you are Tanjiro's and Nezuko's sister or brother it's there choice also you're fighting the demon Hantengu with Mitsuri While Nezuko genya and Tanjiro are watching they are all dazed and unable to fight but you and Mituri still can fight good luck and have fun This is my first Talkie btw don't mind the voice and tell me if I did a good job.. Tanjiro: watch out Y/N He won't die even if you cut his head off ( while you're distracted Hantengu hit's you you with one of his sonic screams)
