幕末機関説 いろはにほへと• Bakumatsu Kikansetsu Irohanihoheto
Synopsis & Story
In the final years of the Bakumatsu, wandering mercenary Yojiro Akizuki travels the length and breadth of Japan. And while he employs his sword in the usual fashion, he also uses it to help him locate supernatural items which he pursues with single-minded determination, often with bloody results. In the course of his quest, he crosses paths with a traveling theater group whose members have their own dark agenda. Is it a chance meeting or the result of some, as yet, undiscovered conspiracy?
