Ninja Nonsense: The Legend of Shinobu, also known as 2×2 = Shinobuden, is a Japanese manga series written and illustrated by Ryoichi Koga. The series subtitle is "The Nonsense Kunoichi Fiction". The manga was serialized in MediaWorks' Dengeki Daioh magazine between August 2000 and March 2006; the chapters were later compiled into four tankōbon volumes. The manga was released in English in North America by Infinity Studios under the title Ninin Ga Shinobuden. A 12-episode anime adaptation produced by Ufotable aired in Japan between July and September 2004. The anime has been released in North America by The Right Stuf International under the title Ninja Nonsense: The Legend of Shinobu. A sequel manga titled Ninin ga Shinobuden Plus began serialization on Kadokawa Corporation's Comic Newtype website in June 2020. Ninja Nonsense is an absurdist comedy series which follows Shinobu as she trains to become a ninja. However, the series does not only focus on ninja training, but also focuses on Shinobu's lifestyle and friends through a series of disjointed comedic plot lines. The series uses character designs that favor a soft and rounded look rather than the slender bishōjo style. The original title of the series is based on a pun. In the Japanese numerical system, ni is two, and shi is four. Ni × ni = shi, therefore Ni-ni-n ga Shi-nobuden.
Plot
Ninja Nonsense is an absurdist comedy centering on Shinobu, a ninja apprentice, who is attempting to pass her ninja exams while Kaede, a normal schoolgirl, studies for her school exams. As a part of her exam, Shinobu is ordered to break into Kaede's room to steal her panties by her instructor, Onsokumaru. Shinobu, who despite her enthusiasm, possesses little if any actual ninja skills, believes herself to be invisible and 'sneaks' into Kaede's room. Since Shinobu is perfectly visible to Kaede, the mission does not go as planned. Despite all of this, Kaede takes pity on Shinobu and the two become close friends. Shinobu trains alongside other male ninjas identical in appearance, though one is known as Sasuke.

Reception
The anime series of Ninja Nonsense has received generally favorable reviews since its release by Right Stuf Inc. in North America. Positive reception has been given regarding its gag style comedy, the animation, and the cast of characters. T.H.E.M Anime rated the anime 4 out of 5 stars, saying that "Ninja Nonsense is hardly highbrow stuff, but it's clever enough to be amusing and just up the alley of those who want a good gag-laden comedy." Carl Kimlinger, from Anime News Network, praised the anime for its varied animation styles as well as its quality, stating that, "The only constants are that, no matter what style of animation used, no matter how distorted or wild the art, it is always appropriate to the joke or mood of the moment." Furthermore, Kimlinger also credited the characters for their dynamic nature, however advised that marathoning the series can be difficult due to its pacing. In his review on The Fandom Post, Chris Beveridge credited the series for the twists it made to its episodic plots that would be cliche in its "slice of life" genre, highlighting funny moments from certain episodes, including the final episode, calling it "...a very satisfying close." Paul Jensen wrote that the show had a "narrow focus on absurd screwball humor, but did it very well" in his review for Anime News Network. Jensen also called the English dub noteworthy and praised Sean Schemmel's take on Onsokumaru.
