>>280768602>The Demon Slayer anime began when the manga was almost finished.Sure if you add on almost 2 years.
>Plus, wanting to collect a manga you discovered through an anime, regardless of its quality, is quite common.Hardly, Seven Deadly Sins had a massive dropoff in viewership for the anime and manga, and obviously something like Black Clover or Boruto have been struggling. Chainsaw Man got a neat bump from the anime but it's also had some real problems following part 2 because readers are losing interest.
It's more common to see a cliff dropoff when an anime doesn't match up than it is to see people a year on making sales raise even higher than before in general, let alone to that level of phenomena. DS for whatever you may say issues it had certainly doesn't have one with retention, seeing as the new movie managed even better than the previous opening.
>I haven't read Kaiju Number 8, but this is interesting. If you have more examples of manga doing that, then it could be considered DS legacy.The obvious one is going to be JJK, which seemed tailor made to be a DS competitor, but even in long running manga you've seen massive changes in artstyles. Bleach absolutely did not look like it did in the manga when it returned for Thousand Year War, and what did they do? They added more flashy effects like a new Anime-Only Bankai that just so happened to be close to the style of DS, complete with japanese tapestries, to name an absolute minimum. Looking over the new Shonen releases are going to give better examples directly than I could.
