The only satisfactory ending to this Republic arc would be for the sacred tree to get utterly destroyed. It would basically shatter the very core of that corrupt country. This particular arc has such a stupid basis, Leon losing his ship because someone else with no right to it used it as betting collateral, that it's difficult to really care about it. It's already challenging to care in general with Leon's difficult personality, but at least every now and then he has those great moments. But it would be better if the foundation for those great moments made sense.
