I am still not sure about having an Empty Slot 4, there might be so many characters that the fans previously requested and my personal addition that it will fill up all the spots. But if there is going to be one, then I suppose we can give those characters a second chance.

I thought Harmony of LOLZ Rebirth had 60 characters + transformations, or maybe you are referring to another game I made?
