reading this volume felt like every time i am forced to do any kind of math. not a pleasant feeling at all. the mystery in this volume was a continuation of the one in the previous volume and it was so confusing trying to follow what the hell they were going on about because it was unnecessarily convoluted.

the resolution of the mystery was extremely anticlimactic and it kind of dampened my excitement for this series so it may be a while before i pick it back up.

I liked this volume for a number of reasons:

1) The investigation of the case and the conclusion were both really interesting. The clues and the final identity of the culprit was quite a surprise.

2) There were some deep philosophical questions on the circumstances behind a crime and I found them a nice addition in this volume.

3) The group dynamics are changing too. The students are placing more trust in each other and I am eager to know how they fare in future cases.

Well, at least the manga is not as drawn-out as the anime. We don’t get dozens of flashbacks of the rescue of chibi Kyuu… but then, we don’t get a single one. Hm, maybe later.

The translation I’m using is, unfortunately, rather bad. This is going to cause issues later, I’m sure. This was better in the anime fansub (both the translation and the limited comprehensibility of the original audio).

Case solved, and fat warning received. The manga and anime, as usual, have small deviations… already.

Ok, so the chapters of this volume weren't that big on action and they repeated thing a lot, BUT Ryu DOES appear a lot, so how can I ever complain?

I probably felt this chapters slower because I remembered the things that happened here from the manga. They are still great cases; I just knew what would happen, so I wanted them to move fast and get to something new (for me).

The last book ends with Ryu Amakusa claiming that he finally understand the tricks used in the impossible disappearance case in Kamikakushi Village, leaving us with three important points to mull over until this fourth installment is published. Are you ready to find out whether your deduction is right or not? Well, do not rush, because the case seems to be unwilling to over soon yet…

THE KAMIKAKUSHI VILLAGE MURDERS

Now that they finally unravel the tricks used to create the mysterious disappearances in Kamikakushi Village, another question linger: who does this repeated murders? And for what? Yet another question linger: where did the dead bodies possibly buried? The answer to the last question is shocking: they are found in the graveyard in Hyotan Village! The only connection between these two surrounded-by-cliff villages is a tunnel that takes thirty minutes to walk, with the spiral stairs in the middle of the tunnel, and the armed guards guarding the tunnel for 24 hours. Clearly impossible to bring the bodies through the tunnel unnoticed. But the culprit did anyway!

“The deadly Kamikakushi event… will happen in Hyotan Village…”


A perfect candidate of culprit has made his appearance: the high priest of the sect, whose face is hidden behind a mask, hands are covered by gloves, and voice is conveyed through sign language. And he predicts the murders accurately! Can the Q Class breaks his iron-cast alibi? Will they manage to solve the puzzle of an infinity symbol which is clearly the key to understand the mystery of these isolated villages? Can they expose the terrible and tragic lie that has enveloped these two villages?

The shocking truth about what actually happened in the two villages is almost nothing compared to the dreadful truth about the identity of the murderer. Rather than hatred, the culprit evokes sympathy. To be misled to believe that what the culprit does is actually to save the world from harm which is not harmful anymore... To realize that all this time the culprit is only a tool to conceal the mistakes that even not the culprit’s doings… So sad.

MEET THE MAIN CHARACTERS

Kyu

He shows another side of him besides his usual cheerful and easily impressed manner: he can be angry and sad when realizing that a murder happens nearby and he couldn’t do anything to stop the crime. But it seems he truly holds Morihiko Dan’s motto that a case will never be solved if the detective gives up.

Megumi Minami

She herself admits that she is the useless one in the case, since everybody else plays the part in solving the case. Her reason to be a detective, namely her admiration towards Morihiko Dan, is not enough a motivation. Moreover, her fear is also another hindrance. Since it is just the beginning of the series, let’s hope that she will have a better character development in the future.

Kintarou Tooyama

Whatever has to do with his family is not to be underestimated. It gives him a better sense of smell, sight, and hearing. Obviously, it also gives him the bravery to jump into danger as easy as blinking an eye.

Kazuma Narusawa

My opinion about him hasn’t changed yet. He is amazing only in front of his laptop. Aside of that, it is still doubtful.

Ryu Amakusa

“It might be possible that the priest you all worship is the real culprit, right?”


He’s so bold, yelling to someone’s face that he is the murderer. I’m not sure whether to praise him or slap him hard for not considering his well-being by uttering such accusation, no matter that the accusation is very likely to be true. He is also the kind of person that will always play by the book and sets aside personal feelings.

Kotaru Nanami

A staff member of Dan Detective School who claims to be the right hand of Morihiko Dan and the watcher of Q Class. He is an eccentric teacher and clearly a master of disguise.

THE MORAL VALUES OF THE STORY

Appearance can be deceiving. Who ever thought that someone who looks the most innocent can be the most merciless and cold-blooded murder?

Human is so resilient. They prove again and again that they can survive any calamity, against all odds.

This was an ending to the story that began in the previous volume.

Lighthearted, Detective School Q Vol. 4 is quite a fun read for general mystery manga fans.

My only challenge with the books is - the array of characters and their development within the stories - though that also serves as the primary strength of this series - the ability for a group of rather variant characters working together in a somewhat, not-so-coherent manner to achieve a common goal.

The author quite elegantly presents some of the challenges of group think and collaboration including how counter-philosophies and ethics clash.

It'll be a series to keep in mind for sure :-)
