Mira have 3 extremely powerful demon....no one can defeat it......satan soul easily break purgatory armor......demon halphas can defeat armadura fairy....and demon sitri is rival of nakagami armor....so my opinion is mira is stronger and powerful than erza,gildart,natsu,gray...master makarov or maybe mavis
