In a certain world, there was someone who excelled in magic combat, people called him 『Sage』. Seeking the strongest combat art, he devoted himself to research every magic and combat arts in existence. And the conclusion he arrived at was very cruel, 『My body is not fit for magic combat』. Yet he didn’t give up. He sealed his own soul with a magic art, and was reborn in a far-off future. And the magic theory in the completely changed world he saw there was of unbelievably low level.

I tend to like this type of novel, but its done so freaking poorly. The beginning is fine enough but the lack of common sense is destroying the whole crest type power system in the story.

(spoilers below)
... more>>

It was a new system so I was excited, but the MC beat the seasoned father in combat at age 6 and acted like oh is that incredible? He's supposed to be this freaking sage but he doesn't even have the basic deduction/reasoning skills.

Furthermore, when MC is trying to reinvent/teach the old/right way to do magic, he acts the freaking same. Introducing chantless, enchanting normal weapons into legendary grade weapons. He acts like thats nothing special. He did foreshadow how someone screws over the people so that their magic system sucks like hell, but he doesn't do anything about it and simply tries to change the traditions of an entire world by teaching things at school.

Another point is how illogical the plot is. He makes a freaking legendary sword in 10 secs and that never comes up again (besides teaching other students or other students bring it up). That kinda thing should have more consequences, (greedy people, gov control, untold fame) BUT NOTHING COMES OUT OF IT. Also, he beats the knight captain of all freaking things and has chantless magic but its too dangerous to go into a dungeon unless he gets 4 other students with him.


(no more spoilers)
This just might be my opinion, but MC just has the stupidest problems for his power/skill level. The plot is also really slow considering how much he has to do to face those problem. Actually saying its slow is wrong, but pointless. I like how overpowered he is, but when he has to do so much pointless stuff in a inefficient way (teaching) with no real consequences, it just makes it so painful to read. The plot is literally a straight line where the author alternates between making him overpowered but then how to make him normal with the whole world going at his naive pace. <<less

I dont really like this kind of stories

The story is only about a man who is reincarnate to fulfill his will and found next generation is on decline

The author is really bad at making stories about social relationship
i dont know if author wanna make something story which is light and fresh to read but I dont really like how author tells the stories just like monologues

It's fine. I like seeing overpowered characters, but this one is a little too cringey for me. I also like romance, and although it's obvious at least 2 of the characters like the MC, there's no real development. I didn't think their conversations were that bad, like some other people, but they just constantly praise him. I've probably seen the words "There's just no common sense when it comes to Mathis" and "Only Mathis can do that" like 300x within these 144 chapters. It's pretty annoying.

Hopefully the future arcs get... more>> better, but at this point it's not that interesting. I binged it in ~8 hours because I had nothing else to do, but if you're expecting something to seriously be a fan of, this won't be enough. Just read it if you like OP characters and have finished everything else. <<less

Simple but not bad: basically unplug your brain to avoid common sense alarms, and you'll be fine.

The main character (and the whole cast) is a little too stupid for my tastes, but it's still bearable. Also the plot is a little too quick to solve.

It is fun to read, but come on a 1100 year old person lacking in common sense hello author? Sure he reincarnated into the future but, a 1100 year old person (soul) being all that naive and not minding the surrounding?

Edit: So yeah. It is a good read. Fast paced, no dilly dallying. I would give this novel 3 star. So why am I complaining early about character? Because he is the character the story revolves around!

Edit: Lost counts how many times I changed my review. I have grown more... more>> fond of this novel and Sousetsuka is doing good translation. <<less

This is *bad*. It's fun if you can overlook a lot of eyerollingly silly things, but it's pretty awful. It's perfect cotton candy reading: delicious for a certain type of craving, but there's better dessert out there, and it may make you sick if you get to much at once.

Things I like:

I'm a sucker for OP characters that make the villain cry.

