I can't seem to get Sung Tai Ki or Rumiko to drop from the Ninja Village Boss Battle.
When I first started playing I planned on getting all the girls from a location before moving on to the next, but I was stuck on the Ninja Village for so long that I gave up and moved on.
Since then I have always spared the last of my combativity on the ninja village in the hopes of eventually getting these two girls to drop, but I have still not had any luck.
Am I just having bad luck, or is this a glitch? (have gotten all the girls from every other location, all with a lot less effort)
