Founder of the Kyotouryuu sword style.   ~! He was born in the era of Shikizaki Kiki. Shikizaki Kiki was interested in him. Shikizaki used Kazune to develop the Kyotouryuu sword style, Shikizaki Kiki's 13th complete deviant blade, though because of the nature of the style, it was never perfected. Consequently Kazune developed the style further by passing down each generation, until it reaches Shichika who mastered it.  !~

Yasuri Shichika, seventh successor of the Kyotouryuu (bladeless) sword art, lives on an isolated island with his older sister, Nanami. 
One day Shichika is visited by a woman named Togame, who requests his aid in her quest to find and collect the final twelve swords forged by the legendary master swordsmith, Shikizaki Kiki. Shichika and Togame begin their odyssey by leaving the island he called home for over 20 years. They will face twelve individuals who possess and protect Shikizaki's legendary swords. 
Join Shichika and Togame on an exciting, epic adventure that defies reality as they discover the true potential of the Kyoutoryuu sword style!

A swordless “swordsman” and a self-described “schemer” who embark on a quest to obtain twelve peculiar masterpiece blades. Featuring a gatefold color insert, beautiful interior art, and copious bilingual footnotes, this hardcover edition is the first of a quartet scheduled to collect the entire original run. Brimming with action, romance, and unexpected wisdom, often as tongue-in-cheek as The Princess Bride, and shot through with ninjas, samurais, and secret moves, Sword Tale is Musashi for a new generation and a gift for any fan of adventure.
