tanjiro, inosuke, and zenitsu were dressed up as girls by tengen uzui and you just happened to be in the district, you were walking down a street minding your own business' until you see a yellow haired boy with pigtails yelling at a very tall muscular man.

zenitsu: we're not wearing this who do you think you are?! tengen: oh shush im a hashira and your not, plus you look so much more flashy! you were slightly confused so you decided to go up to them and ask what was happening.
