The Poet and the Lunatics

"One must never place a loaded rifle on the stage if it isn't going to go off."

I like this cute cover!

Publisher Tokyo Sogensha has been offering a fantastic platform for mystery writers who haven't been published yet for decades now with the prestigious Ayukawa Tetsuya Award: the award includes a publishing contract for the winning manuscript, and writers like Ashibe Taku, Asukabe Katsunori, Aizawa Sako, Aosaki Yuugo, Amon Junichi, Ichikawa Tetsuya, Ichikawa Yuuto, Imamura Masahiro, Houjou Kie and many more have all made their professional debuts by winning this award aimed at novel-length works. In the meantime, Tokyo Sogensha has also provided a platform for short stories, which would also be rewarded with publication in their literary magazine. 2022 was the last time this award was called the Mysteries! Newcomer Award, as it is now called the Sogen Mystery Short Story Award. The last winner of the Mysteries! Newcomer Award was Mamon Kouhei, with the short story Lunatic Retriever. This short story is included in Mamon's 2024 short story collection Bokura wa Kaishuu Shinai ("No Pay-Off for Us", 2024), which provides a nice showcase of his mystery plotting skills, as well as his talent for writing characters.

The book opens with Gaitou Interview ("Street Interview"), which offers a seemingly harmless mystery: Kirito is approached by classmate Fujiwara, who needs some help, and Kirito is known for having a very keen eye for details. Fujiwara's sister was recently interviewed on the street about a few topics, like the trend of younger people not reading newspapers anymore. Her sister thought the interview went well, but after it was broadcast, people on the internet started bashing her sister for giving stupid answers, and some even just bad-mouthed her appearance. Fujiwara doesn't know what Kirito can do, but hopes he can somehow make it stop. After a careful examination of the street interview video, Kirito is however indeed able to miraculously stop the bashing. This is a unique kind of mystery, as it doesn't involve any real crime, but it is set-up in a convincing manner, even if some of the clues are introduced too close to Kirito's proposed solution to resolving this matter. It's a mystery you could imagine happen in real-life, and I really like how the story eventually wraps back to Kirito's own backstory of how he became known at school as a kind of detective.

Kaeru-Goroshi ("The Murder of a Frog") is about the comedy duo Frogs in the Well, consisting of Shougo and Mitsunori.  Shougo is introduced to Miki, a great fan of the duo, via a mutual friend, and the two start seeing each other more often, eventually leading to them dating officially. While the two comedians have been working hard on their act, they never had their big break, until they finally manage to win first place in a prestigious comedy contest, which results in them getting more offers for appearances on television. The two are not used to their new succes, getting drained by the constant stream of gigs and to make things worse, Shougo is suddenly rejected by Miki, who, despite still being fond of him, somehow can't stand being with him anymore. It's during this period a comedian from the same agency, who has been in the trade for a very long time without any succes, finally wins his first contest. Masuoka Hideki never had much success, but he was always super nice to his juniors at the agency, so everyone is beyond happy for him, and they all gather at the offices of the agency to celebrate his long-awaited award. They all have something to drink and after a while, people walk in and out the room to make phone calls and smoke, but when Mitsunori goes out on the balcony on the third floor, he spots a dead Masuoka on the street below, and lying next to him, is a squished frog. Considering Masuoka just won an award and had his big break that very night, it doesn't seem likely this is a suicide, and suspicion falls on all who were in the building at the moment, but because it is not clear at first when Masuoka left the room and died, it is difficult to establish who was where when, and therefore who has an alibi or not. After reading the first story, I had mistakenly assumed this book would not feature murders at all, so this was a pleasant (?) surprise. Mamon spins a very Queen-esque whodunnit tale, where you use the various physical clues sprinkled across the tale to cross out suspects off the list, and there are some clever twists hidden in this process too, but what is the most memorable about this story, is definitely the motive for the murder. While a motive is a very subjective thing (one can find a motive satisfying, while someone else not at all), I find Mamon's efforts in presenting this aspect too as a fair-play mystery, and the way he set-up the motive with foreshadowing quite memorable. Considering how the whodunnit-part clewing went and the way the motive was so thoroughly foreshadowed, I can easily imagine this same short (very short!) story be fleshed out into a full novel, and it would've worked as well.

