Well you know an axe is an axe there's worse ways to end a series, and he can always make an omake for the final volume showing us what BJ has been up to after facing the boss, I think he could have spent some pages in that instead of that silly fight in the church
I agree with the other comments Usogui was way better
I like it, but WHY did Jyungo suddenly go to Brazil?
haha oh well
thank you team duwang for scanlating this great manga!
Since Jyungo became a mafioso people are assuming that he became the leader of Malandrage Kartel and ended up absorbing both Lanca and Bandeira (why is he now baiting Ichi to go after him in Brazil, despite leaving her side and becoming a mega mafioso? No idea, maybe he is still running away and Ichiri's mom is mayi g cupid? Meh)
But none of that matters because we know that in Usogui Baku will become the boss of MK
So anyway that's the excuse for why Machado could be in Brazil, and we can then just assume that BJ and the boss died offscreen, and ignore the whole subplot with Ichiri's dad since they never meet, the guy was a dead beat, and is mostly a plot device than a character
After writing this I am not even sure I want an omake, 10 extra pages wont change much, I guess the most cost efficient way to actually wrap things up would be to have Ichiri talk with her mom, and call it a day, she does some tourism in Brazil then goes back to Japan to live her life
