Nintama Rantarou (忍たま乱太郎, Ninjaboy Rantaro) or Rakudai Ninja Rantarō (落第忍者乱太郎, Failure Ninja Rantarou) is a comedy ninja manga series created by Sōbē Amako in 1986. The anime adaptation, Nintama Rantarō, began broadcasting on NHK in 1993. A side-story anime film, Eiga Nintama Rantarō, premiered in 1996. Several Nintama Rantarō video games were also published since 1995.
The series contains examples of the following tropes:
- Accidental Misnaming: Hietta Happosai, big time.Rantaro: Chingensai Sameta!!Kirimaru: Samela Zensai!!Shinbe: Hietta Namayasai!!Happosai: *hitting the three nintamas* It's Hietta Happosai, idiots!
- Adaptation Dye-Job: A lot of characters have different hair colours in the manga than their anime form
- Anachronism Stew: While the series takes place during the Edo era, this trope shows up sometimes, mostly played for laughs. Examples include Rantarou being bespectacled, and a vending machine showing up in one episode.
- Art Evolution: Very evident. Throughout the years, the characters become more cute and chubby.
- Brand Names Are Better: Invoked by Kirimaru.Kirimaru: I start selling Infra-red UnderpantsYamada-sensei: How is this different from normal underpants?Kirimaru: It's not. But more people would buy it if it uses the name "Infra-red"
- 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.
- Canon Foreigner: Several characters were created for the Anime adaptation, most notably Hemu Hemu and Shige-chan.
- 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.
- Loadsand Loadsof Characters: Becomes this as the story progresses on, as more characters from different levels appear.
- 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.
- Re-Release Soundtrack: The Series 1 DVD box sets do not include the first ending theme.
- Shown Their 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.
