The Invincible System of Time Travel

The sinister otaku traveled through time and became Uzumaki Naruto, bringing with him the strongest system to create the strongest harem. Ahem~~ I said it wrong, create the strongest Hokage. A certain otaku: "Wait, let's see what this daily mission is. Well, it's very simple. Just kick the third Hokage's ass. Okay, I admit that you are trying to trick me. Can Naruto's ass be kicked? Even if kicked, can the ANBU let me go? God, someone will save me." A certain system: "I am God." A certain otaku: ".........." "You take it and I'll do it. Isn't it just a kick in the ass? What's the big deal? I'll still be a good man in at most eighteen years." This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
