I felt it important to point out some major faults in other reviews that incorrectly state what the story/narrative is doing.

Since no one seems willing to point to specifics, allow me. Chapter 19 is the one that seems to trip people up the most. Relative to the series (over 100 chapters), is a single page, maybe two (incredibly low number of word count). It is not an 'ark'

Mild Spoilers. In the same vein of many other-world-fantasy stories, this one has the harem tag. The part people raged at can be... more>> found in chapter 11 of the manga. Snow is the Main Character's fiancee, who he stays loyal to (any mention of NTR is devoid of an understanding of what NTR is, apparently). The MC strikes out on his own to be a big bad adventurer. He gets tricked by his first group, robbed, and sold into s*avery (its actually quite comical, though the party that tricked him did break a couple fingers). The family that buys him has a daughter (remember? Harem?) who he thinks is super cute, making her someone you want to protect like a little sister. She even calls him big brother and later, calls Snow big sister with lots of girl only implied agreement stuff in the background). This 2nd girl was afraid of men for the most part and is a shut-in vampire girl, so the overbearing dad made the MC dress up like a girl to ease the shock of her birthday present, which amounted to a polite kid closer to her age who's blood can be drank on occasion. Later, Snow (his childhood friend, the fiance) becomes great friends with our vampire girl and appears to be pushing her to become the 2nd wife with the MC being the most reluctant one in the lot (which, again, isn't NTR).

SO!!! Reviews will be reviews, but I felt compelled to at least comment on the incorrect assessment. Hate it, Love it, but Ol Ventus will come a smacking if you start spewing falsehoods. <<less

I have to echo the statements that the story was interesting at first but it became predictable and bland later on as it focused on harem elements. The story would have stayed a good read if only the author retained the tendency of the MC to focus on the tasks at hand as shown in the earlier chapters. He wanted something done, he would concentrate on that alone.

As for the romance just the MC and the first heroine being paired was more than enough. But like SAO, the element of... more>> romance was destroyed completely by the incomprehensible desire to create a character who would surround himself with women and have a raging boner towards said women.

We know you're an undesirable person in life who died a virgin. Get over it. Having yourself being surrounded by women who would love you for no reason is not very compelling to hear. Romance as written by those who don't even know it in the first place.

The appeal of the Isekai genre or any story that involves the protagonist/s being transported to another world is to see how a person from our world would react and to see what they will do to survive. To see how they do what they can to make the best out of the situation with nothing more than what they have.

The essence of a story is to create conflict so that a protagonist will rise to up the challenge. They may or may not win but that what it makes it interesting in the first place. Failure to do that, takes the life out of a story. Risk and reward, simple words that would mean so much if properly incorporated into story telling.

This story got that element in the beginning but failed to do so in the succeeding chapters. Due to its nature as a webnovel I may perhaps lay the blame on the readers who have probably hijacked the story by demanding the character be tailored to their desires and make it easier for them to insert themselves as the character.

I've seen this happen on many stories published online. Though if it's true, it is also failure on the author's part to stay true to the story he wanted to tell. The story had promise and potential that was ruthlessly squandered by turning into yet another mass-produced piece of low-quality literature. <<less

I have read the web novel (translated and Japanese) until the end of volume 9 and so far its interesting to me. There’s some long explanation of history of firearms so if you don’t like it you might find it boring. The s*ave part might look dark but after the MC meet his second wife and try his best during that part it will become more interesting. Might be some different with the LN though. So far as I read... he gain more fame, money and more wife, develop grenade launcher, machine gun, landmines etc, beat twin dragon, basilisk, save kingdom, become noble and so on. Since he is not really op for me and not really interesting I give 3.5/5.

At first, this story had a lot of ups and downs. Start off dark, then light hearted, then dark, then light hearted....

But, by now things have somewhat stabilized and I don't know if thats a good thing or not.

... more>>

His freind's suicide due to bullying and then his murder was very grim, but then we get treated to a second childhood and MC is early genius to invent guns and whatnot. He even gets engaged to his new childhood friend. Then, he's betrayed robbed and sold into s*avery. However thats okay as they aren't that bad.


The author also likes to use gags where what you were expecting doesn't happen... Its kinda like making the audience spit take as they come out of nowhere and are usually based on a quickly cleaned up misunderstanding.


Snow (his childhood friend from the orphanage) and him are about to turn too old to stay in the orphanage and must leave. Before they do 12 year old Snow summons up her courage and confesses to the MC "Please make me your s*x s*ave!" Well, they clear that up and MC marries her instead.


Well, anyway, the major good point of this story is that its funny interactions between characters. They are truly cute... when they happen. When action happens everyone's character except for MC seems to disappear except for a few 'and that person did something' over there mentions.

Beyond that the plot is as generic as can be... ancient evil defeated long ago... boy from earth reborn in the fantasy one... vague chosen one prophecy... cute girl harem... Its all been done before, but its a shame that the first chunk of the story which focused on slice of life ordinary every day struggles was a strength this story had greatly. But it turns away from that because hey, a world ending evil needs to happen.

This story has already gotten a manga about it (although the artist made the girls' blushing look ugly as h*ll), and I expect an anime sometimes soon. That is simply on the basis of how already anime series-like the plot structure seems to be. Of course how Smartphone got an anime before this one I won't know. <<less

Queues typically not a bad novel with a hero fan guns. Places of interest, and not bad, but there are whole arch outright boredom. Not only the text, chapter reads very quickly and easily, the style of narration is very simple and naive. Geroy places not far to the extreme, not to say that the hero is in love potions in their wives and romance lame. There are not pretentious humor, the story is weak and the potential is not great. I hope the author does not get lost in... more>> the future, the few advantages, that is. Otherwise, the product will be a complete failure. Rated 3 star and 6 tenths of a star, but this is the ceiling for such stories. <<less

Great research done on weaponry. Story-wise seems very contrived. The author go to great lengths to engineer situations involving modern firearms and make them excel. Magics and magicians are made into sacrificial lambs to the cold hard sniper rifle.

More could be done to make it less contrived.

Main Character comes from a modern world into a fantasy world. Alright cool, what can he do you ask.. Make guns.
We follow the MC as he grows up and gains the attention of many people.

The story and premise is unique in it's own way, the only thing I believe is lacklust is the fact that it feels rushed in the romance department. But that's another matter. The translations is going at a decent pace so I'll just a say give it a try if you like these "Modern world... more>> person transported after death to another world" type story with its own twist. <<less
