Tohno Hifumi was summoned to another world to be a Hero for a kingdom. Unknown to the summoners, he’s a person who had restrained his killer instincts with martial arts.

Afraid of letting more people get killed by Hifumi, the Princess–who is the only one to managed to keep her sanity act rationally–let him go free.

Edgy chuunibyou: The Novel.

I'll keep this short. The MC is a mad dog who lashes out at everything for the tiniest reasons. He is an evil scumbag, and that would be perfectly fine if the author didn't try to give him have the moral high ground too. Commit to having a villain protagonist, FFS, don't try to say "everything he does is actually okay because blah blah blah". That is the biggest flaw of this story and limits so much of what it could be.

Usually I do not have problem whether MC is evil or good as long as it fits well in story but not here. The story is about a strong guy who after being summoned in different world wants to use his martial arts and kill people. I would understand somewhat if MC killed people or did some other evil stuff to achieve his goals, but his goal itself is just to kill and murder, nothing more. MC is no different from psychopaths and maniac murderers.

The protagonist is a master martial artist and a psychopath, he kills anyone that opposes him and his goal is making the world enter into something like the Sengoku period with everyone fighting each other.

In later chapters he gets his own territory (that ends up like a fortress thanks to slave dwarves), controls the kingdom as he likes and is running around spreading chaos with his army. The side characters are fun, notable ones are a princess, a mage and an airhead, the princess developed into quite the character, the... more>> mage was brainwashed into a yandere and the airhead is the best general ever. No serious love interest so far, mage is the only one trying to compete, princess despises him from the royal capital(a little brainwashed though), and airhead is airhead.

Also, I'm not sure what happened, but around chapter 30? the writing style REALLY improved, it might've been the author getting some sort of editor or the main translator being changed, anyways, before it was as if a middle schooler was writing it and I was about to drop it. So, if you're thinking the writing is bad, cope with it for a while to be pleasantly surprised. <<less

Kinda lame. Brutal killer mc who repressed his nature in Japan so he wouldn't go to jail. Ends up in a fantasy world and just kills. At first, it seemed he had reason. I killed because you kidnapped and were using me. Later you find out he was a psychopath who likes to kill. How can I trick people into attacking me so I can kill them.

The fantasy world is built on the premis that humans lack the desire to fight each other. Humans mainly fight other races, there... more>> is a minuscule amount of wars between humans, so the mc comes in and brings our worlds knowledge of warfare to this seemingly peaceful world. He becomes untouchable with this knowledge and just kills friends or foe. It doesn't matter as long as he gets to kill. Which means there's no real story needed, no plot, no good character development, or any character smarter than the mc. It just has something for the mc to kill and the over powered method the mc kills it. <<less

I don't really get how everyone in the other world knows nothing about warfare and fighting. There are multiple kingdoms that obviously was founded and hold territories from one another but somehow are incompetent at warfare and constantly get their asses kicked by a guy who's not a soldier, has no experience commanding armies, and has no fighting experience outside a dojo environment. Goodbye suspension of disbelief. The MC is a charmless psychopath, everyone except him holds the idiot ball, chapters were named after songs most of which do suck...... more>> Seriously though, its not like he's using a very different paradigm in fighting compared to people of medieval period so I don't get why he's too successful (aside from his dumb as rocks enemies) <<less

It was never very good to begin with but as it progressed the story just got more and more boring when it should have been the other way round.

The main problem with the story was that most of it was written from the perspective of irrelevant side characters who had almost nothing to do with the story. As the story goes on the MC goes from having 50% of the story to less than 5%, to the extent where the story isn't even about him anymore, just about the... more>> thoughts and adventures of random soldiers and politicians and their encounters and schemes which have little to do with the MC.

By chapter 50 the amount of boring irrelevant politics mounted up so much that I just couldn't bear it anymore. Endless amounts of irrelevant politicians scheming this and that and then they get killed by the MC at the end for going against him and his plan of essentially destroying the world so that he can have more fun killing people.

>How can I trick people into attacking me so I can kill them.

