Wuxuang Quanwu (武双圏舞 Wǔshuāng Quānwǔ?, Literally meaning "Paired Martial Arts' Sphere Dance") is an incredibly complex Fighting Style that takes elements from classical Martial Arts and combines them with Busoshoku and Kenbunshoku Haki for the ability to procure an instantaneous and, if mastered completely, almost sentient defense. The only living practitioner of this art is Xiao Feng, at least, from the original Kingdom of Hundun. It was due to this particular Fighting Style that the Marines were afraid of Hundun's residents turning against the World Government, hence the Buster Call initiated on the island. Users of this fighting style are known as Zhiwuren (志舞人 Zhìwǔrén?, Literally meaning "Dancer of Willpower").
Wushuang Quanwu, at its basis, is the condensation of one's Kenbunshoku Haki range, leaving it to surround the individual at a close proximity to oneself: about one meter. In order to minimize the range of one's Kenbunshoku Haki, the individual must take upon a stance of their choosing to gather the required focus to do so. Often times, it appears that the stance is defensive in nature, with arms spread a distance apart and with open palms. However, true masters of the technique can use the fighting style upon reflex, having trained their mind, body and soul (in terms of willpower) to the point where this technique is nothing more than an expression of their internal self. The style may also be used with weaponry, rather than solely being a product of unarmed combat. The overall process of reducing the range of one's Kenbunshoku Haki is akin to the manner in which people focus Busoshoku Haki close to themselves, albeit applying it to their sensory perception instead. When achieving this particular stage, the Wushuang Quanwu's basic attributes can be accessed by an individual.
The Wushuang Quanwu's basic attributes primarily consist of almost instantaneous reflexes. Through a combination of one's Kenbunshoku Haki providing precognitive abilities and an individual's physical prowess, the user can effortlessly bat off almost all attacks that come towards their being. This is particularly useful as both a defensive and an offensive technique, as it enables a user to determine how far the next attack is and appropriately adjust their own timing and style to be either more offensive or more defensive. More often than not, Wushuang Quanwu, in the hands of an offensive fighter, can quickly enable critical blows to be dealt within battle, bringing down the user's opponents in nothing more than one or two strikes.
However, as noted by Xiao Feng, the style's potency is only as good as the user's skill. Moreover, there are actually a few ways to break through the original technique. Any Martial Artist of sufficient caliber can potentially make use of the weakness of the legs being stationary to their advantage. However, to an individual who has mastered the likes of Kami-e, their legs are nothing more than another medium to express a Wushuang Quanwu sphere. Moreover, combination attacks from one or more individuals at one time of sufficient speed and strength can quickly break through the foundation of the technique, given that it requires one to normally be stationary. Finally, a continuous series of shifts in an opponent's fighting style would ultimately overcome the protection provided by the sphere, given that it requires one's Kenbunshoku Haki to be able to consistently read an opponent.
Wushuang Quanwu: Huanliu (武双圏舞・环流 Wǔshuāng Quānwǔ: Huánliú?, Literally meaning "Paired Martial Arts' Sphere Dance: Surrounding Flow): A highly advanced application of the original technique. Rather than keep one's Kenbunshoku at a small range from oneself, the user compresses it inwardly even further, to the point where the only thing that can be sensed with the said Haki variant is motions that are only five centimeters away from him, at best. The end result of this, however, is an extremely refined reflex, to the point where any ordinary attacks and, indeed, combination attacks prove almost completely ineffective given that the individual can also move around freely. Of course, this requires an extreme amount of focus, which no ordinary combatant can attain. This particular skill, when combined with an individual who possesses an extremely high physical fitness, can be used for a wide variety of purposes. Counterattacks can be performed with the utmost ease, and even attacking first doesn't come at any detrimental cost, given that the user can exploit any immediate opening with flawless precision and accuracy. When employed by a master of Xiao Feng's caliber, the user can even catch attacks enhanced by the extreme speeds of Soru and Shigan's caliber by forcing the user to their physical limits, thus causing them to employ techniques of similar speed and precision.
Wuxuang Quanwu — Yishan (武双圏舞・一閃 Wǔshuāng Quānwǔ — Yīshǎn?, Literally meaning "Paired Martial Arts' Sphere Dance — Brandish): A technique actually devised by Xiao Feng's mother. The Wushuang Quanwu's one weakness besides its ability to be broken by combinations and similar techniques, is the fact that its activation is very slow and, often, harmless. Xiao Feng's mother, a master of the Wushuan Quanwu, managed to circumvent this weakness through her peculiarly calm personality as well as her mastery over Haki. When condensing one's Kenbunshoku Haki to the desired range, one simultaneously releases their Busoshoku Haki in a spherical formation around themselves. This immediately repels any weaker combatants with great ease, while giving the user the necessary preparation to temper their Wushuang Quanwu for the assaults that will strike the practitioner straight afterward. Xiao Feng obtained this technique from his mother prior to his departure from the Hundun Kingdom, just before the entire Kingdom was massacred.
