Kawahara is a writing machine. I was afraid picking it up that it would feel like a regurgitation of his other stories or that it would feel like his third series that was an after thought. After reading it, I must say that I was wrong. I felt like there were no similarities at all to Sword Art Online. The only slight similarity there is to a previously written Kawahara work is the nature of the Eye's abilities manifesting in an individual being similar to the subconscious generation of the avatar that one uses in Accel World, beyond that its a real world non MMO game not even set in the far off future. I greatly enjoyed it. Actually in comparison to Accel World this book feels much faster paced and a bit more gripping as I was able to get through 100 pages in just two days of reading, while Accel World typically takes me much longer at times. Kawahara is really focused in this one with little to no tangents present.

The magic battling, Isolator, story focuses a lot on the trauma that the two characters of choice have in this volume. One is the antagonist who one could easily feel the pain and stress was felt while the other is the lead who was caught up in a bad place at a wrong time. I could see how one would just want to be isolated and forget about their past and everything. Though Im glad that we dont stay in that state for the whole volume and series with the lead character showing some growth mentally and emotionally by the time the last page is read.


Only flaw is that it seemed Kawahara is unsure if it will get a second volume or become a series. I hope it sold well enough so that the publisher will allow it to continue. Though I guess it wouldnt come out as fast as Accel World and Sword Art Online volumes since he wants to maintain his six books a year schedule.

This entire book was depressing. That's all I have to say about this. I will not be continuing this series at all. I have absolutely nothing positive to say about this book at all. The Main Character has got to be the most emo person created ever and all the mistakes that he makes despite being an extremely smart person make no sense at all. I'm not even going to go into tear down mode on this book. It was just depressing as hell. I've got to go and read something funny now just to level out.

So far, I've only read two light novels that I absolutely couldn't stand- this one and Maid Machinegun. While the other was bad because of ordinary ineptitude, however, The Isolator actively infuriated me. First of all, the fact that the villain here is a cannibal that only eats fan service fodder girls and stops to admire them before meal time is intensely off-putting. Monstrousness aside, I'm not sure the literary world needed any anime-style cannibal fetishism, but if you, as a reader, want that, here you go.

As much as it repulsed me, however, at least the eating people stuff in this book was original. I still didn't like it that well, but the first half of this novel is a well-written, smart character study of a protagonist and a villain and their divergent attempts to overcome the sorts of horrific pasts that can only be found in YA novels. All of this setup, however, is wasted on a never-ending drag of a battle that takes up an incredibly long stretch of the novel. Character development is wasted on a ridiculous super-powered set piece, filled with bizarre gore and at least one personal revelation so stupid that it cheapens the first part of the book.

The worst part of The Isolator, though, is how much it ends up falling back on cliches. The main character has a superpower beyond the scope of what's been seen before? Really? Tell me more! Does that brash, snarky girl that he just met secretly have a heart of cold and a sweet spot for him? Who knows? Let's find out! Wow, do you think that the aliens have some sort of long-standing vendetta on their home planet that they're using humans to settle? I don't know, but I'd sure be shocked if future volumes revealed that to be the case!

And, seriously- if you're writing a light novel, and you have to pick a code name for a character, you're seriously going to sit there, nod, and go, "Yes. I pick Accelerator. Never been done before, good job, me!"?

On a technical level, the prose itself in The Isolator is well done- it's clear, keeps the story going, and, to an impressive extent, equalizes the importance of bloody action and internal monologues. The illustrations are really nice, too, though there's one I kept staring at while thinking, "What exactly am I looking at here?" The prose and illustrations, however, are in the service of a story that is repellent and stupid. Needless to say, I have no intention of keeping up with this series.

This is easily the best Reki Kawahara novel to make it into English. Hero Minoru is neither a sad-sack like Haruyuki (Accel World, Vol. 1: Kuroyukihime's Return) nor is he a Gary Stu like Kirito (Sword Art Online: Aincrad), and his plight is understandable. There are a variety of female characters, and the plot is totally game-free. Even if you've grown sick of his other properties, this is worth reading.

(Longer review will eventually appear on The Anime News Network.)

