This series has such a detailed take on the scam-like nature of the financial market that I kind of want it to never change into the fantasy death game post apocalypse the time travel setting promises. I fear that would make it a much more generic series.
How many series, including other medias, can you think of that talks about how the International Monetary Fund destroy smaller countries while under the pretense of helping them? How many manga criticize big corporations? Not enough considering how influential those organizations are in the real world. Very few even criticize them by comparing them to demon lords or monsters, while those interest groups are destroying our own world, causing death, the climate crisis and poverty worldwide.
On that note, not enough media criticize the military industrial complex either. It could be the US job to create that, but its media is too in bed with it. That's why the criticism to financial market has to come from Korea (which has suffered in the hands of financial market) and during the 90's (because today Korea is more ideologically aligned with these financial markets)
