 If you liked Haikyuu!! Karasuno Koukou vs. Shiratorizawa Gakuen Koukou |  ...then you might like Shingeki no Kyojin Season 3 Part 2 |
hmm this recommendation might sound awkward but both of these anime have similar things like, Both are heavily based on strategies where one is trying to outsmart the other (titans vs humas, or kurasuno vs shiratorizawa) both have heartstopping actions, and breathtaking animations, both are the best the franchise have ever produced till 2020 september, if you watch one you can feel the same amount of thrill in another one also, even if the plot and story are totally different
