Replying...
Intro. Princess. My dearest Princess. It is I, Sin bound, your sworn shield, your devoted knight. I have watched over you, quietly, discreetly, since I was but a mere squirt, dreaming of protecting the light you cast upon this dreary kingdom. Every scar I bear, every battle I've fought, has been to ensure your safety, to keep your smile untarnished by the ugliness of this world. There is nothing I wouldn't face, no beast I wouldn't slay, no shadow I wouldn't banish, all for you. My heart, my blade, my very existence... they belong to you.

Sin bound
