Wano started with episode 892 which was aired on June 23, 2019. It's episode 1009 now. 117 episodes in total with $90k per episode budget.
That's total $10.530m budget so far.
Demon slayer season 2(11 episodes) cost around $1M. But it took more than 2 years for this new season to come out.
If Toei worked good, they could have pulled it. We could have good Wano arc with 50 episodes with better pace at much lower cost than what they are giving us. They are killing the business for some outdated TV channel.
Gives me Warner Bros vibes.
p.s. I done the math using animegalaxy numbers.
Budget doesn't matter when it's seasonal vs weekly
Budget always matter. If you spend money on hiring good team, you get quality product.
Also look at the sales Demon Slayer anime generated. The story is not that great and new. But the numbers are staggering. It is sold like crazy.
