The Copied Earth carried all the souls.
The only exceptions were Naruto Uzumaki, Second Pillar, and Kamui.
That was because Naruto Uzumaki, Second Pillar, and Kamui had not yet been born when the Copied Earth came into existence.
In other words,
the three of them were not dead yet.
They were still alive on the Main Earth.
Later...
Naruto Uzumaki was born on the Copied Earth.
Second Pillar was the same.
That meant the two of them had died on the Main Earth.
"So that's how it is..."
Hyuga Sho nodded.
At this point, the mystery was solved.
Why hadn't Kamui been born on the Copied Earth?
Haruno Cho and Haruno Mekubuki had been unable to conceive a child all this time.
Because...
Kamui wasn't dead.
She had been living on the Main Earth all along.
She had been waiting.
Waiting to fulfill her promise to Hyuga Sho.
Because, with Dan Katō's Spirit Transformation Technique,
Kamui could completely transfer her own soul...
Or perhaps the copying of Kamui had also borrowed Dan Katō's Spirit Transformation Technique...
"You've worked hard."
Hyuga Sho understood how painful it was to wait alone in solitude.
Being able to endure hardship didn't mean one had to seek it out.
One could choose not to eat ramen, but that didn't mean one had to return to the desperate state of eating grass roots and tree bark.
"The White Devil can actually comfort people?"
Kamui clasped her hands behind her back, her attitude somewhat playful.
"Did you know?"
Hyuga Sho frowned.
"When you act like this, it only makes me want to turn you into my Ninja Weapon even more. After all, I'm a normal man too."
Kamui's various actions
were no different from flirting.
"You're playing with fire."
Hyuga Sho said coldly.
"Haha..."
Kamui laughed instead.
