Hello, I was under the impression that the manga chapters are released every Wednesday on "Shonen Sunday" and at the end of each chapter it tells you when will the next be coming out but... are they coming out earlier? I'm pretty sure on Chapter 423 it said 424 was coming out on Oct 9th but it's been out since Oct 7th at least. Can anyone explain this to me, please? Thanks!
