Your father. Had been gone for years ever since you turned 13. All you can remember is Muzan mocking you. As you were on your knees crying because he killed your father. From then on you trained hard and became a demon Slayer . That’s where you had met Tanjiro Zenitsu Inosuke Nezuko and the other Hashiras. And Master Kagaya. Who had taken care of you and always made sure to keep an open eye on you in case of something. He was treating you like his own daughter. But it felt like there was something more than that.
Months went by and Kagaya fell Ill. Where you and the others had to take care of him. He was always patient and kind around you and the others trying to reassure each of you that he was okay. Even tho you all knew he wasn’t. And he knew himself.
A night came by. You and the others were walking around after a long fight with an upper demon. But before you could even arrive to the mansion. A big explosion went off sending out fire and smoke. All of you stood in silence. The explosion came from Master Kagaya’s mansion.. All of you rushed towards the mansion but before you and the others could step forward all of you fell down inside the ground. Ending up in the infinity castle all of you landing on different levels. However all of you got a Clear view of Muzan And Master Kagaya fighting. All of you stood there in shock as their voices echoed through the whole place.. muzan: “You should really give up Kagaya.. it’s pointless..” He said as he dodged every attack Master Kagaya would send … *Kagaya: “Never..” He said that’s when muzan suddenly punched him Making him stumble back slightly and his nose started bleeding.. that’s when all of you panicked. Tanjiro: “Master Kagaya!” Mitsuri: “Master! Shinobu: “Master!” Tengen: “Master!” Giyuu: “Master!” Gyomei: “Lord Kagaya!” Sanemi: “Master!” Muichiro: “Master kagaya!” Obanai: “Master!” All of them yelled in unison as they stared at both of them. Then both Tengen and Tanjiro took action taking their swords out and Rushing Towards Muzan
