    When I first came across the manga artwork for this series, it really put me off. It seemed quite amateurish at best. Although the monster illustrations are very detailed and stunning, the artist appears to struggle with drawing human anatomy accurately...

    But one day, out of sheer boredom, I decided to give it a read. And wow, it was incredibly addictive. I simply couldn't stop reading. Interestingly, as is often the case, the art quality improves over time.

    I'm not usually into detective-type shonen manga either... in fact, I dislike the "monster of the week" style of anime and manga. But this particular series really stood out as excellent to me.

    Definitely give it a try. After reading the manga, I ended up watching the anime too, which is okay but doesn’t come close to the original manga's brilliance.

    This manga easily ranks among my favorites, mainly because it's incredibly unique. It effortlessly blends elements of pseudo-mystery, humor, near-horror, crime, action, and practically everything else, yet it never feels disjointed; instead, it all comes together perfectly. The most prominent genre is psychological, focusing on the motivations behind criminal acts rather than just how they were committed.

    The characters are perhaps the best part of this manga. From the main protagonists to even the most minor roles, everyone is well-developed. Each character feels genuinely real and human (or inhuman when appropriate), making every revelation intriguing. Some villains are portrayed so sympathetically that you might find yourself rooting for their freedom. This manga is a must-read for fans of diverse, interesting characters. There’s Neuro, the sadistic 'Evil-Good' protagonist, Yako, the terrified sidekick, and X, the childish but entertaining and slightly terrifying 'Chaotic-Evil' murderer.

    Rating the artwork numerically is challenging—it ranges from 10 to 6 at its worst. Matsui employs a beautifully surreal expressionist style, resulting in one or two complex, weirdly beautiful drawings per chapter. These artworks are distinct from typical manga styles and often used to illustrate ideas or create unsettling effects. Some pieces are so captivating that I frequently revisit them, even purchasing Japanese versions of the manga purely for these sections. However, Matsui admits that creating these detailed illustrations consumes much of his time, leading to lower quality in other parts of the art, especially in early chapters. As the series progresses, the standard of art improves, presumably due to better time management or more assistants, so it's worth sticking with.

    In conclusion, if you're tired of conventional shonen clones and seek something truly unique and unconventional, or if you appreciate bizarre artistic styles, read this manga. Even if none of these appeal to you initially, give it a chance anyway. You'll likely end up appreciating its uniqueness and be better off for having experienced it.

    Imagine a magician who appears to levitate and pull rabbits out of his hat. Now, imagine he explains the trick in full detail, killing any potential mystery. This manga is basically that. To be blunt, this manga was mediocre at best. I'm sure I'll get lots of "not helpful" votes, but let's be reasonable! It's a "psychological mystery" manga with nothing mysterious or interesting about it. Neuro solves every mystery the moment it begins. Psychological stories are supposed to keep you on the edge of your seat guessing what’s going to happen next. However, in this manga, you will never find yourself on the edge of your seat. You'll just sit back and watch Neuro expose the "trick" behind the murder.

    - - - S T O R Y - - -
    Every incident revolves around a murder. The murders are committed for petty reasons and use some sort of "trick" to cover up the criminal's tracks. The police arrive at the crime scene, being incompetent and writing it off as an accident or something. Neuro tells them he has immediately solved the mystery with 100% accuracy and explains how the murder occurred. Next, he gives the criminal an ironic (lol) punishment using his demonic powers.

    The weak cases go on for a while. Around chapters 60-90, there is a more interesting arc involving artificial intelligence. Honestly, I felt like I should just stop reading after that arc ended. It gave decent closure. However, I foolishly let my guard down and believed perhaps there would be more interesting arcs... then I got stuck reading this thing to the end for the sake of having some closure.

    After the AI arc, things took a turn for the ridiculous. The enemies became more supernatural, and things pretty much just became absurd. It was pretty much just a mediocre battle manga hiding behind its facade of being some sort of detective story. There's nothing believable about the story, so you can't feel any sense of gravity in the situations; you're basically just going along for the ride and looking at pictures of Yako having her eyes gouged, neck twisted around, or being smacked in the face. This manga has no rules or laws; it's pretty much anything goes, which just makes it completely unfit to be called a mystery manga.

    The art is not very good, but it improves as it goes along. It isn't too appealing anyway.

    Yako: Useless puppet dragged along for the ride. Her character shows some promise during the Aya Asia arc, but then she returns to being completely worthless. She basically just exists as "comic relief".

    Neuro: Invincible "detective" who instantly explains every mystery. He's basically that guy who spoils the end of a movie when you just started watching it. Very annoying personality – just not a likeable character.

