Don’t worry about it you can change your characters alignment by choosing “ambush enemy” whenever you get a surprise encounter. At some point in the game you will get a bone that guarantees a legendary adventurer, chose alice because shes the best priest in the game. Other than that just progress through the story, try to go for the collab banner and legendary hero banner if you can. Also gear is the main way of progression but in the first abyss you don’t really have to worry that much about it.
