The fem gymnastics reader could be curious. Despite the differences in the two areas, she may want to explore this new type of fanfiction. Maybe she'll be interested in how the writers create such a spooky atmosphere and unique characters in creepypasta fanfiction.
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.
She could be fascinated. Despite the contrast, the unique and often complex storytelling in creepypasta might draw her in. She might start to analyze how the authors create such an intense atmosphere, which could be different from any analysis she's done in relation to gymnastics, but still engaging in its own way.
