I stumbled upon this series by chance, mostly because I've read lots of light novels by this point and ones I haven't read yet are ones that I've avoided intentionally. Eventually, this showed up in my Recommended feed so I gave it a shot.
Character - 5/10, Plot - 6/10, Setting and Magic - 5/10, Writing - 6/10, Enjoyment - 7/10
If you've read many light novels, you've seen this character before: the extraordinarily bland Japanese salaryman who gets isekai'd to a fantasyland and just wants to live the slow life. And just like so many of these bland characters, he only gets excited about the idea of taking a bath and eating rice. That probably sounds disparaging, but it is what it is. I've seen this character dozens of times. Luckily, our MC, Ryo, has a bit of a competitive drive, so he diligently practices his water magic and develops his physical abilities.
On the topic of plot, there's not much of one here. We only start off with the premise of a salaryman hit by Truck-kun who reincarnates into a fantasy alternate-Earth as a 19-year-old with water magic affinity. The first 50% of the book is just the MC by himself in the forest developing spells, taking baths, and making fish sauce. I'm not even joking. And this covers 20 years of story time, but luckily the MC is blessed with Eternal Youth so he still looks 19. In the Afterward, the author even mentions that this volume was more of a prologue of a prologue, and it sure felt that way at times.
Luckily, about halfway through the book, Ryo finds a person washed up on the shore after a shipwreck and we finally get another character: Abel, the adventurer. At this point, the story finally starts to move and it transitions into one of the tropes I like: a person from the end-game boonies journeys to civilization and doesn't realize how strong they are compared to everyone.
Speaking of magic, I honestly think the power curve got out of hand quickly. The MC developed the ability to cast hundreds of ice lances simultaneously during what seems like the tutorial phase of the story. I don't mind an OP character, but it helps when the magic system at least tries to stay grounded in some sort of universal consistency. I think the power creep will become unsustainable in this series within a couple of volumes at this rate.
The writing, as is often the case with light novel translations, was clean and functional. There weren't any glaring grammar or proofreading errors jumping out at me, but likewise, there was no poetry.
This book will probably be hit-or-miss for people, with the extremely slow start and the bland main character being turnoffs for some readers. I was in the mood for this type of story, and it read quickly, so I was okay with it. But I also reached the end of the book feeling pretty lukewarm.
I will probably read the next volume and see where things go from there.
