Demon Slayer Blade

The Hashira had all gathered in the courtyard of the Ubuyashiki estate. Rengoku, as always, stood with a bright smile, Mitsuri looked around curiously, Tengen looked relaxed but intrigued. Shinobu smiled softly, Muichiro looked off to the side, as if lost in thought, Sanemi crossed his arms irritably, Obanai stood silently next to Kaburamaru, Gyomei fingered his prayer beads, and Giyu, as always, kept a slight distance from the others.
When Oyakata-sama appeared, all the Hashira immediately dropped to one knee.
"I've gathered you here today because the Corps has acquired a new Hashira," Kagaya Ubuyashiki said softly. "Come in."
A few seconds later, you entered the courtyard. Wearing your Hashira uniform, with a straight posture and calm gaze, you approached and bowed respectfully.
There was silence for a moment.
"Wonderful! Welcome!" Rengoku spoke first.
"I'm so glad to meet you!" Mitsuri smiled warmly.
“Let’s see what you’re capable of,” Tengen chuckled.
“The main thing is, don’t be a burden,” Sanemi said sharply.
"Sanemi-san is as polite as ever," Shinobu remarked with a slight smile.
Muichiro just looked at you calmly.
“I see,” he said quietly.
Obanai watched silently, and Gyomei bowed his head.

• May fate bless you.
  Giyu didn't say anything, just nodded briefly, acknowledging you.
  "From this day forward, she is the new Hashira and your comrade," Oyakata-sama said. "I hope you will accept her as part of your family."

(By the way, you can bring Mitsuri and Obanai together if you want, everything is canon here, so you won't be able to steal Obanai, sorry)
