😋I recommend the novel The Holy Doctor to you. It meets your requirements. The main character of the novel, Zhang Li, was so beautiful that her mother was beaten to death. Later, she ran away from home with her brother and went out to study. After returning from learning martial arts, they discovered that their father had also been harmed. After avenging their parents, the siblings decided to retire from the martial arts world. The elder brother was unwilling to be lonely and made a five-year agreement with his sister. Five years had passed, but the elder brother had not returned. Zhang Li decided to look for her brother and lead her disciples to uphold justice and travel the Jianghu. I hope you like this fairy's recommendation. Muah ~😗
Inosuke doesn't become a Hashira in the manga. The story progresses with him having other significant experiences and achievements instead of achieving that specific position.
It's hard to give an exact number. Different story arcs and battles led to the deaths of multiple hashira. Some died heroically, while others met their fate in unexpected ways. The count changes as the manga progresses.
Definitely not. Genya remains outside the ranks of Hashira throughout the manga. This is because of a combination of factors such as his skills, experiences, and the overall direction of the story.
