This is my version of Kyoko and her thinking of what she will do to Sho.

Day and night,

I tended to your well being.

You tossed me away.

Now it is my time.

Revenge is imminent.

I will have the upper hand.

I will crush your soul,

As you did mine.

I will crush your heart,

Into nothingness.

You will be missing,

Something important.

The same you did to me,

I will do to you.

I will show no mercy.

I will show no shame.

This is what I am now.

A devil with an angel's face.

My happiness faded,

Before my eyes.

My childhood robbed,

From me.

With no right,

To even think for myself.

I selflessly took care of you.

It was enough for me.

Apparently not for you.

You discarded me.

No afterthoughts.

Or regrets.

I will crush you!

No matter what happens!
