RenKaza

AkaKyo is the slash ship between Kyojuro Rengoku and Akaza from the Demon Slayer fandom.

Kyojuro vs Akaza
Akaza and Kyojuro are enemies who met after the battle where Rengoku, Tanjiro Kamado, Inosuke Hashibira and Zenitsu Agatsuma were all successful in defeating Enmu, who had fused his entire body with a train full of sleeping passengers that were put out cold by the Demon. Inosuke and Tanjiro searched for the neck of the Demon. While Rengoku Nezuko and Zenitsu protected the passengers.

Though the fight was difficult, the Demon Slayers were able to defeat the Demon. Also thanks to Rengoku's incredible strength not a single passenger were killed by Enmu. But Tanjiro Nezuko and Zenitsu are all spent. Tanjiro was badly injured being flung off the train after it crashed and already had a severe stomach wound given to him by the conductor of the train. Zenitsu had a head injury given to him after the train crash, holding Nezuko and another passenger in his arms. Nezuko also used up all of her strength protecting the passengers.

Rengoku commends Tanjiro and acknowledges him for mastering Total Conentration Breathing: Constant: and tells him that he closer to becoming a Hashira (not that close though). He quickly instructs Tanjiro on how he can stop the bleeding that's coming from his wound. Not too long afterward, Akaza arrives. Tanjiro becomes shocked and realizes that he is Upper Rank Three,

Kyojuro quickly unleashes the Flame Breathing, Second Form: Rising Scorching Sun, which cuts the iAkaza's arm in half and causes him to leap backwards, away from Kyojuro and the others.

Akaza quickly reassembles his arm and compliments Kyojuro's Nichirin Blade while licking the blood off his own arm, whom the latter then asks him why would he target a wounded person instead of him. Akaza says that he just thought Tanjiro would get in the way of their little "chit chat", to which he responds by asking if they had something to talk about and saying that he despises him despite it being their first time meeting. As he smiles, Akaza says that he hates weak people too and that they disgust him. Kyojuro responds that the two appear to have practically complete opposite moral values, and Akaza then asks if Kyojuro would like to become a Demon himself.

Rengoku obviously refuses the offer and says that he values human life. He tells Akaza that no matter what he says he will not become a Demon. The two then eventually result in a battle
