Rias blinked at that, "What do you mean? Like, your money? I have no interest in taking your money."
"Not just my finances, but my skills, knowledge, abilities, anything like that. You're not allowed to take my stuff or demand it in other ways. Same for the peerage. In fact, consider anything I request as applying to your peerage."
Rias frowned, "I'd never take things from you, though part of why I wish to recruit you is your knowledge. I wont demand it, but I would ask that you use what you know to help everyone grow stronger together."
Junichiro nodded, "That's fine. I'm not opposed to teaching you all a thing or two, or even giving you ideas to explore on your own. I'm not trying to be some dick who wants to keep everything to himself. I'm just trying to protect myself. I have things I can't have exposed and I need to guarantee that I'm protected if I join you."
Rias wasn't sure what he had to protect, but she could understand his desire to protect it, "Anything else?"
"I'm not your dog." Seeing the look of objection appearing on Rias's face, he rode over her, "While I know the Gremory family supposedly treats their peerage members like family, I want my rights protected in writing. Unless something changes, I would prefer our relationship to be more like a business arrangement where you make requests and I choose whether to fulfill them or not. I'm a busy individual and there's a lot of things I probably wont want to bother with, like going to school."
He leaned back and crossed his arm over his chest, but that was goddamn awkward so he put it back down and fidgeted, "I'm big on free will and I will not join your peerage unless I can maintain my free will."
Rias still looked slightly upset but nodded her head, "Fine, anything else?"
Junichiro leaned back and thought, "One last thing, I wont join you right this instant." Seeing her pouting and looking disappointed, he continued, "First, I want our contract in writing and I'm sure that will take time. Second, I want to spend some time as a provisional member. Meaning, I want to spend time with you and your peerage getting to know you all without making the change. It's all well and good to be told by outsiders that the Gremory's are nice, but I want to see what you're like up close and personal. I'll even take time out of my schedule to spend time at meetings or whatever it is you all do."
He gave Rias a stern look, "That last part is completely non-negotiable. I will not join your peerage until I know you and the rest better."
When he first arrived he'd been single minded about wanting to join Rias's peerage and while he would still like to do so, he wanted to make sure she was what he expected. If she was too different from his expectations, he wouldn't join her peerage and would find an alternate path. Maybe see if he could talk his way into Serafall's peerage.
Rias sighed but nodded, "I understand, and I don't have any issue with any of your requests."
She didn't have any issues with them, but they made her extremely curious. It was obvious that Junichiro was protecting himself and more. She wanted to know about the more. What did he have to hide? It was a mystery and one she wanted to solve! She was willing to bet it had something to do with how he talked about his missing arm. She wasn't sure what it would take to make a working replacement arm, but it had to be a lot of work!
Junichiro leaned forward in his chair, "If there's nothing else, I'd like to get back to work."
Rias pouted at the dismissal, but let it go, "Alright. If you want to see what we're up to, come to the old school building at Kuoh tonight. We have daily gatherings after school before everyone goes out to try and get clients, or to fulfill one of the few requests we're getting. I'd like for you to see the process and how we're building up a client base since we just took over this territory recently."
Junichiro nodded in acceptance, "I'll be there."
With that, their meeting broke up. Junichiro led Rias and Akeno out, noting that Akeno had been silent the whole time. He thought it was a bit unusual until he thought about the nature of the meeting. They weren't friends and it was a business meeting, it would have been completely inappropriate for Akeno to be her usual teasing self. Rather, silently supporting Rias and being nearby to fulfill her requests seemed more appropriate for a Queen. in other words, it was completely unlike the Akeno he was familiar with in his memories. Rias probably said something to keep Akeno in line.
After escorting the pair out, he returned to his workshop where his arm was laying out on a table completely disassembled. Scattered around it were various bits and pieces that made up the shell beneath the Doppelganger Flesh, the flesh itself, and the blood red metal that made up the bones in the shape of actual bones.
Junichiro smiled as he picked up a metal box containing thin strands of the same blood iron that made up the skeleton of the arm. The strands were slightly thicker than a hair, but not by much and there were thousands of them. He'd been working on producing the strands for weeks and if one were to examine the strands under a microscope, they would see an array of runes carved into each one.
The last item on the desk was a very thick book that showed a picture of a human arm stripped of its skin to reveal the musculature beneath. He carefully studied the medical text while gathering strands and arranging them in bundles with telekinesis. The work he needed to do would be far too delicate to attempt bare handed even if he had both hands to work with.
