Am I the only one who doesn't get the last Update?

If you mean Chapter 37, Doumeki became part of another yakuza group, this time, his Boss is Tsunakawa. Tsunakawa took him in as a favor to Amou-san, after the group headed by Yashiro disbanded. Doumeki was originally just a caretaker for the little girl, but he proved himself to be a valuable member of the group (he managed to save Niki without any mishaps, he's assertive in collecting money, etc.). At the end of the chapter, we see Doumeki save one of his colleagues from being ambushed. It is important to note that the colleague calls himself an "underling," meaning that Doumeki has already been promoted to a team leader.
