NO KEKKEI GENKAI/NO SHARINGAN Passing through Naruto, he awaited for a system or Kekkei Genkai that never came. So he decided to invent himself a cheat! A madman wielding a knife was born in the ninja world! “Why are these petals so sharp?” Madara looked solemn staring at him. “Did a knife just cut off the moon?” Black Zetsu asked in confusion to his clone. “Come on, stop talking, let's fight.” One person, one sword, is enough to take on the world! ........................ MC is a Sword user, will also use Ninjutsu, mostly Lightning release. PS: this is Harem, so for the non-harem enjoyers, this may not be the fic for you.
