|Base of Operations||
The Port Mafia (ポート・マフィア, Pōto Mafia?) is an underground organization run by Ōgai Mori, based in Yokohama, Japan. They also have an Ability Business Permit allowing them to conduct their activities in a "legal way".. They are known as Yokohama's "Wardens of the Night".
According to Higuchi, the Mafia has dozens of enterprises under their control. It also exceeds in politics and as well as economics and its influence is found many sections of Yokohama city. Those who defy them will only burn and not survive.
The Port Mafia divides its power largely between its boss and his five executives, who answer solely to him and lead their own factions within the mafia. Originally, four executive positions were filled. As of now, only two surviving executive positions are known, but three occupied. Mori keeps Dazai's executive position reserved solely for him - somehow expecting him to return.
A major faction of the Port Mafia is its guerilla attack force, led by Ryunosuke Akutagawa, having succeeded his former mentor, Osamu Dazai. Working alongside him is Higuchi, who largely acts as his right hand.
A large number of mafiosi are low-ranked, such as Sakunosuke Oda. Such ranks deal with many lowly and menial tasks such as managing security for paying stores and settling disputes between paid allies and their interpersonal conflicts, or even being used as expendable assets as what Mori stated in Dark Era.
