According to Stats, my MPs are 156,548 (184,175), and I can still raise Maximum MP... Looks like a bug to me, since in the main screen MPs are shown as 156,548. I think I blew quite a few pixels there!
Equipping Spirit items causes your MaxMP to drop. You can continue to buy MaxMP using Pixels until the base number (the number in the brackets) reaches 260,000.
