Highlights
The Rasenshuriken, despite its frequent usage by Naruto, is classified as a forbidden technique due to the threat it poses, including self-harm and destructive capabilities.
Forbidden techniques are classified according to factors such as self-infliction, immorality, infringement of natural laws, and potential for extensive devastation.
While Naruto employs forbidden techniques like the Rasenshuriken, there exist no rigid regulations or repercussions governing their utilization, and he has discovered methods to minimize the detrimental effects they inflict.
The Naruto series features numerous unexplainable abilities and overpowering techniques, but only a select few are considered forbidden. The shinobi world has strict criteria for labeling a jutsu as forbidden, making it surprising to see some relatively common jutsu falling into this category. Among them is Naruto's iconic Rasenshuriken, which is designated as a Kinjutsu (a term reserved for forbidden techniques).
Despite Naruto's frequent utilization of the Rasenshuriken, the Hidden Leaf Village still classifies it as a Kinjutsu. This classification may seem peculiar, considering Naruto's frequent use of the technique in battles, almost surpassing the Rasengan in his arsenal. However, upon closer examination of the intricate mechanics behind the Rasenshuriken, the accompanying threat becomes evident, making the decision to deem it a Kinjutsu entirely logical.
How Are Techniques Classified as Forbidden?
Before delving into the intricacies of the Rasenshuriken's lethal workings, it is important to understand how techniques are deemed forbidden. One key factor is the presence of self-harm, as it can lead to a technique being classified as Kinjutsu. Guy Sensei's Eight Inner Gates, for instance, are forbidden due to the irreversible damage they can cause to the user, even resulting in death. Another category includes jutsu involving self-sacrifice, such as the Uzumaki Clan's Reaper Death Seal.
Techniques that are considered immoral and violate the laws of nature are also prohibited from use or instruction. Orochimaru's Edo Tensei, for example, was banned because it manipulates the souls of the deceased and disrespects the dead. Furthermore, techniques capable of causing widespread destruction are banned to prevent indiscriminate harm to both allies and enemies.
The Rasenshuriken's Complex Workings
The Rasenshuriken, which is the evolved form of the Rasengan, operates on the same foundational principles but on a much larger scale. Initially, Naruto's clones were required to create the Rasenshuriken - one clone contained the chakra while the other added Wind Release to the spinning chakra ball. True to its name, the Rasenshuriken takes on a shape similar to a Fuma shuriken, with four sharp edges surrounding the central base. However, these four blades are not merely ornamental; they possess remarkable sharpness and the ability to easily cut through solid rock.
Upon impact with its target, the Rasenshuriken causes the chakra ball at its core to explode, generating a wind vortex infused with countless minuscule wind blades. These wind blades are incredibly sharp, capable of penetrating through an individual's cells and even disrupting their chakra network. The resulting damage from the blast of wind blades can be so extensive that a direct collision can permanently render the victim unable to perform jutsu.
Why Is Rasenshuriken a Forbidden Technique?
The Rasenshuriken is classified as a forbidden jutsu due to the risks it poses for both the caster and the victim. Initially, Naruto couldn't maintain its form after throwing it and had to resort to using it as a melee technique, which caused minimal but reversible cellular damage to his own arm. However, continuous usage would have resulted in permanent damage, making it a dangerous technique. Because it causes self-harm to the caster, Lady Tsunade deemed it a Kinjutsu.
Although Naruto found some workarounds by infusing Sage Mode chakra into the ability, there are still other factors that make it a threat. The Rasenshuriken's destructive nature is one such deadly aspect, leaving anyone caught in its wake severely incapacitated and unable to mold chakra. This poses a risk for allies to get caught within its radius, particularly since Naruto uses it as a projectile technique. Furthermore, one can argue that the technique is immoral as it completely strips the victim of their Ninjutsu abilities.
Naruto’s Usage of Forbidden Techniques
Naruto frequently uses forbidden techniques like the Rasenshuriken and Multi-Shadow Clone Jutsu in Shippuden, despite their prohibited status. This raises the question of why these forbidden jutsu are utilized so often without consequences. It appears that there are no strict rules governing the usage of forbidden techniques, and there seems to be a lack of punishment for those who use them. Despite this, Naruto has managed to find ways to use these techniques safely and protect himself and others from their potential harm.
Naruto is now available to stream on Crunchyroll.
