The novel has received numerous negative reviews due to extensive information dumps, particularly in the early chapters, which can lead readers to lose interest and abandon it. Critics acknowledge that these dumps are essential to provide context and understanding but also point out that they can be overwhelming. The author addresses this issue somewhat later in the book, reducing the frequency in the light novels.
While some argue that info-dumps are necessary for comprehension, examples given show that they serve to explain complex concepts like the challenges faced with managing 5,000 refugees, the strategic benefits of horseback combat, and the lack of scientific advancements. These details help ground the characters' actions and decisions in a realistic context for readers familiar with a peaceful society.
It's possible that the author could improve info-dumps through more subtle storytelling techniques, known as "showing rather than telling." However, for those who actively seek to skip these segments, the novel offers a compelling narrative about a protagonist struggling against demonic invasion, delving into politics, intrigue, strategy, logistics, and action.
What sets this story apart is its start during the actual game (invasion), bypassing the typical school life and training arc found in other reincarnation stories. This allows the story to quickly progress to the main storyline without unnecessary detours.
The only potential downside, for some readers, is the limited exploration of the protagonist's relationship with the hero, which is covered in just one chapter. Opinions on this vary, as some might find it insufficient in conveying emotional depth, while others see it as a means to streamline the plot.
In summary, while the novel has issues with info-dumps, it offers an engaging and fast-paced adventure that appeals to those willing to overlook or skim past these sections. The unique starting point and focus on the main storyline make it stand out among similar narratives.
