Kamonohashi Ron no Kindan Suiri

Ron Kamonohashi, the best student in the history of the elite Detective Training Academy BLUE, has been living as a recluse since BLUE expelled him five years ago. Moreover, he is forbidden to work as a detective, having barely escaped execution after getting involved in a murder case while he was still attending the school. Ron's situation changes drastically when police detective Totomaru Isshiki, following the advice of a senior colleague, seeks him out for help with a criminal case that has remained unsolved for months. Ron reluctantly agrees to help Totomaru and uses his phenomenal intuition to discover the culprit in less than a day. However, it appears that Ron suffers from a mysterious condition that can cause those around him to lose their lives. To Ron's great surprise, Totomaru manages to save the life of someone whom Ron put in jeopardy.

As the unlikely duo starts solving crimes one after another, BLUE sends operatives after its former student to find out if he has resumed investigative work. Fighting against murderers, rogue detectives, and the Metropolitan Police Department, Ron and Totomaru must join forces if they want to survive and see justice prevail.

Ron Kamonohashi’s Forbidden Deductions is pretty fun. I don’t have too much to say about this season other than it’s a fun buddy cop mystery anime. The dynamic between Totomaru Isshiki and Ron Kamonohashi is a lot of fun to watch and the mysteries that these two solve are engaging and always keep me invested every week. I really like how each new mystery in this season introduces an entirely new set of side characters which helps keep the interactions between the two main characters and the rest of the supporting cast fresh and exciting. This anime also introduces an overarching plotline involving some secret ... organizations and all of this ties into the titular character’s special abilities as well as his backstory, and I’m really invested in it. I assume the second season will focus more on this storyline but this season primarily centers on building and strengthening the dynamic between Isshiki and Kamonohashi. The only major complaint that I have with this anime is that many of the deductions made when attempting to solve the mysteries are mainly from Kamonohashi, and at first I didn’t mind this since Isshiki was an inexperienced detective in the earlier episodes, but Kamonohashi constantly doing around 70-80% of the sleuthing doesn’t really help Isshiki grow and improve his skills, despite Ron giving him all the credit for solving the various cases throughout this season. Isshiki does see some subtle character development, but I’d like for future seasons to not have Isshiki depend on Kamonohashi so much and have him fully solve a case all on his own. Other than that, this anime is very serviceable in being a good mystery series with many fun twists and turns throughout the entirety of the show so far.

Mixed Feelings

Ron Kamonohashi's Forbidden Deduction - To go from one of the most classic franchises to a tongue-in-cheek series that is a precursor to this show, I'm really left with this thought in my mind: does the author REALLY know how to make Shonen works stand the test of time?

To the classic AniManga connoisseurs, I'm pretty sure that the name of Akira Amano is no stranger to you. The female mangaka best known for her series Katekyou Hitman Reborn!, which was featured in Shueisha's Weekly Shonen Jump as one of the top guns alongside the Big 3 at the time, is now, over 20 years later, ... a franchise that I can recommend to anyone wanting to experience a true and pure classic Shonen series. But her later series of the sci-fi adventure ēlDLIVE which (for some reason) was also serialized in the same publishing company's Shonen Jump+ spin-off, garnered a teeny-tiny fraction of her previous juggernaut series, and even with Studio Pierrot's Winter 2017 anime, it really didn't do much for the community expecting something new out of the acclaimed mangaka.

With the failure of ēlDLIVE, while sticking to the same publication platform, comes the brand-new gob-smacking mystery crime series in the form of Kamonohashi Ron no Kindan Suiri a.k.a Ron Kamonohashi's Forbidden Deduction, released in October 2020, with Diomedea's anime adaptation just 3 years later. And the series, despite the recommendation from Takarajimasha's Kono Mystery ga Sugoi! a.k.a This Mystery is Excellent!'s winning mystery writers, with one of them (Sako Aizawa) praising the series as "an "authentic mystery manga for the new era" with its fast pacing, as well as the tricks and logic used to identify the culprit", the anime (and its manga source material) may not be neither bad nor garbage, but is rather bland and mediocre, and a draggy slog to sit through.

