What if Tanjiro and Nezuko had another sibling that survived? Nezuko's Identical Twin Sister, Kamado Misaki. 

Misaki decides to convince her older brother Tanjiro to help with selling coal down at the village to make the process faster as winter has arrived and it gets very cold in the mountains during winter. 

What the 2 siblings didn't expect to find when arriving home the next morning after Saburo convinced them to stay the night, was to find their entire family slaughtered leaving them and Nezuko, Misaki's twin sister, alive. 

Nezuko having turned into a demon catches the other 2 Kamado's off guard. 

Misaki and Tanjiro will do everything in their power to bring their sister back and turn her human again, even if that path brings death and hardships to them, even so they don't let that set them back, they're Kamado's after all. 

Making new friends and meeting future lovers in the process, is all apart of their journey and put an end to the demon kind.

Sakura Hirai is a 20 year old girl who lives down the mountain from the Kamado family where she has looked after their children for years after the Father of the Kamado family, Tanjuro fell ill. Sakura's responsibilities consisted of looking after the younger children and helping the older children, Tanjiro and Nezuko descend the mountain day after day to go work in the village. As the village's doctor, Sakura was always busy and is very skilled in care. After a fateful night where Sakura and Tanjiro didn't return to the family's cabin, Tanjiro, the eldest son of the Kamado family, comes home to find his entire family slaughtered. Tanjiro, in a complete panic checks on the oldest sister first, Nezuko, who is still warm and rushes her down the mountain to see Sakura who seems calm about the whole situation. After checking Nezuko's injuries, the three return to the household where Sakura and Tanjiro bury the family's corpses before heading off. But Nezuko is not herself anymore as she starts to turn into a bloodthirsty rampaging demon on the back of her loving brother and threatens to attack, Sakura turns to the only thing she knows best, protecting those she holds close.
