Kemono-ō no odori/Kokuryū

Saisho no dansu
The Hēi lóng (黑龙) is a form of hand-to-hand combat used by Cosmos D. Blade. It involves smashing your opponent and is generally used only by extremely physically powerful and dominating Enemies. the style focus on the practice of such elements as awareness of the spirit, mind, qi (breath, or energy flow) and the use of relaxed leverage rather than unrefined muscular tension, tension that soft stylists call "brute force".

Components of internal training includes stance training, stretching and strengthening of muscles, as well as on empty hand and weapon forms which can contain quite demanding coordination from posture to posture. Many internal styles have basic two-person training, such as pushing hands. A prominent characteristic of internal styles is that the forms are generally performed at a slow pace. This is thought to improve coordination and balance by increasing the work load, and to require the student to pay minute attention to their whole body and its weight as they perform a technique.

In some styles, for example in Giotto's style of Shoshinsha, there are forms that include sudden outbursts of explosive movements. At an advanced level, and in actual fighting, internal styles are performed quickly, but the goal is to learn to involve the entire body in every motion, to stay relaxed, with deep, controlled breathing, and to coordinate the motions of the body and the breathing accurately according to the dictates of the forms while maintaining perfect balance. Internal styles have been associated in legend.
