You know what never made sense to me?
Post-Dark Tourney spoilers
(SPOILER)It never made sense that Botan didn't actually know that Elder Toguro didn't die. I mean, if she is the grim reaper, wouldn't she have had to ferry him through spirit world as well? And if she did know he was alive, why would she not say something about it? Currently I'm only on episode 71, so no spoilers please, but I think that's a big plot hole.
