Reborn in the Naruto World as Uzumaki Menma

[No System + female characters + naturally born double pupils + doppelgangers with Mangekyo Sharingan + somewhat dark + rogue ninja + building a faction]

(Hinata, Fuka Koyuki, Shion, Guren, Karin... These are the female characters who will get the most attention, but not all of them will have romantic storylines.)

Reincarnated as Uzumaki Menma, Naruto's twin brother, he had died of heart disease in his previous life, and illness continued to haunt him in this one. Convinced that his fate was a wretched one, Uzumaki Menma resolved to live as he pleased, take control of his own destiny, and attain immortality. He had to live forever!

Corrupt nobles, incompetent lords, people suffering in misery, and the shinobi village system that brought nothing but war and pain... The shinobi world needed a revolution. This revolution was destined to be drenched in blood and strewn with corpses. It had to be led by Heaven, and I had to be the one to pass judgment.

I walk in darkness, my heart turned toward the light. In this sinful world without justice, judgment belongs to the Lord!!
