Naruto: Help My Brother Kill Everyone Who Bullies Me, Okay?

My pairing is with Sasuke. I’m a miserable ninth-grader rushing to morning study when I unexpectedly get transported to the world of Hokage. Sure, I have a golden finger, but I don’t have enough chakra! What if I die? I don’t even know any ninjutsu! I just watch Hokage, I don’t fight! Is this what I get for playing Honor of Kings every day? There isn’t even a System here. Oh, right, I think I have an older brother who’s an extreme younger-brother fanatic. What!? I’m an Uchiha?! Don’t bring that unavoidable separation from the Uchiha Clan ten years ago into this! I’m going back to the clan, no questions asked. I’ll just save the people I can’t bear to see die every day. Haha, I think I’m about to die. Why do these one or two jutsu use up so much chakra? Why does Sasuke keep staring at my healing skill? I’m coming, Brother Sasuke! Help me kill Danzo, and those two advisors too. The three of them have scared me plenty of times behind my back.
