Paint the World Different Colours

This is the rewrite of Koukyo no Yuuyami. There will be major changes in characters, plot bunnies, and theme. Remember this is a D.Gray-Man Fan Fiction.
This is a story about three girls. One a 15 year old girl who fears men and wears a mask to protect her secrets. One a 17 year old girl who was forced to grow up quickly after losing her loved ones to Death. And one an 18 year old girl who tries to protect the two she calls her sisters from the monsters of the 15 year old's past and the 17 year old from the grief of losing her loved ones to Death again. Follow them as they search for acceptance, peace, happiness, and most importantly- Love. Watch as they fight to protect all of mankind, but how can they protect something that they have no faith in? How can they protect their loved ones when they're unable to protect themselves from the skeletons in their closets? Watch as they finally paint their dark world with different colors.
