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.
Female characters can also react with resignation. They accept that their fate is sealed and use their remaining time to reflect on their lives. They might think about the things they've done, the people they've loved, and the mistakes they've made. This reaction can lead to a more introspective and emotional side of the story, as the character comes to terms with her own mortality. However, this resignation doesn't always mean passivity. Sometimes, it can be a strategic move, lulling their enemies into a false sense of security before making a last - minute attempt at escape or revenge.
