How many years?

"What?"

Kairen thought he heard those words wrong.

"I said, the day you are talking about is the day I came to this world."

But what he heard were the same things. 

"We came here on the same day?"

Then why didn't they go to the same place? No wait, did his brother also have an Aaron 1 like he had a Kairen 1?

"No. That's impossible."

Aaron shook his head.

"Why?"

"Because I didn't leave Earth on the same day as you. I don't have much information about how time goes in this world and how different it is from the time of Earth, but even if there is a huge difference, I still don't think that it's possible for me to come to this world at the same and time as you, who was transformed much sooner than me."

'Time passes differently here and on Earth?'
