''Ninku'' is a shonen manga series that ran from 1993 to 1995. It was also given an animated adaptation in 1995-96. The series follows the adventures of Fuusuke, Aicho and Toji, along with Toji's sister and a penguin. Long ago, a civil war erupted between the imperium and the ''ninku'' clan. The ''ninku'' were a fierce group of ninja with classical majic ninjutsu, divised into 12 ''ninku'' corps. All three of the guys were captains of their respective corps. Eventually the ''ninku'' were disbanded as the war went sour and now the remaining three are trying to find a way to defeat the imperium.

Although the show was once dubbed it was never released in the US although it did run on AXN in asia. Only the dubbed movie was ever released in the US. Most the episodes can be found at Veoh but only a few of the beginning episodes will be subbed.

This series is notable for being the inspiration behind {{Naruto}}, although some would lean more towards plagiarism, seeing how similar the Rasengan and the Kuatsuken are. MasashiKishimoto even initially drew Naruto in an outfit similar to Fuusuke.

Also has an ongoing sequel known as ''Ninku-second stage'' which started 2005.

Dattebayo has also started to sub the series.

* BlowYouAway: Fuusuke, aka Proto-Naruto. "Wind is my ally. I counter your attack with AIR PRESSURE!"
* CallingYourAttacks: KUATSUKEN!
* TheDeterminator: Fuusuke which is really saying something when a 12 year old boy happens to have more will power than the two grown men he has for comrades.
* DishingOutDirt: Toji is captain of the snake corp and generally uses earth moves that take the form of a pretty live looking giant snake.
* DopplegangerSpin: Used by Fuusuke because he is the fastest of the members and specializes on training the muscle groups in his calf.
* EasternZodiac: The 12 Ninku corps each are named under and animal of these.
* TheEmpire: The Imperium pretty much runs things.
* EverythingsBetterWithPenguins: Hiroyuki the supernatural penguin capable of toxic farts and super strength.
* {{Fartillery}}: Hiroyuki(Fuusuke pet penguin) is capable of releasing explosives farts in the anime.
** This ability originally belong to Toji
* FiveManBand
** TheHero: Fuusuke, of course
** TheLancer: Aicho
** TheBigGuy: Toji, although his ability to fix a plane pushes him onto TheSmartGuy
** TheChick: Rihoko also functions as literally TheLoad, seeing as she has to piggyback on a penguin! in no less than the opening. Heck even the penguin is superhum...just super.
* {{Gonk}}: Fuusuke, who sort of looks like a frog.
* HandSeals: Not very often used except for particularly awesome moves and even then they aren't very many sequences.
* HighlyVisibleNinja: Subverted in that when the clan was still around they covered their faces and wore dark colors. Once they had disbanded Fuusuke wears an ORANGE shirt. And don't even start with Toji.
* HellishPupils: [[spoiler: courtesy of the Tenkuu dragon]]
* HeManWomanHater: Most definitely Aicho, who shows his utter disdain for every time Rihoko goes all fangirl on him.

* NinjaLog: Used in that rare breed of heroic escapes typically reserved for VillainExitStageLeft.