Reki can write believable worlds so well. The mechanics of his sci-fi are well-thought that it felt like you are living in his created world. That said, he can’t write characters as well as he can write world building 😭.

I noticed that with SAO and in this book that his male protagonist often are loners, emo-kids, usually awkward boys. Makes me think that most of his books are wish-fulfillment.

I love this book, it makes me want to read the next volume. Though Minoru is a tad bit emo compared to Kirito (the SAO MMC), I like his writing in here more.

honestly, loved the concept of the story but then i stared reading and it just wasn’t good. felt like it was just rambling on boring stuff that didn’t matter.

loved the different type of main character, (even tho he was annoying at time), but nonetheless different. but, yet again, the writing style wasn’t it for me.

- Hardcover with color illustrations. Illustrations throughout the book were smaller than usually in a light novel and were surrounded by a thick black border (why???).

- Pov was 3rd person and alternated between Minoru and the Biter.

Minoru Utsugi is a troubled young man. When he was younger he survived something horrible, something no one should have to go through, and now years later he is still trying to cope with what happened. Just not in the healthiest ways.

He wants to forget everything, but even more than that he wants to be forgotten.

I’ve never quite met a character like Minoru before. He’s mentally weak but physically strong, and yet he stands by his convictions. Throughout the novel he confronts his way of life (he has this way of over analyzing his every action and deeming it ultimately selfish) and he changes, he grows, and still by the end of the novel he doesn’t change at all.

It’s interesting, and I look forward to the next book to see how this plays out.

As for the Biter, he starts out as man with a biting trauma but by the end of the book I just felt sad for him (sad for all the characters really). In some ways The Isolator reminds me of the A Certain Magical Index series, just without the optimistically happy ending. In some ways The Isolator feels more realistic.

The concept for this series is a simple one. Three months ago most probably alien eyes enter the atmosphere and attach themselves (like parasites) to unsuspecting humans giving them the ability to use a unique to them power.

The Biter gains the ability to bite through anything, and a voice telling him to eat and eat and eat people. The Isolator (aka Minoru) gains the ability to create an invisible shield around just himself, and so far no voice that talks to him.

Based on this book it sounds like these eyes only go after people who were horribly traumatized when younger (even the Biter, by the end learning all I did about what happened to him I didn’t feel satisfaction or happy when he lost, just regret that things turned out as they did) and it looks like Reki Kawahara is not afraid to show this.

It’s funny, when I first started reading The Isolator I was bored. It was a typical story about a teen with a power who just wanted to be left alone and stumbles on an incident that won’t let him be left alone. There’s even an “organization.” But then, near the end of his fight with the Biter, as I read the last or so scene from the Biter’s pov I felt a click happened in my mind.

This book touched something in me, and by the end I was left with this feeling of quietness. It’s hard to describe, but even though I felt sad, it wasn’t painful, I didn’t even feel like crying, it was just life, and sometimes life is sad. Even now as I think about this book that feeling of quietness comes to me, it was worth it to keep reading because any book that can leave me feeling like this is a book I want to read again.

Kawahara did such a great job describing the character’s mental pain. Some of the best parts for me were Fragment 01 and The Biter’s past and true feelings about said past. When he goes into what his favorite shark is and why I just felt for him.

Lastly there is no focus on romance here. There may be in future books (come on this is the guy who writes Sword Art Online and Accel World which are both harems I believe) but for now this thankfully had none.

And I just have to mention this, but according the Kawahara’s author note he writes six books a year... what kind of insane writing schedule are you on Kawahara!?

Final Thoughts: Any book that leaves me feeling like this one did is a book I really really like. The beginning ( Fragment 01 ) was great and I learned some interesting facts (like how to knock someone out) and probably more information on sharks and the different types than I needed to know. But the characters really shined, and once I got past the part where Minoru realizes he has to change and The Biter becomes a person to me I really got into the story and I want to keep reading this series.

I want to know how these characters will continue to grow, and if Minoru’s wish is granted just what a world would be like if

"The Isolator" is a latest young-adult/light-novel from one of the contemporary superstars of the genre, Reki Kawahara, most famous for the "Sword Art Online" series of books.

