This is the path I have chosen to walk D.gray-man story

A shy girl who starts to understand that she is the saver to man kind, and need to destroy these things called Akuma. But finds out later that she herself is a bad guy, and who will she choose? Will she join the Noah and help them with their quest to destroy innocence, or stay with the Black Order and help them rid the Akuma and Noah's and save humanity.

I don't own a thing about D.gray-man, the only things I own is Akira and other characters who don't appear in the anime or manga.
