In Hokage, Tsunade Is My Sister!

A modern ki warrior travels through the world of Naruto and becomes Tsunade's younger brother, Nawaki. "I'll take care of myself now that I've come, not to mention having such a beautiful sister! From now on, I'll call her... Senju Nasuki!" Immediately afterwards, he discovered... "Wind, thunder, water, fire and earth? Isn't it metal, wood, water, fire and earth?" Shengshu discovered that Wood Escape had become a basic escape technique in his hands. "Golden Escape?" Shengshu looked at the metal products suspended around his body and murmured: "So it's called Magnetic Escape in this world!" "Natural energy? Isn't it spiritual energy?" Roe Tree discovered that he could absorb natural energy into his body at will, and he didn't have to worry about petrification. … The Second Ninja War broke out, and Naoki joined the battle as a genin, and became the "strongest genin" in one battle!