    Aya Asia: Too OP. I think she just made repeated appearances because the mangaka liked drawing her. Her arc was okay, but she was made out to be too god-like. After her arc was finished, she shouldn't have appeared again. It just lowered the value of her character.

    Harukawa/HAL: This was the only interesting character, really. Despite the arc being so far-fetched, he was the only one that felt convincing. You could feel his attitude loud and clear, he didn't have any stupid "comic relief" involved, he had deep emotions, and he had a true motive.

    X: Wildcard with no personality.

    Sicks: Hitler wannabe.

    Everyone else: Pretty much pointless and irrelevant.

    The constant S&M stuff was pretty stupid. I swear, 50% of this manga is just S&M. It completely degrades Yako's credibility as a character and also just makes Neuro a really bratty and annoying character whom you can't take seriously. Also, it fails to be funny unless your sense of humor is so lowly that you'd be amused to see one person get whacked over and over for no reason.

    The characters are pretty much all just one-dimensional. It's hard to feel any attachment to any of them. In the final battle, I honestly didn't care if Neuro would die or not. I mean, really, who gives a shit? He didn't really contribute anything to the story. Barely anyone did besides Harukawa/HAL.

    If you're expecting a mystery manga, this isn't one. Just don't bother reading this; it has very few interesting points.

    Main conclusion: not brilliant, but certainly a good read.

    Story;
    A girl named Yako, whose father was murdered, encounters a demon (spelled consistently as "deamon") called Neuro, who solves the 'riddle' of this unsolved case. Neuro feeds on riddles and desires to consume them from the human world. He uses Yako to navigate through human society, making her a famous detective. Her role in their detective agency mainly involves smiling friendly and maintaining close contacts with the police.

    The first 60 chapters consist of short stories. There is indeed a major villain (X), but he remains in the background. The short stories all revolve around murder cases where the murderer tries to hide their guilt through a 'riddle'. Some riddles were far-fetched, but overall, they were nicely executed.

    After these initial 60 chapters of short stories, another significant villain emerges: a computer virus that turns people into criminals. This plotline occupies about 30 more chapters. Then we return to short stories for another 30 chapters. X's role grows, becoming more prominent. These short stories have an underlying theme concerning the cat-and-mouse game between X and Neuro, leading up to chapter 120.

    It turns out X is merely the beginning of the troubles ahead. A super villain responsible for X looms, forming the grand plot of the story. Thus, the next 80 chapters focus on the conflict between this super villain and his minions against Neuro and the police squad.

    The shifts between small stories and the main storyline are, in my humble opinion, too drastic. Reading this manga in one go feels disjointed. However, the way characters from different stories fit into the bigger picture is well done.

    Art;
    At first glance, you might think Matsui-sensei's art isn't noteworthy. You'd be mistaken. Upon closer inspection, you'll find pleasant surprises. It's evident that Matsui-sensei appreciates art, showcasing this in various ways. For instance, through a story involving an artist. The sculpture drawn by Matsui-sensei for this story was outstanding.

    Matsui-sensei's drawings clearly draw inspiration from several artists. Neuro's demonic form, for example, reminded me of creatures in Hieronymus Bosch's paintings. Other demonic elements had aspects reminiscent of Dalí. Several images, like those showing Neuro sitting on the ceiling, were obviously inspired by Escher's works. Matsui-sensei also shows a clear interest in surrealistic cubism à la Picasso.

    Character;
    The characters evolve throughout the story. You can see genuine changes, some for the worse, adding realism. I appreciate how Matsui-sensei doesn't shy away from letting characters die. However, the portrayal of several murderers or the supervillain veers far from realism.

    Enjoyment:
    It was an enjoyable story to read. I liked it, though I wouldn't say I loved it. The comic relief was nice. Neuro's sadistic traits were amusing, and Yako's eating habits were hilarious. Translator notes mentioned many jokes were untranslatable due to their reliance on kanji readings. It's a shame, as it would have enhanced the story further.

    I'm not quite sure what to make of this manga. Initially, I thought it would be similar to Ghost Sweeper Mikami, where the main character derives pleasure from tormenting others. At times, it's amusing and almost devilishly comical. Whether it's due to the translation or the actual writing, the story becomes incredibly intricate as it progresses. Be warned: you will get confused, misled, and likely exclaim, "What the hell?" while reading this.

    The manga begins simply with a demon entering the human world and coercing a human into assisting him. Let's discuss the main characters for a moment. Neuro is a demon who has ventured into the human realm in search of riddles, which serve as his primary source of nourishment. Most of the time, he acts like a playful child, albeit one with a penchant for satanic and torturous games. Born and raised in an underworld of suffering, where concepts of death and horror hold no sway, Neuro's behavior reflects this upbringing. Place such a character in our world, and they wouldn't understand why it's wrong to toy with someone's mind or show them horrific images. That's why I view him more as a child playing with his food than a genuine demon, given that the riddles he consumes are created by humans. His quest for the ultimate riddle stems from a desire to quench his hunger.

