Black Clover

Synopsis

Hundreds of years ago a young Licht receives his four leaf Grimoire. Patry, a younger elf, asks Licht about rumours that humans are planning to attack their village but Licht assures him there can be peace. Licht saves a human woman named Tetia and meets her brother, a Light magic user who also possesses a four leaf Grimoire. He suggests combining elven magic with human magic tools to create a peaceful elven/human society. Licht and Tetia eventually fall in love, conceive a child and plan to marry. On the day of the wedding the elves are murdered by a Light magic spell, leading Patry to believe Tetia's brother was the murderer. As Patry dies he sees a distraught Licht cast a forbidden reincarnation spell. Patry awakens centuries later in the body of William Vangeance and realises he is the only one who fully reincarnated. He retrieves a four leaf Grimoire and uses it to reincarnate Rhya, Fana and Vetto into suitable human bodies while passing himself off as the real Licht. To resurrect the entire elven race Patry began his search for all the magic stones stolen from the elven village. In the present Patry sacrifices Sally, Rades and Valtos to fuel the resurrection spell while Yuno completes his transformation into an elf.
