Reviews for The Mononoke Lecture Logs of Chuzenji-sensei: He Just Solves All the Mysteries

I’m putting this under “mixed feelings” because how much you enjoy this anime depends heavily on what you expect from it. If you check the “related” section, you’ll see Mouryou no Hako, a 2008 anime by Madhouse. It’s an adaptation of the second novel in the Hyakki Yakō series a dark, atmospheric supernatural mystery series written by Natsuhiko Kyōgoku. That anime (which I liked its 7.5-8 ) was gloomy, complex, and definitely not for everyone. It can be confusing and the ending may not satisfy everyone, but it had a strong supernatural detective vibe which I appreciate. So why am I bringing that up? Because thisanime Chūzenji-sensei Mononoke Kōgiroku is a prequel to the Hyakki Yakō series. It shows a younger Akihiko Chūzenji (aka Kyōgokudō), working as a school teacher before he becomes a bookseller/detective. Other male characters like Kiba, Enokizu, and Tatsumi appear too — they’re all present in the original novels and Mouryou no Hako. The only new addition here is Kanna, who exists only in this series.

Before getting into the anime itself, it’s worth noting that this manga/anime wasn’t written by Kyōgoku. It’s written and illustrated by Aki Shimizu, who previously drew the manga adaptation of Mouryou no Hako. As far as I know, Kyōgoku did approve this project, so it’s considered canon even if it doesn’t feel like it.

Disclaimer: I’ve only watched the anime and read the manga for Mouryou no Hako I haven’t read the original novels.

Because it wasn’t what I expected at all. It’s light. It tries to be funny(unsuccessfully). It’s unserious. The mysteries are boring. And worst of all? The characters feel completely one-dimensional and barely resemble their original counterparts. I can describe each character in one sentence — which is a terrible sign for a mystery show. In contrast, the original characters were layered, ambiguous, and genuinely interesting.

Kiba: A musclehead police officer who’s kind of dumb.

Tatsumi: Introverted and anti-social (this one’s a complete 180° if he didn’t have the same name, I wouldn’t even know who he’s supposed to be).

Chūzenji: Just a grumpy teacher. (Again: who tf is this?)

Enokizu: The only one who kind of resembles his original self a bit weird, still a private detective.

They’ve all been flattened into anime clichés. They’re no longer intriguing or complicated they’re just dull and lifeless. In Mouryou no Hako, I was worried about them, second-guessing their motives. They felt real. Here? 1969 version of scooby doo has better written characters and mysteries and Kanna? She’s just there so the mystery has someone to funnel it toward Chūzenji. That’s it. No deeper purpose.

The anime is set in 1948, in a post-war school where weird, “supernatural” events keep happening. Kanna, a second-year student, teams up with Chūzenji, who helps her solve these cases but only under the condition that she pretends she solved them and never mentions his name. That’s the entire premise.

It could have worked but the mysteries are insultingly easy. If you’ve read any mystery or watched any detective story, you’ll guess what’s going on in the first 10 minutes and you’ll be right. Even if you’re not into mystery, you’ll still figure it out. That’s how basic it is. The mysteries aren’t entertaining. They don’t make you think. There’s no suspense or tension. And most of them wrap up in one episode (1.5 max). Out of the entire 12-episode run, I’d say only 2 episodes had remotely decent mysteries.

Even if I ignore the original novels, I’d still call this an okay-at-best anime. For viewers who have no idea what Mouryou no Hako is, it’ll come across as just another forgettable mystery anime. And for fans like me who liked the original this’ll feel like a frustrating attempt to be something it’s not. The only group I can see really liking this is people who want a slice-of-life mystery with zero tension or complexity something you can just put on and vibe with it

I’m giving it a 4/10, and I do admit that my review is heavily biased because of ı like the original source and characters . Maybe if I hadn’t known the source, I’d have liked it a little more. Try it if you’re curious but if the first 2–3 episodes don’t grab you, don’t bother continuing. It never changes.

Bonus nitpick: I don’t like the character designs either. They’re too bright and bubbly for me I like my mystery anime with darker tones (which is apparently illegal in 2025).

And again its in mixed feeling because this review is biased and I advise people to try it.

