Check out my lists
As an adult, I try to stay away from stories with a highschool or lower setting, because well they make anime way beyond that scope and I like mature themes more now. I just don't connect with high school students. Though other trade schools, college, specialized school is fine for now. I like cute shit too. There are exceptions.
My love of anime started when I was young with Sailor Moon, Little Nemo In Slumberland and Ranma 1/2 when I was about 5, around 1994, and a few years later I saw anime on the Syfy channel.
They had a great lineup, but what stuck with me the most was Green Legend Ran !
I learned that anime could have stories that were beyond my current imagination and it stuck with me in my dreams for years.
As a preteen, I learned about manga while watching the original release of Toonami.
From there I absorbed everything I could get my hands on. Which was anything that Barnes & Noble had in their giant section down the street from where I lived, because torrents are illegal >..>
In my teens I loved Battle Angel Alita, Vampire Princess Miyu, Mars, Seriel Experiments Lain, Shingetsutan Tsukihime, Slayers, Tenchi Muyo, Outlaw Star, Tehxnolyze, Popotan etc etc
In The Garden of Sinners,
Rin:Daughters of Mnemosyne,
