Anime: watching Star Blazers on tv during the late 70s & early 80s even though I wasn’t familiar with the term at the time. Started watching shows like Ranma 1/2, Slayers, Tenchi Muyo, etc on VHS tapes in the mid 90s before moving back onto DVDs. Have been using streaming services to watch anime for about 10 years now.
Manga: have never been as into manga as much as anime, but Battle Angel Alita was the first title to really get my attention with it’s art & story (first saw it in a bookstore in the mid 90s)
