I am a red liquid that travels inside your body. I am pure and honest to you, that's why I won't kill you. If you don't believe in me, cut yourself a little near skin, my red color never lies. I to you, am like a dog to his owner: loyal by all means. When needed, I'd even fight until the end for my utmost purity, because it is a fact, without a pure me, you'd go extinct in no time.
But, my loyalty doesn't just stop there. I am a hunter. I live beyond your time to follow those who shortened the life that was your right. From every drop that spills on the ground, my red shadows and ghosts arise; stalking those who murdered life, who murdered blood.
Don't get me wrong. I'm not after revenge, it is never my intention. I am just a dreadful reminder. Not that I look scary at all. Imagine the sight of the hideous action that needs to be forgotten, but it never does. That is why they are afraid of me. No; revenge is the last thing I want, but the unrighteous wants that more than remembrance.
I know you just don't believe in me, because you can't see me. But, I am, a red liquid inside your body, pure and loyal, a hunter, a stalker and a reminder. Beware, I can be a red ghost; Thou shalt not spill pure living blood!
