User blog:OriginalFanBoy2/Pernida and Mimihagi

Quick question. So it was recently revealed that Pernida is the left arm of the Soul King and several chapters before that we were introduced to Mimihagi, who is the right arm of the Soul King. So they are both former parts of the Soul King (the Soul King has no limbs which is probably the way the Shinigami restricted the Soul King's power) yet Pernida is referred to as a Quincy and one is referred to as a god. Unless I'm missing something, why are they classified as two different species? Shouldn't they both be listed as gods or as Quincy?
