愛渊移香
Aisu was originally a pirate based in Kumano, who raided Japanese and Chinese shipping and whose travels took him on occasion as far as the Chinese mainland.After suffering a severe shipwreck off Kyushu, of which he was the only survivor, Aisu abandoned his life as a pirate and entered into seclusion at the Udo caves in Miyazaki Prefecture.
He was inspired to create the new school in 1488 while leading a secluded life in a cave at the Udo Shrine. His style was inherited by the father of Hidetsuna and greatly influenced later the Yagyus, who were distinguished swordsmen in later eras. After travelling throughout Japan on a martial pilgrimage for some years, Aisu returned to Kyushu, where he died of natural causes.
