One is the original translation
what one??
The chapters with Akumakira are more later than the first chapter and you see better quality. They haven't posted since the end of season 1 tho so after chapter 100 of their own is where you see the old first chapters including the latest uploader where you understand what's happening but even a few names have changed with a different translation
Or at least thats what I think you meant by the artist changing. I still see the same drawings but I started reading only Akumakira uploads so idk
is it just me or they changed their artist? Orr
