2 hrs 16 min. and 23 seconds in.

No you did not read it wrong.
I had decided to continue the game to try and obtain everything and simply save to a different file, swapping back to the islands and power leveling when I could.
Alas, tragedy.
I saved over the wrong file.
Now I am forced to restart at an earlier point.

However, opportunity presents itself in the form of Selphie.
A nice little trick has me gaining 2 exp. every 6 seconds, far faster than before.

Still the first day so when I get strong enough, I might switch to battling Riku (he gives 5 exp. upon defeat, however at my current strength, Selphie's trick is still quicker.) upon reaching the twenty's.
I've also steeled myself to obtain 99 pretty stones, but that will come later.
