60/100A fairly decent drama with some charm in its period setting that sadly only has the veneer of a mystery in its storiesContinue on AniListChuuzenji-sensei is a decent drama that uses the veneer of being structured as a mystery and having a period setting to tell some fairly charming stories in an anthology format. It is quickly made clear that the supernatural elements are just aesthetic, with all the mysteries having grounded explanations, but the summary could have been more specific to avoid any viewers expecting a more fantastical premise. While the show is also pitched as a mystery series, a closer inspection quickly reveals it only has the story structure of one given the mysteries themselves lack much intricacy, or even fairness in how they are eventually solved. This is not necessarily a dealbreaker since being along for the ride can be entertaining, even if it is disappointing that the narrative could not achieve both. The characters themselves are charming enough but also almost entirely static, with their role being mostly limited to vehicles for solving the mysteries. This places a great deal of pressure on the stories to be engaging in their own right, which is then hampered by their inconsistent quality. Things never dip to the point of becoming unwatchable or boring, but suspension of disbelief does regularly come under pressure with how the solutions to the mysteries at times rely on an incredible amount of contrivance. This is not helped by how the initial supernatural appearance of some mysteries can be paper thin. The show would likely have been better off if it accepted having a mixture of ostensibly supernatural mysteries and clearly ordinary social problems. It would have helped the show better paint a picture of the time period it is set in, which it does have inklings of but never really embraces as one of its core objectives. The only other cultural element that is touched upon is the use of the supernatural appearance of the mysteries to have Chuuzenji convey some information about the origin of these beliefs. This all still comes together to make for a moderately entertaining and quirky drama, but it does not do anything particularly interesting with its characters or setting to be noteworthy.
The framing of the series as a mystery anthology does give each episode a sense of inherent purpose that the viewer can take for granted. It follows the general structure of most mysteries with an inciting incident prompting Chuuzenji and Kanna to investigate or be drawn into the problem. However, it is painfully light on bringing any attention to the clues or the lines of reasoning used by the characters. Although Chuuzenji fills the role of Sherlock to Kanna’s Waston in this story, we do not get to hear his thoughts or rationale and are seldom made aware of information he acquires or inherently knows. To the show’s credit, it is concealed to a degree since the narrative is framed almost entirely from Kanna’s point of view, which appropriately makes us privy primarily to only her inner thoughts. As expected for the Watson character, most of her deductions or lines of reasoning do not go particularly far in solving the case, but crucially different from the norm is that she rarely has full access to the clues or pieces of information that are eventually used in the solution. Much of these mysteries are resolved with Chuuzenji coming in to essentially explain the answer, at times without even scenes of him doing much investigation. There is still the pretence of a fair mystery since the clues he uses are technically presented to the viewer at some point, but barely any emphasis is placed on them to give the viewer more information, sometimes only presenting them in a fleeting scene without any commentary or context.
The mysteries are then often resolved by using inferential leaps, which do have a logic to them but were impossible for the viewer to arrive at with any certainty through only rational deduction or inference. This is not to say the mysteries are particularly intricate or well crafted. If anything, they likely cannot be drawn out beyond the current length of being established and resolved in the same episode with how few actual moving parts there are. But more so that any viewer with even a modicum of genre savviness can anticipate the solution because of how blatantly supposedly unrelated or thematic information is presented in parallel to the mystery without any immediate rational connection. Alternatively, Chuuzenji at times comes in to essentially explain how he already solved the mystery because he simply knows more external information instead of it being based off deductions. The show does try to frame it as him having his suspicions he then confirms off-screen without informing Kanna. However, this remains generally unsatisfying because we are not privy to his thought process until the conclusion. And despite the same solution being potentially obvious to the viewer as well due to a process of elimination or storytelling necessity, there is no way for the viewer to means test that unlike the characters. Even if the show does have the subtitle of "He Just Solves All the Mysteries", it goes out of its way to conceal information as a less than graceful form of narrative sleight of hand.
Despite this lacklustre way of telling a mystery, the scenarios themselves as more of a drama are generally still passable. The constant need to thematically tie each mystery to some kind of perceived supernatural phenomenon, folktale, or urban legend does leave some stories weaker than others. Particularly those episodes that have more to do with grounded issues in post-war Japan, like in the Blue Cloak or Wicker Basket Man mysteries, often feel like they have at best only a tangential link to the initial supernatural hook, if any at all. Even when the mysteries are more directly related to cultural beliefs like the Doppelganger episode, the lengths the show goes to in order to concoct an alternative explanation that does not rely on the supernatural are often contrived or overly dramatic. These explanations are not outside the realm of possibility since similarly extreme things have happened in reality, but they cannot help but feel incredulous. Especially with these mysteries being only an episode long, lacking an extensive build up or gravitas that would emotionally justify events dramatic as being reunited with a long lost family member or learning about previously unknown relations. This still does provide the opportunity for the show to give some cultural background on the various folklore or superstition that Chuuzenji-sensei draws on, but these amount to brief overviews that are made interesting mostly by the voice acting instead of any special technique in how the exposition was written.
