Yu woke up in a private hospital in the northern outskirts of Dongshan City.
The shrapnel had been removed from his body, but the injury to his lungs meant he still had to use a ventilator.
The mysterious woman sat cross-legged on a chair beside his hospital bed. "Heh heh, you're awake."
Yu said, "You're... Tornado, right?"
The mysterious woman said, "Tornado? Heh, I'm Sana. In this world, my name is 'Ye Fei,' and I'm a housewife and novelist!"
So that was it!
"Which space-time's Sana are you?"
As far as Yu could tell, this could not be the Sana from the Seventh Space-Time. That Sana's soul had transferred into her daughter Little Tornado through reincarnation, so she could not exist in two worlds at once.
Ye Fei slowly revealed an astonishing truth. "Heh heh, I belong to no particular space-time, yet I belong to every space-time. Those who awaken the Baya Wake-no-Mikoto Shikigami don't possess multiversal unicity, but multiversal synchrony. My mind is connected to every version of me across all space-times. Together, we make up the existence that is me!"
So that was how it worked... In a sense, multiversal synchrony was even rarer than multiversal unicity!
Yu asked, "Was Baya Wake-no-Mikoto also what allowed you to cross into this world?"
Sana said, "Heh heh, that's right. Baya Wake-no-Mikoto is a Shikigami that can roam freely, unbound by space-time. But I didn't 'cross over' the way you did. Baya Wake-no-Mikoto creates a custom-made incarnation for you based on the characteristics of the world!"
Yu said, "It can even do that...? Root King seems determined to transcend the Naruto space-time and reach the real world, but Baya Wake-no-Mikoto could easily grant his wish, couldn't it? Has he never thought of stealing that Shikigami from you?"
Sana said, "Heh heh...
