There's nothing particularly terrible about this story, it is just rather dull. Everything goes fairly smoothly for the protagonist and nothing really interesting ever occurs. The MC has no personality and is just as dull as the plot has been so far. The author tends to glaze over a lot of stuff in the novel and it just gives an impression of laziness.

You might not enjoy it if you don't get pleasure from RPG wish fulfillment, but if you do then this is for you. The MC is easygoing but ruthless. The plot isn't exactly deep but there have been a steady stream of interesting situations and (for me, at least) this story is both enjoyable and promising. It could be better, but it could also be much, MUCH worse.

I'm really glad it doesn't devolve into the asinine, plot-less mess that most JP RPG stories tend to become after the first 10-20... more>> or so chapters. <<less

..... it's a Slice of Life, alright. If you can't endure reading Isekai Smartphone, Lilianne, or DesuMachi, then bail out from this page right now; you won't like it. Hell, you might even give it bad rating because it's completely plotless; which is the main characteristic of Slice of Life genre.

The earlier chapters are short yet it steadily getting longer. I guess the author is improving in his own way. **shrug**

It's a story about a young man who got hit by truck blablabla template isekai plot, then realized he... more>> has a good stealth ability in the other world. To be honest, he's not really an assassin (lol) ; it just he loves to sneak attack his enemy and behead them, which give him a cool nickname, Headhunter (or it should be Neckhunter but that sounds weird)

The main point of this story is... nothing. Yep, nothing. It's a pure Slice of Life, so what did you expect? The only notable point is... Sari is cute. She's justice. Period. <<less

The pacing is a little bit slow, theres some odd choices with the names but overall its worth the read. Also it has lots of Loli's, what to lose? Not the best but not the worst, quite enjoyable.

Not the worst, but still, poorly written. Chapters are short and simple, MC goes through his new life like a video game - everything is simple and easy. To me, this reads like a children's story - there is no sense of reality (for eg.: MC's first day in the new world, he finds a cave and sleeps soundly till the next day - no wariness for danger, no description of what he used to sleep or how. I suppose the floor of the cave is made of foam and... more>> there's air conditioning, lol)

Worst of all, MC sounds like an idiot when he's talking to himself while enjoying his video game life. ("Hey, I guess I'll try roasting this rabbit I just killed, without skinning the fur or cleaning the blood and innards out. Wow it tastes delicious! I'm in a children's book!!)

Don't read this. <<less

... what can I say, this novel is dull.

Character development and deep plot are nowhere to be found. Story is just basically male lead being op as hell and everyone else are being weak and cliched 2 dimensional mobs, and also the plot armor is strong in this novel.

Personally I liked few of the first chapter and thought that it was fun and interesting, but it soon became so dull and that made me drop it.

This novel is perhaps good read for people who have not read much novels before... more>> it, but those who have probably agree with my opinion.

Overall: not the worst, but not good either. <<less

The chapter/s are too short and wasting the pages with a describe of how he ate.


The title said; assassin, but he also can use magic... (he got it just by just thinking of it) same as item box


The demerits (i guess) ;

  • MC keeps open and check his status, every single time...
  • Got extreme cheat
  • Gain title/s easily
  • The story wasn't elaborate in explanation
  • Rather a dull story

Not bad, but nothing outstanding. MC is the Gary Stu SI type, and is a bit of a pedophile, with a thing for 10 year old girls. I say "a bit" because his strike zone includes beauties in their twenties as well as the "loli babas". I don't recall any actual s*x so far, but the sexual undertone is sometimes pretty thick - unfortunately, this includes the pre-pubescent girls.

I give this novel a 2-2.5.

It’s a very generic isekai novel that suffers from what most average novels suffer from, i.e bland characters.

If it was just that then it would deserve a very average 3.0 score, but the MC unfortunately brings it down a point.

... more>> *spoiler*

The MC is literally able to get any magic just my thinking about it. He wanted fire magic to cook some food, therefore he instantly made a fireball. He found it burdensome to have to carry all his stuff, so he conveniently gets an Item Box skill.

The whole point is, is that he has been a NEET for 7 years, but when he fights battles that can endanger his life he never even thinks about using magic. He doesn’t even think about trying to acquire/train in any new magic to help in fighting. It just makes me frustrated when he can just think of a magic and acquire it, but decides to use his dagger to decapitate monsters. I could understand him only using this means of killing if he had combat training in his previous life, but the MC has spent 7 years being a NEET that rarely left the house.

His stealth ability can hide the casting of spells, so that’s not a reason to only use melee.

Okay, I’m done ranting. After binging 60 chapters I gad to get this all off my chest. <<less

It's interesting, but it's like, s*upid. I'm not being a hater, cause I do like this series, it's just, the background, the pacing, and even the characters around the MC act too, "conveniently". If you're looking for a casual read, then this is good. We have a generic overpowered MC. It truly is perfect for a casual read, cause there's no complicated stuff, no confusing situations, and there's no harem (yet). This however, is why it get's four stars, I like it, but it's too generic for me.... more>>

I still like it

Many things I could say about this. Yes, it is slow pace isekai wish fulfillment, but overall it's mediocre for even that type of novel. Also, his appraisal of others status when compared to his own and the related writing makes my heart hurt.

