Rokujo Ichiko is Hime’s teacher at school from when she was 10-years-old. Despite Kakushi’s efforts to　keep his profession a secret, Rokujo-sensei already knows who Kakushi really is and is even a fan of his gag manga, Tights in the Wind. Things get really interesting; however, when Rokujo-sensei misinterprets the conversation she and Kakushi are having, leading to one of the series’ funniest recurring gags: the romantic tension from Rokujo-sensei and Kakushi’s blatant ignorance in that regard. The two were even centered in the picture taken for Hime’s 11th birthday, but what truly wraps　up the show’s constant pairing of the two is the fact that Rokujo-sensei was the one to tell Hime that her father had regained consciousness.

Mario is the store clerk of a fashion outlet and one of the people who knows about Kakushi’s secret　and how he hides it from Hime. Mario calls Kakushi “Clark Kent” as a reference to his suit disguise, which is not unlike Clark Kent at all. Mario is on this list despite the fact that you could　count the number of appearances he makes on both hands, and this is because of the way he dresses the theme of secrecy in the show with that Clark Kent comparison.

In this way, Mario is like a stranger-confidant of Kakushi’s who even helps him keep his secret! In　the first episode, we see Hime and her school friends exploring the so-called fashion district where scary monsters known as the “oshapi” reside. The term is a portmanteau of the words “oshare”, as　in, fashion, and “people”. It is translated to “fancypeeps”, but the idea as Kakushi explained it, is that such people are fashionable… fashionably terrifying. When Hime and her friends come across Mario’s store, Kakushi is there when he should be at “work”, so Mario covers for him by assuming the　role of the scary monster oshapi and chasing the kids away from the store while gesturing like a monster from a bad movie.

Hime’s friends are a set of intelligent, precocious children who pride themselves in solving the　mysteries that pique their curiosity! The first time we see them in action is when Hime relays what her father told her about the “Fancypeeps”. The group is incredibly tight and they always band together, so when Hime’s father emerged from his coma an amnesiac, the Meguro River Detective Agency　was there to support Hime through the tumultuous emotions that she was feeling, and the chores she did to get away from those feelings. Later on in the last episode, the Agency also assists Hime in retrieving the Kamakura House manga boxes which contained future (at least from Kakushi’s perspective at the time) issues of Tights in the Wind. Their support and friendship with Hime have been instrumental in Hime’s development as a person and they deserve a little recognition!

Naru is an aspiring mangaka who is a high schooler for most of the series. Initially introduced as a　very capable art instructor, she misunderstands Kakushi’s request for art lessons, thinking that he was courting her. The show goes from using Naru for comedy to moving up her importance in the plot. By the time the narrative gets to the present day, Senda Naru is not a mangaka, but rather a focused journalist looking to cover the tragic story of the mangaka Goto Kakushi. Her determination to find out the truth for her own sake, as well as to clear the air shows that her relationship with Hime and Kakushi went deeper than a few art lessons and misunderstandings.

Tomaruin is introduced to the series as the somewhat vacuous editor of Goto Kakushi. His job is to　manage the artist’s workflow and oversee the content of each manga chapter. To make things simple, Tomaruin is supposed to make Kakushi’s professional life easier, but because he is quite ridiculous himself, he never quite gets that right, often setting Kakushi up for scorn or failure. This happens once when Tomaruin decides to put “LOL” at the end of each of Kakushi’s comments on the entries of a major manga competition. The result was that Kakushi was seen as making fun of the entire process when Tomaruin had meant to make his responses appear less serious.

Tomaruin is on this list because of his consistent face-palm moments and ridiculous editorial decisions which leave us in stitches and Kakushi in tears! Tomaruin’s derisive behaviour makes him incredibly annoying, but in the context of the series, his various escapades, snide comments, and complete disregard for Kakushi’s feelings make for great comedy! Let’s not forget the final episode, where Kakushi awakens from his coma with amnesia and Tomaruin comments that it is such a major cliché that wouldn’t even stand in manga! This was just one of many Tomaruin 4th wall-breaks that Kakushigoto throws our way!