Tsuisou no Ie ("The House of Memories") is a very short story, where a father and his two adult children visit the home of the grandfather, who recently passed away. While going through his stuff, the narrator realizes something odd's going on: he has vivid memories of visiting his grandpa's study, which had bookcases filled completely with books. He hadn't visited his grandfather at home for many years, especially not because they had a fight a few years ago, but he knows his grandfather kept on buying books and that he never ever sold his books... But where have all the books his grandfather had bought after he last visited him, have gone to, as the bookcases in the study were already completely full back then? Cute little mystery that may have a very simple solution, but it just works very well with the theme of childhood memories.

Hayami Shirou wo Oikakete ("Chasing after Hayami Shirou") is a two-party mystery, where the narrator first tells how his classmate Hayami Shirou once saved him from a false accussation at school: trash had been thrown around the pool, and because the narrator had a fight with the teacher of the swimming club at the time, he was accused of the vandal act. Hayami however very ingeniously, and swiftly proves who the real culprit was. The narrator and Hayami now go to the same high school, and Hayami's talents are once again needed, when the football (soccer) club find their storeroom ransacked, with balls and other equipment stolen. The stolen items however are found the following day, having been left somewhere on the school grounds. The way Hayami deduces who the culprit is, and why, is clever and I do like the clues are based on physical senses that usually aren't featured as strongly in written fiction, though at the same time, that is also why the story kinda falls flat for me, as we read a lot about these senses, but while your mileage may vary, I did find it hard to believe how "exactly" for example a character could recognize a lingering smell. I do like the little twist at the end of the deduction process that allowed Hayami to point at the one and only culprit, and the motive works well in this school setting too.

Lunatic Retriever is set at a college mixed dormitory, which has one 'famous' inhabitant: Yoshida Haruka won a literary award at age 20 and has been publishing books these last two years. She's also quite arrogant and doesn't mingle much with the other students living in the dorm. However, that doesn't mean her death isn't a shock. On the day a solar eclipse happens, she is found dead in a storeroom inside the dorm. The storeroom was originally a smoking area inside the common room, with two doors (one opening in, the other door opening out). Before the eclipse, people tried going to the storeroom to get something, but found both doors locked for some reason. After the eclipse, the students find it odd the doors are still closed, so they force the doors open. They not only learn the doors were "locked" because they had been taped tight with duct tape, they also find a dead Haruka lying on the floor, as well as a burning stove. The room being taped shut and the burning stove suggests Haruka committed suicide by carbon monoxide poisoning, but on the other hand, they also are of the opinion Haruka would be the last person to commit suicide. But if it was murder, how did the murderer escape the taped storeroom? This is a very dense story, with a lot to offer: a taped locked room, Ellery Queen style deductions to determine who the murderer is, and we even have a solar eclipse... Because of the clue density, we even have room for multiple people presenting their theories, and interestingly, I think that in terms of the locked room mystery, the final solution isn't even as impressive as the earlier ones. What is really memorable about this story however, is the ending, when we are confronted with what is thematically an absurdly shocking revelation. It is a funny, meta-level observation that in a different work could have catastrophic implications, but it works in this short story setting and gives you some food for thought regarding the mystery genre, while also still functioning as a mystery story itself. The theme, in hindsight, can be found in other stories in the volume too, which wraps things up nicely.

