Naruto from Another World: I Am a Legend

"You have martial arts, you have magic, you have summons, you have secret techniques." But I'm not afraid of you, martial arts? What kind of magic is it to open up the eight gates and beat you at will? NO! My ninjutsu scares me even just looking at it. Call? Hehe, the nine tails are too strong, let's take the first one first. Secret method? Should I use the Sharingan or the Samsara Eye or should I use the Corpse Vein? This novel and its characters are purely fictitious.
