The leading man, and a samurai of noble spirit. A master of the Shinkage-ryu fighting style, his main concern is taking over the Yagyu Dojo, as the new Master. The Yagyu family has been teaching the Tokugawa clan swordsmanship for centuries, and Muneakira, or "Mune" for short, aims to keep that traidition strong. Officially under the Tokugawa clan, Mune has just gotten to Buou Academic School (a school where only warrior students can attend, and a breeding ground for Japan's next great leaders) and he's already found himself with a world of problems... and two of them like to follow him around.

Has great skill with a sword, and is a childhood friend of Sen Tokugawa.
