Yoshiwara

Yoshiwara is a district located in Tokyo, Japan, and it serves as the main location of the Entertainment District Arc. It is a red light district, a location with a high concentration of prostitution and sex-oriented businesses.

History
Yoshiwara was founded in the Edo period of Japan, where it quickly became a prominent district for prostitution and sex work. The highest ranking courtesans were known as Oirans. Three of the most famous and prominent pleasure houses in the district during the Taisho period were the Tokito House, Kyogoku House, and Ogimoto House.

For about a century, before the latest intervention of the Demon Slayer Corps, Yoshiwara became the home and the lair of two extremely powerful demons: the siblings Daki and Gyutaro, the dual holders of the position of Upper Rank Six of the Twelve Kizuki. Owing to Daki's great beauty, experience in sex work, and her unique Blood Demon Art, they made Yoshiwara a successful hunting ground, where they captured and devoured numerous victims over the years. Daki's nigh-immortality and subsequent attempts to hide her true nature started the urban legend of a incredibly beautiful but also incredibly cruel Oiran, the stories passing down generations. Most attempts to stop them by the Demon Slayer Corps were unsuccessful, with Gyutaro having killed 15 Hashira and Daki having killed 7.

During the Taisho Period, Sound Hashira Tengen Uzui was given the mission of hunting down the demonic presence in Yoshiwara and sent in his three wives, Hinatsuru, Makio, and Suma, to infiltrate the three most prominent pleasure houses in the Entertainment District and search for clues on his behalf. When all three suddenly stopped providing him with information, Tengen began his own investigation to save them and find the demon himself.

Tengen attempted to take Aoi Kanzaki and Naho Takada as he needed female Demon Slayers to accompany him. His forcible abduction of the two was stopped by Kanao Tsuyuri, Sumi Nakahara, Kiyo Terauchi, and Tanjiro Kamado, who then proposed to accompany him on his mission instead, alongside his partners Zenitsu Agatsuma and Inosuke Hashibira. Satisfied with three willing Demon Slayers, Tengen began the mission to save his wives and the people of Yoshiwara.

Upon arriving to Yoshiwara, the trio were amazed by the bustling city and separated from Tengen, with Zenitsu being beckoned by the girls of the district, and Tanjiro and Inosuke in awe of their surroundings, having lived in the mountains their entire lives. They regrouped at a safe house and were assigned disguises in the hopes the three Demon Slayers could be taken into the three most prominent pleasure houses, as Tengen assigned his wives to. Tanjiro, due to his diligent and hardworking attitude, was taken first and went to the Tokito House, the same house that Suma was assigned to.

Later, Tengen, Zenitsu, and Inosuke watched as the Oiran of the Tokito House, Koinatsu, travelled with her procession to a new client. Inosuke was then spotted by a chaperone of the Ogimoto House, the same house that Makio was assigned to, where he was promptly taken in. Zenitsu was left last, with Tengen assigning him to the Kyogoku House, the same house that Hinatsuru was in, much to the latter's displeasure.

After the three settled in, they each began their own investigation. Inosuke, upon learning that Makio has not left her room for some time, barged into her quarters to find the place torn and disheveled. Seeing the windows closed and with no other possible exit, he surmised that a demon was in the attic and tried to pursue it. It fled downstairs and Inosuke lost track of its location, with his kimono hampering his acute senses. Meanwhile, Zenitsu used his sense of hearing and detected a young girl crying in a messy and destroyed room. He attempted to comfort her and figure out what happened to her, only to be confronted by Warabihime, the Oiran of the Kyogoku House. However, her sudden appearances and inhuman nature startled Zenitsu, leading him to correctly deduce that she was the demon that they were searching for, and an Upper Rank at that.