There is still some additional charm and depth to be found when the period elements of Chuuzenji-sensei come more into play instead of just being the backdrop for the mystery. It does a decent, if unremarkable job, of painting a quaint picture of what life was like immediately after the war. Of course, the show does not go particularly deep into the setting since it is largely ancillary to the mysteries, and would likely be unable to even if it wished with how much of the roughness of the era has been sanded off in favour of something more comfortable. The magnitude of the changes Japan was going through does sometimes become relevant with mysteries involving things like the dissolution of the Japanese nobility after the war and the entire premise of the book preparation room being to evade war time censorship. But these instances are few and far in between and are never explored much more than being used to add some period specific elements to the plot. This is understandable since painting a bleak picture of Japan after the war would hamper the generally light-hearted atmosphere and tone the show is aiming for. And to a degree, this rosy perception of the world with only slight cracks is actually some clever framing since this is all from Kanna’s perspective, a middle to upper-middle class girl who is presumably sheltered from much of the period’s hardships.
Yet this also precludes most of the interesting directions that the characters can grow it since it forces many of them to exist semi-independently from the setting. For instance, most of the adult men are presumably veterans of the war, or perhaps more interestingly had an unusual way of avoiding service, but that cannot really be explored beyond it being occasionally mentioned as a character tidbit. This is also likely a consequence of the Holmes and Watson style dynamic established for Chuuzenji and Kanna, which leaves them to be participants in the plot instead of it being used as a means to explore more of their characters. While the animation during these mysteries is nothing noteworthy, and perhaps even a little mediocre, there is enough effort placed into the cinematography and direction, particularly in visuals and atmosphere for the light horror moments, that it can keep the viewer engaged. This all ends up still being serviceable since the shows writing and voice acting are sufficient to have the characters be charming enough just through their mannerisms. There is enough to the characters to sustain one to two episodes spent simply following the fluffy and mundane interactions of the cast without a mystery really at play, but it is hard to say any of this is particularly compelling. It leaves the impression of a reasonably well realised cast with strong voices, though lacking in much apparent depth in what has been presented thus far. The show being a spinoff that somewhat reimagines the characters could explain why some of them feel a bit too exaggerated or over the top like Enokizu, but that is only tangentially relevant to judging Chuuzenji-sensei as its own story. In the end, the cast is mostly static, serving as vehicles for the mystery instead of the mysteries being used to explore their character or some mix of the two, which inherently limits the depth of the show.
Overall, Chuuzenji-sensei is a generally decent drama but nothing remarkable. There are no particularly notable elements to its construction with everything ranging from serviceable to moderately good or subpar. The parts do come together to create an entertaining enough story, perhaps emblematic of reasonably well written source material that was adapted with some due consideration, but it does not achieve much beyond being a relatively feel-good and comfortable story set in post-war Japan. As someone who is generally partial to period pieces and having seen some interesting moments shine through in how the show uses its setting, a 6 out of 10 seems fitting. It could understandably be a bit lower for someone that was more perturbed by how some of the mysteries were written, but it is still competently put together with a reasonable enough baseline quality that a five or lower would be inappropriate. Though on the other hand it is definitely untenable to say this more than a seven at its very best.

70/100An underrated mystery anime with a limited budget that teaches us the value of rationalityContinue on AniListCrossposted at MAL
There are no mysterious things in the world.
— Chuuzenji-sensei
Chuuzenji-sensei's catchphrase reminds you of Detective Conan's catchphrase: 'There is only one truth.' 'The Mononoke Lecture Logs of Chūzenji-sensei: He Just Solves All the Mysteries' is a mystery show (and sometimes a detective show). It is set in post-war Japan, and it shows how certain mysteries are not mysteries at all.
The titular character is Chuuzenji Akihiko, and he has the brain to solve each mystery. But in this anime, he is not the face of solving mysteries. It's the high school student, Kusakabe Kanna, who got involved in Chuuzenji-sensei's affairs. In order to protect Chuuzenji-sensei's secret library, Kanna had to live by the rumour that was spread that she exorcised the ghosts in the school library, earning her the reputation of being a paranormal detective.
§ Let's start with the negatives
Its animation is constrained by financial limitations, leading to limited production values. It has that one instance where blood was spilt, and it made you think of a PowerPoint animation. That instance is rare. Other than that, it is mostly acceptable. This anime doesn't really require high-quality animation. (But if it did have good animation, I would have rated this as equal to the mystery with great visuals called Shoushimin: How to Become Ordinary.)
It is episodic. As such, you don't have the urge to binge the anime. It works well for a weekly watch when it was airing, and it can work as something you can watch for 12 separate days, or if you want to be faster, 3 different seatings — watch one episode in one sitting, then watch another anime.
§ Things I am neutral about
The character design is not pretty, but it's good. One would not watch this anime to find a waifu, and in my opinion, it's not a bad thing.