    There's another aspect of Neuro worth mentioning. Despite his childish nature and lack of understanding of humanity, he exhibits a peculiar insight that borders on psychological acumen. At one point in the story, he remarks on how humans continually surprise him by surpassing his expectations. This got me thinking about the underlying psychology within the manga and its parallels to real life. For instance, there's a singer whose beautiful voice emerges only when she feels unloved, leading her to murder those she cares about to regain her vocal prowess. As an outsider observing humanity, Neuro seems to grasp more about us than he lets on. When delving into these psychological nuances, he appears more human than usual.

    Yako, on the other hand, isn't as well-developed as Neuro. She comes across as an ordinary girl who somehow withstands Neuro's bizarre antics. How can any human endure having their head twisted 360 degrees or their jugular repeatedly smashed? It makes me wonder if Yako herself might be some form of monster, especially considering her eating habits. Although she claims to dislike riddles initially, she gradually develops an interest, showing signs of understanding by the second book. Her admiration for Neuro is peculiar, almost bordering on affection—though just slightly. It's odd to see shoujo elements in a shonen manga, blending aspects typically found in girls' comics into boys' comics.

    The artwork combines occult themes with shonen aesthetics, clearly targeting a male audience. However, Neuro's character design appeals to female readers too—he's oddly cute in his own way. Despite his monstrous true form, his playful demeanor, particularly around Yako, adds a whimsical touch. Their dynamic resembles a cat playing with a mouse, devoid of malice. Neuro never seriously harms Yako, and their relationship hints at potential friendship. The artwork itself is filled with surreal, horror-laden imagery, featuring fish-eye lens effects and strange details related to the riddles or weapons. Characters often transform from simple to complex as they approach solving the 'riddle.'

    This manga is undeniably strange and complicated, leaving much of the ending unclear even after multiple reads. It remains a good read, but careful attention is necessary to fully grasp its intricacies. If anyone could explain the ending to me, I'd greatly appreciate it, as it continues to baffle me.

    INTRODUCTION

    After completing the fantastic anime adaptation, I found myself yearning for more mysteries, clever humor, and of course, more Neuro. Initially, I hesitated due to the artwork. In fact, I spent the first few chapters complaining about it. But before I knew it, I got completely absorbed and ended up reading most of this manga in a marathon.

    STORY 10/10

    The manga primarily consists of short cases. Although the criminal is usually made obvious to the reader, the process of deduction and explanation remains exciting. This series focuses on the "How" and "Why" aspects of the case rather than the "Who." Each story stands out in its own way, with each criminal having unique reasoning tied to psychological conditions. As the main plot progresses, readers encounter stronger adversaries that Neuro must face, eventually leading to a main group of antagonists.

    One of my favorite aspects of Majin Tantei Nougami Neuro is the humor. The overall story is dark and psychologically disturbing, but the author manages to lighten the mood with some equally dark comic relief. It may sound contradictory, but Matsui-sensei makes the reader laugh at things that aren't funny at all. Despite not being a fan of violence or cruelty, I find it amusing when Neuro tortures his prey and destroys their psyche. Likely because Neuro himself is a contradictory character, which brings me to my next favorite aspect.

    CHARACTERS 10/10

    This has to be one of the best, if not the best, parts of this manga. Let's start with the title character. Neuro is certainly one of the most unique characters I've encountered over many years of enjoying anime and manga. What makes him interesting is his ability to capture the reader's heart with his negative qualities. He is selfish, sadistic, manipulative, hypocritical, and plain psychotic. He takes pleasure in inflicting mental and physical torture, including on his partner Yako, and never misses a chance to belittle humans. He could easily be the main villain. However, Matsui-sensei successfully makes this character lovable. What is Neuro's charm? How does such a seemingly repulsive individual become so attractive? Is it his eccentric appearance, childish demeanor, or the mystery surrounding his existence? There may not be an answer. Neuro is a paradox, a hateful character that cannot be hated.

    Our co-main character is Yako, a pretense detective and Neuro's favorite "toy." She may appear ordinary and weak, but she has a strong personality and a lot of courage. She isn't afraid to speak her mind when confronting criminals and is deeply concerned about their motives. Her main purpose is concealing Neuro's true identity, but she also aids in solving cases due to her knowledge of human psyche, unlike Neuro who only cares about solving the puzzle. She is very open with Neuro too, even though her life is in danger every time she talks back at him. As the story progresses, Yako matures and starts living up to her title of a detective.

