Unless you plan to get rid of all your 2/3* girls, you will run out of space before long, especially if you start saving up Manyus, Ampys and Dragons for a specific girl you want to pump up from 0 to max in one go.

Yeah I've expanded up to 100 spaces by now, but back then I was getting super lucky and kept getting multiple golds so I thought it wasn't a big deal. Only now do I fully appreciate the existence that is the gold dragon.