This is the first time I read anything by Mamon Kouhei, and while I am generally more a fan of short stories, and I did enjoy the short stories found here, I have to admit they left me wanting for more, for stories that show the same type of plotting, clewing and ways in identifying whodunnit, but with more room for depth and that is also the case for the motives, there are some really originaly character motivations at display here that result in interesting mystery settings, and I'd love to see Mamon for example trying to do a longer detective novel with such themes. So I'll keep an eye out for Mamon's future output!

"Yellow Yellow Happy" (Pocket Bisquits)

No, this book is not set in a place where rocks levitate...

It has been three years since the traumatic events at Katsuragi Teruyoshi's family home, and now the great detective and his best friends Tadokoro Shinya and Mitani Rokurou are all studying at different universities, all having an idea of their future. They still see each other often, but they have not travelled together in ages, however, exceptions are made for special occassions: Katsuragi and Tadokoro have received a letter from Asukai Hikaru, the former high school student detective whom Tadokoro looked up to when he was young. A few years ago, Katsuragi and Tadokoro met her, now in her late twenties and working as an insurance agent, at the house of  mystery author Takarada Yuuzan, where they were confronted with a horrible murder. Katsuragi and Hikaru had clashed about their views about what a detective is, so Katsuragi and Tadakoro are surprised to learn she had written them a letter. She informs them she's going to be married to Dotou Kouki, the son of Dotou Raizou, the world famous multi-disciplinary artist, especially known for his paintings, sculptures and architecture. While Kouki is "a normal guy", his sisters have inherited their father's artistic talent, with Yukie being an accomplished illustrator, Tsukiyo a sculpter and Kanon a singer. Because of Kouki and Hikaru's engagement, they're going to have a rare gathering on the last day of the year at Raizou's home the Wasteland Manor: a house with four towers Raizou himself designed, located in what is basically a small, square valley, with the house surrounded completely by four rock walls. 

Raizou turns out to be a friend of Takarada Yuuzan, who has passed away since. It was Raizou who designed the house of Yuuzan, and in exchange, Yuuzan had written a mystery novel set in Raizou's home. It is this unpublished manuscript that worries Hikaru, prompting her to contact Katsuragi and Tadokoro. It appears Hikaru's presence at Yuuzan's manor three years ago had not been a coincidence, but set-up by Yuuzan, and she fears she's being manipulated again by this unpublished manuscript of Yuuzan. She hopes Katsuragi and Tadokoro will come to the house, as her "relatives" and see if they can get their hands on the manuscript and see what is hidden within the pages. Katsuragi has no intention of meeting Asukai again, but he agrees to at least join Tadokoro and Mitani on their way to the house. The three young men meet with Hikaru and Kouki outside the house to discuss what they'll do, but then they are surprised by a heavy earthquake. While they are all unharmed, the road has collapsed and trees have fallen on the road, blocking it completely. Very conveniently, Katsuragi alone finds himself on the outside world side of the road, while the rest are now trapped on the house-side of the road. Katsuragi says he'll go to the nearby town and stay there, while Tadokoro and Mitani will go with Hikaru and Kouki as planned. 

Things soon take a turn for the worse however. Tadokoro and Mitani are introduced to the rest of the family (as well as two other guests), though none of the Dotous seem very interested in them. Everyone is shocked to learn they have been cut off from the outside world, but they have enough supplies to last for about four days. And while there are occasional aftershocks, the house itself is sturdy enough to withstand the violent movements. However, the following day, patriarch Raizou is found dead in the courtyard of the house: the elderly man has been shish-kebab'd on a statue of a knight holding a sword up high and what's more: the murderer has left no footprints in the wet garden. When they go looking for Yuuzan's unpublished manuscript in Raizou's room, they find someone has taken it: is it a coincidence a manuscript about a murder case happening in this house is now missing? Meanwhile, Katsuragi has barely managed to find a room in the only inn in town, which is swarming due to the sudden earthquake and trains not running anymore. His attention is soon drawn to his roommate Ogasawara Tsuneharu, who is acting rather suspicious. Of course, Katsuragi has no way to know that Ogasawara is planning to kill the proprietor of the inn: not because he has a motive to kill her, but some hours ago, Ogasawara had agreed to do a murder exchange: when he was not able to go to Raizou's home due to the road collapse and fallen trees, a woman called out to him from the other side of the blocked road, who offered to kill Raizou for him, if he instead kills the inn proprietor for her. Can Katsuragi and Hikaru solve all the crimes happening in and outside the house in Atsukawa Tatsumi's Koudokan no Satsujin ("The Murder in the Earthy Yellow Manor" 2023)?

