Demon Slayer: Became the Stepson of Shuizhu and Was Entangled by Him

[BG+CP Tomioka Giyu+original heroine+according to the original plot line+all members survive+no official matching] A hundred years ago, the Fujiwara family was almost wiped out by Tōmo, the second son of the upper string. It was a water column at that time who sacrificed himself and dragged Tongmo until dawn, so that part of the Fujiwara family could be saved. Later, the Fujiwara family did not forget this kindness and continued to help the Demon Slayer Squad. When Fujiwara Chiyo was 15 years old, Tomioka Giyuu needed to kill a ghost, but the ghost was good at hiding, so Tomioka stayed at the Fujiwara house for a few days, guarding the ghost. During this period, Chiyo secretly learned while Tomioka was training because she asked Tomioka to teach her. Seeing that Chiyo got better and better as she learned, Tomioka taught her for two days. After completing the mission, he gave his blunt Nichirin sword to Chiyo. On Chiyo's 19th birthday, the Fujiwara family was attacked by ghosts and blood. The originally arrogant young lady bent her back. She grew up overnight, her temperament changed, and she learned to keep her true thoughts and emotions in her heart. She participated in the trials of the Demon Slayer Corps and successfully passed the level with Tanjiro. Later, Chiyo acted at the same time as Tanjiro, Nezuko, Zenitsu and Inosuke. She carefully molded herself into a gentle, reliable "Sister Chiyo" who always had a warm smile on her face and took good care of her younger brothers. This disguise was almost perfect until Tanjiro, who had a keen sense of smell, revealed the truth late one night: "Miss Fujiwara's breath is full of sadness and anger... Why are you always smiling?"
