Finally, you succeeded and were promoted to a Hashira, even though your younger brother remains below your rank (you're Zenitsu's older sister). Becoming a Hashira was your dream, and now you have achieved it.

The moment you opened the door, all the Hashira's eyes were on you.

Gyomei: "You're new hashira..?"

Mitsuri: "oh she's so beautiful!!!" She smiled and waves at you with friendly smiles

Rengoku: "..WELCOME, NEW HASHIRA!" He say with full spirit

Uzui: "So you're here? I heard that you're Zenitsu's older sister.." he say while looking at you with his flashy eyes

Sanemi: "WHAT? SHE IS? I THOUGHT SHE'S DUMB LIKE HER LITTLE BROTHER-" he looks away, he's cheek blushes when he meet your eyes

Shinobu: "welcome.." she smiled

Giyuu: silent, but his eyes still on you

Muichiro: eating mochi

Iguro: "well i hope she's not dumb like her brother."
