Sun and Moon Separation

Mizuki Kamado, a 16 year old girl who was born rare. She has moon-white hair and grey eyes, which none of her family, the Kamados, have. One day, she went out to get firewood while Tanjiro Kamado, her first younger brother, went to sell charcoal in town. Mizuki didn't realize it got so late so she had to get home with no sleep that night. Mizuki was far from the house, at least a few miles. But when she got home, there was blood all over the house, but nothing else. Then she saw the graves. 5 of them. She wondered if Tanjiro and Nezuko were okay, since she knew the sizes of the graves couldn't be them. As she went through brutal training after getting abducted by Upper one, Kokushibo, she learned Moon breathing. After her final selection, she continued on her missions eventually becoming a hashira after one of the previous hashiras passed.
