So let me get this straight.
MD had all the chapters hosted for free, then decided to partner with MangaPlus because they were a publisher that hosted stuff for free, only to then be made to take all the chapters down by Shounen Jump bar the first and last three, to promote their subscription reading service, which you have to pay for on their website to read Chapter 4-113? I'm also taking a punt that all of the other major online manga sites also have those 109 chapters missing too?
So I guess my options are to either bingeread the entire manga in 7 days of the free trial (I can totally do that) and then keep up to date with the free chapters, or to hope that somehow they become free again?
Can we just hurry up and destroy publishers who do things like this? I gladly buy physical copies of things I support but not everything is easy to gain access to and doing something like this just to promote your streaming service is a one way ticket to having people ignore your stuff.