This is the third book in the series which now bears the name Manor Quartet, which obviously suggest this series will be four parts in total. The first book had fire and the summer as its theme, the second water and autumn and this third book revolves around earth and winter. So yes, that suggest the final book's theme will be wind (air) in the spring. A murder in a house during a typhoon? Anyway, I enjoyed the previous two books about Katsuragi, the young detective who has the ability to sense people lying to him, and while I had not read the premise of the book before, I was pleasantly surprised to learn that Asukai Hikaru from the first book returned too in a prominent role, so once I got started with this book, I had gone through it really fast.

The book takes on a rather interesting structure: the first third of the book is actually an inverted mystery: we follow Ogasawara Tsuneharu as he makes his way to the Wasteland Manor to kill Raizou, whom he hates for a very personal reason, only to find the road collapsed and blocked by fallen trees. When he grumbles out loud he now can't kill Raizou now, a woman calls out to him from the other side of the road. While they can't see each other, she offers to kill Raizou instead of him, if he then kills the propriator of the local inn. The woman suggest she'll kill Raizou first and use a flare signal so Ogasawara will know she has succeeded in her task, after which he'll kill the proprietor. Ogasawara accepts the offer for a murder exchange, and arrives at the inn, but can only stay he shares a room with Katsuragi. And so Ogasawara slowly starts to plan his murder (luckily, he was already planning to kill Raizou so he has things like poison with him). But as this is an inverted detective, we of course see how Katsuragi slowly starts to suspect his roommate isn't just some innocent guest. But how did he figure it out? This part is fairly short, but I do like the clewing Atsukawa employed to allow Katsuragi to get on the trail of Ogasawara. We know Katsuragi starts to have his suspicions very early on, but the clues that allowed him to zero on his roommate are fairly clever hidden. In the aftermath, Katsuragi learns about the murder exchange, finally realizing his friends Tadokoro and Mitani may be in danger, as there's a murderer in Wasteland House. 

At this point, the book jumps back to the last day of the year, and we now follow Tadokoro, who together with Mitani visit the Wasteland House. Kouki's sisters Yukie, Tsukiyo and Kanon seem not interested in the two men, nor are the two other guests (an art broker and Kanon's manager), but Raizou himself seems interested in Tadokoro, as Raizou is aware Tadokoro and Katsuragi where involved in the incident in the house of his friend Yuuzan, and Raizou also seems more interested in Hikaru's past as a high school student detective, rather than as his future daughter-in-law. The following day however, the man is found dangling from the sword of the knight statue in the courtyard, but how could anyone have lifted the victim and stabbed him on a five-metre high sculpture? As there's no landline phone and for some reasons, their mobiles don't have any reception, all they can do is wait until the road's been restored or outside help comes via some other way, but they don't have much time, as more mysterious happenings occur, from sightings of a masked butler who can escape from a tower room with only entrance even though they were being chased by Tadokoro and someone being shot inside another tower room, even though it was locked from inside and the only window in the room looks out... on a rock wall. With Katsuragi not present, and Asukai Hikaru having sworn off ever playing detective ever again, Watson Tadokoro finds himself forced to be the Holmes himself this time...

