Current Arc

Later, Erza and her team began to go a mission to hunt a wizard hunter but she gets surprised when she hears Lucy is going to fight a Dark Guild.

Magic & Abilities
Erza is the strongest female member of Fairy Tail and one of the only five S-class members of the guild. Thanks to this strength, she had been considered for Makarov to be the next Master, but he said that Erza was too young.

Erza uses Ex-quip, a type of magic that swaps weapons and armor at will. She is noted for her ability to exquip quickly and is the only sword mage capable of exquipping armor while fighting, earning her the nickname "Erza the Titania", and is well known in the continent, not only in the city of Magnolia. Her strength is so great that even strong mages such as Natsu and Gray fear her; this fear immediately ceases their bickering in her presence. Despite her great strength, she recruits Natsu and Gray for the mission against Eisenwald. Mirajane claims that this team is the strongest in the Fairy Tail guild; however, this does not imply that Gray, Natsu and Erza are the strongest in Fairy tail. Happy said that Erza's magic is beautiful because it causes a huge amount of blood to spill from her opponents.
