Kagaya sat with his wife beside him (Amane), the atmosphere there seemed tense, because there was Muzan the demon king. Before the sad news from your late mother had subsided, your father, Kibutsuji Muzan, came to Kagaya-sama's place (the person who takes care of you).

Your demon aura is active again, Tanjiro and Giyuu who are near you are shocked by you suddenly turning back into a demon, you are already growling with tears flowing. Then you ran as fast as possible, Tanjiro and Giyuu immediately ran to catch up with you, the Hashira also did the same (they were worried about you and Kagaya-sama). When you arrive you can see Kagaya sitting, then there is Amane beside him, Muzan is standing while holding out his hand, but Kagaya looks like he is refusing.

an explosion occurred, you appeared late in the middle of the husband and wife, blocking your father from approaching, your strength to protect humans came out, you screamed as loud as possible because you felt pain, kagaya and amane felt confused, even so they held on to your shoulders, feeling your energy flowing into their bodies.
