I am a big fan of this novel.
Sadly my Japanese knowledge is non existent, but google translate does a fairly decent job, found some professional translations but they take time to catch up, so I came to read the source material and was not disappointed, I am writing this review to cheer up the author of this series, I hope the chapters keep coming! big fan from Mexico.
I find the premise to be standard so far for an isekai but I love the character development, I like the slow pace of the story that give us time to understand the main character actions and interactions with people of this new world.
I like the complexity of the main character, first he still has his memories and experience from previous life and now he has to adapt to a different era, for any normal human this is a big shock, and second he still has the lingering feelings and memories of the previous soul of his current body (I would say this could be even a bigger shock to deal with), I think this is where many isekais fail and this one shines, most isekais out there try to portray either a very emotionally wimp main character that has overpower powers and if there is a harem it ends up just to be fan service since there is no realistic romantic development and they usually move the plot by brute force (focus on power/leveling real fast and forget character development), guess this is popular with teens and children since 90% of main stream manga I currently read is like this, if not, they go with the superhero MC route, normally he knows it all and always takes correct actions and its perfect which is less annoying than first scenario but end up to be quite boring and generic.
I love when characters are flawed/complex and are handled in a more mature way, I am really liking the MC of this novel, he has many problems to deal with but at the same time he is not acting like a dense child that blushes when he sees a girl, he actually puts some tough into his actions and is explained to us as an audience, its quite refreshing!, only part I dislike is the navy character, it is to big of a cheat and gets in the way of the MC to shine, I would rather see the MC struggle to find the right direction totally by himself or just small help than having such an information cheat that conveniently moves the plot.
I hope the work does not get rushed since its pacing is my favorite part, taking time to explore the struggle and growth of the main character and to see more of the heroines perspective also, and please get rid of navy! or tone it down, is to much of a cheat that actually gets in the way of a much better novel!