This has to be this season's best fun slice-of-life, light-hearted anime. The 'historical', 'mystery' tag might lead people to believe that there is some big conspiracy, scary ghost mysteries to solve but no, it's an anime based around school kids that are afraid of rumours and the main character, a charming bold girl along with a stoic sensei solve it together. It's nothing but light-hearted fun and a huge bonus is the mystery solving and mononoke angle of it. Every episode is an introduction to a seemingly supernatural occurrence, and introduction to Mononoke lore. Chuuzenji sensei and Kanna-chan's solve it together and unravel stories about thepeople involved. Most of the time the conclusions are pretty wholesome.

The two main character's interactions are also really cute, like a father and daughter relationship. I feel like I'm Kanna-chan's classmate, walking peacefully on the streets of Tokyo, as I get introduced to her friends, laughing at their childish fears.

The animation is satisfactory, not amazing but enough for a slice of life anime. This anime touched my occult and mystery loving heart somehow and if those are your area of interest, I'm sure you'll enjoy it too. Also, the children are adorable.

Set in yee olde Tokyo of 1948 comes this detective story. Kanna, our main is a student and plays Watson to the Sherlock Holmes inspired Sensei Chuuzenji. The episode starts with a hint of the supernatural or urban legend then Sensei walks on and logics it all down to earth, the end. And there is a white haired dude in there that is clearly supernatural but we don't talk about that! While the artwork is... fine, just fine. The animation is stiff as a board. It actually brings the whole show down. Sensei's job is to mug at the camera. No really, that's it. He's a pureSherlock Holmes dupe and nothing else to where it's actually boring.

The premise of the show had potential but between the stiff characters, the obvious "mysteries" and the poor animation it just too rigid and not entertaining enough to keep you interested in what's going on.

Normally I'd give this a meh 5 and mixed bag since there is nothing REALLY wrong with it, however there are better detective shows out this season that by comparison this one just doesn't hold up.

The Mononoke Lecture Logs of Chuzenji-sensei: He Just Solves All the Mysteries — Yup, you're reading it right: the show's plot is right in the naming itself. In literature, they say that “the simple things are also the most extraordinary things, and only the wise can see them,” as summed up by The Alchemist author Paulo Coelho. And in fact, history is ever so more poignant in our world than ever before, exploring the past to make do with what the present brings to form the future ahead of us. It's this notion of thinking that is even more prevalent in the supernatural mystery side ofthings, of detective stories and the like. And what better place than in Japan would you get resurging tales of Japanese folklore, which always seem to resonate in the minds of its people? This is where you'll find acclaimed author Aki Shimizu writing her own interpretation of the folklore, one of which is in the form of this show — Chuuzenji-sensei Mononoke Kougiroku: Sensei ga Nazo wo Hodoite Shimau kara. a.k.a The Mononoke Lecture Logs of Chuzenji-sensei: He Just Solves All the Mysteries, based off of legendary writer Natsuhiko Kyogoku's Rozen Kreuz Series novels (of which Madhouse's adaptation of Fall 2008's Mouryou no Hako a.k.a Box of Goblins, is one of them).

In fact, I would say that this show actually parallels more towards the famed mystery author's piece of Ubume no Natsu a.k.a The Summer of the Ubume, based off of the Kyogokudo series. In a rather chill-pill-like way, Aki Shimizu opted to change things quite a fair bit by featuring its MC, atheist onmyoji Akihiko "Kyogokudo" Chuuzenji, in a mid-20th-century Tokyo rendition of a supernatural mystery that's based in the culture of 1948, as a teacher in a school setting where mysteries do occur, and he's the only one who, because of his knowledge of the supernatural mysteries, can make sense of all of the "nonsense" that's happening around the school. The POV also changes to the ordinary student of 2nd year, Kanna Kusakabe, who, along with her classmates, regularly encounters the supernatural mysteries that are happening around them for no apparent reason. So then, within the sleight hand of a hidden room within the school building, lies Chuuzenji-sensei, lying in wait, or the elusive young girl, ready to hear her annoyances and be the one who "He Just Solves All the Mysteries".

If there is one thing about Aki Shimizu herself, it is that she KNOWS how to draw beautiful works of art, as she was the main contributor for a fair few games, the most significant of which is for 2002's Gensou Suikoden III: Unmei no Keishousha a.k.a Suikoden III: The Successor of Fate, as well as her own interpretation of the game's story itself. However, when it comes to her writing, as is evident from her own original story of 2003's Qwan, it's not the best, and honestly, the sum of her artwork alone can be passed off as being worth more than the things she writes. And Chuuzenji literally suffers from bad writing so much that it's no wonder it wasn't labelled as a detective-esque show, alright. I mean, to have supernatural mysteries that range in a similar vein to other detective/mystery stories (the most prominent of which is Kamonohashi Ron no Kindan Suiri a.k.a Ron Kamonohashi's Forbidden Deductions), but just written so simply and not at all complex, it shows that the story element was to take a backseat for the other aspects of the anime to shine.

