Naruto: Naruto's Sister in the Parallel World

In another parallel world, the ninja world is still in an unstable era. Konoha, which was attacked by the Kyuubi, was severely damaged. The Fourth Hokage and his wife both died, leaving only a baby with the Kyuubi sealed, named Uzumaki Naruto. However, the prejudice of the villagers made the descendant of the hero spend six full years in loneliness and malicious eyes. He was troubled and confused all the time: Why am I the only one without a father and mother? Why am I the only one without a family? Until one day, a girl who looked like a little tomato stood in front of him, raised her dusty face, and shouted crisply: "Brother." When she was young, she was a girl of unknown origins who lived in war. She lives with a wandering old beggar, whom she regards as her only relative and bond in the world. She had seen bloody fighting and thought the world was one of constant war and sacrifice, constant loss and death. She was deeply afraid and disgusted and ran away from it all. Until one day, death came again, and a fateful reunion brought her the most important person in her life, and she also had a real name, and her name was Uzumaki Kasumi. What was the truth back then? What is the fate of the two brothers and the ninja world? Let this novel tell you all the nonsense.
