Seems to be based on a modern japanese urban legendwho the fuck is this? is this a new demon? kinda wacky but I like it
There is even a short film about it
Turbo-Granny (2017)
Didn't even know it existed till this daily demon showcase, but it seems she appeared for the first time in Soul Hacker 2
It's 1AM over here no way I'm watching this creepy pasta before going to bed lol. I'll look in the morning though.