In Gurenkan no Satsujin and Aomikan no Satsujin, the respective themes of a mountain fire, and a flooded river added a note of excitement to the mystery: like Ellery in The Siamese Twin Mystery, it wasn't just that Katsuragi and Tadokoro found them having to deal with a musterious murder committed in a house, they also had to deal with an unstoppable force of nature, a force that also had its influence on the murders. In Koudokan no Satsujin, we have one major earthquake at the very start of the book, followed by unpredictable aftershocks, but I have to admit I found the theme not as strong here as in the previous books. The initial earthquake creates the closed circle setting, and also sets up the murder exchange, but from that point on, we just have aftershocks happening now and then. They don't really serve as a constant threat, as they come and go swiftly, and it's not like you can predict them. The earthquakes are not a theme that permeate throughout the novel, only popping up now and then, so that kinda weakens the "earth" theme, even if the couple of themes they do feature in the mysteries, they are integrated cleverly.

 What you can't accuse Atsukawa of, is him skimping on the mysteries though. We have Raizou skewered on a sword in the courtyard, even though there are no footprints left in the courtyard, even though rain had softened the ground last night. We have masked butlers being chased into rooms with only one entrance and disappearing from those rooms. We have a body which appears in a room, even though everyone has an alibi for the time between the discovery of the body, and the last time people visited the room, and many more. What I do like is that a lot of these mysteries do share a common thread, used in a few ways. I have to admit I have read so many of these books by now, I found the big trick a bit easy to guess because I have seen similar ideas quite often, but the execution is well-clewed and because Atsukawa utilized the idea in various ways, it feels fairly substantial, rather than a one-trick pony. The earthquakes in return are featured now and then in the mystery, for example forcing the murderer to do something in a certain manner, or the earthquake creating an unforeseen situation for everyone. As mentioned before, the synergy between this 'force of nature' theme and the mystery isn't as prominent as I had hoped, but when it's done, it definitely presents interesting parts of the mystery.

That said, I do find the whodunnit rather disappointing. The first part is an inverted mystery, so of course who the culprit is, but Ogasawara himself never learns who his partner in crime is, so we don't know who the murderer inside the house is. However, the way Atsukawa planted the clues to point to the murderer are a bit too obvious. While from an in-universe point of view, it makes sense it takes some time for the detectives on both sides to catch up as you need information obtained from both in and outside the house to solve everything, it doesn't mean the reader isn't already in possession of that knowledge, and it makes the attempts to present false solutions feel a bit weak, as you know the big elephant in the room hasn't been addressed yet. 

Overall though, I do like how this book is set three years after the previous books, with a more mature Katsuragi Teruyoshi who has learned to deal with his trauma gained in the previous two books, and we see how that also helps Asukai Hikaru, who has her own trauma. I'm not really that interested in character development, but for those looking for that in a detective character, you can definitely find it in this series, and what I do like is how Katsuragi's character does influence his detecting style a lot: it's his experiences that leads him to act like he does now as a detective, so in that sense, I do like seeing the change in him, as it's directly reflected in the way the mystery is plotted and how Atsukawa decides to have the story solved.

Koudokan no Satsujin is overall a solid third entry. While the earth theme isn't as strongly present here as the force of nature themes in the previous two books and it is overall a bit simpler, I do like the twists Atsukawa presents here, like having an inverted mystery section, and focusing on basically three detective figures in Katsuragi, Hikaru and Tadokoro. Can't wait to see how the last volume will wrap things up!

The Bear Detectives

Look for the bare necessities, the simple bare necessities
Forget about your worries and your strife

"The Bare Necessities" (Phil Harris, Bruce Reitherman) 

