty that she needed to assume that he could create such a thing.
Naruto nodded his head.
"Yeah, and all I would need is a single Phoenix feather soaked in the blood of a virgin and a slut. If I had that ingredient, then I would be able to create a potion that could give your magic the ability to negate Phenex regeneration for 24 hours." Naruto already had all of the basics for the potion in his mind. All he needed was that particular ingredient and he could give Rias a magic ability to negate regeneration for the Phenex.
Rias was just stunned, with her jaw slightly agape for a moment.
It was that easy?
"That is a very... particular ingredient to get." Rias then realized getting a phoenix feather soaked in the blood of a virgin and a slut would be no easy task. She needed to get, first, the actual phoenix feather. It would be easy to get virgin blood, but she didn't know any sluts and she wasn't friends with any people that might be sluts either. "Why do you need it?" Rias questioned him.
"The reason Phenex has the name at all is because they have similar abilities to the Phoenix bird. An actual phoenix doesn't regenerate from wounds, but instead is reborn by death. Virgin blood represents purity, but slut blood represents impurity. Combining them would create a contradiction in effects in a potion, which soaking a feather in that mixture would cause an effect that negates the magic of things in relation... did I lose you?" Naruto asked when he noticed that Rias didn't seem to be following him.
She shook her head.
"Actually, I'm very interested in this. I don't understand potion making, but it's a very interesting topic. I always hear about virgin blood, but I've never understood what it's actually useful for." Rias explained why she seemed to be so silent during his explanation. "You can't make monsters to help train my peerage too?" Rias questioned him.
Naruto crossed his arms.
"If I make monsters to train your peerage, I'm holding back. I notice that Gasper in your peerage... yes?" Naruto saw her raise a finger.
"You know about Gasper?"
"Yes, and I noticed his Sacred Gear is out of control. If you had his gear under control, beating Riser would be rather simple. Unseal him and bring him to me, I'll experiment with him and see what I can do about his control... I make no promises though." Naruto couldn't promise results with Gasper.
Rias put her chin in her hand.
"That... would be very welcome... but what do you gain out of it?" Rias asked him, since just making her the potion he talked about would get her the results she wanted.
Naruto crossed his arms.
"I want to see if being attracted to Traps is gay is my benefit. I want to do a research paper on it, and create a potion that will turn people into Traps. If I can prove traps aren't even slightly gay, then that will be a great boon to me. Of course, in payment for me experimenting with him, I'll try and see what I can't do about his Sacred Gear." Naruto offered her with a nod. "If you can bring him to me to study, at the very least I can try to help him. If you aren't allowed to unseal him, you can just seal him in my apartment instead... change where he is sealed." Naruto could see a possible problem since the Dhampire was sealed.
Rias smiled at Naruto.
"I'll talk to Gasper, and if he wants this, then I won't have a problem with it."
The deal was made.
Rias had no clue what sort of hell awaited her peerage.