This exactly sums up the entirety of the MC's motivations. He doesn't care about anyone just wants to kill people for the thrill of killing. To make that more fun he spares his enemies and makes them stronger so he can kill stronger opponents.
MC constantly says "I'm not invincible, I can die at any time" but in reality it's the exact opposite. In one scene he goes against 100 trained soldiers (who are wearing armor) with just a chain sickle and a spear or whatever Japanese weapon it was and kills them with just martial arts. He walks up to random people and just kills them if they displease him in any way (e.g by not submitting to his ridiculous demands). He's like one of those villains from a terrible shounen manga. <<less

Not certain what I was expecting. It began as the synopsis said - killer in modern times that moves to another world. He gets slaves. Corrupts them. Then things go to shit.
His "fights" can be condensed into 2 paragraphs for every one. It goes something like
1. Encounter
2. They try to stab him
3. He miraculously counters and kills everyone with ease.

Eventually degrades into him being a politician with a penchant for murder. You know, that villain in every other story that the author tries to make into... more>> an antagonist but is really just a B-rated Hollywood bad guy, if more hands on. <<less

The first dozen chapters are pretty good, it is refreshing to not read a beta mc story. However lately the chapters have been devolving into an edgy and incomprehensible mess.

Every chapter seems to be focused on the main character massacring villager A/B. While the few side characters exist just to have toddler level intelligence just so the author can make his main character seem to be a genius in comparison. If you want to read a novel that has a well developed world, side characters, plot, or slice of... more>> life then don't read this.

tl;dr If you want to read how the main character kills random person with one slice of his sword every chapter 50 times then this is for you <<less

If this were DnD, then the MC (Hifumi) would be aligned at "Chaotic Evil" - if you like baseless killing/destruction then this is the novel for you.

A little bit more depth would have me say that this is extremely lazy writing. The author changes the MC's personality to be more and more brutal. At chapter 72 the MC is a gigantic douche for no reason other then he shall be entertained..

This doesn't factor into the low rating, but there is also the usual BS about how great katanas and japanese... more>> martial arts are.. <<less

Warning, if you do not like slow character development, then do not read this. Honestly this series is pretty darn good. There have been alot of complaints about some stuff and i would like to point out the flaws in some of the accusations.

1- Regarding Formations during is a fact that the 'single file line' into battle was used up to the 1800s. in fact i do believe that the British was still implementing this during WW1. This story is set during the 'mid-evil' (5th-15th century) Europe.....I can... more>> say more about this topic, but i will stop here and just say that the argument about war during this time is pretty accurate.
2- Regarding MC wanting to fight stronger people...if you are a martial artist, then you would know that you train to be the best. Everyone wants to find out if they are the best at what they do. Most martial arts where created during periods of war and turmoil. To defend, to protect, or to kill. Although the origin of martial arts may be found gruesome and disgusting to some people...remember that you dont live in an era in which your house may belong to another country the next day or that bandits are breaking into your house raping your wife, daughter, mother, or just killing everyone cause you just gave them a look they didnt like.
3-MC skill VS knights...i believe this story is set some time in the early mid-evil age (5th-15th century). Following this logic, the knights only have a good 500 years of history of combat to go by to train and honed their skills. This is limited to their region or kingdom they belong to. (Assuming their country is that old, cause America isnt even 300 years old) Now you have an MC that comes from the modern world (20th century). As stated in the first chapter he has mastered a sht ton of martial arts and knows the history of martial arts. MC has a 1500 year of experience in martial arts passed on from one generation to the next. Honed and perfected as each generation goes by. Now when you compare the MC and his skills to Knights of a kingdom which has yet to develop any techniques, its pretty obvious as to why the MC is so 'OP'.
4-Politics....just gonna go ahead and say if you dont like it. dont read this. It is obvious as fuck that if there are multiple countries then their will be politics. Especial so in a world filled with monarchies. If you dont know what monarchy put it blunt a country ruled by a king or queen......
5-MC's goal of war everywhere.....What can i say he already explained himself. War is the mother of innovations. Regardless of your opinion this is a fact. Tactics, weapons, political reforms, medicine, transportation, jobs, ways to preserve food, and so much more are created and innovated. If you do not believe me...*face palm* go back to high school and this time pay attention to history class. while your at it, hop on google and search innovations during WWII.)
6-Character Development....for the MC is a very slow character development. But the story isnt about him as far as this subject goes. Its about everyone he meets. Let me tell you its a sht tone of development. From the moment he meets the princess, from the moment he saves the two slaves, from the moment he gets his own territory, to the moment he spares an enemy knight cause that knight knew he wouldn't be able to kill MC.

