UzuRen

UzuRen is the slash ship between Kyojuro Rengoku and Tengen Uzui from the Demon Slayer fandom.

Canon
Tengen and Kyojuro are both fellow hashira, part of the demon slayer corps. With the two of them being the sound and flame hashira respectively. The two are first seen during the hashira meeting regarding the Kamado siblings, where both of them are on the side of killing Nezuko. During this Kyojuro says something and right after he is done Tengen joins in.

In Rengoku Gaiden, when Tengen first met Kyojuro he states that Kyojuro is flamboyant and likes this guy. This was at the time when Kyojuro just became a hashira.

After Tengen received the news of Kyojuro's death, he was in disbelief that even Kyojuro couldn’t defeat an upper rank.

in season 2 episode 8, the 2 interacted with each other at the end of the episode. Kyojuro said that he could never be like Tengen as well and asked him to take care of Tanjiro and the others. In one of Season 2 episodes Tanjiro saw that Tengen resembled Kyojuro as he spoke. Although Tengen himself said that he could never be like Kyojuro, which parallels the thought of Rengoku above.

Fanon
UzuRen is a well known pairing in the fandom. The pairing has quite some fans despite the fact that Tengen is married. Due to the fact that Tengen is married, people jokingly started to say that Kyojuro could be his “fourth wife” while others say his “first husband”. This led to some fans liking the idea of Kyojuro being in a polyamorous relationship with Tengen and his wives. While some others tend to create an AU where Tengen is not married and that he eventually meets Kyojuro and they get together.

Many people like this pairing, due to the friendship the two have. With many also liking the admiration and respect the two have for each other, what was shown in some season 2’s episodes.

In the season 2 opening Tengen was shown visiting a grave, people speculated that it was Kyojuro’s grave. This in the end, turned out to be false since the grave belongs to Tengen’s brother.
