This is a great story
I love the diversity of the character personalities that I've read about thus far-- Crys definitely seems like a character I'd like to get to know, and the plot is very intriguing; not to mention what a cool idea the nicknames are. You've missed a few grammar errors (just skipping over a few words) but it doesn't distract me much.
Keep writing; I'd love to see what happens next! ^^
