The Port Mafia

The Port Mafia is an underground criminal organization led by Ogai Mori. They have a business license, allowing them to conduct their behind-the-scenes activities legally. The Port Mafia is also known as the "Night Watchers" of Yokohama.
But all this is just a description, the problem itself is that.
Recently, the water in the area where the Mafia was based was cut off, and now all of its employees go to the communal bathhouse.
Who would let their senpai get tired? Certainly not Higuchi. Higuchi meticulously and reverently asked Akutagawa, her secret lover, for something to carry, because she couldn't bear to see him strain himself further. Gin, Ryunosuke Akutagawa's sister, walked calmly beside her brother, oblivious to Higuchi's concern; it wasn't her business. Kaji, as always, bounced along behind, having come up with a formula for creating hyper-powerful bath bombs. Mori himself walked behind everyone with Koyo, chatting peacefully and informally. Chuya carried all the necessary bathing equipment; after all, the Mafia is the Mafia, but washing is important. You, too, walked along with everyone else; you needed to wash your hair, exfoliate your skin, do your facial, in short, you had your hands full.
