Lucky Star and K-on for CGDCT
Evangelion for meta-commentary and deconstruction, to the point that future works that qualify often get called the “Evangelion of <genre>”
Fullmetal Alchemist Brotherhood and Attack on Titan for battle shounen
Bocchi the Rock for girls band anime, specifically
Lupin III: The Castle of Cagliostro for pretty much all of Ghibli
Akira for 90s anime


Aria was another early work in this area, but I don’t know how much it influenced later shows because this is so not my genre.
I’m not sure either how much ARIA influences later shows either. Apart from Tamayura which is by the same director. ARIA is definitely my favorite though 🥰. I went with Yokohama because it aired much earlier (1998 vs 2005).