The Isolator is a traditional light-novel. For those who read Sword Art Online though, this book is not alike; whereas SAO is considered a light-novel solely for its demographic and country-of-origin, it was really a complete story, a science-fiction novel through and through. But "The Isolator" is not that; this is the first book in a series that barely scratches the surface of the science-fiction/fantasy future of 2019 and space-alien superpowers that comprise its innards, and ends on a deep cliffhanger that promises much much more so long as you keep buying the books. This is what Light-Novels are: alike much of Japanese pop-culture, its a design meant to reach a mass audience and convince them to commit to a lengthy, expensive interest in a project that extends over multiple entries (and, very often, multiple mediums as well).

The Isolator: Volume 1 is okay. That's about all I have to really say about it, because there's not much that happens besides establishing what the next entries in the series will be based on. Characters are introduced at a very slight level; all but the main-character remain deeply shrouded in mystery, cloaked in the various tropes typical of Japanese pop-media that are meant to be shed at later, more opportune times in following entries. The action-conflict is established at an elementary level: three months before the novel begins gemstones from space fell quietly onto Earth and entered into certain persons. If it's a black gem, you're a good guy: if it's a red gemstone, you're a badguy. This the depth of context that this first volume bestows on this, so obviously much more is hidden than is revealed in this book.

This is a 200 page novel, and alike SAO most of these pages are action passages. This is still a rather weird thing to read because action in literature very rarely "does" anything. Action-scenes are just a lot of stuff happening that, while directing of characters' evolutions to come, also stalls the text from getting to that; most skilled or learned western authors keep action-scenes to a minimum, utilizing them only when absolutely necessary to the story, but this is not the case for many Japanese authors, and this is especially the case with the Light-Novel genre. I've written about this same thing in other reviews of Japanese Light-Novels, so I'll repeat simply: be prepared to zone out repeatedly if you're not familiar with (excessive) action-passages.

There's the problem that massive amounts of action just isn't that exciting in literature; in videogames and anime lengthy bouts of action are paramount to the consumers engagement, but in literature it's really rather boring, and honestly meaningless. This is something that the target audience of young/early teenage males might respond to, but for adults this degree of activity is definitely going to deflect from the story, as the medium just doesn't depend on such a thing.

No less, I enjoyed The Isolator, although it is a very limited text that offers little else than a framework for later entries in the series which will, hopefully, be much more insightful and evocative. I very much like the radically entertainment-oriented sensibility of Japanese light-novels, and while I am not persuaded that a hundred+ pages of action passages are good writing I do find much enjoyment in reading about the initial usage of superpowers, human transformations, and other comicbook-like elements. Such grandiose activity hasn't really been done by western authors; and certainly among the available translated Japanese light-novelists so far, Reki Kawahara does action-writing the best.

THE ISOLATOR, POWERED BY THE SOLITUDE. SOON TO BE A MAJOR MOTION PICTURE DIRECT TO SCI-FI CHANNEL BY ASYLUM STUDIOS.

Honestly it's quite generic but Reki has gotten to be a very good writer and it kept me highly engaged. I'll give this a weak 4/5, it's always hard to tell how good something will be from the first book, I got good hopes though.

Minoru lost his entire family the night someone invaded his home. Now he wants nothing more than to get through life without impacting others at all. No more memories, good or bad, for him or anyone else of him. But his strong desire to have a minimal existence has one major problem: when the alien orbs descended three months ago, one of them chose him. Now he has the power to completely isolate himself, but others received more malevolent abilities . . .

This was a lot deeper than I was expecting. It's an excellent picture of both Minoru, who reacted to extreme tragedy by turning in on himself, and also Takaesu, whose twisted childhood set him down the path of becoming a serial killer.

I liked that Minoru really struggles with connecting to other people in the wake of losing everyone who was important to him all at once. Even though this book hints that some of the people he's met would consider him a friend, he's not ready for friendship. He's defining his relationship with them by how quickly he can get rid of them, and how he can try to smooth over anything they might find memorable about him so he can fade into the background once again. Other characters don't get him at all, but he's got that quiet desperation that drives him, and he stands up for his own convictions.

