NOTE: I'm saying this with no knowledge of how Demon Slayer RPG3 is going to be made, I'm using knowledge of DSRPG2 and assuming it'll be similar to DSRPG3.
Instead of having to pay, win, or earn things like Race Resets, Breathing/Art Resets, and Nichirin Resets, Maybe make it resettable by in-game currency. Since Demon Slayer RPG3 will have no PTW features, it'd make sense to implement something like this. And if done, it should be quite pricey.
