Unshūmusan

Unshūmusan (雲集霧散, "gathering like clouds and vanishing like mist") is often addressed as the most complicated and dangerous style within, and was invented by Yagura during his younger shinobi days, and one of the reasons for his ascension to.

As-of-now, this style is used by the leader of the, Sasaki Yorukura. He teaches it to his students, so the style can continued to be utilized, even ftare his death. Unfortunately, the style is so demanding none of his students has portrayed the ability to utilize it correctly.

Mechanics
The style focuses on great outbursts of speed and power, which are of such power the human body normally cannot achieve them. Thus, in order to use Unshūmusan, "controlled release" of the is required. This consists of the user opening one or more of the Eight Gates for an instant only, immediately closing them afterwards. This short outburst of power allows the user to go beyond their limits for a second, while overcoming most of the drawbacks related to using the Eight Gates. Students commonly have problems with this, being unable to achieve enough control to close the gates once opened. However, masters like Sasaki can open and close even all of the Eight Gates numerously, allowing for attacks harboring unseen devastation.

Unshūmusan consist of an extensive set of techniques, each one focusing on a different aspect of battle. Although none of these posses a clear numerical order, it's clear that some are on a far higher level than others, and there are several patterns within the techniques. Over the years, the technique became very infamous due it's killing capabilities, resulting in numerous efforts from the other village to copy them, although none of them succeeded in capturing the actual power and precision behind the style. It should be noted that the proficiency of the user is also very important regarding the lethality of the techniques, as a master can do more damage with the most basic of techniques than a novice could ever do, even with the strongest attack of all.

There seem to be two major branches within the style: Togijutsu and Donjutsu. Togijutsu centers about killing or fatally wounding the opponent, while Donjutsu centers around merely knocking out or holding back the opponent without dealing much harm to him. The latter is mostly performed with the flast side of the blade, the guard or the inward curving side. It seems Unshūmusan isn't a style that can be used with any sword, shown when the katana Sasaki picked up from a dead soldier shattered after only one, basic technique.