And if there is one area the show definitely has its guns on, it's the characters. For one, Akihiko Chuuzenji himself is quite the stern, no-nonsense languages teacher that keeps to his books and doesn't want to get into all sorts of trouble, let alone the girl of Kanna Kusakabe that always finds a way to threaten his peace in the comfort of the abandoned schoolhouse where he can find solace. Both teacher and student can do well at the things they do, even the mysteries themselves, where Chuuzenji is rather reluctant to help Kanna until she gets all the clues, and then he does the problem-solving for her, but reality is often the opposite, as is depicted from the title itself. Sadly, apart from the central two, the other characters are all come-and-go, from just not being developed much (like Kanna's classmates) to less screentime being given to them (like Reijiro Enokizu and Shutaro Kiba), and it is the one aspect the show fails as a whole.

And if you think that the problems don't end there, oh no, we're not done yet. The production from 100studio, being the 2nd work of the rather small studio and its very first individual in-house work, just does not impress. Sure, for basic animation, it does the job alright, but there is nothing that you're going to notice that looks remotely good in any form. It's not a show to coin the word "flashy," but if it's worth watching in its serviceable form, then it's all that will do.

Honestly, HoneyWorks feat. Kaf are given the short end of the stick for performing the show's OP, which I feel is just too overcomposed for its own good. It was a legit surprise hearing the HoneyWorks name here at all, but Kaf deserves a lot better than something like this. As for Sizuk's ED, it's fine and all, but you can tell that by the end of the show itself, a visual circular slideshow is all you get, because there's nothing quintessentially noteworthy about the anime overall.

I don't blame Crunchyroll for missing the license to this at all, but it would've benefited if the executives were lenient enough to give this a wider release, since worse shows than this also get licensed by the corporate monopoly entity either way. But then again, Chuuzenji-sensei is a show where you can cast the "detective" name out of the window easily, because it's just not done service by letting its audience have the time and capability to help harness speculations for future episodes. Instead, it solves its cases by the end of the episodes themselves, limiting any form of interaction that the audience could've had to build discussions at all.

What's a detective show when the mysteries are too easy and simplified and have no quality build-up at all? You'll get something like this, the Grimms Notes version of a mystery that doesn't excite, hype, or thrill anyone at all. For better or worse, this detracts from the reputation of a "detective" show.

!!! Spoiler Warning !!! Folklore Meets Logic The series follows Akihiko Chuuzenji, a seemingly sombre and incredibly talkative teacher with an encyclopedic knowledge of Japanese folklore, Shintoism, and psychology. Whenever a "supernatural" rumour or a "monster" sighting disrupts the lives of his students or the local community, Chuuzenji steps in to dismantle the mystery. Chuuzenji-sensei is like There is no such thing as a supernatural monster; there are only the monsters that humans create within their own hearts. Post-War Atmosphere & Secret Romance The highlight of the show is its 1948 setting. The world is filled with the tension of the American Occupation, featuring GIs in Jeeps andAmerican merchants selling black-market goods.

A particularly unique subplot involves a Japanese school teacher and an American teacher who are secretly in love. Because of the social barriers of the time, they communicated through musical score sheets. They hide coded messages within the notes and staff lines to plan their meetings. This adds a much-needed layer of human emotion to an otherwise clinical show, showing how people found connection amidst the ruins of post-war Tokyo.

Each episode is a lecture Formula where Kanna (the high-energy student lead) finds a "supernatural" problem, runs to Chuzenji-sensei, and he spends the last 8 minutes of the episode delivering a monologue.

Visually, the show is... fine. The character designs are sharp, and Sensei’s "stern face" is captured well, but the animation is static. There are numerous "talking head" scenes where characters stand in one place for extended periods. If you’re coming from the high-production values of modern supernatural hits, this will feel incredibly dated.

