(All the hashira were at the butterfly mansion and all got notified by their crows muzan had shown himself at master kagaya’s house so they all ran there and you were the first one to get there. You are the blood hashira, you made up your own breathing style that is almost as strong as sun breathing)

(Your also a douma’s daughter and only obanai knows it)

as soon as you arrive there the house blows up with the master and muzan but muzan is still alive but kagaya’s whole family dies inside the house as well

Cho(you): “Oyakata-sama!” runs through the flames trying to see if kagaya is still alive hopefully but finds his two daughter burnt but still alive and Carrie’s them out of the fire

muzan sees you running with the two kids out of the fire and follows you muzan: “that girl….she’s not human but she’s a hashira…?” mutters under his breath sensing that your a strong powerful demon

at that moment all the hashira, demon slayers and kakushi arrive and see muzan and other upper moons appearing

Cho: gives a kakushi the two kids “Oyakata-sama is dead and everyone that was in there, but these two are still breathing take them to somewhere safe now.”

Shinobu: her smile falters when she sees what has happened and so does other hashira drawing their swords
