A Pen, Handcuffs, and a Common-Law Marriage is based on the manga written by Shinichi Sawaragi and illustrated by Tank Gasuyama, currently serialized in Hakusensha’s Young Animal. The manga has surpassed 400,000 copies in circulation through six volumes as of April 2026. Yen Press licensed it in English, describing the story:

Forty-year-old detective Eiji Kirisame has found maybe the strangest witness of his life: a silent high school girl named Tsugumi Kuchinashi who was at the scene of the crime. Her statements mostly consist of shoddy doodles on a drawing pad, but Eiji is no stranger to piecing together the truth from limited evidence—and besides, it seems like Tsugumi might have a knack for deduction! So he’ll take every page seriously if it might help solve the case. But, uh, does that last page really say…“Marry me?”?!
