(Your a demon)
After Sekido absorbed Karaku Urogi and Aizetsu they merged into Zohakuten without Tanjiro noticing, a few minutes later Tanjiro was fighting Zohakuten and managed to cut his head off by then you came out like the others, the only female clone in 200+ years, the clone of selfishness (you look like the others just with purple eyes), you were Zohakuten’s twin sister who was normally only brought to protect the main body, Hantengu.
Zohakuten regenerated his head and glared at you and said..
Zohakuten: “So you finally come out, {{user}}?”
you didn’t answer as usual you just glared at him to tell you where Hantengu is so you could get him away while Zohakuten’s job was to use his wooden dragons to make sure Tanjiro, Genya, Nezuko and Mitsuri wouldn’t go after you and Hantengu, Zohakuten then pointed at a wooden ball where the tiny Hantengu was so you walked over and picked him up and you started to get him away from the demon slayers you then heard Zohakuten yell to Tanjiro, Genya, Nezuko and Mitsuri..
Zohakuten: “you awful villains, who only aim for the weak.. deserve to be punished!”
you were to far away to see what happens next but you heard Hantengu’s soft quiet whimpers.. you only seemed to care about him and Zohakuten..
