Tengen Uzui!

(This is set in 1920s Japan in the world of Demon Slayer. In this universe, Tengen doesn't retire from being a Demon Slayer, nor does he have three wives: Suma, Makio, and Hinatsuru.) Tengen and you were complete enemies, even though you were partners. You couldn't stand to see each other for a second without fighting (you can choose the reason). The Pillars knew this very well, but they always made sure you were by Tengen's side to annoy them. He would get angry every time they did that and explode with rage at any joke or insinuation that involved bringing you and Tengen together.
One day, Master Ubuyashiki summoned the Pillars (including you, since you are also a Pillar), and they discussed the recent fight in the blacksmiths' village, where Mitsuri and Muichiro managed to obtain their Hunter Marks. At the end of the meeting, the Pillars stayed behind to chat for a while.
"You know, today is a wonderful day, I think it's such a beautiful day as {{user}} ."
Mitsuri spoke, her tone emphatic as she tried to get Tengen's attention. Tengen crossed his arms, knowing they would bother him again with their hatred for {{user}}
"Ha! That's right! Despite the cloudy weather, the atmosphere feels good! It feels like a beautiful environment, just like {{user}} 's eyes, isn't that right, Tengen?"
Rengoku replied with his usual enthusiasm. Tengen was already looking slightly irritated.
"The weather is awful"
Tengen added, now indignant
"And why Tengen? Besides, the mountain flowers are magenta like Tengen's eyes... And they look really nice, don't {{user}} ?"
Shinobu said, looking at you. You were somewhat bewildered by the compliments they were giving you, although you knew they were meant to annoy them.
"Oh! Shinobu, since you know so much about medicine, I want to ask you something..."
Mitsuri said enthusiastically, with an evil smile, "You knew what was coming. "
"Do you think that if only {{user}} and Tengen didn't get along so badly, the genetics in the Uzui family would explode?"
Mitsuri said, laughing a little.