... more>> I adore little history bungles that get brought to light (oh, the God of War? Yeah, he was a pacifist, you know?) <-that kind of thing.

It's fun when common sense gets pounds into the dirt.

Things that made this not great, even as brain candy:

There are no other characters than the MC. There are author cutouts to play the part of sounding boards, yes men, cheerleaders, or convenient target practice, but there's nothing developed enough to be considered a character.

There's no tension. Anywhere. There is no problem that can't be solved with his past knowledge, powered through with his new crest, or bowled over with his sheer awesomeness. It's not that I dislike OP, rather he just pops out a solution for everything, even if it hasn't ever come up before. He is the deus ex machina.

And finally, there are times when things just make no sense. Like telling the human firm dragon to use a spear instead of a sword, because somehow that would be easier to understand for a beast that uses claws and fangs to fight. And it works. I don't know why.

All of this is packaged in the usual light novel writing style that makes the epic sound lackluster. Meh all around. <<less

Good translation, bad novel.

The story is bland, theres a feeling of no real development. They make everyone else incredibly weak from the start which gives you a feeling of zero threat. Obviously I don't expect the MC to die, but have you ever heard of set backs? Idk maybe I've been reading to many Chinese novels were theres actually people much stronger than the MC, and he gets his ass kicked. He then gets stronger and learns from his past losses. This novel? Start at he very top, and just... more>> invent a higher peak. I feel the last of development early on is just due the laziness of the author being unable to have everything fully though out before he began writing. <<less

It's not a bad novel... but like many other reviews and complaint, you would think the author know better. That someone who lived a full life and gets reincarnated would do some research or at least learn the common sense in this new era he is living in. Instead you get an OP character who think what he does in his past life is normal while everyone else is like "WTF!?!.. but doesn't try to explain to him how the way he do things is way out of the ball... more>> park like in magi grandson. Like seriously, they even mention its not like he took over the body but his old memories merge with the new one so its like an awakening but he acts like nothing's change in how many years it has been or has pass before he got reincarnated. Also he goes around throwing his OP skills like there's no consequence... even Death March isn't this stupid and its like the king of easy-going, OP over 9000 tier right of the start MC, just my opinion on this.

Sorry for rant, this kind of stupid thing just irks the sh*t out of me, which is why personally I won't be reading this. However, as far as review goes it's still a good read and Sousetsuka does a decide job of translating, as some are into this kind of genre. For everyone else just take any reasoning.. matter of fact take your brain out for a walk then read this because it will annoyed you when you try to put common sense into this novel. <<less

Okay let keep this short.

We know the OP common sense breaking MC genre. Yeah, this is one.

However, you don't have to invent the wheel every time. Like, the Avenger movie, everything in the story is predictable. You know the good guy will win. You know the MC will be OP but what truly make or break it is how it was tell.

Like a clown who hold no shame in being the clown. The MC in this story is a down to earth guy from the Era on the myth level... more>> of might, so ofcourse the today era seemed like a gathering of inept idiot compare to him. Moreover, unlike a certain people (I am looking at you Mile), he hold no attempt in hiding his power and that kind of benefit everyone with any amount of intelligence and save the reader from slow plot. And he have a good reason to do that too. The main humor here is how the MC see the world common sense and he is totally correct.

Like Everyone is a Returnees, the strong point of this novel is that it tell it joke well. Old joke can work better is it is told correctly and this guy go this in spade. One problem thought, people should at least question MC a little bit more.


well considering the fact that they have demon invasion and the dude who would question him should be directly suspect. This cushion the fault somewhat but not enough honestly

Personally, I don't dislike novels where MCs are OP or expanding his harem at every corner, or the fact that most of the actions that the MC takes defies common sense. However, I've seen quite a few other novels with similar context and this is just more or less copy-pasted content for quite a few other novels.

