Munetaka Yagyuu

Munetaka Yagyuu is a dark and mysterious figure throughout the anime. This older gentleman, with an injured eye and scar, dresses in Western-style clothing, carries a katana, and rides a motorcycle as he disappears from the city.

He works from the shadows, at first using Marie Claire as his servant to observe Tendou Kodzunu's progress in disrupting the Dragon Stream. The black cat that Claire keeps is his familiar.

Yagyuu is in fact the prime antagonist, and his ultimate goal, though vague, is to throw society into chaos and conflict; he seeks a new world order to exalt himself. The first opportunity he uses the revival of the Kodzunu clan, and later turns to manipulating the Martial Fist and locating the Black Dragon, Yin to the Golden Dragon. His past is an enigma, but his evil powers were seen throughout Japan's history. Yagyuu was once sealed away by earlier Stars of Fate, but he broke free and was reborn, and continues his quest for domination.