Chuuzenji-sensei Mononoke Kougiroku was an OK series that you can binge in an afternoon

This show really suffered from a misrepresentation of synopsis, making it seem like the protagonist, Chuuzenji-sensei, will be some kind of cold detective that would take on serious supernatural cases, when in actuality, he's just mostly gonna be in his hidden room, figuring out supernatural school rumors that will be brought to his attention by Kanna, the active deuteragonist who would actually be the lead of the show. By the time it was clear that this is simply more of a folklore storytelling in the form of mystery, it was too late-- it already seemed like a show that missed its mark. There's been a mixof simple matters and some serious cases the MCs ended up handling, but it wasn't really until halfway through it that the 'folklore' aspect really caught on, making the initial cases the MCs handled during the first half seem so... usual, or at most, something that could be- or SHOULD BE- handled by the local authorities instead of the shut-in teacher and klutz student duo.

Characters (5/10) - Kanna (adorably) dominated the screentime, Chuuzenji-sensei was brooding in his secret room, his hyper eccentric 'husbando' best friend is fun but barely necessary, and his sister decided to be best girl way too late in the game.

Music (7/10): OP and ED, just like Kanna, is so fittingly adorable to what lighthearted vibe of the show.

Art (6/10): Very low quality for this era, but good for me because I have 2000s era bias :P

With all that being said, Kanna's adorable personality alone made this show such a good vibe and easy to watch. For that, the wholesomeness, and the lighthearted fun, I'll appreciate it... still a 5/10 show for me though xD

Watch it if you're a kind, happy soul who doesn't set expectations to the shows you watch.

I really enjoyed this anime. It was one of my favorites of its cour. The characters and the mysteries were inviting. I also liked how it was set at the end of the 1940's and so there were still lingering effects of World War II in the psyches of the characters which I think lent an extra layer to what could have been a run of the mill school ghost story story in other time periods. I would love to see another season. If you enjoy historical fiction, ghost stories, and a solid platonic mentor-mentee relationship, then you'll likely enjoy this anime. If you wantthings to dig a bit deeper, be a bit grittier, or for there to be more than just tales happening, then this might not be the anime you're looking for.

This is a fine anime if you are into mystery solving genre. It is a spooky school mystery anime where the main objective is to solve the 'supernatural mysteries'. Of course most if not all are not supernatural in nature but Kanna does not tell her schoolmates that. Instead she pretends to exorcise or ward of the supernatural elements that her schoolmates think is causing the problem. I did like that instead of power of friendship its a teacher-student duo anime. I also like its realistic in some ways. Even though Kanna is getting credit for solving the mysteries, it reallyis the teacher who is secretly solving most of it. Often we see in school anime 13 year old's are way smarter than their elders. That's not the case here.

But I was a bit bored at one point and skipped two episode to reach the final episode.

My Rating : 6/10 (Okay)

This show is based on a manga by Aki Shimizu, based on the Natsuhiko Kyogoku’s “Hyakki Yakou” novel series of which the author also adapted most of the series into manga. "Chuuzenji-sensei Mononoke Kougiroku: Sensei ga Nazo wo Hodoite Shimau kara" is a prequel to those novels, chronicling the post war years the main character spent as a high school teacher after serving in the army during the war. The prequel is a watered-down version of the novel stories, with less dangerous stakes, and more of a slice of a life bent to the stories. This is intentional because this series was serialized in a shounenmagazine, a more accessible gateway to the “Hyakki Yakou” novels. An original addition to this story is Kanna the high school student who serves as P.O.V. character for those new to Natsuhiko Kyogoku’s characters.

The episodes are mostly standalone stories and sometimes two are adapted in one episode. The milieu is a coed high school, so the stories mostly revolve around Kanna's schoolmates and immediate neighborhood. The mysteries themselves hint of a supernatural origin but are resolved with a succinct explanation by Chuuzenji-sensei. I think mysteries without murder, which contrast with the “Hyakki Yakou” novels that has plenty of it, is an underrated genre.

The weakness of this show is the visual element. The animation is average, and the backgrounds are pretty basic. It doesn't even have that Showa era vibe I associate with shows and movies set in the period. However, it does make the most of its limitations to produce an interesting show that I follow week in and out while it was broadcasting. In fact, I was considering giving this a 6 but I think the last episode was solid enough to push it to 7. It was my favorite episode of the bunch.

I recommend this show for fans Natsuhiko Kyogoku and Aki Shimizu who hunger for more content from these authors. I discovered the “Hyakki Yakou” manga adaptation because of this show, and I find myself wanting more because the manga was never translated officially to English. Some of the novels have English translations, but that's it. Having this anime was like a welcome rain after a long drought. These mystery stories are good, but there are other anime mystery shows with high school protagonists with better production values.