This takes an interesting twist when he finds himself somewhat responsible for putting others in danger. He doesn't wish on anyone else the same kind of tragedy he experienced, so he steps up despite wanting to keep a low profile. It's also fun how he ends up using his perfect isolation to fight. He's not a skilled fighter, and his abilities are entirely defensive, but he can do quite a lot more than I expected with them. (And the book never did answer if he will eventually run out of air if he keeps the shield up too long.)

It was also interesting how deeply the powers tied in with who the characters are. Minoru getting isolation powers is easy to see, but I loved that the villain's biting powers made just as much sense. In both cases, the orbs latched on to an obsession in their host and amplified it past all reason. Given that, I'm looking forward to seeing more backstory on his new teammates, to see why their powers developed the way they did.

Overall this was a very nice surprise. The sci-fi/supernatural elements are flashy and fun, but also grounded in well-realized characters. I am looking forward to see where the rest of this series goes. Recommended.

This novel series turns 13 years old this 2022 (First published on 2009). First time I have read it. Reki Kawahara is best known for Sword Art Online (SAO) VRMMORPG (Virtual Reality Massively Multi-player Online Role Playing Game) the "death game" and Accel World (also about a VRMMORPG). This Isolator series is about extra terrrestrial/SuperNatural Powers (third eye) that adapts to the "strengths/traumas" of the people that received them.
Kawahara is a sadist, or has really strong tendencies to torture, kill, abduct, damage his main characters and supporting characters. This author uses most of his characters as punching bags/ meatshields / Kidnapped victims. Has no regrets or moral compass about it.
This first volume starts out confusing, not really to the point. So aliens give super powers to some people, depending on the color of the cores these people turn evil (feed on the evil of the hosts) or are able to be used for "good", if the characters that get the "good cores" aren't complete wimps-non-commital-afraid-of-their-own-shadow-characters that are neither role models, nor are they able to defeat the evil antagonists well. Minoru Utsugi (main character here) and little and fat Haruyuki (in Accel World series).
Main character has no special abilities, no skills before aliens gift him a "third eye". No extraordinary intelligence, martial arts abilities or supernatural abilities.
Main character is probably non-committal, weak and fearful of everything and everybody because he still feels guilty/responsible for the violent death of his family. Main character, probably wanted to die instead of them, or die with them and not be left behind. Main character does not want any new friends, new relationships or new acquaintances because he feels that if he has new relationships, he is just setting himself up for new violent deaths or new life/death problems.
Because main character has never received proper therapy, he desperately seeks isolation and the loss of his memories, so that he cannot worry anymore about people that are going to "die" or have terrible problems around him.

3½ stars. I rounded up because I like Kawahara and found the book to be interesting, it a bit flawed. Minoru wasn't to be left alone. Alas, the world(s) are not going to grant him that wish. He finds himself embroiled in the middle of things beyond his ken.

Many others have written about the plot so I don't feel the need to summarize too much. I found Minoru's character to be interesting with a dash of frustrating. The other folks who are part of the fight do not alleviate that frustration much, especially once they realize Minoru is a Jet. He is just left to his own devices rather than explain, help him cope or understand (hence some star removal).

Oh the whole it is a decent book, the first in a series that isn't the same as Accel World or Sword Art Online. So if you like Kawahara at all, probably at least worth checking out.

Another fantastic book by Reki Kawahara that has a different feel to his other series, although still planted in sci-fi genre.
As it's the first book in the series, most of the book was character introduction and world building but it doesn't feel over the top or forced. Most things at this stage are still shrouded in mystery, making me wanting to get my hands on the next one asap.
An interesting change to Kawahara's previous novels is that this book was written in thrid person with multiple perspectives. I felt that this change allowed a broader view of the plot, but at the loss of not feeling as close or relatable to the main character (thought it could be argued that this is the way the main character wanted it).
Overall a great start to a new series that I'm keen to continue with.

I can't stand the main character. The only thing he does is whine. I don't want to be remembered. Memories are hard to bear and a bad thing. Bla Bla Bla... I hoped for a good Light Novel and don't get me wrong it is not that bad, but the main character is really annoying.

(4.5) I ended this volume falling back in love with Reki Kawahara's writing. The Isolator is a solid first volume in an ongoing series that has me invested and eager to see where things go, a few quirks aside. I can't wait to pick up the next few volumes!

