A Pen, Handcuffs, and a Common-Law Marriage Vol 1 Review

Themes of unlikely couples getting together to solve crimes are not exactly unheard of in the entertainment industry, but Shinichi Sawaragi truly manages to turn the trope on its head. The duo this time consists of a middle aged single detective and a mute high school girl, while the crime solving soon becomes intertwined with romance, even by the end of the first case. Even more surprisingly, the one who initiates it is not the older man. Buy This Titleby clicking on the image below Forty year old detective Eiji Kirisame is a detective in his soul, meaning he cannot actually relax if he does not have a case to think about, an obsession that has even led his colleagues to mock him despite his success in the field. One day, however, during his investigation of a mysterious individual causing trouble in an old arcade, he stumbles upon the strangest witness of his life: a silent high school girl named Tsugumi Kuchinashi who was present at the scene of the crime. When a body falls from the roof during their initial meeting, everyone considers it a suicide, but not Eiji, who believes there is more to it. With the help of her statements, which mostly consist of shoddy doodles on a drawing pad, Eiji manages to learn more about the incident, while it soon becomes apparent that Tsugumi has a knack for deduction. At the same time, she also proves remarkably skilled at blackmailing Eiji into doing whatever she wants. The two soon manage to solve the mystery, but by the end of the first story in the book, Tsugumi has already confessed to Eiji and has even asked him to marry her. Shinichi Sawaragi has come up with a story that is half crime solving and half romance, with the way the two complement each other emerging as the narrative’s strongest element. Agatha Christie vibes are evident throughout the cases, yet the fact that the investigations are conducted by a duo, and particularly that Tsugumi is the one who usually figures out the culprits and what actually happened, adds a humorous twist, especially since she communicates her deductions through complicated, badly drawn doodles that Eiji must decipher. Consequently, the comedy works quite well, particularly through the role reversal dynamic, as the true victim here is essentially the forty-year-old policeman while the perpetrator is the young and quite beautiful girl. At the same time, the focus on the bureaucracy of marriage in Japan adds another interesting layer, at moments bordering on educational due to the level of information presented. Furthermore, the contrast between the two protagonists works particularly well, since it extends across every aspect, including age, appearance, and mentality. Eiji appears kind and somewhat naive, whereas Tsugumi is calculating and cutthroat, yet their shared knack for solving crimes ultimately turns them into a surprisingly fitting duo. The artwork by Tank Gasuyama is also on a notably high level. The character design, both of the protagonists and of the numerous supporting characters who appear throughout the pages, is particularly impressive, with appealing and detailed lines that allow each figure to stand out. Moreover, the attention to detail in the backgrounds is remarkable, with the Ferris Wheel in particular standing out, resulting in one of the most visually accomplished works among the manga releases of 2026. Although somewhat naive in its crime solving aspect, “A Pen, Handcuffs, and a Common Law Marriage Vol 1” offers a very rewarding combination of romance, crime, and comedy, while also generating considerable interest regarding how the relationship between the two protagonists will evolve in the upcoming volumes.
