Your favorite manga of big mangaka they wrote BEFORE their respective magnum opus?
I find it really fascinating reading up on what great people were doing before they became THE great people, sometimes even spying some elements that would become quintessentially them. Granted, I haven't read THAT many works of this kind, but enough to have two favorites.
- Baoh the Visitor (Hirohiko Araki, JJBA). It's a relatively short series Araki wrote directly before JoJo and, honestly, it has enough trademark bizarreness I tend to think of Baoh as "JoJo Part 0", which is exactly why I love it. It also has a cool OVA and its protagonist, Ikuro, appears in JoJo fighting games. Funny enough, Ikuro, in his empowered form, Baoh, carries a lot of similarities with Pillar Men, JoJo Part 2 villains.
- A Man Called Ribs (Koyoharu Gotouge, Demon Slayer). Out of one one-shots Gotouge has, this is one that wasn't even really intended to be serialized, but I find the protagonist, Abara, interesting, a blind exorcist guy who can only see shapes of humans' goodness and evil (he's also just a cute little goober). Gotouge's pre-KnY one-shots also take place in the same universe and it's kinda fun to see cameos between them. Pretty sure Abara inspired Douma in KnY with his odd disposition and the one-shot's antagonist inspired Daki with cloth-related powers.
Any fun pre-FAME work anyone can bring up? And I don't think Toriyama's Dr. Slump should count, since it was already kinda of a big deal, but if you like it, why not? Yap away!
