He saved me, and he disappeared, just like his parents back then, without any news.
"Amu, he disappeared. We are the only ones in the world who remember his existence."
"Are you so sure that there is another world, not some other country or region that we don't know about?"
"Because he disappeared right in front of my eyes, and I watched helplessly as he disappeared!"
I am certain that none of this is my imagination, even if it subverts my imagination, but there are other worlds in this world, beyond the knowledge of all of us.
"Amu, believe me, my parents must be there too."
He's there and I'm going to find him.
"You are crazy. You don't know how to find him or find that mysterious world. You don't know anything about it!"
There must be some trace to follow.
"... I finally see you again."
Don't forget me.
