Thunder's Dagger Dojo taught the Bayushi Bushi and Shosuro Ninja schools. It was the only bushi dojo in the Shosuro lands. It was a Bayushi Bushi school located within Nihai Tower. The existence of the dojo also concealed why many Shosuro Ninja were competent with the use of swords. The school took its name as homage to the first Scorpion Thunder, Shosuro. The school developed a unique technique several generations ago and added it to the Bayushi style of fighting, and the only place where could be learned the Thunder's Dagger kata.
