She's learned Mirajane's job pretty much already, so this leaves Mira to go off and rejoin the active mages again. And apparently, Master Makarov never downgraded her from an S-rank so she still keeps her rank. All good in my book, Kinana's very pretty and we get to see more of 'Demon Mira'. Win all around
I want to see more Bisca and Asuka-chan!!
