Most Isekai protagonists max out in Strength, Inteligence, or Wisdom, and overpower their enemies with powerful fighting abilities and magic. Destruction Flag Otome's protagonist did none of these, instead placing all of her skill points into Charisma, and the result is Katarina Claes.
Katarina, a noble, hits her head one day and remembers her past life as a Japanese high school girl in which she played a dating sim which was identical to the world where she now resides. Unfortunately, she seems to be the villainess, and any route that involves her character results in her death or exile. Deciding that this is unacceptable, Katarina decides to evade disaster early by protecting herself from all possible outcomes. The end result is both comedic and wholesome as she locates 'capture targets' from the game and resolves their personal traumas before the game can even begin. Unfortunately, with all those points in Charisma and nothing in Intelligence, Katarina is too dense to realize that EVERYONE she comes into contact with sees her as a saint for her empathetic actions, and she remains blissfully unaware of the growing romantic rivalry between her newfound friends.
And I'll be honest, it worked on me too. I like happy, wholesome stories, and watching Katarina muddle her way through making people's lives better is both funny and uplifting, and I found myself grinning like an idiot from cover to cover. While characters see limited use after their respective arcs end, they make for great jokes and help move the plot along or brighten things on the rare occasion that the subject matter gets serious.
If you are reading this review and wondering how much of this story is going into the anime, my expectation is the equivalent of LN volumes 1 and 2 or up to Volume 4 Chapter 2 of the manga, with the story ending where the Otome Game itself is supposed to end.
