She was asked to see the Hokage first thing in the morning.
"Hinata we have a situation, as I told you before I was to go to the capital of the Land of Fire to sign a new contact with them in two months. I have just received word that there has been some kind of situation there, if I understand correctly a grandson and heir of one of the most wealthy citizens was nearly kidnapped and they ask for permanent protection. I can't go there personally, so Hinata this is your first mission in a long time, go there assess the situation and recommend a team to fulfill this duty. You are to leave in one hour. Sakura will take over your shift in the hospital." Tsuande demanded.
"Yes I will leave shortly." Hinata replied quietly "But why have you chosen me to do this?"
"You are well prepared by your father for doing these kind of things, and you are the only ninja with the right rank to do it. I won't send some stupid genin to deal with one of our most important clients." Came a swift response. " Your father had already approved. There is no risk in this mission, it's mainly diplomatic so you needn't worry too much."
"I am not worried it's just that I don't want to leave Hizashi for so long, maybe someone else could go there…" she suggested.
"No! You spend too much time at home anyway. It's time you came back to life, and I need help with all this diplomatic shit. You are the best person for the job, so don't make me repeat myself and get going! Here are the details" demanded Tsunade.
Hinata left Konoha as ordered and headed off alone towards the capital of the Land of Fire.
She began her duties with visiting the Feudal Lord who had called for Konoha's assistance. She was given a report on the situation which she promised to looked into afterwards. The negotiations were long, and the Feudal Lord had many demands but Hinata's instructions were precise and clear, and she signed the contract according to the guidelines of Tsunade. Konoha was to assist the Feudal Lord in any situation, and no permanent troops were needed, the financial terms were very good for Konoha, and the Feudal Lord felt safe knowing that a strong shinobi organization will always be ready to help him.
Later she installed herself in a nice hotel and began to read the report she was given. So there was already one attempt of kidnapping the child and it was stopped by the guards. That was good it meant that this Lord Kinto had some good guards around. She decided that she would visit this lord the next day and take a close look at the household and decide that kind of contract to propose. Tsuande did not give her many details about this deal so Hinata felt a bit scared.
The next day she put on her elegant kimono with the symbol of Konoha embodied on her chest and went to Kinto estate. She was guided by the servants to the office of the Landlord and she gently knocked on the door. She heard someone walk up to open it and soon she was looking into eyes identical as hers. She managed to whisper "Nissan" just before she did what she was best at, she simply fainted.
