We need to talk about the potential of renkaza in the entertainment district. Like imagine, just visualize with me here, Kyojuro survives the battle with Akaza and after a couple of months with minor injuries and a brand new eye patch he sees his close friend uzui trying to kidnap the butterfly girls and is able to reason with him, knowing he is distressed about his wives disappearance and offers himself instead along with the original trio. (Therefore we get to see tanjiro and rengoku being like brothers in this au)
Uzui is like unsure but accepts that this might actually work despite rengoku being too old to be accepted as a courtesan (because they usually go for young girls to train so they can be indebted) yet when they put on his kimono and makeup Uzui is like OH SHIT-Kyojuro is fucking gorgeous.
They dont even get halfway down the first street before Kyojuro is crowded by many people begging for him to join their house. Despite being confused Kyojuro accepts with his boisterous enthusiasm. Uzui doesn't let him bring his sword (despite his friends glare) and he is lead to the Tokito house.
Meanwhile Akaza enters the red light district on orders by Muzan to check on Daki and Gyutaro. However he is caught up in a crowd of men who are all beneath a balcony in the Tokito house, as they all whisper about this mysterious new woman known as "Renka." Akaza is not interested in this until he hears that she has strange exotic hair, a vibrant hue of yellow and red. Suddenly Akaza is now interested to see this woman that reminds him of the hashira that was constantly thinking about ever since that battle months ago.
well you can imagine his surprise when the flame hashira himself walks out in the disguise of Renka.
Akaza is even more infatuated then before, and decides right then and then he is going to pay to meet him. He plans to not reveal who he is just yet so he hides in his human disguise and to make it more realistic he buys a snowflake pin as a gift (it subconsciously reminds him of his wife)
Uzui told Kyojuro to decline anyone who is willing to pay for his time but Akaza offers the house so much money they force him to accept. Kyojuro is silently cursing out his friend as he and this mysterious man go up to the rooms, unsure what to do.
Except nothing happens. The man who never says his name is polite and respectful, if only a little pushy by asking him many questions. All they do is talk that night and the man gives him a snowflake pin. In fact Kyojuro thinks him quite handsome, even with the three tattoo lines he has on his forearms.
However when he leaves before dawn, tanjiro alerts Kyojuro that man was a demon by using his super sense of smell. They notify Uzui and Kyojuro receives his sword but they do not think that the demon will go to the same house twice.
They are so wrong.
Akaza comes back the next night and pays for his time AGAIN. By then Tanjiro has left the house to meet with Inosuke and Zenitsu so he is the only slayer in the house. As soon as they get up to the rooms, to Akaza's surprise, pulls out his sword (that he hid in his kimono like the badass he is) and confronts him. Akaza then reveals who he's been the entire time.
Kyojuro knows he cant fight inside the house, or else the innocents can get hurt yet Akaza does not make a move. So instead Kyojuro demands him to tell him where Uzui's wives are. Akaza then informs him that he was not the one that took him, and that he does not attack woman ever. This confuses Kyojuro to no end, and even more so when Akaza tells him about Daki and Gyutaro telling them all their secrets.
They do not end up fighting, because soon they hear a loud explosion (Daki fighting Tanjiro) and Kyojuro is immediately in battle mode. But he is still stuck in an Oiran outfit that restricts his movement because of the shoes. So Akaza like the himbo he is picks up Kyojuro bridal style and launches him over to the site of the explosion. It goes as well as you expect;
Kyojuro: How am I going to get there in time? These clothes are no good for running in my breathing style.
Akaza: Dont worry I got you *Picks him up*
Kyojuro: You could have just taken my shoes off!!??
Now Tanjiro is wondering why the hell uppermoon three is carrying Kyojuro to him more then the fact that Kyojuro cuts the head off of Daki in a breeze a moment later. Uzui joins them, just to see Akaza run off. Kyojuro tells him not to pursue him because Gyutaro is going to show up any minute now.
The battle goes quicker with two hashira, except Kyojuro being informed that his blood art is poision, jumps in the way of Tengen to stop a poisonous blow that was meant for him. The rest of the battle goes exactly the same while Kyojuro is taken out of the picture. When Gyutaro is beheaded he gives one last ditch effort by using his blood art that nearly decimates the entire district. Like Nezuko to Tanjiro, Akaza who was watching the battle the entire time, uses his body to protect Kyojuro from the blast.
Uzui despite having his arm and eye destroyed wonders why the hell an uppermoon that nearly killed his best friend months before is clinging on to him so tightly. He nearly begins another brawl with him, until he realizes that Kyojuro has been poisoned and both begin a truce to figure out how to save him. It goes something like this;
Uzui: Hes going to die! We need to bring kocho here, or a doctor-
Akaza: Is there anything you can do?
Uzui: Do I look like a fucking doctor to you? How about you do something.
Akaza: I can turn him into a demon.
Uzui: I'm going to cut you into little bits you bastard-
Then Nezuko, always being the one to fix things (and carry the entire show) pops up and begins to burn him. Akaza nearly strangles the girl until he realizes its actually burning the poison out of him.
As soon as thats done, Uzui plays a little game of tug of war with Kyojuro as the rope since Akaza refuses to let go of him. Kyojuro wakes up in the middle of this wondering why his torso is in Akazas hand and why Uzui is gripping his legs.
Uzui: Let go of him!
Akaza: No you let go of him!
Kyojuro: I have an idea! How about you both let go of me
Finally free from their grips they are all very tense unsure who is going to attack first. Then, Akaza takes something out of his pocket; the snowflake pin that was torn out of his hair during the battle. He gives it to him, saying to keep it, before running away, just as the sunrise hits.
Uzui gawks at him as Kyojuro puts it back in his hair, and Tanjiro, Inosuke, Zenitsu and Uzui's wives wonder why a demon is courting the flame pillar. Kyojuro still oblivious, questions why his heart feels so fuzzy. Is it the effect of the poison? Either way, he is glad he went on this mission.
