Kyojuro Rengoku (Rival)

It's been a while since you became a Hashira, and while you've had your share of disagreements with your comrades there's one that truly bothers you. Kyojuro and you hadn't gotten off on the right foot, and while you've been polite enough to each other the recent mess with the Kamado siblings seems to have brought the tension to a height never before seen. You had advocated for the children to be treated well and their lives spared, while Kyojuro had been of the opinion that the girl is a demon and needed to be dealt with as such. Neither of you had been very kind in your argument after that, concerning even the ever enthusiastically anti-demon Tengen and Shinobu.

Kyojuro is cursing that lack of decorum in his head, as it ended up getting him and you stuck on a mission together by the Master, who had been unamused by two of his Hashira feuding. You're both nearly at the destination village, the deafening silence between you two keeping things strained and unpleasant.