Brown is this anime's dominant colour motif, and this signals an æsthetics of something vintage, old, or nostalgic. This makes sense as the anime takes place a few years after the end of World War II.
See these screenshots from Episode 12: 'The Mononoke Lecture Logs of Chūzenji-sensei' is part of Kyōgoku Natsuhiko's mystery story. In fact, I read that it's the prequel to the series, Kyōgokudō (京極堂) Series. Some would even claim that this is weak in relation to his other novels involving Chuuzenji-sensei. I don't know if it's that true, as I have to read or watch them. Regardless, I like this anime by itself, and anyone who does might consider related media — manga and novels.
A quick look at Wikipedia tells us that the first entry of the Kyōgokudō (京極堂) Series has a live action adaptation called Ubume no Natsu (姑獲鳥の夏) aka Summer of the Ubume. If this is chronologically next to 'The Mononoke Lecture Logs of Chūzenji-sensei,' it may make sense that people who liked this anime watch this next.
The second entry of Kyōgokudō (京極堂) Series is Mōryō no Hako (魍魎の匣; "Box of Spirits and Goblins"). It has both live-action and anime adaptations. The anime adaptation was made by Madhouse and directed by Nakamura Ryōsuke. There's not much from him as the main director, but he is involved in great anime as staff, great anime such as Death Note, Your Lie in April, Made in Abyss, Monster, and Hajime no Ippo.
§ What I like most
§§ The western cartoon Scooby-Doo, which was targeted to 6–12 years olds, seems to be doing the same thing as this anime, that the ghosts in question are not really ghosts. Add to that is the wacky humour.
In contrast, this anime has some level of seriousness. Despite being published as shounen in Shōnen Magazine Edge and later in Comic Days, its tone makes one think that it is actually seinen.
§§ I love Chuuzenji Akihiko the most, even if he is quite unlikable. He sees things rationally. Even if many people think that the mysteries have supernatural causes, he dismisses them as nothing mysterious, hence his catchphrase, 'There are no mysterious things in the world.'
This catchphrase echoes one of the key teachings in Lucretius as he expounds on Epicurean philosophy: that the weather and other atmospheric phenomena, which to primitive men were regarded as signs of the anger of the gods and should be feared, actually have natural causes.
For, just as children tremble and fear everything in blinding darkness, so we even in daylight sometimes dread things that are no more terrible than the imaginary dangers that cause children to quake in the dark. This terrifying darkness that enshrouds the mind must be dispelled not by the sun's rays and the dazzling darts of day, but by study of the superficial aspect and underlying principle of nature.
— Lucretius, Book II of 'On the Nature of Things' translated by Martin Ferguson Smith
I believe that Chuuzenji-sensei has done a great job akin to that of Epicurus, who had done away with superstition that leads to the fear of death, and in turn leads to having an unhappy life instead of living life to the fullest. Chuuzenji-sensei is actually battling against the tendency of the Japanese to be superstitious.
"Belief in ghosts, demons and spirits has been deep-rooted in Japanese folklore throughout history. It is entwined with mythology and superstition derived from Japanese Shinto, as well as Buddhism and Taoism brought to Japan from China and India."
— Norman A. Rubin in the article "Ghosts, Demons and Spirits in Japanese Lore"
Even a cursory perusal of articles such as Rubin's as well as 'Ghosts from the Past: The Fortune of Hyaku Monogatari in Post-Meiji Japan' and 'Traversing the Natural, Supernatural, and Paranormal: Yōkai in Postwar Japan' would leave you with the impression that such superstition is ingrained in the Japanese psyche despite all the technological advancements.
§§ Kanna and Chuuzenji-sensei have a similar dynamic to that of Houshou Reiko and her butler, Kageyama, who is the titular Dinner Table Detective. But the dynamic is better here because of the absence of the insufferable Kazamatsuri Kyouichirou.
Even though Kanna did not like being placed in the role of a paranormal detective, and she often suffers from Chuuzenji-sensei's scolding, I can see something beneficial from such an arrangement. It's akin to mentorship and enculturation to a tradition, which in this case is rationality. Just as the goddess Athena in the form of Mentor, for which the word mentor came to be, has called Odysseus's son Telemachus to man up and find the whereabouts of his father, Chuuzenji-sensei is somehow, perhaps unconscious on his part, inculcating in Kanna the values of rationality and other related virtues.
§ Conclusion
Even though it's not a pretty anime visually, this underrated anime pleases the Epicurean part of me. If not for its bland visuals, I would have rated this as equal to Shoushimin.
NOTA BENE: A grade of 7 out of 10 [or 70 out of 100 in anilist] means that I find this anime is very good and two notches above average. I enjoyed watching it.
It is a high score because it is two notches above average. It's not mid or average unlike the misconception of so many people in this site.
My enjoyment spectrum lies from 4 to 10. If I have scored an anime below 4, I actively dislike it.
