Naruto, Be My Daughter, Otsutsuki Kaguya

An ordinary young man from the modern world transmigrated to the perilous ninja world after an accident.

In a world where bloodlines and birth mattered most, lacking the bloodline of the Otsutsuki Clan meant it was almost impossible to reach the Six Paths level.

Without the power of a tailed beast, a kekkei genkai, giant eyes, or Sage Mode, reaching the Super Kage level, or even the Kage level, was nearly impossible.

In this perilous ninja world, Yagyu Ichi, who came from an ordinary background, had nearly fallen into despair. Fortunately, at the critical moment, his golden finger, the Heavens-Dominating Dad System, finally arrived.

And so the ninja world's style began to change dramatically. “Become my daughter, Hinata.”

“Become my daughter, Princess Tsunade.”

“Become my daughter, Princess Kaguya.”

“Clan Leader Hiashi, Hinata may be your daughter, but she's also my daughter. So I hope you'll speak politely to her from now on. Otherwise, I'll be very unhappy.”

Inside the Land of Fire's biggest casino, Yagyu Ichi gently patted Tsunade on the head.

“You only lost a hundred million ryo! That's pocket change. Don't look so down. Anyone who sees you might think we can't handle losing. Here's another billion ryo. Go ahead and lose as much as you like.”

Naruto, wielding Six Paths power, Sasuke, wielder of the Rinnegan, and Otsutsuki Kaguya faced off in a final battle. An overwhelmingly powerful aura descended, instantly enveloping the heavens and earth. The entire ninja world felt despair and oppression.

“Who dares lay a hand on my daughters? You two think you can?” Yagyu Ichi's overwhelming aura immediately bore down on Naruto and Sasuke. Even though both now wielded Six Paths power, they felt like weeds in a storm, powerless to resist.