Over all this series is one hell of a series its one of my favorites. For those who do not like a slow development or do not like the idea of causing war on purpose do not read this series. <<less

Personally, I think being needlessly antagonistic is just as bad as being needlessly nice.

What to make of this novel? I can’t say it’s a good piece of writing. But I can derive my enjoyment from some mindless killing without caring about the story and characters. It is, after all, something fresh from all the niceties that infect novels. Just proceed while keeping in mind that MC is just a psychopath with some screw loose and you’ll be good. I was abit bumped out because the author tried to justify... more>> the MC action and attempted making him out to be a cold-hearted intellectual while in fact he’s just a rabid dog. <<less

Needless murder. That's the whole point of this series, nothing else, everybody will be killed later by the MC just for petty reason, then forgotten soon.


Even the ending is noncommittal, that the author resuming it on a thousand years timeskip gaiden series with the same MC just to start another whole killing festival, with new characters to kill. Hillariously they releasing the seal for the supposed "hero" so they can be killed again, that world never learns.

The MC is both heartless and ruthless, unlike most wuxia/xianxia MC's where they are mostly ruthless. I disliked the MC at first because he killed someone after receiving a gift from him. Later, it seems the author changed that aspect of the MC, and only killed those that got in his way, which is better then returning kindness with enmity. The MC is a powerful sword user, but he is using knowledge of his modern day world, to start building his own kingdom. He trains people... more>> in fighting, educates as far as giving exams to some, and has weapons and railways built. I would highly recommend this, unless you are a self-righteous douche. <<less

This novel is one of my favorites! There are quite a few novels out there with anitheros, but to me the majority of those characters just don't feel as genuine as Hifumi dose. The novel itself spends a decent amount of time on creating a background for the story to take place in, which isn't necessarily a bad thing if its done right, and I believe this novel dose it. If you enjoy antihero protagonists that give this novel a whirl, but try to get up to... more>> chapter 40 before you drop it. <<less

The start was impressive but later on it got boring real fast

The MC in this light novel is a self driven murder maniac and entertains the idea of taking another persons life. When I started reading this I thought to myself 'wow what a really interesting mc' however after a few chapters later 'this guy is really bland'. MC is really one dimensional, after his slaughtering so many people you throughout the story you can actually feel numb from killings and tell yourself 'why is this so boring?'. As the... more>> MC straight up GARY STU character where he could do no wrong and his approach to making a world of violence makes no sense too (entirely the author faults).

Another Light Novel with summoned Hero. oh wait, not hero, but a villain. yes, you heard me right, it is a summoned antihero-protagonist MC just as mention in the tag. so, if you want to read a novel about triumphant over-powered hero from parallel world, just give up, it's not a novel for you.

This novel has unique story, as the MC has only goal to create situation convenient for him, which mean a situation where he can spill as many as blood as he can, yes, he is bloodthirsty MC.... more>> not for the sake of revenge or anything, just for his pleasure. interesting, right? <<less

While I am all for the ruthless MC's, it seems that this novel uses it as an excuse for poor plot execution, and lack of writing ability. The entire first volume is fairly rushed, I don't feel attached to any of the characters, and over all terrible. Clearly, even though the author tries to have the MC have some logic incorporated into his brain, it is very illogical and incomprehensible. He contradicts himself too often and has a very flawed personality.

I don't know where to start, the plot unfolds in a complete beautiful manner, characters are magnificent (MC?, Origa?), not to mention that each chapter is TITLED WITH A SONG NAME! Also what I like about this author is how he almost never repeats what he has written before, and that the characters seem to follow a realistic train of thoughts of a human, even if that human is a psycho, I mean I swear at one moment I thought of something and the character just said it afterwards:
... more>>

“Hasn’t that girl somehow gradually turned more scary from before?” (Sabnak)

“Shh! Be quiet!” (Midas)


Now going back to the MC, how Original and refreshing is that? Although I like to read other novel of the same genre/tags (transferred to another world/ to game / reincarnated ), and liked how everyone differs in their plots, this one completely satisfies me while reading it.

