Shunkō is the highest form of Hakuda technique. It comes in elements such as 'wind' or 'lightning'.[4] It is an ultra-powerful technique in which one drives Kidō into one's arms and legs.[5] The Kidō itself can be controlled and fired at opponents from the body.[6] Shunkō was first used by Captain Suì-Fēng in her fight against her old master, Yoruichi Shihōin. Suì-Fēng states she invented the technique of combining Kidō and Hakuda so recently she had no experience with it in battle, let alone enough time to give it a name. Yoruichi, however, reveals Shunkō is the technique's name, and she invented and learned the ability long before Suì-Fēng. The keisen uniform has no back or sleeves because the fabric will rip apart when the user's back and arms are filled with Kidō. Though Yoruichi's Shunkō is perfected, she still has difficulties controlling it. The uniform worn when punishment is carried out is specifically geared for Shunkō.[5] By concentrating Shunkō around a particular area of their body, a practitioner can prevent attacks from damaging or piercing this area.[7]

uì-Fēng would go on to complete her version of the technique after her fight with Yoruichi. She discovered a technique for making the Reiatsu she emits revolve around her like a vortex indefinitely, allowing her to maintain her Shunkō for as long as she wishes once she activates it

he pressurized Kidō emitted from Yūshirō's back creates a large explosion of concentrated energy, which engulfs his opponent and heavily damages them.[13] Shunkō: Bakuen Musō (瞬閧 爆炎無双, Flash War Cry: Exploding Flames Unparalleled; Viz "Unrivaled Explosive Flame")
The tailed beast's chakra performs the Lightning Cloak, while my chakra works as natural force field.

Version 1 – or what Jiraiya calls Naruto's "demon fox cloak" (妖狐の衣, yōko no koromo)[1] – forms a dense shroud of chakra around the jinchūriki. The shroud, a translucent red with bubbles of chakra (reminiscent of boiling liquid) forming all along it, provides a degree of physical protection, but can also harm the user if used to a certain extent. The physical changes experienced in the initial transformation become more pronounced in Version 1 forms.
The shroud that encompasses the jinchūriki vaguely resembles the corresponding tailed beast; paws of chakra form around their hands and, in the case of Killer B, chakra-horns form on his head. Because chakra is malleable, the shroud can extend beyond the reach of the jinchūriki, often used to create chakra-arms that allow them to interact with their environment. The most significant manifestation are the tails that sprout from the jinchūriki's body, up to the maximum number of tails that the corresponding beast possesses. As with the chakra-arms, these tails can aid the jinchūriki by grasping to their surroundings. For each tail produced, the jinchūriki gains an incrementally greater boost to speed, strength, and chakra.
The source of the chakra shroud differs between users. For jinchūriki who have not learned how to control their tailed beast, it is the beast's chakra that surrounds them. The beast's chakra will tend to be harmful: individuals near the jinchūriki will experience a slight physical discomfort; those who come into contact with the shroud will suffer a painful burn wherever they touch it; the jinchūriki themselves suffer an increasing amount of corrosion to their body that can eventually damage body parts beyond the point of use.[2] This shroud is typically acquired through a growing rage and/or the weakening of the seal that keeps the beast within their body, and consequently leaves the jinchūriki less in control of their body with each additional tail. While a jinchūriki has never been observed to completely lose control of themselves in a Version 1 form, they become more animalistic and aggressive. One advantage of this is that the shroud can act on its own, responding to threats the jinchūriki may not be aware of.
The user wraps their body in a layer of lightning chakra to increase their physical parameters, with more lightning causing greater increases. As users coat more lightning chakra around themselves, the more their hair sticks up.[2] The lightning augments the strength of the user's taijutsu, creating what is called nintaijutsu.[3] The lightning also defends the user from most attacks, deflecting them away on contact;[4] the Fourth Raikage is impressed when Chidori pierces through to him, however slightly.[5]
The lightning chakra stimulates the user's nervous system, enhancing their speed and their reaction time.[6] The user's reflexes are heightened enough to perform a Lightning Release Body Flicker (雷遁の瞬身, Raiton no Shunshin, English TV: Lightning Style: Teleportation), dodging attacks as fast as Amaterasu.[7] The user is so fast that not even the Sharingan can track their movements;[6] only Minato Namikaze's Flying Thunder God Technique and Naruto Uzumaki's Nine-Tails Chakra Mode have been shown to be faster
Taking advantage of the innate properties of Wood Release which allows the user to force trees to grow on any surface at a rapid pace, the user creates a dense forest of flowering trees. During the forest's formation, the user can have the branch restrain any target(s) that tries to attack the user before the formation of the forest is complete. The pollen produced by these flowers is then released into the atmosphere and when inhaled, renders any afflicted target unconscious. The user can also control where the pollen spreads so it does not affect them nor their comrades. The pollen is also capable of penetrating Susanoo's defences.
With enough willpower, it is possible to regain consciousness, however, in order to counter the technique fully, either the trees themselves must be destroyed completely or the target must continue to remain elevated above the dispersed pollen
