In Konoha, the Uchiha Clan's One-Punch Man!

Nan Xi transmigrated to Konoha and became a member of the Uchiha clan, only to be judged a good-for-nothing who would never awaken the Sharingan.

In three years, it would be the night that filial son Itachi wiped out the clan!

Thinking all he could do was keep his head down and survive, he awakened Saitama's training method and began exercising, growing stronger without limit!

Fake ninja: Sneak attacks, flashy jutsu, high offense and low defense.

Real ninja: A humanoid beast, a body made holy, smashing everything to pieces!

Nine-Tails: Compared to Nan Xi, Madara is nothing! One left-footed kick from him and I'm done for!

Madara: The young man has no honor! Picking on an old man who's ninety. Is that right? No, it isn't!

As Nan Xi grew more and more invincible, the female characters began acting strange too.

Hinata: Nan Xi is so... so amazing! I'm going to melt~

Tsunade: His serious piston thrusts are too powerful! Slug, give me a push, I'm running out of strength~!

Mei Terumi: Nan Xi has such a fiery temper! Whenever I'm with him, I can't help using the Great Waterfall Technique at full power!
