It's actually very hard to explain...
It's kinda like why there are more pngtubers than vtubers in poland and there are not so many furries there.
The same goes for Spain, where I don't know many people who watch anime or even know what this is.
I guess Anime is reserved for "European People of Culture" or something like that XD
After all, in my whole carrier, I only met like 20 people who watched anime and out of all my friends, only one (in theory) watches anime.. however, he only watches Dragon Balls and Naruto... nothing more.
I recently built him a new PC for gaming and making music on a MacOS KVM and he had like 7tb of pirated Naruto and Dragon Balls episodes XD
This was really amusing to see a certain logo of a very popular anime streaming platform in all those videos.
I told him to get a Dell SFF PC, do a 10tb RAID 10 setup and put all of them on the NAS and stream them via Plex but I guess he's too lazy to do that
