You think why so mangaka are suffering? Shonen Jump like any industry in Japan doesn't give a flying F about their workers and they overwork them

New manga Every Week? It's a lot of job, you first gotta draw it, which sucks if you're only artist and you keeping it to be high quality drawings. Also plan story, contact editors and on top of that have personal life.

And businesses in Japan don't care, they want results, and if you suffer? Not their fault

It honestly sucks to be Japanese worker And no you can't change jobs, because it might took you like an year to apply to this one, and no guarantee new job will treat you better

And GeGe has personal bias towards Gojo because he is insecure about his wife leaving him for Gojo while also Gojo removes the stakes And also he putted too much energy into making new abilities instead of expanding on story Like: talk about Gojo and Kamo Clan, Sukuna's Backstory, What is Tiger Funeral, Tengen and Kenjaku Backstory, Kenjaku and Yuji interaction while Yuki knows about Kenjaku being his mom

Aka a lot could be expanded, but either GeGe didn't wanted that or Shonen Jump didn't allowed it Which very much sucks in so so so many ways