... more>>

The MC, despite being several hundreds of years old, can't even handle a girl and still stutters when talking to one. Like, hello? You managed to slay a dragon famed to be the world's strongest, but you can't handle a conversation with a girl? Where did your experience of living for hundreds of years go?


Anyway, moving on, a part of the novel which is a total turn-off for me is the fact that the author keeps recycling the "lack of common sense" card. Just about every other action that the MC makes, the people around him will more or less go "oh I forgot, this guy doesn't have common sense". Seriously, mentioning it once or twice is fine but the joke gets old after awhile and quickly gets lame. "Magi's Grandson" is also another novel in which the author keeps pulling the "lack of common sense" card at every corner of the novel and it's so pitiful that the author can't think of something else to create humor <<less

Basically, a slightly better version of "In a Different World with a Smartphone".

MC is not reincarnated from Japan but from the past of the same magical world and has a lot of knowledge lost to the current population. There is actually a plot but sadly no real tension because the MC grows to fast and resolves problems rather easily.

It's a lighthearted story and OK to pass some time but personally I've got pretty sick of the repeated trope, where the MC does something amazing what he considers normal, everyone around... more>> him is astonished because it defies their common sense and the MC although growing up in this era is confused by their reaction. It's repeated every second chapter or so... <<less

This novel isnt half bad. The thing that I like is that the main character is realistic. He thinks things through and acts accordingly. Some may complain that the main character is cut and dry, but all his actions so far were based on reason so he is actually pretty good. But the problem is everything else. Author made main character too overpowered too quickly. The same problem as Death March, there is apsolutely no suspence because MC will fix it right away and I get that is given since... more>> he was the strongest mage, but if that is so the author should focus more on side characters and main characters personal problems (like his lack of social interaction) rather then fights like in Death March. <<less

Haah, author simply pulls sh*t out of his ass as needed.

No real background to be based on, no issues. I mean ok it's slice of life, isekai op MC, but even in those there are certain issues characters face, in death march avoiding god spotlight, managing harem, having fun, in a way they're challenges MC faces.

Hell even in smartphone there's later kingdom management and discovery.

In here it seems that utter degradation of human knowledge and idiocy is the only issue MC faces. And it's not like anything develops, sh*t pops... more>> up, MC magically deals with it because he's so awesome and then author forces another issue cause why not.

I like this type of stories and I'm reading it but honestly despite having decent start but I'm starting to feel like im reading someones masturbation log. <<less

I don't know why I read so much of this. I guess it's a bit like junk food where you mindlessly read a bit and click next. Since the chapters are so short you end up 50 chapters in after an hour or so. Yes, the chapters are short but when it comes down to it a lot of the chapters could even be further compressed considering how it neglects details, character building, and plot building. Every once in a while a nice mystery tidbit is thrown in, like how... more>> the previous world fell but then it's immediately glossed over for overly elaborate descriptions of magic systems. The magic systems are the only things that get details. Not their effects, just the system behind it. Every arc (if you can even call them arcs) always have the same beat as well. OP MC does something impossible, people are shocked and make a comment about how their common sense is broken, he kills some demons, and then something happens and the next arc starts, ad infinitum.

TL:DR The world is flat, the characters are flat, the MC solves all problems without issue without much help if any and there's no plot. Just skip this one. I'm not even sure why Sousetsuka picked this one up. <<less

Similar to Death March, easygoing story. But compared to Death March, this WN :

1. The protag much denser than the one in Death March

2. The characters lack personalities. This is the most minus. In Death March, the characters brimming with strong personalities. So even it's the same easygoing story, it always refreshing and cute.

3. The story pace feels quite fast but somehow progressed so slow. It's already 160th chapter yet it only progressed 3 arcs.

It's a good story. Since the MC is already OP in the past, even with the handicap first crest, it's not surprising that he will be more OP in his new crest in his new life.

