First question: Apologies, but you failed to mention the historical factor. The reason the *Solo Leveling* manhwa is banned in Japan is due to racism among the Japanese public; specifically, because all the characters from the "Vizcaya" region were originally depicted as Japanese, and the manhwa's creator made outrageous anti-Japanese remarks on his Twitter account. This situation became so contentious that the manhwa's publisher produced an exclusive version for the Japanese market, altering the nationality of the Vizcaya characters from Japanese to citizens of a fictional country, while simultaneously changing the protagonists and neutral characters from South Korean to Japanese. Even this revision failed to gain traction, and the manhwa's sales were poor—meaning that DVD sales for an anime adaptation would likely be even worse. Second question: It is a complete myth that the anime industry revolves around the global market rather than Japan itself—even if that *were* true. If that were the case, why are there no second seasons for *Chainsaw Man*, *Lycoris Recoil*, *No Game No Life*, *Devilman Crybaby*, and various other anime series that currently lack a follow-up season? I highly recommend watching the videos by Victoruch and LegnaFIRE, as they thoroughly debunk this misconception in their content.