What Akira Amano has done here in this series is to take the ever-so-loving tried-and-true formula of Arthur Conan Doyle's Sherlock Holmes and give it her take of the Shonen genre by mashing the personalities of both protagonist (Sherlock Holmes) and antagonist (William James Moriarty) into one person, and that's how we get the series' titular character: Ron Kamonohashi, the aforementioned deranged private detective with an affinity to send culprits to their deaths once the confessions are sounded. This, coupled with the fact that he was involved in an incident where he was found guilty, resulted in his detective license being revoked and him being expelled from the detective training academy, thus isolating him in the process. His saviour, who would get him back into sleuthing, is the rather unremarkable Totomaru "Toto" Isshiki, assigned by his superior Amamiya of the Metropolitan Police Department. Toto looks the part of a typical police detective, though he's rather unrefined and looks cowardly at first glance. That is, until Amamiya requested him to look for Ron, to which he slowly improved his craft, playing the part of Holmes's assistant John Watson, sometimes becoming like Holmes himself, and setting the goal of avoiding Ron's supernatural killing instinct for the culprits.

The problem with the entire series, as much as it's being marketed as a Shonen work, is that it's pretty much bread and butter when it comes to detective works. Sure, you have your usual evildoer group that landed Ron being the bad guy in the first place, but the cases are very cookie-cutter to the point that no matter how the case looks and feels, it starts and ends exactly one and the same. There are slight movements when it comes to Ron's overarching motive to sniff out those responsible for his expulsion, but it's very methodical and slow at the same time. Even the other characters that come onboard to both Toto and Ron's sleuthing campaign are really nothing special, made worse by the fact that Akira Amano chose to stick to the tried-and-true tropes of what works and what doesn't and doesn't even improve on her writing at all. It's just a shame that even in ēlDLIVE that the mangaka herself was entering into new territory that feels cheap but fresh, but in the case of Ron Kamonohashi, it looks as if she has just completely given up on writing a compelling work, the likes of which we'll never see the Katekyou Hitman Reborn! revival once again in time to come.

The aspects where I have the least problems are with the production and music. In-house director Shota Ibata did decent with Diomedea on the production side of things, which looks good, but honestly, this is pretty much what I've expected for anything out of the studio. The music is also decent, with Unison Square Garden and Hockrockb's OP and ED songs, though not particularly memorable.

What's even worse is that we had a detective series in the form of novelist Yuugo Aosaki's Undead Girl Murder Farce last season, and I declared that as my new favourite detective series of all time, being a masterpiece work. So going forward, the detective sleuthing bar is quite high, and no matter how many seasons the production committee decides to pump out of this (since Season 2 has already seemingly been confirmed before the anime started), it'll never change my perception that Akira Amano's newest series, if you take it as anything BUT a detective-themed story, its comedy will definitely either be or not be for you.

Be it as it may, Akira Amano has already lost her magic, and Ron Kamonohashi, is an abject failure on a crime-solving mystery level. Such a shame, but I'm not surprised at all.

Preliminary (6/13 eps)

