Chapter 0

"I am no ordinary "Sans" you see.

My name is Forbidden.

And this name is my whole existence to the different world that I once came from.

I should start from the very beginning; where my life changed."

For countless times that the human did a genocide run, they never killed Sans. Why even though they killed everyone else in the Underground? The answer is much different than expained.

They are not DETERMINED enough.

But what happens when change starts to happen in Sans' world. What will happen to the skeleton?

What happens to his universe?
