Fairy Tail: Zeref's Awakening, Mage Hunting ArcEdit
Iris encounters Mages from Fairy Tail as they are setting out to investigate the disappearance of Mages from several legal guilds (including their ally, Lamia Scale), amidst rumors of "Mage Hunting".
She encounters them several more times afterwards, some of those times as a boss, and is revealed to have a connection with the Masked Mage behind the incidents. She is also revealed to be able to transform into a Dragon.