Wuxuang Quanwu — Shihao (武双圏舞・十号 Wǔshuāng Quānwǔ — Shíhào?, Literally meaning "Paired Martial Arts' Sphere Dance — Buddha's Ten Epithets): A technique created by Xiao Feng's master, Xuan Wu, prior to him passing away. The Wushuang Quanwu's primary weakness, as exploited by several individuals, is that it can be broken by combination attacks. This is due to the physical limitations of the individual within the sphere erected by the Wushuang Quanwu which is evidently too narrow to accommodate for more than two people to fight in at a single time (the user of the sphere and their opponent). While the most evident solution is to increase the range of the Wushuang Quanwu sphere this, obviously, is not exactly favorable given that it reduces one's chance to immediately counterattack. Even more prevalent, the shift in one's attack pattern within the sphere would quickly cause the individual to be overwhelmed. As compensation, one may apply extreme speed and composure to create a rather large number of afterimages to counteract up to ten individuals (or more depending on the user's skill) at a time. Each afterimage, given that the user is constantly moving in response to any attack, temporarily feigns a physical mass by way of the user's Busoshoku Haki, making only the most coordinated of efforts a plausible means to break through this formation. Xiao Feng, given his level of skill, can employ this technique with his Shugami as an alternative. However, he often makes use of it as a homage to his master. That being said, he can alternate between both — or even use them simultaneously — for an exceptional outcome.
Wushuang Quanwu: Huanliu — Shoushen (武双圏舞・周流・手神 Wǔshuāng Quānwǔ: Huánliú — Shǒushén?, Literally meaning "Paired Martial Arts' Sphere Dance: Surrounding Flow — God Hand): A technique that has become Xiao Feng's most significant achievement within the Wushuang Quanwu form. Xiao Feng's innate talent, extraordinarily potent Haki, great willpower and emotional control enables him to, ideally, manifest his Haki in the form of ethereal constructs. They are most often elongated arms due to their practicality. Through employing this skill as an unconscious extension of his Shuryu form, Xiao Feng is capable of using his Busoshoku Haki for an extra layer of defense, especially to react to his blind spots. These arms, given that they're made of Haki, can also bypass most Devil Fruit abilities with ease. However, the most useful application of these arms, when used in conjunction with Shuryu, is that the arms act as "sentient" extensions capable of reacting to any threat perceived by the hyper-condensation of Xiao Feng's Kenbunshoku Haki, to the point where it is virtually impossible to bypass their reach. Of course, this is wholly dependent on how quickly Xiao Feng's Kenbunshoku Haki can perceive a given threat which, in general, is generally extremely fast.
Wushuang Quanwu: Kodume (武双圏舞・虎爪 Wǔshuāng Quānwǔ: Kodume?, Literally maning "Paired Martial Arts' Sphere Dance: Tiger Claw"): Kaizen, being an offensive fighter by nature, found the defensive form of Wushuang Quanwu rather restricting. While it had its many uses, Kaizen ultimately believed that any fighter should live by their own form, rather than the form that others impose upon them. Accordingly, he spent a considerable amount of time with Xiao Feng modifying the base nature of Wushuang Quanwu to suit his needs. Eventually, he would arrive at the conclusion of Kodume. Kodume, unlike Wushuang Quanwu's traditional approach, instead focuses his Kenbunshoku almost completely around his limbs. Should the practitioner be wielding a weapon, they can flow it across that medium as well. In doing so, that specific medium for attacking transfers all the possible outcomes that it faces as it goes to strike an enemy to the user's mind. In accordance to these visions, the user is capable of — with great physical maneuverability — shifting the direction and nature of their attacks at the very last second, thus completely overwhelming an average opponent's reaction time and enabling critical blows to be landed successively without expending senseless amounts of energy. Notably, by covering the medium(s) with both Busoshoku and Kenbunshoku Haki simultaneously — while halving their individual potential — one can adequately fight against conventional Devil Fruit users with ease, albeit those with particularly advanced abilities cause this split between sensory and offensive power to be rendered ineffective.
- Wushuang Quanwu's overall concept was greatly inspired by Seikuken and Ryusui Seikuken from History's Strongest Disciple Kenichi.
