UUUUG I just screwed up and read all 50 available chapters of BTOOOM. I just couldn't help myself. Other than rearranging the order a bit which could cause some continuity issues later on it seems to be following along the manga pretty well. You were right, not to give spoilers, there is some darker aspects to come.
That is the one problem with Anime from Manga adaptations. The temptation to compare and knowing whats to come. Or expecting something and the team behind the anime going a different route. Well that and filler episodes that serve no purpose other than letting the manga develop further because the anime caught up to it.
