Hello! I just finished watching the anime and I want to continue following the story. From what I've read the anime is supposed to cut in chapter 84-86. Were there any arcs from the manga before chapter 84 that were not adapted? Also, where can I read a good translation of the manga since from my understanding there are a lot of bad ones? And one last thing, from what I've understood theres something called gaiden, and a season 2 of the light novels. Are those adapted in the manga?
