【Kamonohashi Ron no Kindan Suiri】An authentic mystery manga by the author of “Reborn! (Katekyo Hitman Reborn!)”! What kind of story is “Kamonohashi Ron no Kindan Suiri”?

That day, the voice of Isshiki Totomaru, a detective in the Metropolitan Police Department's Investigation Division, echoed through the Police Department. He is pure, but with a lot of loose ends, and is now plagued by a strange case: a rich man who was somehow robbed of his money drowns in a place where there is no water.

“I can't sit still, but I can't find a clue to solve the case either......”
Totomaru was puzzled. Then Kiku-san, a senior staff member and now in the General Affairs Section, said to him,

{center “He might be the only one who can solve it. ”

Totomaru was desperate for any help. So, Kiku-san introduced him to the famous detective Kamonohashi Ron.
Totomaru went to the apartment building that Ron manages and was greeted by......

A skinny man with shaggy hair and no light in his eyes.

Totomaru's impression of Ron was clearly different from what he had heard from Kiku-san. And seeing how lazy he was, Totomaru thought to himself, “There is no way this guy can make a good deduction! However, Ron correctly inferred that Totomaru had visited the shrine to pray for the resolution of the case before coming to Ron, and that Totomaru's actions prior to visiting the shrine.

Totomaruh asked Ron for help, but Ron stubbornly refused.
