3rd Person Pov

In the darkest part of the Void, a single entity was seen floating aimlessly without any active movements. He was unconscious for countless of millennia after the end of the lifespan of the universe. His friends, subordinates and loved ones was long gone, but he took all of their souls and kept it inside his imaginary space where he can awaken them again. They've been serving him for countless of years and that being felt pity seeing his subordinates work all of their life for him. So he told them to take a rest and let him handle everything else. Most of his subordinates refused to leave, but due to his promise that he will keep them inside, they all agreed to their masters wishes. After that day, that being went to an eternal slumber, leaving the world on its own natural destruction. During that time, new worlds, and universe was born, but no one knows about the great being who are once worshipped by all.

Now after a countless millennia of sleep, that great being was slowly showing movements. He's eyes are starting to show life and the one person who was always by his side, cannot hide her joy.

Rimuru Pov

{Master, You've finally woke up.}

The first thing I heard after opening my eyes was the voice of my partner that has been with me since the day I was reborn as a slime.

*{Ciel, Sorry for making you wait so long. It must be lonely.}

{No not at all. I'm with you all this time so it's not so lonely. But I'm glad that Master is finally awake now.}

Even when I apologized, Ciel seemed to be not bothered about leaving her for so long.

*{Okay even if you say so, I'll still apologize. Because of my selfishness that you have to went through with such loneliness.}

{Master should not feel sorry about it. I live in order to grant Master's wishes. I serve no purpose without Master.}

I felt happiness through her words that I quite longed for in such a long time. After my subordinates left me to rest within me, I went through a phase of grief which caused me to lose interest in things. I want to forget those feelings so I asked ciel to put me into eternal sleep until I no longer have those lingering feelings which she did without any complaints.

*{Thank you ciel, let's forget that now and move on. For now, mind telling me what have you been up to?}

{Okay Master. During your sleep I've watched thousands of worlds come and go and I've witnessed different events in the universe which was fascinating enough for me to analyze.}

I'm relieved that ciel was having fun even when I'm not here. It gave me a sense of calmness after hearing that.

*{I see. That's good for you ciel. So is there anything particular that we can enjoy right now? I want to enjoy life again.}

{If that's what Master wants. I found a world we can explore.}

'A world we can explore?, thats interesting.'

Excitement filled my mind. It was a long time since I went traveling through worlds with ciel. Might as well try it again.

*{That's interesting. But I want to feel human again, would that be possible?}

{Totally. Anything can happen if Master wishes for it. I'll prepare a body for you to reincarnate in a world similar to your previous one.}

A body huh.
