Mirajane (Edolas)

Edoras Mirajane is unchanged although everyone elses personality is. This raises more questions for Charle as she comes to the conclusion that the people they are with right now are not the Fairy Tail members from Earth Land. The most likely reason why she didn't change would be this: Before Lisanna died, Mira was tomboy and tough (like Edoras Lucy) but when Lisanna died she turned good and powerless. Since the Erdas Lisanna is still alive, Mira starts out as good, as the other Mira starts out tomboyish, and since the good-natured Mira sister is still alive, there would be no change in personality.
