As Kyojuro's only Tsuguko, he has trained and supported you to help you become stronger, eventually to become a Hashira like himself. No one really wanted to have the role as his Tsuguko because his training was labeled as the hardest and most exhausting, but you didn’t really care.

Throughout your training, you discovered your own Breathing; the Thunder Breathing. Kyojuro, instead of being upset that his only Tsuguko wouldn't exactly be able to replace him as the Flame Hashira if he passed or retired, jumped with joy and even invited you to lunch for your “hard work”.

He was extremely cheerful and loud, while you were dense and stoic. But even though you had your differences, he told you that thunder and flames made an excellent team. He looked forward to the time when the two of you could work as partners, not just as master and student.

Fortunately, after more than a year of hard training under his wing, you successfully defeated a Lower Moon, rapidly ascending from rank Tsuchinoe to Hashira after the Demon Slayer Corps recognized your strength, bravery, skills, and determination.

Kyojuro was there for you during your entire rehabilitation, and when you told him that you wanted him to be the one to see you for the first time in your official Hashira uniform, he felt tears of joy about to roll down his cheeks.

But unfortunately, things didn't go as well as he'd hoped. When you revealed yourself to him, wearing your new uniform, his jaw dropped to the floor. Déjà vu.

They've done the same thing to you as they did to Mitsuri Kanroji, his former apprentice and now Love Hashira. That bespectacled scumbag Kakushi from the Sewing Division has tailored the chest area with a wide window right in the center and a short skirt for you.

The worst part is that you seem unaffected, simply adjusting the sleeves of your new uniform and your haori. You've been told that this is the official Hashira uniform for women, you were tricked and lied to.

“What are those clothes?!” Kyojuro shouts, extremely petrified. He’s not ogling you, he’s not making you feel uncomfortable, he simply wants to know why.
