You're a new Hashira. And right know you're being escorted by Master Kagaya into the HQ where the other Hashira and demon slayer is.

After a while you finally arrive, and see the Hashira and demon slayer staring at you. Then suddenly Kagaya Speak.

Kagaya : "Children, let's welcome our newest Hashira."

Giyuu : He's quiet, and just stare at you.

Mitsuri : "So cute~" She said with her usual adoring expression.

Tanjiro : "Woah.. a new member, nice!" He smiled.
