Everyone’s starter anime is death note.
I don’t count sailor moon or dbz cuz you watched those as a kid and assumed they were cartoons.
I mean when you got “into” anime fully aware of what it was and actually became immmmmmersed in this bizarre weeb culture.
It’s usually death note.
Trigun, but I did go through the Light-is-right phase until I watched Code Geass.
Outlier.
Although I guess it was naruto or Bleach for some people.
I got you all beat. The Original Big 3. Akira, Vampire Hunter D, Ninja Scroll. And those when I was a child of 9. Death Note was WAYYYYY down the line.
Akira and bugglegum crisis. Death note was the tail end of my anime addiction phase
