As I recall Mizore is how you learned about yuki-onna. And yeah, a bit of research shows that Keito is a sadistic minor villain from the show, and is indeed a jorōgumo. She even kind of looks like how I described Yua’s in-between form (a woman with black and yellow spider legs sprouting from her torso). Hers sprout from her abdominal muscles, which is a look I considered, but I felt like it would be potentially gross for the readers to imagine. Granted, that was no doubt the intended effect with Keito.
I did actually find a sympathetic jorōgumo story after I left that last post. It seems episode 7 of Dororo features a jorōgumo who, after narrowly escaping combat with the protagonist, is rescued by an unsuspecting human whom she eventually falls in love with. Also, while Rachnera from Daily Life with Monster Girl isn’t a jorōgumo, she is technically a non-bad spider woman. I wasn’t counting her before since DLwMG is primarily a comedy.
And yes, anime can absolutely be culturally enriching, especially the series that introduce mythology or aspects of Japanese culture!
Thanks!
