The second the Mizukage hat touched his head, Sharky Shark Whalberg decided he had enough leverage to drive a harder bargain. All the same, Shimiko nodded and listened with the same courtesy and respect he had afforded her. Kyoji retrieved the letter and set it on his desk. So they know... Kirigakure had read the letter that the Cloudian was supposed to deliver. It was a message to Natsuru telling her (or rather pleading with her) to utilize her bow and take out the Cloudian. If they had the letter, then they'd have the accompanying scroll with the bow inside as well. Shimiko was not keen on letting them have that. It wasn't the most epic bow in the world, but it was a personal gift to a friend. If Kyoji knew what was in the letter then there was no use denying that Kumo had intended to capture Ken with or without the village's consent. He mentioned that the Cloudian had swung by before and had been turned away. This was news to Shimiko. She didn't recall reading a report about this, but it provided some interesting insight. It still didn't explain why he had gone postal against an entire village. She knew he was strong but she knew he wasn't strong enough to credibly pose a threat to the entirety of their military forces by himself.
Kyoji reiterated that he disagreed with Ken's actions but he insisted that the man should be tried in Kirigakure. Once Ken was delivered to Kiri only then would they feel comfortable exiting the Land of the Demons. Shimiko extended and retracted her fan a few times after he finished speaking. She was considering her next words carefully. The Raikage wanted peace with Kirigakure, but she also wanted to use Ken as an asset. She didn't want them to keep the Land of Demons but she was clearly not in the mood to fight over it. It was a complex set of objectives that required keen negotiating. Fortunately, Shimiko had a few years of experience in that field as an ANBU.
"Pardon my bluntness Lord Mizukage but I don't think Kiri has the will to prosecute a man like Ken. Ken sent an entire ship's worth of slaves to this village. Men, women, and children packed like sardines into a ship and sent abroad to be bought like animals...." She let the words sink in for dramatic effect. "He wouldn't have done this unless he genuinely believed that there are people in your government that would accept such a heinous gift. I recognize you are not responsible for his sins just as we are not responsible for Léï. However, given your government's reluctance to deal with Ken, and based on the information we've gathered, we cannot risk the possibility that he escapes justice. My counter-offer is this: Allow us to try Ken. We will punish him harshly but cutting off his hands. However, he will be permitted to live and once we have punished him, we will turn him over to your village. Kirigakure may continue to occupy the Land of Demons during his trial and up until we deliver him. I must insist that you permit Kumogakure to station shinobi in the Land of Demons so as to observe your Nin and ensure that no other human rights violations occur. Sound fair?"
