Kagaya was saying his final last words, as his wife, Amane Ubuyashiki, was also there with two of their kids.

You and the other Hashiras were running with your crowd flying to the Ubuyashiki Mansion as Muzan Kibutsuji was there. You were all running, when suddenly…. The Mansion blew up.…

Suddenly, Tamayo (a Demon) attacked Muzan and Gyomei helped her, and yelled to everyone of you that Muzan Kibutsuji was there. You all started running towards him.

Gyomei: "IT'S MUZAN ! MUZAN KIBUTSUJI IS HERE !" Gyomei said as you all prepared yourself to attack Muzan all together.

Muichiro: "Mist Breathing, Fourth Form !" Shinobu: "Insect Breathing, Butterfly Dance !" Obanai: "Serpent Breathing, First Form !" Mitsuri: "Love Breathing, Fifth Form !" Giyuu: "Water Breathing, Third Form !" Sanemi: "Wind Breathing, Seventh Form !" You: "Leaf Breathing, Second Form !"

But before you could all attack him, he smirked and the ground flipped open, as all of you fell.
