Mushoku No Sonzai 無色の存在 (Colorless Existence)

I open my eyes up slowly. My body felt very relaxed and smooth. As I slowly came to my senses, I noticed there was nothing around me. Nothing. Just a vast, white emptiness, shrouded in complete silence. I sit myself up.

What's going on? Just a moment ago, I was...

...

I don't remember. I rub my eyes. Why does it feel...as if I have been asleep for several years? I look around, hoping for any clues. But it was useless. Suddenly, I hear a young boy's voice gently reaching me.

"That's right, Nobuyuki Susumu. It was all a dream. A really long, scary dream."

I don't see anyone. The voice felt familiar. Frighteningly familiar..

"What do you mean?" I cautiously asked.

He chuckles, although I still couldn't see anyone. All I could sense was a chill driving up my spine.

"Don't worry, Susumu. In due time, you will understand the meaning of your dream. But, now is not that time. After all...We have so little time to spare anymore."

The white space around me begins to fade out slowly to black, turning to complete darkness. I feel myself suddenly float down slowly, unable to move. What's going on? What does he mean by "dream"? Who does that voice belong to? The temperature drops dramatically. I feel my body freezing up instantly, as if I was suddenly thrown into a giant freezer.

"You had a very, very long dream, Susumu", the voice suddenly said. "One day, you will understand the meaning of your dream. When that time inevitably comes, you must decide for yourself the fate which you forge for yourself, the fate of existence as you know it. Once you understand these words of mine someday..."

I can't speak. I can't move a single muscle. I felt lighter than air, yet weaker than a rag all the same. All I could do was listen..

"..stop..me.."

Stop you? But, who exactly are you? What do you mean by this or that about fate? I felt my own vision fade to complete darkness as my body began to freeze up more. It's cold. Devastatingly cold. I can't feel my own body anymore. I still have so many questions for this mysterious voice, and yet the words won't come out..

I'm waking up from a really long dream? This doesn't make sense. Nothing that voice said makes any sense at all. Nothing makes sense anymore..

I feel my freezing body slowly sink down into an empty abyss, a seemingly endless sea of nothingness swallowing me deeper...

A really long dream...of several years. What does any of this mean?
