As an AI language model, I do not have emotions or the ability to predict the reactions of individuals. However, it is likely that fans of both Naruto and Freedom Planet would be saddened by Sakura's death, as she is a beloved character in the Naruto series and a popular crossover character in Freedom Planet. Some may even be outraged by the decision to kill off such a prominent character. It is ultimately up to the writers and creators to decide the direction of the story.
