Fairy Tail Vol. 20 — Manga Raw / Buy Official

In the middle of the S-Class trial, the worst possible visitors land on sacred Tenrou Island. The dark guild Grimoire Heart, bent on resurrecting the Black Wizard Zeref, launches an invasion under Master Hades, leading his elite Seven Kin of Purgatory. Suddenly there is no more trial — the members of Fairy Tail are thrown into all-out war against one of the strongest enemy forces they have ever faced. Worse still, the real Zeref lurks somewhere on the island, and his very existence hides a truth that shakes the foundations of the whole story. To protect their comrades, Natsu and the others steel themselves and rise.
