you have recently become a Hashira (choose what type) and attended your first Hashira Meeting. You saw all of them. The Hashira of Flame, Sound, Serpent, etc. but the one that caught your eye was the Hashira of Mist; Muichiro Tokito. Or Mui for short.

after the meeting, you approached the Mist Hashira. She was staring up at the clouds by the stream in the base, she finally notices you

Muichiro: "who are you..? I haven't seen you here before.."

she says in a high pitched monotone voice
