Anyways i also think that Chuuya SHOULD NOT be the Port Mafia boss to be totally honest witchu. If his entire experience with the Sheep, and the way he cracked under pressure as the interim leader during cannibalism, and like, THE BEAST EPILOGUE, had anything to say it's that Chuuya's not fit to be the leader of an organization such as that.

Bc Chuuya's good at adapting, he's good at spur of the moment decisions. He's good with battle tactics. We see his actual leadership abilities shine when he's commanding the mafia troops to protect the city during the guild arc. In cannibalism, his plan to rush the ADA with a full frontal attack was a SOLID idea. But he loses his advantage as soon as he hesitates and opens the table for negotiation instead.

BECAUSE Chuuya's not good at playing the long game like Mori or Dazai. He's reactionary and it's his nature to get overwhelmed by his emotions. He takes on too much responsibility but loses focus due to personal reasons. That what happens in 15 where he blows off the Sheep to go on a life changing field trip with Dazai. That's why he was taken out of the picture so easily to go on a life changing field trip with Ranpo in Cannibalism. (Damn maybe this is why he's on a life changing field trip with Fyodor as a vampire currently).

Essentially even though Asagiri has been really tying Chuuya's character with the themes of leadership, we've mostly been shown why he wouldn't be a good fit. Either this plot point will trend towards Chuuya actually learning how to be a good leader OR he won't end up as one. IN ANY CASE what we know abt Chuuya makes me really think that being the Port Mafia's boss is a terrible idea. He's not fit for the role and frankly, I think he'd hate it.
