Shintai Sonjuku

"Everyone... After this, you will be forced to shoulder great responsibility. If you merely continue walking, you will find many things barring your way. What you do when that happens, is entirely up to you. I will not be able to guide you forever. So for now, I offer you these words. Fearing others, and picking up your sword to protect only yourself... Leave such thoughts behind. Wield your sword, not to defeat your opponents, but to protect your very soul."

- Shōyō's teachings.

Shakyaryū Dojang (샤카류학교 (釈迦竜と学校), Shakyaryuu Dojang) was an institute founded by Shōyō Shakyamuni. It remained as the last of several schools that taught their own principles of combat that were not subdued by Genryūsai Shigekuni Yamamoto during the founding of Shinō Academy and the subsequent wartime events that followed. The school, according to Shōyō, stood for the purpose of spreading the teachings of the "soul protector". It was a belief that the power used by a person is meant, not to defeat an opponent nor to protect one's self, not even to cut away one's weaknesses, but to protect one's soul. Subsequently, it is meant to protect one's own soul: their pride, their morals, and their beliefs; to never yield to another's will. But most of all, to protect the fragments of one's soul, passed on to those that one would form bonds of friendship with. It treats the soul as an organ within the body that holds more significance than even one's heart or mind, and that as long as the soul exists, even if the body is crushed to pieces, one can keep fighting.

Having been in Seireitei, Shōyō took in promising young children who would learn about the combative and educational aspects in order to become well-rounded individuals. It was here that the eighth generation of the Yonkō received their teachings and was the first institute to have its students become Captains within the Gotei 13. It was burnt down during the Vandenreich invasion and its teacher subsequently killed in future events by his own student.
