Sign In: I Became Hokage When I Was Six Years Old

When the fifteen-year-old Chuuni's soul traveled into Naruto's body, he also got a sign-in system. As long as he signed in, he could become stronger. From then on, there was a new legend in the ninja world! "Ding! Tsunade's boudoir sign-in is successful, and she will be rewarded with ten times the physical strength and super self-healing ability!" "Ding! Uchiha Madara's coffin board has been signed in successfully, and the same Mangekyō Sharingan will be rewarded!" "Ding! The Miaomu Mountain sign-in is successful, and the Miaomu Mountain Immortal Technique will be rewarded!" … One year later: "Tailed beast? Is it very strong? My yard is short of a janitor. The nine of you will compete for the job." "Uchiha Madara? It's just the dust of the old times. Do you still want to dance?" "The Otsutsuki clan? Invading the earth? See if I don't scatter your ashes!" "If you can crush someone with force, who will use your words to convince others with reason?" "Only I can create a new world!" "If you can't pretend, force me to pretend. I'll kill those who you can't kill. I'm blessed with good luck, God's chosen one. This is me, Uzumaki Naruto!" "Become Hokage? No! I want to be the god of this world!" "The sky is big and the earth is big, I am the biggest, I am your sky!"
