Description
The Man Who Likes Ropes, whose Japanese name is Rope Daisuki Ojisan, is a supporting male character in the anime Detectives These Days Are Crazy!. He is a middle-aged man with a bald head and upper body tattoos, and his most defining trait is his fondness for rope bondage, both self-inflicted and as a practitioner.

Background information on the character is limited. He is identified as a member of a loosely associated group known as the YO Four Kings or the Big Four of Yabee Ojisan, a collection of eccentric middle-aged men that also includes the series protagonist Keiichiro Nagumo, Nipple-Tasting Man, and Cross Chest Hair Man. Beyond this affiliation, his personal history is not extensively detailed in available sources.

In terms of personality and motivations, the character is depicted as memorable and eccentric, with a delightfully odd personal backstory. His primary motivation appears to be his enjoyment of ropes and bondage activities, which he engages in willingly and openly. He is one of several quirky, grotesque comic relief characters that populate the series' world.

His role in the story is that of a recurring supporting character and background figure. He does not drive the main plot but appears as part of the comedic milieu surrounding the Nagumo Detective Agency. His presence contributes to the series' gag humor and its emphasis on strange, elderly male characters.

Regarding key relationships, the Man Who Likes Ropes shares an association with the other members of the YO Four Kings, including protagonist Keiichiro Nagumo, Nipple-Tasting Man, and Cross Chest Hair Man. His interactions with the main cast, such as Mashiro Nakanishi, are not elaborated upon in the available information.

The character does not undergo significant development or arc over the course of the series, functioning instead as a static comedic fixture. His notable abilities include his skill with ropes, as he is proficient both in binding himself and in tying others. These abilities are presented as part of his quirky, unsettling charm rather than as serious investigative tools.
