Fairy Tail. Volume 19

The "Sixth Covenant" has targeted the guild "Cat's House," since its founders once created "Nirvana" and are still capable of sealing spells.

To counter the scheme of the "Sixth Covenant," Erza and Gerard engage in a fight with Midnight, the strongest of all villains.

But as soon as Midnight falls, another personality awakens in Master Brain named Zero, capable of monstrous destruction.

Everyone will suffer: both enemies and friends. What will "Fairy Tail" and their allies do?
