I like this analysis because it's a bit deeper than just mentioning the media references present in the intro; it contextualises them, and connects them to the plot of the anime.
The Makima wallpaper is 2560x1440, while the Yoru one is 2560x1080. If anyone wants I can redimension either or both. (Note: contrariwise to what Imgur is claiming, neither is NSFW, they aren't even suggestive.)