But since the world's magic level became low and his OP, and there's so many characters that rely on him, it became boring. Also it became annoying when the MC said lines like "I could do better in my previous life but this is the limit of what can I do now" repeatedly, even during... more>> battle, when the enemy will do a strong attack he always have a hidden trump card prepared, yeah REPEATEDLY.

Well, I feel like even when I'm currently in chapter 50's I feel like I am reading an early chapters, so maybe we can expect changes in the future releases. HOPEFULLY <<less

it is a fake shonen light novel...

no true sense of danger when the world has fall apart (believe it or not, it is a post-apocalyptic world)

inteligent MC but only think with his muscles at non crucial moments... (why the world end like this? meh idc)

... more>> it is shonen because MC is op, intelligent and solve things with punches.

it is fake because there is no sense of danger, no blood, no deaths

now tags, they are not that bad so far...

he is not dense... I see no romance in the ln yet, he knows there are tons of problems around the world, he just ignore it because... it is not related to his dream? I am not sure why he ignore it..., and well he was a freaking genius in his time so I believe that his common sense back then was not the standard of common sense of the time either...

genre on the other side... I see no harem, no romance (perhaps there was something for 1-2 chapters but no more after 171 chapters so far)

i see no school life... sure he lived in a school (it is not mentioned though) but other than the implicit him as a teacher instead of a student, there is nothing of value (and pretty much 150 chapters are related to school lol)

the novel is ok for amusing, I expect it will be cut down though... why? well MC said this "i want to fight those universe beast (or something) but I need 300 years and a solid team to be ready" after 171 chapters only a bit more than 7 months has passed, it is slow paced as a snail <<less

Romance: ERROR 404: Not Found.

Harem: All members are as bland as Maki Nishikino - Just pretty but boring as hell.


... more>> It's a repetitive cycle of MC doing something which is new to the new world.

Defeating enemies like a walk in a park.

Enemies are a bunch of retards.

Saving Grace:

It's quite normal that he's powerful since he's the most powerful wizard during his time in the past before being reincarnated into the future which regressed drastically instead of progressing. So it's quite fresh unlike most fantasy novels which the MC is OP for no good reason.

It explains things in detail.

The chapters are short.

Bad Side:
This ain't an "isekai" novel you got tricked.

Bland and Repetitive.

It's just a novel of training his future party prospects, teaching the dunces of the current world about magic and dungeon busting. <<less

This novel is the epitome of average, the plot, the writing and even the translation is average, it isn't bad by any means, but it also doesn't reach the height of the better ones out there like wuxiaworld. The chapters are extremely short with the whole story feeling rushed and lacking in explanation, about the world, the concept of magic and experience, the latter of which is the way to grow in mana in this novel.

All of this also results in there being no way to really categorize people according... more>> to strength, all we know is that the MC for some reason is OP after hunting birds for 6 years, since it's said in the prologue that he's going to be reincarnated with only his memories, none of his former strength.

The fact that the MC is op isn't that bad, especially when there's talk in the prologue about enemies out there being stronger than even his former self.

The premise of the story in itself isn't bad and the MC is likeable, even though he's clueless he isn't whining all the time like you see in a lot of other novels and on top of that I actually found myself grinning or laughing at times, normally doesn't happen for most novels on here, even the ones people say are funny are regularly stuff I find lame and think only 12 year olds would laugh at, so if you're like me, you might find this one enjoyable. <<less

The intro is easy to misunderstand, in the past, 4 crests have the same value in the world the one he had is by no mean weak, it's just the only one not suit for combat.

The story, no, one (or a few) of the main point of the story is the same as "world teacher"

While the number of word is average, somehow the actual story in each chapter is (extremely) short. It's best to combine 2 chapter as 1. MC... in early state (until chap 20 and might even further)... more>> he's almost void of common sense.

As far as the story goes, it's more like MC reincarnate to the "past" rather than the future, it doesn't "look" like magic has gone down but rather like a stone age. But unfortunate... it is, and hell, he's like a god in his past life <<less
