Sebastian Michaelis

You give up your future, lose your dream, are stained with despair… yet at the same time, you shake off you past, fight reality, and never lose your nobility.

— That's right... I've nothing left. I've lost everything...
— Lost? What a funny self-pitying thought. You didn't lose them. Didn't you have nothing from the very beginning?

Always skillfully manipulate your pieces, that’s how you survive. Use me and madam red, any piece within your reach. Even if the bodies of your pawns pile up in front of your throne. Because if the king falls – this game is over.

It is quite unpleasant to be stepped upon. Doing the stepping, however, feels quite good.

Hatred and sadness belong to you. Turn your feelings into power. It's fine that you can keep moving forward.

Also, I doubt a bonding experience without pain would be a fruitful one.

— Wanting to be loved, for that sole obstinate reason, people can even go this far.
— Honestly, how meaningless.
— For something called love, which has neither meaning nor form. Laughable, isn’t it?

— He could be a spy, Agni.
— No. I'm just a deer...

The image reflected in a picture is but an illusion. However, even if it is an illusion, wishing to hold onto it is one of the hollow dreams humans have.

Nationality does not matter. Wherever and whenever you are, there are always similarities. Between humans, that is.

Humans are vulnerable to temptation. When they are forced to stand on the hellish precipice of despair, they will unfailingly take any route out of it that appears before them, no matter what kind of web it tangles them in, no matter what kind of person they are.

Grell: — Both of you will go to Heaven together!
Sebastian: — Heaven? That has no hold over me.

— Where am I?
— Do you want to know?
— I’m asking because I want to know.

I have no idea what you’re talking about, but I tie cherry stalks with my tongue.

Unlike demons, you’re base, you harbor a complicated malice, you lie… You struggle desperately, knocking down others in your way… You steal and are stolen from, you make endless excuses… And still you strive to get over the hill and far away. I suppose that’s why humans are so interesting.

He was tied by the superficial rules, and he lost by not using his pieces to their maximum potential. He's a fool.
