You humans are always talking about hearts. It's as if you have them in your hand. But my eye sees everything. Nothing can escape it. What it doesn't see doesn't exist. That's how I've always fought. That's how I've always lived. What is a heart? If I rip open your chest, will I find it there? If I crack open your skull, will I find it there?

There is sufficient probability the world will be destroyed
Your weak souls will squirm
For the time being I will kill a few souls
Everything will be stained with crimson -- Are you scared?

For the fools who have the nerve to investigate
I will leave no record of their interference

When the dust scatters there will be destruction
At any moment I can sever your breath
Although you stubbornly keep breathing
Ah, this must be the trivial world
I'm not sure what will become of it
Well then, with this hand, crush the world down

You're always causing problems. How could I entrust you with a so called heart?
For a Fraccion I do agree that we have some sort of a different bond.
Green thing? I believe you're speaking about Myouri, am I correct?
No. I will not play with you, little girl. I have more important things to do.
You decide to cowar before me in forgiveness. Stop wasting your breath.
Smile? No need for such a thing.
You need to pay more attention, woman.
