Living in Konoha: I Can Collect the Power of Tailed Beasts

When I started traveling through the world of Naruto, I thought I was a veritable loser and could only survive until the end. However, I unexpectedly awakened the power of the system. As long as I get the friendship of the boy who sealed the tailed beast, I can upgrade the system... Otsutsuki Kaguya: "This child actually has the blood of my Otsutsuki clan!?" Hatake Kakashi: "Ahem, I don't want to admit it, but you are indeed more handsome than me." Uzumaki Naruto: "This is my brother! If you touch him, you will get in trouble with me!" Hinata Hinata: "Brother Nilin, I..." Uchiha Itachi: "We, the Uchiha clan, owe you a favor." This novel and its characters are purely fictitious.
