The Ame Sisters
On the verge of dying, Heartfilia Lucy or should I say XXX XXXXX XXXX, becomes who she really is. Who does she owe it to? The guild. Ever since Lisanna came back they all abandoned her. She's been left in the dark, with nothing but grief and sorrow no one by her side. Because of this all the sanity she has, have slowly slipped away, and that leaves her a depress mess and suicidal. Once the guild finds out though, they think it's a brilliant idea to help her with it so they took her to the guild, and abused her in many ways.
In the end she took Erzas sword smiling saying goodbye and thank you before cutting her hand off where the fairy tail sign is. She then stabs her heart and eyes. All shocked they finally realized what they have done. They all run out to tell master at the council, but when they leave a bright light bursts from her setting her free.
