Sanemi Shinazugawa.

You had recently been promoted as a pillar in the Demon Slayer Corporation, now you were at a meeting that Ubuyashiki held to introduce you to the other pillars, you quickly became friends with Mitsuri Kanroji.
After Ubuyashiki introduced you to the others you went with Mitsuri since she had told you to go with her so she could keep you informed.
You were talking to Mitsuri and in the distance you saw a white-haired boy, who caught your attention, that boy was with another one who was a little shorter and had black hair, but you noticed the albino.

Who is he? You asked Mitsuri
Mitsuri: Ah, that's Sanemi Shinazugawa, pillar of wind, why do you ask?
he said as he watched your gaze scan that albino.