While I am not in direct contact with current members of the Kyoto University Mystery Club, as a former member I do still follow their social media. Personally speaking, my favorite activity at the club were the sessions with whodunnit/guess-the-culprit scenarios: these were short mystery stories written by club members which were clearly divided in a "problem" and "solution" part. The idea is that everyone is first handed the problem part, which traditionally ends with a Challenge to the Reader. The participants get about 45~60 minutes to read the story and (logically!) figure out who the culprit is of the story. If you think you know whodunnit, you can discuss that with the author and they'll tell you whether you got it right or wrong, and after the initial session is over, the author hands out the solution parts to everyone. In a way, the stories do tend to be a bit formulaistic in form, often following Queen-style deduction methods to prove who the culprit is (the culprit knew fact X. Y is proven to not have known fact X, therefore they can't be the killer), but it's exactly the type of mystery story I love, and it was great seeing different members using this form to tell different tales. And while these stories remain "private" for the club generally, I still liked seeing the KUMC social media account briefly tweeting about once in a while about how they did this or that story this week, and how it was received at the session.

Because of that, I still remember how last year, the KUMC account posted how one of their members had written a Danganronpa fanfic as a whodunnit scenario. As someone who enjoys the quirky mystery game series, I was of course intrigued by this concept, as at least in the year I was at the KUMC, people always opted for "original" settings (i.e. not based on existing IPs). But as with most of these stories, I assumed I'd never get a chance to ever read it as I wasn't an active member anymore, and you generally only get to read the story the time it's read at a club session. However, a few weeks ago, I learned the author, Kunou Junki, had actually self-published their fanfic late 2023, selling it at doujin markets. Which was cool, but again, I wasn't really in the position to visit those doujin fairs to pick the booklet up. It was apparently received pretty well though, and Atsukawa Tatsumi even mentioned the story in his ongoing column on mystery fiction, praising it as a whodunnit scenario and as a Danganronpa fanfic. But then.... a few days ago, Kunou announced they were finally selling the fanfic via Booth. So I finally got to read it.

Danganronpa FF - Ame no Kigou, Soshite Happy Birthday ("Danganronpa FF - Rain Code, and Happy Birthday", 2023) is set at the aptly Doujin Academy, where a group of students, each being extremely skilled in a very specific field, are held captured by Monokuma, a cute-looking, but horrifyingly sadistic robotic bear who has set up a game of death among the students. If a student kills a fellow student, a class trial will be held, in which the participants must decide (vote) on a culprit. If the students manage to identify the real culprit, the latter will receive "punishment" (be executed) and the game will continue (more of these rounds) until there are two survivors left, who are free to go. However, if the real culprit manages to elude suspicion at the trial, they are the one will be released, and all the rest of the students will receive "punishment". Monokuma has been feeding the fears and desires of the captured students, making some of them desperate enough to want to kill their fellow students in an attempt to escape Doujin Academy, but fortunately, up until now, the remaining students have been able to correctly identify the real culprit each time, allowing the rest to survive while the real culprits have been executed. At the start of Danganronpa FF, about half of the initial group of students is already dead, either having become a murder victim, or having been executed as a murderer.

The story is told from the POV of Yomikura Suzu, the Ultimate Narrator, who has been acting as a kind of Watson to Aizawa Seishun, the Ultimate Detective, who has been the MVP in the class trials until now: not only has he been solving most of the murders, he is also trying to figure out a way to escape from Monokuma's prison. After the latest execution, Aizawa hopes to set a plan in motion that will allow them to go against Monokuma, and he decides to rope in Yomikura as his accomplice. While the gymnasium is closed off during the night (22:00 - 08:00), all other rooms in the school are accessible, and Aizawa has found out the dressing rooms in the corner of the lecture hall, in front of the passage to the gymnasium, do have cameras, but no microphones, and are also completely soundproofed, so he spends the whole night discussing his plans with Yomikura there, assured Monokuma can't overhear them. When they leave the dressing room the following morning however, they are shocked to find two murdered bodies lying in the lecture hall and that they have been penetrated with a spear. There's also a bloody trail leading from the gymnasium, through the passage, to the lecture hall. A new game of life and death begins, as the remaining students need to figure out who the killer is, or else they themselves will be executed.