This anime has an immediate strike against it for me which is that it’s a mystery anime. I’ve said before that I’m not a big fan of boiler plate mystery anime, I just tend to find them super boring. Even the supernatural ones, which this is. And unfortunately this one doesn’t have anything in the way of incredibly interesting characters, great comedy, or even incredibly adorable girls to make me like it a lot. I mean the girls are cute, but they’re nowhere close to the pinnacle of cute girls anime because that’s obviously not the point of this show.I didn’t think most of the characters were particularly unlikable, hatable, or annoying, besides a few side characters in episode 1 that we never see again, but the only one where I was genuinely happy when was on screen was the main character, Kanna Kusakabe, but even she wasn’t incredible. She was just the only one with any level of personality, which is below the bare minimum. The anime in general isn’t terrible, it’s nowhere close to the worst I’ve eve seen, it’s just kind of dull and not very inventive. It should be noted that this is a spinoff of an older anime that I’ve never seen. I’m not sure if seeing the previous installment would make me like this better, but I doubt it since this is a spinoff specifically, not a sequel.

we have a Spin-Off Mouryou no Hako that brings us a shonen plot since we will see as protagonist the student Kusakabe, Kanna who will become assistant to the new teacher Chuuzenji, Akihiko in solving the different local supernatural stories to preserve their tranquility in their work plus one or another police case that intertwines with the supernatural story, I like that it remains from the time and does not adapt to the present if not it would make sense since they are based more on the historical context that the plot is set in Tokyo in 1948 they may be easy and unattractive casesbut for the people of that time those mysteries were terrifying and fascinating, I like how they solve the cases, a realistic tone is seen in the handling of characters here you will see teenagers being teenagers and adults being adults the most exaggerated thing you will see in the anime is its comedy, for example the people who commit crimes will appear as villains from classic cartoons and all the teacher's friends all their personalities will be comical since the plot wants you to have a good time without Stress you out

Some people might not like the tone of the series. They might want something more serious with smarter cases and characters with more charismatic personalities. After watching this series, I recommend watching the main series, Mouryou no Hako.

Anime Review: Chuuzenji-sensei Mononoke Kougiraku This anime tells a story about mysteries and Chuuzenji-sensei, who tries to solve those mysteries. However, I personally didn’t enjoy it much for several reasons. Here they are: 1. Mysteries are resolved too quickly I feel like each mystery in this anime gets resolved way too fast, almost like: 1 episode = 1 case. For example, Episode C ends, and then Episode D starts with an entirely new mystery... it just feels too rushed. I felt the same way in almost every episode. 2. Chuuzenji-sensei feels too overpowered, and Kanna is too dependent Chuuzenji-sensei is written to be way too overpowered, he solves everything. Meanwhile,Kusakabe Kanna just feels like a tag-along character. She discovers the mystery, then ends up going straight to Chuuzenji-sensei for the solution...

It’s as if Kanna doesn’t grow at all as a character. Every time she encounters a mystery, she tells Chuuzenji-sensei, he solves it, and then the cycle repeats.

I also don’t really like how Chuuzenji-sensei seems to instantly know the root of every problem so easily. It’s very different from other mystery anime I’ve seen.

Let me compare it with another anime, though I’m not sure how relevant this will be, since they take place in completely different eras, but I’ll focus purely on how the mysteries are resolved, not the time period.

Anime for comparison: Kamonohashi Ron no Kindan Suiri

Unlike Chuuzenji-sensei Mononoke Kougiraku, in Kamonohashi Ron, even though Ron is portrayed as a “genius”, he still needs time to solve each case. It doesn’t get wrapped up in a single episode. Each mystery can take multiple episodes.

Even a character like Ishiki Totomaru has growth and a meaningful role in each case. I realize their roles can’t really be compared directly, Kanna is still a student, while Totomaru is a detective police, so I’m not using that as a point of criticism.

3. Letting the viewers theorize and investigate

When a mystery is allowed to develop over multiple episodes, it gives viewers a chance to get involved to theorize and guess what’s going on based on the clues. It also helps build tension and atmosphere. That’s a big plus.

In contrast, Chuuzenji-sensei Mononoke Kougiraku resolves each mystery in just one episode. That means the audience can’t really participate in the mystery, it’s just: “Oh, a new case? Let’s wait for Chuuzenji-sensei to solve it.” And it’s over.

That removes the thrill. There’s no tension, and in the end, it feels like we’re just passively waiting for the answer without any opportunity to think it through ourselves.

Personal Score: 5/10
