210 here I think (at least thats what it was last time I checked).
Kinda like to have extra space when the "farming manyu" mood kicks in

however lately I feel the need to expand the item inventory. Since you tend to fill in those item slots rather fast.
I think its worth throwing, around 10-20 Flower Gems into expanding the character space in the early stages of the game. After that you should be pretty much set for the long run.