A lazy writer indeed. This novel has been making me to work my sh*t just to read the damn story. So dull, and feels like an elementary kid was writing a story for homework. And who the hell will proudly telling anybody that you're an assassin? Are you really going for that type of settings? Don't waste for this shit.

I like OP protagonists and fast paced stories like this but I don't really like the idea that the female lead is a 10 year old kid. The protagonist is 25 years old! Are you freaking serious? Is the author a borderline pedo or a total pedo? Geez.

Gave it 3 stars for now because I like OP MCs and that's he's not hiding his skills. I'm still on c53 and things about his love life might still take a few turns and hope he gets a lady fitting for his... more>> age. But if it's final that the kid is the target, might edit and give a lower review. <<less

story : 3/5

story writing skill : 2/5

characters : 2/5

world building : 0/5

logic : can't be found xD

translation 2.5/5

The story is about a baby-faced 25 yo NEET, dying thanks to truck-kun (or a relative of truck-kun I guess) and being sent to another world of sword and magic with a cheat thanks to God.

Now that a quick summary was made, let's talk about the pros and cons of this novel.

pros :

  • it's not heavy on the mind to read. More of a slice of life since it's a day to day story.
  • cute lolis
cons :

  • the writing style is... middle school level ? or the translator doesn't have the vocabulary but I think it's the author this time. the text is full of "and so" "and then" "I then" "he then" "so I" "so he"... if only it wasn't every line, it would be ok...
  • the world building is pretty much 0. The MC is in a little town first, then he's moving to a larger city afterwards. There's 3 forest full of monsters around, a magic academy in the city and... well, that's it. We don't know much of this world and the MC isn't that interested to find out anyway.
  • the leveling system is a total BS (it's a story about a wish-fulfilling transmigration, okey, but a little logic would've been nice)
  • the characters are either totally good people, or bandits that you can kill.
  • the MC... grind your f****** skills dammit x'D why introduced the fact that MC can get any skill easily and level them up easily too (thanks to another skill) but there's is no grinding. The MC's objective is to get strong enough to survive in this world but go full assassin style (since it's the title) with a dagger. "Magic ? what's that, is it tasty ?"
  • the story seems like a full repeat every day from the start of arc 3
... more>>

"It seems it's morning"

*stretching* "yup, no problem today too"

*going down the stairs*

*iguru is calling MC*

"what are you thinking of doing today ?"

*sari came with the breakfast*

*eating in a few minutes* "it was delicious"

*going to adventurer's guild and taking a request*

*talking with the gatekeeper before running full speed to a forest*

*grinding, taking down big monsters, getting who-knows-how-many levels then back the same way*

*everyone's surprised, going to the inn, taking dinner*

*while plunging into the bed* "I'm rather tired today, it was a filled day *start a little summary then fall asleep*


  • and lastly, the translation... Am I cursed when it's a project taken by rebirth. online ? the names are inconsistent all along, that can still be okey-ish. The few 20 something first chapters, the translator choosed to add the ending japanese word for the characters' speeches. (you know, how japanese people end their sentence with a ne, na, yo,... giving a kind of information on their way of speaking, their upbringing, their personality, the politeness toward the other party...) most translators choose to use their language skill to make the reader feel it, and it works. You'll understand quickly if you decide to try this novel in english.
I ended up with way more cons than I thought x'D it wasn't totally a bad read, but I felt like I was just losing my time. some compared it to death march or wordmaster or any wish-fulfilling transmigration, but this one has been written way more poorly. These two novels at least would've be better if you're looking for that. If you wanted an harem MC then s*ave harem, road to kingdom, or any you can find with the tag on NU.

tldr : if you really don't have any other novel to read and you can turn of your brain while reading, then try, you never know, maybe you'll like it. <<less

If you don't like low tension RPG wish fulfilment novels then it best you avoid this one.

It's entirely slice of life and one of the good points is that the protagonist doesn't take any bs and does what he wants with no hesitation and you will not go "Why didn't you just do that?"

Also the title is misleading, the protagonist isn't an assassin in the sense that he iscontract killer, at least as of chapter 104. He is an assassin in the sense that he uses speed, stealth and close... more>> combat to fight <<less

It's a nice isekai story. That's about it.

The MC is likable in my opinion. Much more than other MCs in this genre. Unfortunately, the world building and plot are very poorly fleshed out.

That alone isn't its only problem. The way the MCs stats rise as he levels up is weird. It's like the author made no effort to really think up a decent leveling system. It's so simple and numbers seem to not really make a lot of sense if you start to think about them.

I gave it three stars... more>> because, like I said, it's a nice story. Good if you want to pass the time. <<less

This book is a slice of life genre, it's my favorite slice of life book, it's not slow enough to bore you to death or like any stereotypical hero constant fights and little rest. This book is right in between it shows his daily life of course but like any life, there is ups and downs. The author does a good job of creating plots that is interesting but has variations and not overwhelming, it is an at the characters speed for the most part and then he helps someone... more>> that triggers a flag. Then things get busy, then after a little the situation calms down, he gets the reputation and then back to his pace. <<less

Just your average Neet transferred to another would story. Similar to Growth Cheat but without any Citrus or s*aves so far. A good story to read if you want to read a story where the MC kicks ass without being a as*hole or a lot of angst. Just don't expect anything word breaking and enjoy the story for what it is.

PS: The first few chapters are annoyingly short more like a paragraph then a chapter really, but they get longer as the story goes on.
