Futsunomitama activated the ocular power of both eyes at once, allowing the user to bestow a soul directly upon any object in their gaze!
Of course, it only worked on objects without souls!
Of the five Six Paths Tools, the Amber Purifying Pot was the largest. It worked by calling out a target's name: if they answered, they would be sucked inside; if they went too long without answering, they would also be sucked inside. Its function was the simplest and most brutally direct!
Naruto focused both eyes on it!
Futsunomitama!
Hum!
The black diamond pattern on the front of the Amber Purifying Pot turned into a face. The strokes of the character "dust" within it became eyes, a nose, and a mouth, while the two protrusions on its lid became ears. [This description is a little abstract; look up a picture of the Amber Purifying Pot and it will become clear.]
The Amber Purifying Pot blinked a few times, then called affectionately to Naruto, "Daddyyyyy!"
"This..."
All the Hokage were astonished!
Tobirama was the first to spot the overlooked issue. "Naruto, what criteria do you use when giving an object a soul?"
Naruto asked, "What criteria? I don't quite understand."
Tobirama said, "Too abstract? Let me put it another way. Where does the soul's 'personality template' come from? You?"
Now Naruto understood. Rubbing his chin, he did his best to explain. "Hmm, souls have a 'spectrum' too, which only Futsunomitama can see. That spectrum determines a soul's traits, like... personality and talents, I guess."
"Also, Futsunomitama has a 'palette.' At the instant I use the dōjutsu to give an object a soul, I color that soul based on my own impressions, determining its spectrum. That's roughly how it works. I can't really explain it in any more detail..."