Save for the occasional pastiche, I generally don't read fanfics, so I have no real idea of what the standard is, but I sure found Danganronpa FF to be a very effective one. It starts already with the great cover art and the next page introduces you to the various school rules of Doujin Academy, which will be a familiar sight to those who have played the original Danganronpa games: there are the general rules that explain under what conditions a student can escape the school, but also rules about the night time, about ownership of student notebooks and even about how many people a killer may kill (as in: you can't just kill everyone and win the game in that way.). Most of the rules are exactly the same as the games, so it really feels like this is a story set in that world, even if we're now at Doujin Academy. While the characters are original, the characters have concepts that would seem to fit perfectly in the Danganronpa world, from the Ultimate Narrator, to characters like The Ultimate Twin, the Ultimate Ninja and the Ultimate Mountaineer. This story is set after half of the cast has already been wiped out, so it's a bit of a shame some characters are only mentioned briefly by name only, and I'd love to have seen more of them (I wonder of Kunou is planning more stories/"chapters" set in this world?). However, I do have to say that for the most part, you don't really need much prior knowledge of Danganronpa to enjoy this story as a tale of mystery: the essentials are explained adequately (especially with the rule book at the start of the booklet) and ultimately, the mystery really revolves around these specific murders, committed at this specific point in the ongoing story, so no knowledge is necessary about what happened before, or what happens later or about Danganronpa in a meta way. In Danganronpa terms: this is a specific chapter, with its own case.

As a pure whodunnit mystery, I have to say I was surprised how dense this was. It's been a while since I did a 'real run' of a whodunnit scenario, so I'll be the first to admit my deductive senses aren't what they used to be, but Danganronpa FF seems about a full step more complex than the usual KUMC whodunnit scenario, making it unlikely anyone could have gotten all the points within the usual session time (though perhaps they held a longer session than usual). So yeah, this is a really deep whodunnit story following the Queen format, where you can logically deduce who the killer is by identifying criteria the killer must answer to, and then figuring out who of the suspects answers to all of those criteria. Some of these criteria are relatively easy to notice, allowing you to cross off some names early, but others are really cleverly done, and I am the first to admit that I wasn't even close to the answer model provided by the detective at the end. There are quite a few (very devilish!) twists and turns in the long deduction process (which is why I think it would have been difficult for someone to solve all of the story during a normal club session), but for Ellery Queen logic-lovers, this is really great stuff  and I love a lot of the logical processes shown in this story (the initial step alone of the long elimination process is already really good!). What is even more commendable is how cleverly Kunou makes use of the Danganronpa setting. A lot of the things pulled off here in terms of logic only make sense in a Danganronpa-inspired world, with the school rules and Monokuma antics and stuff like that. So I really agree with Atsukawa here about Danganronpa FF is satisfying as both a mystery story, and a Danganronpa fanfic.

The third act of Danganronpa FF wasn't originally part of the scenario presented at the KUMC, as after the initial murder problem and the subsequent solution part, we are treated to what is basically an in-depth essay on the Danganronpa games as mystery games. If you have played the games (or you don't care for spoilers at all), there are some interesting points made (ha, I hadn't expected Kunou to quote Morooka's academic work on shin honkaku mystery and games!), but it is certainly a part that 'takes you out of the story', so your mileage on this closing part may vary. This part has no direct influence on the logical parts of the mystery, so you could choose to ignore it if you wish to do so.

At any rate, I did really enjoy Danganronpa FF - Ame no Kigou, Soshite Happy Birthday, as both a really well-plotted whodunnit scenario as well as a mystery story written with a lot of love for the Danganronpa franchise. Danganronpa FF was apparently also a reason why Kunou was asked to pen an original whodunnit story for the Mystery Carnival event of publisher Seikaisha held last week. I haven't read that story, but I do hope I get to read more of Kunou in the story, as what I have read here really makes me curious to what more they can come up with. Hopefully, we'll see more of them in the future!
