Do note that if you're doing a true reset category you can't use the bed to skip the intro, it only works if you have a save file that's already beaten the game, or if you delete that save without exiting the game (i don't think the latter counts as true reset though, but dont take my word for it idk)

Enemies in this game don't die when defeated (HP hits zero), they simply run or fly away. Likewise, King Card doesn't die when defeated either, he merely gets overthrown or falls asleep (depending on route). I say if the king is defeated by HP hitting 0, it would no longer count as pacifist. (But I suppose the mods would have to decide on that one, 's just my opinion)
