old anime

What pre-2020 completed anime do you like?

Meaning it has to have been completed prior to the covid anime babies.

I like KHR, Zetsubou sensei, and Narita-verse.

There are actually a lot more I could list (like madoka, nodame cantabile, lain, FMA, NHK etc etc) but everyone knows those. Give me something niche. something you like and was forgotten because of the covid anime babies.
