Tento Seiin Ken

Tento Seiin Ken (天斗聖陰拳 Heaven Dipper Sacred Yin Fist) is a martial art appearing in Souten no Ken: Re:Genesis. It is the ancient martial art of the Nahash tribe. It has influences from the Seito Gekken style from when the Nahash met the Yuezhi millennia ago. It's shown to be a vampiric style that sucks away the tōki of its opponents. In the manga it is stated that the original Teito bloodline are called the Dragonians (創天龍人(ドラゴニアン)) and carry a gene called the Dragon God Factor (龍神因子) that allows them to emit light called ruach (רוּחַ).

This style is used by Simeon Nagid, Himka, and Shomer in the anime and Van der Kool in the manga, although Van der Kool is not of the bloodline.
