I think you should add a character named Greta

Great story! I finaly found it!

Ummm... Purple eyes that mean you shall be an assassin? And you have no choice in that matter? An original idea, for sure.
The plot seems interesting though, and the characters are interesting.
I am curious what in the world Nitro orbs are, other than "your life force".

I love where your story is going! It would be really awesome with a little more detail on certain things like the rock thing they are born with, what the car looks like, and the bubble thing that keeps him from getting murdered by the rain. Over all really good. I can't wait to read more.

Cant wait for the next chapter!