Last note will be how there is minimum fillers, and minimum fillers, I didn't skip even one line of each chapters, as my first review to write on this site, This is my top recommendation to anyone one who like this genre/tags like I do. <<less

Mediocre at best.

Plot: the initial setting made this novel stands out from the rest of JP cliche. As the story progress, our MC ultimate objective becomes killing everyone who stand in his way. This is a good point since his objective was clearly defined.

Structure: Is a MESS. It seems that the author did not plan before hand. The story feels flat without any climax or significant events. The more I read, the more I felt my enthusiasm leaving. In addition, I felt the story just progressed too fast

Characters: Another mediocre.... more>> Most characters here lack depth. Either because the author was focusing on the massacre by MC or most characters were swallowed by the fast paced story . Hifumi was too engrossed in killing, Origa suddenly developed feelings for Hifumi and Kasha gradually got less and less screen time. in short, most characters are not memorable at all.

Writing: Okayish. Readable just like the majority of JP novels and suitable for your 3 minutes bed time story. The 3rd person omni-narrator point of view didn’t help much against lackluster action scenes and flat story. Still better than 1st point of view employed by many other harem novels.

In addition, the war scenes were epic-fail. Emotions and feelings of war wasn’t conveyed properly and lacking diversities. Most came from the view of an OP character which is our MC and it was boring.

In conclusion, once the novelty of this novel wears off, eventually you will be sick of MC killing spree. <<less

Master samurai OP MC is transferred to another world and his only goal is to create capable warriors so that he can fight them. How does he do this? Plunge the world into chaos and war so that people must become more skilled to survive.

The MC is capable. He has no interest in morals, pleasures of the flesh, money, power, or anything other than a good battle. People call him a psychopath just because he kills without a second thought, but he doesn't have any erratic thinking, he... more>> stays consistent throughout the entire story, never swaying from his goal. Really one of the best MC's I've come across.

There is also an extremely yandere slave girl that follows him around. <<less

MC is a straight homicidal maniac who's only character motivation is killing (strong) people - but really he'll kill anyone. Fine, we can roll with that right? But then the story is just a mess of problems.

1. The setting is laughable to a point of unreality. The people he is killing are supposedly humans but they're just SO DUMB. And it's funny because the author is working off this typical WN template of a world (with adventurers guilds and mustache twirling evil nobles and whatnot) but then expects us to... more>> swallow that no one has ever thought-up a tactic more complex than 'mass the guys up in a line and charge'. And the inconsistency is glaring, like how can you have a society where people can and do wage wars but every military commander in the history of ever was moron? You can't have 'evil-conniving nobles who are constantly scheming below the surface' and also 'idiots whose only ability is to tell a guy with a spear to go poke someone'. The setting is filled with all these seemingly mutually exclusive elements because the author started with this generic fantasy world template and then just adjusted everyone to moron-level so the MC could seem really smart - without giving any consideration to how unreal is makes the setting feel. Why is there an adventure's guild but not a merchants guild? So MC can fire off a quip about it duh.

2. MC is really poorly characterized because he never faces any sort of adversity. All of his interactions with other characters are 'Help me or die' only what sort of help and for how long changes. Because he's mega awesome and strong nothing can challenge him so he just wanders around killing whatever. It's a story more or less completely without tension because only side characters can die and you don't really care about them because - remember the premise now - all MC does is want to kill things. No adversity = no possibility for growth, all we have to go on about MCs character is his internal monologue which is always just 'I sure like killing things'. In the story I have read thus far he has never shown any degree of giving a shit about any of the other characters except to lecture them a bit before he kills them sometimes. And when he gets flustered talking to a girl once or twice. Because you have to write for your audience I guess?

3. So the setting sucks, the MC is boring with no possibility of growth or change, really the only thing left to carry it is the fight scenes and the side characters. I skim the fights so no comment there (he always wins remember) and the side characters seem to mostly exist to show off how cool MC is, or to reappear a bunch until you get slightly invested in them so they can be killed.

This came out a bit harsher than I intended but whatever it's an ok way to kill an afternoon if you can find it in you to overlook the various gaping plot-holes and just enjoy the premise of 'there's a really strong guy who wants to kill strong people in a world of people made of tofu(including their brains)'. <<less
