"Rantaro: Chingensai Sameta!!
 * Brick Joke: At the start of the volume 23, Shinbe is supposed to remember a number that indicates a measurement of a warship. He can't. Hundred of pages later, he gives the wrong number and the ship built turns funny.
 * Crazy Prepared: Kaze no Tamazaburou brings two large packages filled with ninja stuffs for one simple mission.
 * Fatal Flaw: Fuwa Raizou is told to be thinking too much.
 * Hurricane of Puns: half of the jokes in the series are these, alternating between this and Incredibly Lame Pun
 * Large Ham: A lot of the villains. Especially Happosai.
 * Loads and Loads of Characters: become this as the story progresses on as more characters from different levels appear
 * Money Fetish: Kirimaru.
 * Mood Whiplash: The nintamas do it on a regular basis.
 * My Name Is Not Durwood: Hietta Happosai, big time.

Kirimaru: Samela Zensai!!

Shinbe: Hietta Namayasai!!

Happosai: *hitting the three nintamas* It's Hietta Happosai, idiots!"


 * Ninja Brats
 * No Fourth Wall: Carrying dialogue bubbles around, talking to the readers, bringing the author inside, among other things commonly occurring.
 * Paper-Thin Disguise: Averted by Hachiya Saburou, whose disguise can't be differentiated with the real person.
 * Shown His Work: Unlike most ninja comics, the ninjas are actually doing things close to what real ninjas did.
 * Status Quo Is God: Taken Up to Eleven with the nintamas going through many Summer and Winter breaks but never graduate or even promote.
