As the name suggests, Katarina has reincarnated in a game where she is a villainess and will experience destruction should any of the game scenarios come true. Determined to prevent this she starts working on countermeasures. Problem is, she is kind of an airhead, so the countermeasures she come up with aren't realistically viable. However, she has a bubbly, cheerful and carefree nature, different from the villain in the game scenario who was cruel and will make the heroine suffer. Unknowingly she starts befriending everyone and they all get caught up in her pace as a result.
The manga can feel a bit rushed at times, with many details omitted or watered down compared to the novel, but of course this is a common occurrence with all adaptions and in this case doesn't detract from the enjoyment that can be gained from this manga. Most of the story is in Katarina's' perspective but we also witness it from other characters point of view and we can clearly see how Katarina has influenced their lives for the better (Which is very sweet and wholesome).
The art is good and this story is comparatively different from other Isekai genres which is quite refreshing. Even when there are many similar stories of the "Reincarnated as a villainess" trope, this one still stands out from the rest. Recommended for anyone looking for some good laughs.
