Pop Culture Equivalent: Moaning Myrtle
The akaname also goes by the name "filth licker," which brings to mind something either super gross or super sexy, depending on how depraved a person you are. I know where my mind went. Ladies ... Anyway, the gist of this spirit is that it has a long tongue and haunts bathrooms that have been extremely neglected. In these filthy, unkempt bathrooms, it uses its massive tongue to slurp up the bathroom goo and crust and hunka chunk that the maid hasn't gotten around to scouring clean yet. It's absolutely revolting in every way and could only be trumped by something like Gary Busey feeding you cheese as though he were a mother bird and you the baby.
"Mmm, someone's been eating avocado!"
Now, a long-tongued, shit-crust-eating monster sounds like a decent basis for something potentially terrifying and gross, but as near as I can tell from reading up on it, this is the limit of this creature's ambition in life. It won't eat you, it won't curse you or kill your relatives, it doesn't crawl out of the TV or rain blood or anything. It cleans your bathroom. If anything, it's a time and money saver; you just have to let your housework go slack for a while and this gross son of a bitch shows up and does it for you. That's not a bad deal.
