You know, Mabinogi should make some visual novel DLC where you get to romance Nao, and how the romance progresses would depend on how you acted both in the main game and in the DLC section. Max out the good karma and you get to have Nao as an in-game wife and get free resurrection, with the option of her saving your ass in major boss battles. Max out the bad karma and you turn her into a minigame where you enslave and fuck her for gold and soul stones, and have the option of selling her as a sex toy to avoid major boss battles.
