I transmigrated into the Naruto world and became a member of the Hyuga clan. At eight, I awakened the Tenseigan and rose to the rank of elite Jonin. At nine, I single-handedly completed twenty extremely difficult S-rank missions, earning a place as a candidate for Fifth Hokage, my genius resounding throughout the ninja world. Then... I gave up. I had no interest in conquering the world, nor in causing trouble everywhere; I just wanted a peaceful, laid-back life. A ninja doesn't need to risk their life everywhere; completing missions and picking up girls is the true path. But I never expected this! I've already awakened the Tenseigan, and you're telling me there's a system? A mentor-disciple system, making me take over Team 7? Rewards for educating Team 7? I just wanted to give up, but the system wants to make me invincible! "Hinata, I'll teach you the Gentle Fist of the Night!" "Cang...Cang Yue-nii...?"
