This is the story of Madaki Uchiha, the eldest son of Kawaki and Sarada Uchiha and Kāmi Kakei. This story takes place 15 years after the final battle against the Ōtsutsuki, Jura, and the Shinju.
In this story, Kawaki and Sarada Uchiha had a child... in fact, 3 children... this desire to have so many children came from Kawaki as it reminded him of the time when he lived with Boruto and Himawari Uzumaki.
Madaki Uchiha is 12 years old... in his character, he is very proud like his father and very, very proud of his Uchiha blood. From a young age, he had knowledge of the entirety of the history and of each member of his cursed clan. His grandfather Sasuke Uchiha had told him everything, but that was not enough for him... knowing of Orochimaru's existence, he had the audacity to go and meet him and tell him in more detail about the history of his clan. Madaki was a very proud Uchiha... similar to Madara, so proud that it greatly surprised his mother and his grandfather... in fact, he inherited his pride from his father who also had that aspect, but he redirected his pride in the name of his Uchiha clan... Kawaki had officially taken Sarada's name after their union, in fact, Naruto was a big fan of this couple because he was somewhat the reason for it and he himself had created this bond between Sarada and Kawaki back when they were young.
In this story, the Uchiha are the dominant and highly respected family in the village. Sarada was the 8th Hokage, Kawaki was the head of the new brigade department, called the Power 1000 Brigade (composed of the most powerful ninjas in Konoha who don't hesitate to get their hands dirty when necessary), he was one rank above the ANBU now led by Inojin. Shikadai was Sarada's advisor, Sumire Kakei was the head of the scientific department, Himawari the new leader of the Hyuga clan, and they all also had children (except Himawari).
"Finish... it..." he gasped.
"Don't act brave. You're terrified. Is this truly the first time you've stared death in the face?" Boruto elected not to answer, but that was answer enough. "I won't kill you."
"W-why?" Boruto managed to get out. Ansei stood and started walking away. "Why?" Boruto called weakly, but a little louder.
Ansei stopped for a moment, bowing his head. "Because you can stop me..." and with that, he disappeared into the village.
After a heated argument with his father, Boruto decides that he and Himawari are better off not living in Konoha. Sarada decides to tag along in their doomed attempt to run away to make sure they don't get themselves killed. After only a day out of the village, Boruto realizes his mistake and decides to head back. Upon returning home, however, they find themselves in a village untouched by Pain's attack; a village with an Uchiha as Hokage and the Hyuuga Clan are threatening civil war at every turn; a village that is far more dangerous than their own.
In that village is another child named Ansei; who has been living as the Hyuuga's lap dog since his first birthday. Full of anger, Ansei is a force to be feared and respected... When Boruto meets his otherworldly sibling, it becomes a race to get his family home and away from this world that seems hellbent on getting rid of the children that shouldn't exist in it.
