Prologue
My spikey red hair bounced up and down as I walked the seemingly endless corridors of the once home of the Nobodies, the Castle That Never Was. The entire castle seemed abandoned. A cold wind traveled the hallways, and each footstep echoed off of the walls. I had visited my old room. Nothing was there, really. I hadn't seen it since I went rogue from the Organization.
I walked out of my old bedroom and went straight for Roxas's room. Roxas. My only friend in the world. I should've been there to bring him back. And now he was gone, away from my grasp forever. Why must he be away from me? I was my own person at last…all we had talked about together was regaining our hearts after creating the great Kingdom Hearts. Or perhaps I was only saying things like that to humor him.
In my hand I clutched a few sheets of paper I had found within the Usual Spot in Twilight Town. They looked to be in Roxas's handwriting. If he wrote journals after he lost his memory, then surely he kept a journal himself over here in the Castle. Didn't Isa…erm, I mean, Saix, give him a diary to write in?
And sure enough, after pulling open one of his dressers, I had found an old looking book bound in old brown leather. I opened the book, and sure enough, the first page had Roxas's handwriting on it. I put the pages I had in my hand in between the last page and the back cover, so I could read Roxas's diary and journal together.
I opened it back to its first page, and began to read, hearing Roxas's voice in my mind as I read silently to myself.
