- Crowning Music of Awesome: The featured song across the series, Urami Bushi, features unusually visceral lyrics, sung with very emotional (that is, angry and bitter) intonation. The best thing, though, is that they're sung by Meiko Kaji herself, who is to this day a well-regarded Enka singer in addition to her acting career. Nothing like the personal touch.
- Ear Worm: The theme song ESPECIALLY the Shunsuke Kikuchi version.
- Magnificent Bitch: Matsu displays all the main characteristics of one of these. She is highly charismatic, although this usually acts negatively, driving others to hate and/or fear her. She is manipulative, using her enemies fears and pettiness against them whenever she can to compensate for her lack of freedom. She's intelligent, observant, daring and quick to use any opportunity to turn a situation to her advantage. And she certainly has a goal.
- What Do You Mean, It Wasn't Made on Drugs?: The hallmark of the series is its combination of this unexpectedly savage version of the subject matter with repeated recourse to out-of-left-field surrealism.
- The first film's stageplay-like origin story flashback is the first instance of this, with echoes all through the film, created by unexpected coloured spotlighting.
- However, Jailhouse 41 kicks it into overdrive, with a kabuki-like segment and a scene where a bus becomes a courtroom, and the imposition of the surreal onto the real, like the witch, the waterfall or the ending.
- After this, the surrealism quotient drops considerably, but there are still elements of it in Beast Stable's sewer scenes, sound editing and the music-synched stopmotion effect in the bar scene.
