Unlikely, given that the game itself is free, the limited storage capacity is the main incentive for players to shore up cash to pay the developers and publisher. Other than that, you can also opt to throw away swords that you don't have any particular use for or just flat out loathes.

Think of it as optional DLCs that'll make yor life better somewhat but you don't really need them if you are good at management.

If you have a credit card, there's also a way to earn 500 free DMMP that you can spend to buy at least 10 more sword slots, but from then on you'll need to fork over your own money.
