Why Is Anime Obsessed With Power Lines?
Because that's what Japan looks like, duh! Any place in Japan has basically power lines all over the place, even in cities like Tokyo.And also because it's easy to draw and show for 5 seconds in every anime to save on the precious animation budget because it's super static and goes everywhere. Added bonus it can be added into any decor and you would not notice it's the same pattern imported all over again in between animes.
