The hidden manga lineage that birthed the world of Naruto
In short: Before the global phenomenon of Naruto, there was Ninku. While it remains a cult classic with a modest ranking in popularity polls, its influence is foundational. The creator of Naruto even admitted that his iconic series exists primarily as a spiritual continuation of this 1990s martial arts epic.
Ninku, written and illustrated by Kōji Kiriyama, first appeared in Weekly Shōnen Jump in June 1993. The story centers on Fūsuke, a 12-year-old warrior from a school of martial arts that blends ninjutsu and kung fu. The narrative follows Fūsuke and his supernaturally powerful, flatulent penguin, Hiroyuki, as they search for former comrades after their order was disbanded following a war with an evil empire. The series features a unique power system where captains derive abilities from nature and specific dragons, such as the Sky Dragon, which governs all elements.
Despite its cultural weight, Ninku has faced challenges in mainstream recognition. In a 2012 fan poll, it ranked 45th out of 50 favorite Shōnen Jump adaptations, and a 2019 survey placed it 40th out of 60 series deserving of a remake. Critics have attributed this to a lack of long, sequential story arcs compared to contemporary hits like One Piece or Bleach. However, the series maintains a dedicated following, with over 9 million manga copies in circulation and a 55-episode anime produced by Studio Pierrot.
The most profound testament to Ninku's legacy lies in its influence on Masashi Kishimoto. While studying to become an artist, Kishimoto copied Kiriyama's drawings and cited Ninku as his primary inspiration. He explicitly stated that his desire to see the Ninku story continue was the driving force behind the creation of Naruto. This connection is further cemented by a 2026 announcement for a four-episode crossover anime between the two franchises, bridging the gap between the original inspiration and its modern successor.
