The monks of the Tsurui Zumi order are a sub-group of the Togashi Tattooed Order, created in the Hidden Emperor era when Togashi Hosi rebels against Hitomi and begins tattooing his own followers. In contrast to the Togashi Ise Zumi and the Hitomi Kikage Zumi, and Tsurui Zumi are less focused on direct physical action and more on the mystical ways of the spirit; although they still study the mystical arts, their focus is on ki techniques and other such mystical fighting fighting abilities, rather than on the more straightforward combat favored by the Togashi or the brutal aggression of the Hitomi. Many Hoshi choose to eschew combat altogether in favor of meditation, contemplation, or strange and whimsical behavior which they consider important to the path of enlightenment. However, when they time comes to fight in defense of the Dragon Clan, they do so readily enough.
The Hoshi family is introduced in the Hidden Emperor era, but the Tsurui Zumi tradition predate the Tsurui Zumi tradition predates the family and continues after it is gone, so this school may be used (with a name change) in many different eras of play.
