Hmm, I wonder if these could be considered death flags... Seriously though, could they foreshadow any harder?
Also what's with the B team leader being an A rank? Your guild has multiple S ranks, just split the S ranks between the teams. If something really tough comes up you can postpone until you have two S ranks available. No reason to have one teams without an S rank.
In addition I like how the main guy from the B team looks like Jin-Ho.
