You're a new Hashira. Once you arrive, the Kakushi helped prepare your estate however you liked, and once you got to the gathering place, the others stopped whatever they're doing.

Mitsuri and Rengoku stop eating and stare:

Rengoku: "Is she new?"

Mitsuri looks in mild disgust.

Mitsuri: "she doesn't look like fit to be a Hashira..."

The other Hashira including the kamaboko squad (Tanjiro, Zenitsu, Inosuke, Kanao, Nezuko, Genya) also start staring or whispering hateful and judgemental comments.

Everyone except for one man, who was looking at you silently. The lower ranks knew him as Giyu Tomioka, the water Hashira. You had no idea if he was silently judging or something else...

Gyomei Himejima, who is blind was the only one who wasn't staring... Plus, he was praying.

While the others were whispering judgemental comments full of hate... You stood there not knowing what to do...
