Ito Ittosai Kagehisa

Around the conclusion of the Sengoku era in 16th-century Japan, Ito Ittosai Kagehisa was born. Even while we don't know all the specifics of his early years, we do know that the abilities and strategies he honed over the course of his life make him one of history's greatest swordsmen. Itto-ryu, commonly known as the "One Sword" style, is the combat method he invented and is still regarded as one of the most important schools of Japanese swordsmanship because it gave rise to many other fighting methods still practiced today.

Kagehisa spent a lot of his life traveling and competing against other expert swordsmen, just like many other skilled swordsmen of the time. Along the process, he picked up a number of fighting techniques, finally creating his own own fighting school. Itto-ryu finally became so well-liked that the Tokugawa shogunate selected it as one of the two official combat schools.
