I think kris deltarune would be doom-bound, I see a lot of ppl but them as heart cuz of the soul but kris really doesn't seem to have any heart characteristics (atleast to me). Theyve been doomed by the narrative to have their life taken over and are 100% "quite irate about their lot". Idk what class id make them tho.

I think the player would be blood-bound, bc of how you're meant the play the game collecting allies, theyre class should depend of if you do the weird route or not. If you do then id say prince of blood.

Susie is 100% rage player, idk if id put her as a knight like most ppl tho, maybe a rouge.

Ralsei prince of hope
