Plot

edit

Manga

edit

The story follows an odd-looking 12-year-old boy named Fūsuke, a powerful warrior from the Ninku school of martial arts, who command a style that mixes ninjutsu and kung fu. Before the present time in the story, the Ninku were targeted by an evil empire and the Ninku corps were formed to combat the menace. The names of the corps were taken from the twelve Chinese zodiac animals (Eto (干支)) and each captain of the corps was called the zodiac animal Ninku master (Etonin (干支忍)). Their powers are derived from nature and a specific dragon to their own element, with the Sky Dragon (天空龍, Tenkū Ryū) being the almighty master of all the elements. The Ninku were disbanded by their master before the end of the war and as such, the Empire was victorious and the Ninku became vilified by the Empire as the perpetrators of the war and made attempts to eliminate any surviving members. Three years later, Fūsuke, the young former captain of the 1st Ninku corps and controller of the wind and Hiroyuki, his flatulent penguin, start a journey, searching for the other Ninku captains. However, a new group of Ninku users has arisen and are trying to take over the world. Fūsuke and his penguin must defeat the new Ninku empire with the help of his old comrades.

Anime

edit

Fūsuke, the former captain of the first division Ninku corps journeys across the land with his pet hiroyuki and the hot headed Rihoko to find his Mother who was taken from him at a very young age by the Imperial Army leader Kochin. On his travels, he reunites with fellow captains Toji and Aicho who begin to travel with him in hopes to not only stop the rise of the Imperial Army, but to restore respect to the Ninku students. Along the journey, Fūsuke and the others are tasked with finding and controlling the mystical sky dragons in order to become stronger.

Video games

edit

A number of video games based on the series have been released. Two video games were launched for the Game Boy,[48][49] three video games for the Game Gear,[50][51][52] a video game for the PlayStation,[53] and a video game for the Sega Saturn.[54] Fūsuke is also featured as a selectable character in the Weekly Shōnen Jump crossover fighting game Jump Ultimate Stars, launched for the Nintendo DS in November 2006.[55] Characters from the series also appeared in another Weekly Shōnen Jump crossover smartphone game Jumputi Heroes, released for iOS and Android in 2018.[56]

Reception and legacy

edit

The Ninku manga has had over 9 million copies in circulation.[16]

In a fan poll posted by BIGLOBE in 2012 about favorite Weekly Shōnen Jump anime adaptations, Ninku ranked 45th out of 50 anime adaptations,[57] and 40th out of 60 series in a 2019 poll conducted by Goo Ranking of "’90s Anime That Deserve Remakes".[58]

John Oppliger of AnimeNation attributed the low popularity of the Ninku anime series to its lack of compelling narrative development and the sequential lengthy story arc structure that make other shōnen action series like Naruto, One Piece and Bleach popular. He praised the characters and animation of the fight sequences, but considered them repetitive and he stated that the show does not encourage much viewer loyalty.[59]

In a review for the Ninku/YuYu Hakusho Double Feature DVD release, Chris Beveridge from AnimeOnDVD praised Ninku: The Movie for its fight sequences and animation, but recommended this release only to fans of either series.[41] Mike Toole of Anime Jump in his Ninku: The Movie review stated: "Aside from the engaging story and great fight scenes, there are a few other good points about Ninku."[60]

Ninku has inspired artists such as Masashi Kishimoto of Naruto fame, who used to copy Kiriyama's drawings in his studying to become a manga artist.[61]
