Uchiha Sasuke was reborn, and he changed the fate of the Uchiha genocide. But when he wanted to enter Uzumaki Naruto's life little by little like boiling a frog in warm water, he discovered that there was a girl beside Uzumaki Naruto who had not appeared in his previous life. And that girl doted on Uzumaki Naruto very much, and guarded him against other boys just like she guarded against wolves (even though he was indeed a wolf).
Original character: Uzumaki (Chiba) Liyue
Identity: She is Uzumaki Naruto's (different surname) sister, and is also a small part of the world consciousness. This world consciousness has obtained some memories of the parallel world consciousness, and learned that her son (the pillar of the world) lived a miserable life. She really wanted to pamper her children and worked hard to prevent the tragedy from happening. When Otsutsuki Kaguya sealed the authority of world consciousness, she separated a small part of her consciousness and became Chiba Liyue.
Ability: Possess the five attributes of chakra: fire, wood, water, wind and thunder; possess 1/4 of the whirlpool bloodline and know most of the whirlpool sealing techniques; at the same time, it can resurrect the dead, but every time an important person is resurrected, he will enter a brief coma or period of weakness. This process can be divided into several days or hours, mainly because of the protective measures taken to prevent the Otsutsuki clan from discovering it.
Time: When Uzumaki Naruto was two years old, she came to Uzumaki Naruto and became Uzumaki Naruto's guardian for some reasons (Private setting: World Consciousness used some way to make the people of Konoha think she is the adopted daughter of Golden Flash.) She is four years older than Naruto. Her hair color is purple and her eye color is blue.
Intention: Self-reliance and self-reliance
