Despite being told by those around her that she has “no talent for the sword,” Fia, a young girl, still refuses to give up on her dream of becoming a knight. In many works, this would likely mark the beginning of a story about carving out a path through effort and grit, but “Tensei shita Daiseijo wa, Seijo de Aru Koto wo Hitakakusu” immediately leaps far beyond the boundaries of imagination from that point. At the verge of death, what she remembered was the shocking memory of her past life, where she was Serafina, a “Great Saint” who possessed immense power 300 years ago. Moreover, she did not just remember it. Her utterly extraordinary saintly abilities are also completely restored. However, that power, which one would normally rejoice over, was a seed of fear rather than a blessing for Fia. This is because, in her past life, the Demon King's right-hand man had told her, “If you are reborn as a saint, I will kill you.” Thus, while possessing the power of the Great Saint, she begins to walk a dangerous path in life, desperately hiding it to survive.

The fun of Fia lies in the fact that, despite being a “protagonist who hides a secret,” her aptitude for doing so is incredibly low. Even though she fully intends to hide it, if there is an injured person before her eyes, she cannot leave them alone, and if she encounters a dangerous situation, she acts before thinking. Wounds that would take several ordinary saints working together to finally heal, she cures with a casual attitude, thinking, “This is no big deal,” so those around her are naturally thrown into confusion. Yet, she is the only one who genuinely tilts her head in wonder, thinking, “Did I do something strange?” This exquisite disconnect creates a unique atmosphere throughout the entire work. Despite harboring a serious setting that involves life and death, the reason the story does not progress solely with gloominess is largely due to the natural airheadedness and kindness inherent in Fia's very existence.

What makes this work interesting is that it is not a simple reincarnation matchless-hero story. In the 300-years-ago of Fia's memories, saints were beings who fought on the front lines alongside knights. However, in the present day, saints are treated like special guests, and rarely even stand on the front lines. Furthermore, contracts with spirits are no longer made, and the very power of the saints has grown weaker. In other words, Fia is in a state where she alone has been thrown into the modern era while still holding the values and abilities of the past. What is natural to her looks like nothing less than common-sense-breaking superhuman behavior from the perspective of those around her. Moreover, she has almost no awareness of it herself. This dynamic of the “strongest protagonist who thinks they are ordinary” repeatedly brings laughter and surprise to the readers.

Her relationship with the black dragon Zavilia, who appears in the early stages of the story, is also a major highlight. Fia connects in an unexpected way with an existence that should originally be an object of fear. In common works, a contract with the strongest creature is often depicted as a symbol of overwhelming power, but this work does not end there. There is a unique atmosphere in the interactions between Fia and Zavilia, and even in tense scenes, a mysteriously peaceful air flows. I felt that not only the battles and secrets of the story, but also this kind of distance between the characters makes the charm of the work even deeper.

What I felt upon reading “Tensei shita Daiseijo wa, Seijo de Aru Koto wo Hitakakusu” was, “Is a protagonist who is the strongest yet precarious really this interesting?” The appeal of an ordinary strongest protagonist lies in scenes where they understand their own strength and overwhelm those around them. However, in Fia's case, she is not aware of her own abnormality. Because of this, only the readers end up repeatedly retorting in their minds, “No, that is not ordinary.” This feeling is extremely pleasant, making it impossible to stop turning the pages. Furthermore, it is not a work that is just for laughs; the tragedy in her past life, the fear of her life being targeted, and her desire to protect her comrades are also firmly depicted, giving depth to the entire story.

What was more memorable than anything else was Fia's kindness. No matter how much she tries to keep her secret, she reaches out her hand whenever she sees someone who is hurt. Even in situations where she herself might be in danger, she prioritizes helping someone else. That very kindness might be the reason that made her an existence called the “Great Saint.” It was a work where one is drawn to her humanity rather than her strongest abilities. If you read it, you will surely become desperately curious about what form her true identity will almost be exposed in next.
