The Three Little Ones Raised by Sukuna

[Two souls sharing one body after transmigrating twice + sailing-with-the-crew story]

I was the King of Curses, but an otherworldly spirit who wanted to change me for the better tricked me into the pirate world.

Looking at Luffy, Ace, and Sabo before me, I smiled.

Fine. You want to raise kids, do you?

He taught them protection and bonds. I taught them plunder and destruction.

I set sail with Luffy, and when I saw him sometimes acting differently from the original story, I smiled. Soon, I'll kill you! You're a spirit, so get back where you belong!

Until that familiar cursed energy appeared…

No wonder a spirit could go this far. So you were involved too!

Later on, the three little ones might travel through the original story.
