Naruto: Kakashi's Brother, Starting with the Sparkling Fruit

[Naruto fanfic + system + devil fruit + fun person + invincible cool article + multiple female protagonists + not feeling aggrieved] After traveling through time and space as Kakashi's twin brother, Sora Hatake faces the beginning of hell where his father is about to commit suicide and his brother has turned dark in the future. However, he is still a chakra insulator and is ridiculed by the whole village. Fortunately, I awakened the "Ultimate Revitalizing Demon System" and started integrating [Sparkling Fruit] without any side effects! Don't know how to form seals? No chakra? I'm sorry, I'm going to physically transcend directly! As a result, Konoha's painting style completely collapsed. Anko: "Hatake Sora, you are a gangster, moving at the speed of light just to lift my skirt?" Danzo: "Stop him quickly! He used strong light to treat the root base as a disco. I'm blind!" Madara: "Speed is weight? Damn it, he kicked my perfect Susan to pieces!" Facing the collapse of everyone, Kong wore brown sunglasses and put his hands in his pockets: "It's so scary~ Everyone, have you ever been kicked at the speed of light?" This is a new legend of Konoha where there is no bitterness or deep hatred, only extreme joy and dimensionality reduction. Kakashi: "My brother is good at everything, but he is too coquettish."
