The whole celebrating with beer thing brings back memories of the chinchirorin group, I hope these guys don't fuck up like Maeda and Miyoshi... But it seems they really did say Kaiji's name in front of the car chaser, one of them looks really sad when they talk about that.
This was such a wholesome chapter but it's very worrying, feels like it'll come crashing down soon, these guys might have fucked up or even sold Kaiji out on purpose.
