After the incident at the feudel lord's palace Sonkei and his branch have become worried about what will happen now. But strangely the feudel lord did not take immidiate action to execute the Hyuuga. Instead letters were exchanged between the feudel lord and Sonkei upon the matter as neither of them had the time to meet.
Dear Hokage,
This letter was sent by a the feudel lord's advisor but written in his words exactly. Not long ago the feudel lord awoke to find a shinobi of the Leaf Village within his room along with the bloody corpse of one of the palace gaurds. This shinobi had purely white eyes, which leads us to believe they were a part of one of the many shinobi clans of your village. As we recall this clan is known as the Hyuuga. Before we decide upon their fate we wish to know your side of the story.
Dear Advisor,
I will not deny that what you say is true a shinobi of the Hyuuga clan was in fact dispatched the palace but I must bring to attention that I myself am of this clan. Unfortunately I have no proof of our innocence to give to you so I cannot prevent punishment from being passed upon us. However I will tell you that the entire Hyuuga clan is not at fault for this incident. The Hyuuga clan is divided into individual branch's the main, cadet, and the 3rd branch. Responsibility of the actions of each branch falls upon the branch leaders and not the clan leader. This assassination attempt was carried out by a hyuuga of the third branch. The current branch leader is in fact myself so if possible do not have punishment pass upon the entire clan but upon myself and my branch.
Sincerely,
Sonkei Hyuuga
For a week there was no reply to Sonkei's letter. But after that week a letter in response at last came.
Dear Sonkei Hyuuga,
We have considered what you told us. And have come to a decision. This third branch will be executed. And you will step down as hokage. You will not be executed with your branch but you will not be allowed to continue as a shinobi. The execution will commence in two days.
