Naruto: Sasuke Is My Brother, He Changed His Life by Acting as a Lunatic.

In a world line destined to have a parallel universe, Uchiha Sasuke is a good brother, and he will also have a younger brother, Magic Pill... [Congratulations to the host for turning six years old, the strongest Uchiha development system has been launched! [Mission: The Lord's bravery is unparalleled throughout the ages! This system instantly gives the host three magatama sharingan eyes, which last for three days and three nights and will never dissipate! With the power of Akira Uchiha! "The God-Man System, my whole family is still watching? How should I explain it to them!" [Mission: The domination of the ninja world begins with your feet! How can one govern the world if one group is not unified? This system gives the host the most powerful fireball technique in the universe. I hope the host will show his ambition to swallow the world in front of his teachers and classmates and show his sharpness! "Are you asking me, a naturally evil Uchiha brat, to speak of unifying the ninja world in front of the Sandaime Hokage?" [Mission: The battle between the heir apparent has always been like this! Defeat your incompetent brother, Uchiha Sasuke, and prove that you are the strongest Uchiha in history! "I finally came to my comfort zone. My stupid brother, there is nothing I can do for my brother's happiness. Even if the system doesn't give me anything, it doesn't matter. Just sacrifice yourself here with honor!" Uchiha Cube, the design prototype of Uchiha Sasuke, suddenly looked solemn and looked at the 'supporter behind Mirai Kage'. "What happens in the future will be discussed in the future! I just want to touch my stupid brother's head now." Words are made secret, things are revealed! Let's see how the Uchiha Rubik's Cube copes with system convulsions while pretending to be crazy and stupid in front of everyone, suppressing his growth.
