Shōka Sonjuku

Shōka Sonjuku (松下村塾, literally meaning "Private Academy under the Pine Trees") is a small private school operated by Shōin Yoshida located in the far outskirts of the Land of Fire.

Overview
Founded for the purpose of providing residence to orphans following the Fourth Shinobi World War while also teaching them academics and how to defend themselves through combat, Shōka Sonjuku was founded by a criminal overlord known distinctively as the Devil King of the Sixth Heaven. In order to essentially hide himself in plain sight, he operates under the alias, "Shōin Yoshida", an innocent and educated schoolteacher. However, while this is meant to serve as a cover, the true purpose in running this school is to slowly drive these children toward the purpose of serving as "instruments of the Sengoku Rebirth".

Trivia

 * The name of this school is derived from an academy of the same name that was run by the real life Shōin Yoshida, a distinguished intellectual from the end of the Edo period. He taught the historical Shinsaku Takasugi and the first Prime Minister of Japan, Itō Hirobumi.
