I’ve always devoted more of my time & money to anime than manga, but these are the manga I’ve been the most invested/interested in;
1. Battle Angel Alita (my #1, no contest)
2. Oh My Goddess
3. xxxHolic (it’s not porn, really)
4. Chibi Vampire (anime name was Karin)
5. Yotsuba (same managaka as Azumanga Daioh)
6. Shadow Star (via Super Manga Blast - kind of a cross between Parasyte & Madoka Magika)
7. Monster Musume (guilty pleasure)
8. Blood Lad
9. Gleipnir (since a season 2 is questionable)
10. Spy x Family(started, but currently waiting on the anime adaption)
