Zera is the 12th chapter of Fairy Tail Zerø, a prequel to Hiro Mashima's Fairy Tail. Zera confirms Yuri's beliefs, admitting to Mavis that she died during the Blue Skull's raid and had been a creation of Mavis' Magic ever since that day. In disbelief, Mavis tries to argue the fact, though she ultimately accepts the fact that Zera isn't real, allowing Yuri to see her; Zera entrusts Yuri with the job of looking after Mavis before disappearing completely.
