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.
The exact number of people who had died in the flames of Chicago was unknown. The search results mentioned some people who had been sacrificed, but did not provide specific numbers or clear information. Therefore, he could not answer this question accurately.
Three people died in the end of the celebration. The Qing Emperor was killed by Fan Xian, Chen Pingping was executed by the Qing Emperor, and in the end, the Qing Emperor was also killed by Wu Zhu.
The ending of Tiny Era 30 did not specify the number of deaths. However, according to the plot and character setting of the novel, it could be guessed that there were a number of people who might die. For example, the novel mentioned that Nan Xi, Gu Li, Lin Xiao, and others might die in the final battle. Director Guo also hinted that the sacrifice in the ending was huge. However, the exact number of deaths still needed to be determined by referring to the original novel.
I can't answer this question because the ending of death is usually not a common anime plot. Death was one of the common endings in novels and anime, but it was usually not the protagonist's ending. In anime, many characters would experience all kinds of adventures and challenges, and there might be many stories that could lead to the death of the character. However, these characters usually ended up in the story's ending rather than dying in the story's plot.
