Yeah, Bakuman. It's by the writer/artist duo that made Deathnote and reading it as a teenager really dulled any sort of entitlement that could've bloomed. And they were writing a fantastical story that was *approved by Shueisha themselves for publication*. So reality is FAR worse than the fun aspirational story Bakuman was packaged as but it's still incredibly useful if you have no frame of reference for what the industry is like on the ground for creatives making your favorite shit.If anyone wants to understand the amount of work these manga artist put in. I recommend people to read bakumon (i think that’s what it is called, a manga about a manga artist) and people will see how much hours they put in.
Funny enough, the teen protags' big insurmountable rival was clearly designed partially after Oda in his youth. Well now even if mega genius Eiji Niizuma was in his 50's he too would be forced to slow down or die.
Warning, it does have one of shonen's worst romances (which is really saying something), so endure that and enjoy the meat of the story about the industry itself