Low expectations after experiencing how disappointing the first few SAO volumes were. Surprisingly fun to read. Minoru is also a more compelling MC than Kirito, though that's not a high bar.

Minoru Utsugi is alone... or, at least, he wants to be. Ever since a tragic incident in his childhood, Minoru has wanted nothing more or less than absolute solitude- and he may get that wish.

When mysterious orbs known as "Third Eyes" come down from outer space, they go inside human bodies and give them powers based on their wishes and memories. But these powers aren't free- black "Jet Eyes" grant these amazing powers- but the red "Ruby Eyes" don't just grant their hosts powers- they also give them homicidal urges.
Tomomi Minotsugi is an ordinary high school girl- when she encounters Minoru for the second time, she's determined to befriend him- but can someone as isolated as Minoru really have friends?
The Ruby Eye host known as "The Biter" has the teeth of a shark, and uses them to bite people, and his latest target is an unassuming high school girl. But he's stopped by the impossible- other Third Eye hosts- who he didn't even know existed.
Yumiko Azu is a Jet Eye host, codenamed "The Accelerator". She works for an organization of Jet Eye Hosts working to take down the Ruby Eyes. On what should be a normal assignment of rescuing a girl from a Ruby Eye Host, she encounters another Jet Eye host. She would love to recruit him, but he wants nothing to do with her- or anyone at all. Can she convince this pig-headed idiot to join her side?
Norie Yoshimizu is Minoru's thirty-one-year-old adopted sister. She took him in after he lost everything, and he knows he'll never be able to repay her- but when Norie gets put in danger because of his problems, he knows he has to save her- no matter the cost.
Into this crazy mess Minoru is thrown- what will he do- and can he ever really reach the absolute solitude he is searching for?

I think The Isolator is a hard one to recommend because it skews towards an older crowd in instances (ultra violence in certain scenes) while also remaining very clearly a piece of YA lit (you see this in some of the characterization and problems the characters deal with).

The premise is interesting. These alien beings in stone / eye form (think Berserk's Behilit) come down from above and take some control over a human host body, giving them enhancements to their abilities. It seems like a bit of a PG / PG13 take on the manga / anime Parasyte. There is a twist involving the powers and aliens that I won't spoil that makes it a bit more unique. At the end of the day, I was somewhat intrigued by the set up.

Your characters aren't necessarily archetypes you haven't seen before, but they are still executed fairly well. There's an undercurrent of human hangups that the two perspective characters in this volume have, and accepting / overcoming the past seems to be a key theme going forward.

Overall, it just didn't catch my interest that much. I think they introduced a few too many important characters to start the novel series, some of whom seem more damsel in distress / hangers on at this point than actual characters. I hope we get to learn about each of them more in later volumes, though I'm not left on the edge of my seat after the end of this volume to learn what happens next.

Interesting, but I feel like the light novels are just letting me down. This would probably get another star if the writing didn't feel so choppy, which I think is probably an issue of an overly faithful translation.
Also, I kind of wish that there wasn't set up such a clear division between good people with powers, and bad people with powers, but that's more a minor thing at the beginning of a series that might deal with it later anyway.

Una historia interesante y entretenida, aunque es un tanto cliché ver ese tipo de chico que es antisocial y que posee de repente un poder extraño, la trama entretiene y mas porque nuestro protagonista busca la "Soledad Absoluta". En cuanto a nuestro primer villano, estuvo genial en especial porque nos relata su historia y como es que llego a ser asi; otro punto a favor es que esta conocemos los diversos puntos de vista algo que en las Light Novel es muy interesante.

A pretty good story. It had some intriguing ideas and it held my attention really well. I'm not used to having a deeper understanding of the enemies perspective while reading which definitely made this story unique. I am really interested in finding out how this story unfolds in the next couple of volumes.

I tried several times to read this book, but I never made it very far before I was distracted by something else I wanted to read more. Maybe when I get through more of my backlog, I'll try again but, more likely, this title will move on to a friend who would enjoy it more.

3.5. This book was fun and I really liked it. But still, I'd be really hesitant to recommend it to anyone as the writing/translation can be quite a struggle and you need to be quite a forgiving reader. If you are though, this is totally bonkers!!!
