The secret dungeon was kept for resolving matters that were too sensitive to handle in public. Clan leaders who had gone rogue or Uchiha guilty of particularly embarrassing crimes could be tried and executed without risking damage to the reputation of the clan. The dungeon-courtroom was so deep below the earth that nary a sound could escape from the structure. All Elders who were called to try their brethren in darkness maintained a vow of secrecy. When Nyguyen sent Satomi to capture Akihiro, he immediately began preparations for the trial. He had notified some of the Elders and told them to convene here. He had compiled all the information on Akihiro's crimes and handed them to each of them in dossier form. The dossiers contained the truth, the whole truth, and nothing but the truth. Or at least Nyguyen's version of it.
Akihiro had attacked Moonsire without Nyguyen's permission and although he had done so with good intentions, he had acted without mercy. Nyguyen had also included the fact that Ikomiki had killed a young Senju named Shinsui during the Chuunin Exams. Akihiro then covered up the death and implanted the Senju's liver into Ikomiki. He even included the possibility that Mockingbird had ties to the Society through Menza and Ikomiki. Ordinarily, it would be difficult to convince the Elders to take action against their Clan Leader even if he was an insolent young brat. However, Nyguyen had explained the nature of the geopolitical situation to them. Kiri knew about all of this and after overthrowing Aki's compatriot, they were now ready to turn a new leaf. If Konoha did not deal with Akihiro, then they'd break the alliance and join up with Kumo. The two nations would then be strong enough to crush Konoha. They'd take Akihiro and all of the secrets that his eyes possessed. Worse yet, Kiri might leak the news about the Senju boy. Between Chikamatsu and this Shinsui, the Uchiha might face a united revolt against their rule. Civil war within and invasion without would mark the end of their family and all to protect a clan leader that was more absent than he was present?
"Preposterous"
"Absolutely not"
"What must be done, will be done"
"Bloody well then let's get on with it"
The Hokage was not blameless in this but Nyg had conveniently left out the part where Akihiro had confessed to him. He couldn't put himself or his own kin in jeopardy. It would be Aki, his, and Sato's little secret. Nyguyen stood in the center of the dungeon-court and he looked towards the door where Satomi and the prisoners were to enter. He had set the ink materials on a table off to the side. The Kaifeng Mercenary should have been here by now and the mystery guard's lateness was irking him. The Elders were sitting in a spread out jury box that wrapped around the center floor. A symbolic arrangement to show that the oldest and wisest of the Uchiha would analyze the accused from every angle. They'd scrutinize their subject and strip the lies from the truth. When they were done, a verdict would be handed down and with it, punishment.
Nyguyen held his tanto in high right hand and did his best to appear impartial. His father was sitting in his wheelchair to his right. The old man was named Katahshi and he had always wanted his son to be a warrior. Instead, he got a mediocre bookworm. He had never failed to express his disappointment on this account but with Nyguyen's sudden rise to power he found himself smirking more than frowning nowadays.

"Finally getting some weight to those balls, hm boy?"
".....Nothing like this has ever been done in history before Father, please let's not do this here"
"Oh right, your still Mr. History Buff. You and your worthless books. Why can't you be more like Satomi? You think he got to being as strong as he did with his nose in some textbook?"
Nyguyen tried to ignore his father. Usually the man showed him more respect when there were other Uchiha around, but the events that had transpired put the elder in a bad mood. Nyguyen's papa didn't like Akihiro but he liked him a hell of a lot more than he did some nameless Senju, Damien Darhk, and a bunch of nobody civilians. Akihiro shared his last name and Katahshi being as old as he was cared more about that then he did the stability of the Hidden Leaf. Unfortunately, he was smart enough to know that what his son had told him was at least partially true. If the Uchiha tried to protect him then it might cost them everything. Swallowing this was easier than the alternative. It didn't make the old man any less pissed off and he decided he'd take it out on a familiar target.
"That's the problem with you eggheads...you, Aki, the lot of you. You think you know everything. 'nEvEr bEeN dOnE in hIstOrY bEfoRe' pah! You just never read about it. Plenty of things were done down in this dungeon. Things we shielded your generation from. Let's see if you have the stomach to carry on the tradition. How about it sonny boy? Do yo-"
Nyguyen didn't speak but he did turn from the door and look at his father. The Hokage's Sharingan was active and there was a look in his eye that had never been there in all the years that his father had raised him. Juniper had always had the killer instinct that Nyguyen lacked and he had often teased his son about it. But for the first time, Katahshi could see it. The sign was there plain as day. The thing that some might ignorantly call "the Curse of Hatred." Katahshi had more to say but that one look shut him up. He had known his son wasn't telling them everything. He could tell the moment Nyg had pitched the situation to them. Father's intuition and all that. When he was a Jounin, Nyguyen was just playing the part, but now that he was Kage he had been forced to do things that made him be the part. Katahshi held his tongue but couldn't resist grinning. He was finally getting the son that he had always wanted.
More smirking than frowning indeed.