I recommend watching this if you can turn off your brain! With this you will be able to enjoy 100%!!!!! lmao
First of all, I don't speak English, so my English is a crap, so take that into consideration...
It's going to be my first very very angry and pissed review, so it's going to be long, patience, I have a limit of stupidity that I can accept in stories... okay, let's get straight to the point? worth your time? Only if you can ignore all the stupid people living in the same place as this genius detective. Including his dumb partner, our other protagonist. Why do ... I say this? After watching 6 episodes waiting for a change that never comes, I'm going to explain why I'm saying this!!!
let's go. Things about the plot ahead!!
So, I will talk about some things of the plot now, just read, if u want know the why I said these things..
and if u dont worry about it go ahead.
First, every time Kamonohashi solves a murder case, he forces the guilty people to kill themselves. How? speaking and with a magical eye or hypnotic look (hypinoze, power or whatever), we don't know how he does it or what it is, and neither does he, since he does it unconsciously and without wanting to, and therefore That's why he stopped investigating and solving cases, so he wouldn't kill anyone anymore.
oks, thats great! We already know how it works right away in the first episode! and our dear other protagonist (TOTO) who witnesses everything also right? RIGHT???? (at least it should be like that)! got it? great!
Even though our other protagonist is a talking donkey, he should already understand how this works after seeing it happen 3 times in front of him, right? RIGHT???????????? dammmm this guy is an adult and works as a detective! Did he pay someone to take his tests and solve all his work until he got to where he is now? wtf!! WELL! Even if that was the case, man, I'm not a detective or a genius, but hey, I got it the first time I saw it... and this motherfucker didn't understand how it actually worked until episode 5? wtf! damn it...
So let's ignore the fact this protagonist is THIS STUPID for now and move on...
and all the other people living in this world? Even when he clearly orders people to kill themselves in front of police officers, detectives, or ordinary people, everyone is seeing him doing it, and they clearly see the other person obeying the order.
Then you ask yourself: oh, they saw him do that, so they're going to question him about it, right? RIGHT?????????????????????
no! they simply completely ignore all of his actions from the point he enters this state, no one ever, I say never, questions him about it after preventing the culprit from committing suicide! except in the first episode when the other protagonist (Toto) does this.
anyway, they never question this phenomenon happening in front of their eyes, clearly caused by him.
Who the H E L L in the world wouldn't question something like that? WTF investigators, police officers and people live in this world are doing? THEY ARE BRAIN DEAD OR WHAT???? In other words, we have to accept that everyone simply ignores what happened every time as if it were no big deal (WTF?), and move on with their lives. FUCK THIS PIECE OF CRAP!
And now the last point, which is another thing that really piss me off... (YEAH ANOTHER ONE)
Great, we know that it induces people to kill themselves by talking to them and looking at them, we don't know which of the 2 actually affects the culprit or both (hearing his VOICE OR EYES contact). BUT!!!! we know that whenever the murder case is solved he enters this state to induce the murderer to kill himself!!! right? RIGHT?????????????????????
So our big HERO TOTO, who knows what will happen in these murder cases..... what he says in the first episodes? Let's investigate I will stop you from killing people! great!? right???? RIGHT????????????????????? Yes!! Yeeeeeeeeeeeeeeeeeeeeeeee...... >w<
so you think he will try find a normal way to stop it after saw how it works, right? RIGHT????????????????????? Yeeeeeeeeeeeeeeeee...... >w<
at last should be this way right? RIGHT????????????????????????????
So we like normal persons, think: what could we do to stop him from killing people? What do you think TOTO is trying to do? what you think he is going to do after this? WHAT YOU! a normal person would do? (on my personal opnion we can try many things..) At the end of each solved case, put a blindfold on him so he doesn't see anything? a gag in his mouth so he doesn't say anything? try separately both of then, and later both at the same time to see which one solves the problem? leaving him handcuffed so he doesn't take them both off perhaps? And if it doesn't work, how about putting it out with a blow to the head then? Or what about a sleep aid? and how about the simplest thing? Is it just not letting him witness the resolution of the case in person? After all, he cant solve the case personanlly, so the person who ultimately solves the case in front of people is TOTO.
SOOOOO, which of these things do you think our HERO TOTO tries to do???????
YESSSSSSSSSSSSSSSSSSSS!!!!!!! is exactly what you think!!! Yeeeeeeeeeeeeeeeee...... >w<
none of the above!!! ._.
He just acts every episode like he forgot about his power, and when he starts using it, he tries to stop him? NO! THIS... THIS IDIO...!! THIS SON OF BITCH, THIS MOTHER FUCKER!!! runs towards the killer to try to stop him from killing himself, after waiting patiently our dear brilliant detective to activate the power and say everything he had to say to the guy to kill himself!! he never tries to stop Kamonohashi from talking or doing that, even though this son of a bit.... is on his side every time... wtf... WTFFFFFFFFFFFFFF
This insults my intelligence in such a way that it seriously offends and hurts me, the story is clearly calling me stupid.
THIS CRAP BURN MY BRAIN CELLS EVERYTIME I SEE THIS PIECE OF SHIT...
So if you care about inconsistencies like me, this will bother you! this will hurts u very very bad! ._.
Now if you can ignore this to watch, there will be interesting cases, because yes! The cases and resolutions are cool to watch! and that's the only reason I keep watching it, but this whole plot full of holes hurts me.
And you, what do you think? Answer me, I want to know what you think of what I said!
PS: then why you recommend this crap? and why are u giving this a 6????????? welllllllllllll because like I said, the cases and investigations are really cool... and this is a fact... (but if u cast this aside, and u will get only BIG PIECE OF TRASH dam)! If it weren't for that, this anime wouldn't even be worth a 2 for the stupidity that we are forced to witness...
