- Anime First: The show has a manga adaptation, focussing on Sakaido solving a case using the Mizuhanome system where he is stuck in a car where the brakes don't work (hence the manga's name of "Brake Broken"). Although the manga, starting in October 2019, predates both the preview in December 2019 and the proper winter 2020 debut of the anime, this is one of those cases where the manga promotes and then runs concurrent with the anime it's based on.
- Dueling Shows: 2 of them in fact. With Case File nº221: Kabukicho and the similarly Mind Screw-y Pet.
- What Could Have Been: The writers had revealed that Hondoumachi as Hijirido was originally intended to wear an Idol Singer outfit, but they decided to change that to her wearing an iconic detective outfit instead. Hilariously, they still wanted to keep the Bare Your Midriff aspect in the show.
