I would say there is a good chance to get both Mare or Zebra in their dungeons since i got them both on my second run or maybe it's  just my luck lol.

but for Luna go to St. Lamia and visit the light area and go to either Conqueror of the Heavens, Knight of the Light and for Mifune go to the dark area and visit The Death-beckoning Devil , Dwelling of the Souls. They appear more often on those stages. Shouldn't take too long to get them.
