Ryūken Academy

Ryūken Academy was an orphanage/ninja school based in the Land of Fire. It was founded by Daisuke Ryūken after the Third Shinobi World War with the intent of finding and helping lost children throughout the entire shinobi world. Even after his Daisuke's death, the academy prospered for a few years until a horrific tragedy resulted in all of the students' and teachers' deaths, with Kazuto Ryūken being the only survivor.
