We are using a combination of the power ceiling and scaled cost point buy rules. Each character gets 10 points and is allowed a maximum of 10 additional points through weaknesses. Character advancement follows the scaled cost format.
The game is still set in Golarion, just with an Anime spin (see Inspiration). PCs should still fit within Golarion lore, though with a greater tolerance for cat ears. Golarion societal norms, religions, laws, etc. still apply. Each character should still incorporate a campaign trait.
