A couple weeks ago I was listening to the Nona the Ninth audiobook (as you do, for nearly a year straight) and noticed something towards the very end of it where (spoilers for NtN) the events at the end of the book don't end being frantic until Alecto's name is said exactly three times in Nona's hearing. I didn't grow up with many spooky stories or folk tales or whatever, but I DO remember a tumblr post where they were joking about looking into the rear view mirror of a car and chanting "Bloody Mary" three times to summon her behind them as they're going 50 mph or whatever. Something like that, anyway, but my brain made the connection.
Today, @spaceswordblaster reblogged one of those "have you seen this movie" polls about a Bloody Mary movie. That reminded me that I had wanted to go to the wikipedia page and read up on the common way(s) the legend is invoked, because if it actually worked the way that I was vaguely remembering, that would be a neat parallel that I could ramble about sometime!
The wikipedia page itself gave me a lot of related ideas but it also linked to a similar myth from Japan about "Hanako-san." Having only cursory exposure to horror movies and the like, I was like "is that the Ring girl?" and clicked on that link; it was not (I think the Ring girl starts with an S but anyway).
At the top of THAT wikipedia page was a disambiguation section, which included "if you're looking for the manga, see "Toilet-Bound Hanako-kun" and I was like w h a t (until I read the Hanako-san page, at which point is still sounded hilarious but made sense).
So then I went to the Toilet-Bound Hanako-kun page, as you do, and saw it had been adapted into an anime in 2020 and there was a reboot coming out in 2024 (I think?). So I looked THAT up and it's free on Crunchyroll and I was like "okay I'll watch one episode just to see what it's like, then I can go do the things I need to do for the day" and now I'm on episode 7/13 or something like that.
So that's how my day is going, rofl