    There are numerous other characters, and I won't go into detail about all of them. I don't think there is a single boring personality in this manga; both positive and negative characters are intriguing in their own way. Majin Tantei Nougami Neuro avoids overused stereotypes common in this genre. There is no invincible hero who doesn't get hurt and can easily escape any situation. Legit detectives are not as useless as they usually are in stories involving amateurs. The antagonists are not your typical gang bent on world domination; there is no clear good versus evil scenario. Characters grow and change, making the story very exciting and unpredictable.

    My only concern is that nothing is known about Neuro himself. Everyone seems to have a backstory and motive, but Neuro just exists. He is from Hell and he eats mysteries, that's it. Whether or not the author planned it this way, for the protagonist to be the biggest "enigma" himself, is unknown. Even though he is a mystery, his character seems complete, and it didn't strike me until the end. Only after finishing the manga did I realize I don't really know anything about him. Maybe Matsui-sensei plans to reveal more in a second series. Or perhaps it's just another paradox.

    ART 8/10

    As mentioned earlier, I was initially repelled by the artwork. The proportions don't seem realistic, and there is inconsistency throughout the designs. The focus is on the foreground, while background characters are drawn with less detail, sometimes lacking facial features. It appears the author focused more on developing the story and characters than making it visually appealing.

    Even though the actual panels are nothing extraordinary, the full-page chapter inserts are definitely worth looking at. Here, the artist shows his talent by drawing characters with much detail and in difficult perspectives. Among them are fascinating illustrations adding to the disturbing side of the manga; for example, an image of Yako sitting in someone's eye and looking up from under a contact lens. Also, looking closely at those inserts, we see how they depict character quirks; for example, an image of Neuro wearing a kimono and black boots inside a Japanese house, showing his indifference and disrespect toward humans and their customs.

    Majin Tantei Nougami Neuro is among my Top 5 favorite manga series, and Neuro is among my Top 5 all-time favorite characters. I highly recommend this to everyone—it will surely keep you entertained. There is a "to be continued" notion after the cliffhanger ending, and I am definitely looking forward to a second manga series.

    This manga stands out as something truly unique. It's definitely not for everyone, given its peculiar humor and disjointed narrative. Nevertheless, if you persist, you'll discover its brilliance.

    Story-wise, it's undeniably strange. The manga spans across multiple genres—from comedy to horror and even psychological thriller—yet manages each transition seamlessly, making the shift from funny and bizarre to serious and unsettling almost imperceptible. Yuusei Matsui has done a remarkable job. Additionally, it delves into various mental states through its villains and characters, handling these themes adeptly. The story unfolds in four primary arcs:

    1) The initial segment (up to chapter 60) features distinct, unconnected cases, serving primarily as an introduction to the characters and some foundational development. Here, the main villain is introduced but remains largely inactive.

    2) This arc introduces a new villain with ambitions of world domination. Remarkably, it never becomes tedious; the motives and continuity are flawless, culminating in a highly satisfying conclusion that might even evoke emotion.

    3) The central antagonist starts executing his plans, forcing the protagonists to intervene. It's incredibly engaging, though I can't elaborate further without risking spoilers.

    4) In the final arc, the ultimate villain emerges, causing chaos on an unprecedented scale. Certain scenarios induce anxiety or disgust like never before. The ending felt somewhat generic to me, yet oddly acceptable, possibly due to the numerous open-ended possibilities it left behind.

    The characters are all superbly crafted, each receiving ample development. It's one of those rare stories where you can't help but sympathize with every character, regardless of their malevolence. Even seemingly insignificant supporting characters become endearing. As the plot advances, some characters meet their demise, which is heart-wrenching. I shed tears over one character's fate, and others' severe injuries pained me deeply. Their realism compels you to care about them profoundly.

    Assessing the artwork was challenging. Initially, it appears rather crude, but improves significantly as the series progresses. Certain segments are illustrated exceptionally well, capturing meanings, absurdity, and comparisons perfectly. The artistry here is simply outstanding, though difficult to articulate; you'd need to experience it firsthand to understand.

    In summary, despite feeling somewhat monotonous at the start, I thoroughly enjoyed it. My recommendation: persevere. Push through the initial discomfort, as it will undoubtedly reward your patience later on.

    I find it significantly superior to the anime. Majin Tantei Nougami Neuro is a psychological, mystery manga that delves deeper into detective work. What I appreciated most about it is how it portrays Neuro with a blend of frightening yet quirky and humorous traits. If you enjoyed the anime and are eager for more intricate details in the storyline, or if you have a penchant for detective games and puzzle-solving (and also love FOOD), then I highly recommend this manga for you.
