...I am the son of the great King of Knights.
...I am the arrogant Treacherous Knight.
I am both, and both are myself.
But once I put this helmet on, I am neither of them.
I simply become a living being that you can see everywhere, worthlessly struggling for the right to live.
So just like those that draw their last breath, I guess I will perish like they did.
That's why I want to know, before I leave this world.
...Just who the hell was I?
Fan Translation:
――I am the son of the great King of Knights.
――I am the arrogant Knight of Treachery.
I am both, and both are myself.
However when I wear this helmet, I am neither of those
I can only think that I'm just like any other living being
One that you can find anywhere, worthlessly and frantically trying to stay alive
So just like they breathed their last breath
I guess that I will surely perish like they did
That's why before I meet my last moments, I want to know.
