Demon Child

Luna Dragneel. Daughter of Natsu and Lucy. A secret that was kept from her since she was born. Her demon side. Inheriting it from her father, also used to be known as E.N.D, she begins to lose control of her side when it awakens on a job. As a Demon Slayer, it is Sylvia's job to slay any demon she finds. Sadly, this now includes Luna. The guild finds out about Luna and splits in two. Sylvia's side. Luna's side. To defeat the demon side (which could possibly end her life), of the girl who fought by their side for as long as they've known each other. Or to accept for who she is and help her control her power, but to fight against the girl who has always been there for everyone. It's something that only results in, a Civil War.
