Menza grinned. The boy understood what this was all about and he wanted to get straight to the point. He was willing to consider payment which was a big first step. The one whom some call "Naruto Satan" wasn't keen on torturing Jinchurikki or their girlfriends but he was willing to do it, if that's what it took for him to understand the importance of settling one's debt.
"Straight to the point, I see. I like it. However, we aren't just talking about what I've done for you regarding Kyuubi although that is a hefty part of it. Perhaps, some background would be helpful...you see......I met Yui some time ago, well before this unfortunate incident with the Nine Tails. I did her a favor, for free, purely because I was interested in her development. I did tell her that if she wanted to engage my services again she could do so, but that it would be costly. She agreed. Some time later she called me. She wanted me to bring her brother back from the dead. He had passed due to the plague and was more or less rotting in the grave. Reviving him was no simple feat, but through methods I won't disclose I was able to bring her brother back. Last I heard, Taichi is in good health and Yui was satisfied with my services"
Menza took a sip from his tea but when he lowered it from his lips, his expression turned from jovial to fairly dark. The young man's eyes narrowed (as much as they could) and a glower settled on his face.
"Imagine my shock when I was called a second time to fight a Bijuu when I hadn't even been repaid for my previous work. Rin, there is nothing more aggravating than someone who takes advantage of my kindness. What I do is valuable and I don't do it for free. Yui owes me because she called me. Maybe you wish to take that on because you care about her well-being or maybe because you feel obligated to repay me due to the fact that you have personally benefited from my help. Your reasoning matters little to me. I have certain things that I need done and if you want to see Yui alive, you will do them for me."
Menza took a sip from the tea and closed his eyes. He was 100% dialed into his surroundings and was more than capable of defending himself from the Uchiha should he chose to attack in a fit of rage. The Cursed One was certain that he had agitated Rin given the fact that he had threatened his girlfriend. The influence of the Nine Tails was probably still fresh in his mind and he wouldn't be surprised if he had managed to provoke the beast. Good. If Rin went insane over such a small conversation then it was better to know his limits now. If he couldn't keep a cool head in a situation such as this then he was useless to Menza.
If Rin still had his wits about him, then Menza would open his eyes and lower the cup again.
"I have two tasks I need you to complete. The first involves the Sage's Tools. Iwagakure was the original possessor of these artifacts yet Konoha has seen fit to take them. I have my own plans for them and so I need you to steal these artifacts from your own village and deliver them to me. I don't care how you do it so long as you do not disclose the nature of our dealings to anyone. We will meet here in this very room for the hand-off. The second task will be a difficult matter, I need a living breathing Ōtsutsuki. These people are quite alien from us, yet they are so very rare. I wish to study them and in order to do that I need a living specimen. Unfortunately, most villages monitor them closely and so it would draw too much attention and ill will if the Society were to go after them in an open and brazen fashion. Having you do it for me would save me time and headaches. This is a personal project and I don't want others butting in. The leader of my organization can be so very uptight at times and I'd rather not deal with her religious ravings regarding fate, destiny, and duty. Likewise, you will bring the Ōtsutsuki to this house same as the Sage's Tools."
Menza looked Rin in the eye and spoke plainly. He wanted the lad to understand what was at stake.
"You have one month from today to get me the Sage Tools. If you fail to deliver them, I will capture Taichi Kotoshura and subject him to a degree of torture beyond even your Bijuu's imagination. Then I will kill him and deliver his remains to the Kotoshura Clan, piece by piece. You have three months to get me the Ōtsutsuki. If you fail, I will do the same to Yui. Although...."
He paused for a moment and a path of scales erupted near his neck and covered part of his face.
"I cannot promise you that you'll be sent her remains. Should you fail, I have other designs for your girlfriend's body and they don't include giving you something to bury. If you still fail to give me what I require, then two months later I will then find you and then I will take your Bijuu from you. If you manage to survive that then good for you....but otherwise I'll consider our business concluded. Remember that these deadlines will run concurrently and you shouldn't speak to anyone about our dealings. Make no mistake Rin Uchiha. It was fairly likely that if Yui hadn't called me, she would have perished. However, if you don't do as I demand I can guarantee you that she will. She is under my care for now but that can change in an instant....Am I correct in assuming you will do as you are told?"
