The Vermilions

As a lightning devil slayer and the daughter of Mavis and Zeref, Lucy Vermilion has always been targeted, from dark guilds to the Ankhseram's psychopathic younger twin, the God of Life. But never did she expected herself to be transported back to the year x771, transformed back to the 16-year-old she was. Neither did she expect for herself to unknowingly save her rival from his power-hungry father.
