Synopsis

Despite lacking the skills suited for his role on the Metropolitan Police Department investigative team, Totomaru Isshiki wants to solve murders and help people. Following the advice of one of his seniors, he ventures out to enlist the aid of the reclusive Ron Kamonohashi. Five years ago, Ron was the most promising detective from the illustrious Detective Training Academy Blue; yet for reasons unknown to the public, he sank into obscurity.

Totomaru expects a well-dressed, composed man; but what he gets is a messy-haired and uninhibited eccentric. After years in solitude, Ron barely resembles his former self and he refuses to even hear out the detective. However, as quickly as Ron rebuffs, he flips on a dime and dives headfirst into the current serial murder case.

The true reason Ron withdrew from the detective world was not from lack of desire, but rather from something out of his control—and Totomaru might just be the key for his return to his former calling. Together, the wide-eyed officer and deranged detective tackle each mystery that comes their way.

Preliminary (6/171 eps)
INITIAL THOUGHTS: This is a gag series - not a detective series!

As a fan of the author's Hitman Reborn series, I was very excited to see that she has started a new series as I wasn't a fan of elDLIVE, yet alone a detective series (my favourite genre).

Needless to say, after reading the first few chapters, I can now confirm that this is a GAG series in a detective setting. It is written like a typical detective series in which a police investigator and a smart detective team-up to solve crimes with clues and stuff. The mysteries aren't that intricate or interesting, and the solutions ...

Preliminary (43/171 eps)
This manga is objectively no more than a 4/10 BUT it goes it the "it's so bad it's good" territory so I personally would definitely say it's a 7/10.

I have made a whole video review if you feel like it, you can check that out from my profile.

*I know this is long but I make good point so consider reading*
By far the "best" worse part. It has a classic mystery of the week vibe however I really liked that especially considering the fact that all of the mysteries are between 2 to 4 chapters. It was great to have all of the ...

(Currently, on Chapter 75. My overall thoughts have not changed, only reworded some parts, added more context, and made it more readable.)

I have read Katekyo Hitman Reborn! the anime at least 4 times in my childhood, the manga I've finished 5 times, having re-read it almost yearly. I've read and watched elDLIVE, and re-read it once since I took a break in the middle. Started watching Psycho-Pass (yes, I know, she only did the art), and I can confidently say, that this manga...
...It's meh.

Story: 5/10
If you're looking for an actual detective story, this isn't it, nor if you're hoping for a different type of ...
