It's a year after Natsu and the guild had been back. Something wasn't right... Lucy Heartfilia gets kicked out of Fairy Tail. After being kicked out she finds out she has a new magic she never knew she could get. Having to hide herself, she dyes her hair red and calls herself Nashi Heart. After rejoining Fairy Tail, her arrival leads to a war against Lucy and a Mystery person that says they will kill Lucy. Lucy expects someone important to come into her life. But loses them to a tragic event.
Will Lucy win? Or will she die keeping the secret of being Lucy Heartfilia?
