Shōin Shiranui Style

"If you set limits on yourself and what you are capable of accomplishing, then you restrict your soul from maturing... and ultimately stunt any possibility of growth. Realize that there are no limits. The level at which you find yourself presently, you must take a giant leap forward without fear; with clarity of mind. And continue to advance. As you allow your own souls to shine by forging ahead, you serve as a guiding light for those around you. Little by little, that small individual light from you sparks forth the light from several others which do the same for others around them... until the entire world shines brightly. That is the central principle of the Shōin Shiranui Style."

- Seireitou speaking to Minato Kuramoto and Hinata Kusuhana.

Shōin Shiranui Style (松陰不知火流, Shōin Shiranui-ryū; literally "Pine Trees in Darkness Guiding Light Style") is a form of developed by Seireitou Kawahiru and is taught to all students of the Kawahiru Dojang. It is composed from a vast selection of countless martial arts, derived from both the ancient and modern schools, but also features principles and concepts found in the other three disciplines. According to Seireitou, the style's name is meant to symbolize the core tenet of his martial art belief that a martial artist must be the light that guides others out of the darkness; in particular, Shōin is taken from Seireitou's full name.
