Bakumatsu Kikansetsu Irohanihoheto (幕末機関説 いろはにほへと, Bakumatsu Kikansetsu Irohanihoheto) is a Japanese anime series, created by Ryōsuke Takahashi and Sunrise. It premiered October 6, 2006 on the Japanese internet streaming channel, GyaO.

The Shogunate is in its final years, and war is fast approaching. When Akizuki Yojiro, a dark and mysterious mercenary, nears something supernatural with some kind of importance to him, the ornament on the end of his sword hilt waves in its direction, his eyes glow mysteriously, and he is driven to go after it.

He comes across a traveling theater group who is out for revenge for killing the parents of the group's leader, and whose mysterious playwright likes to secretly help along events of history.

Yojiro joins them to lend them his skill against their enemies, while dark conspiracy continues to follow behind him.


The end of the Edo era marked the last time men would live as samurai and fight entrusting their lives and beliefs to the sword. The peace of the Tokugawa Shogunate begins to crumble with the arrival of Western influence.

Amidst this upheaval, the youth of the nation seek a new era, but something else will bring turmoil and chaos. It is called Hasha no Kubi; the Head of the Conqueror. It is said that he who can obtain the Head shall rule over the whole country.

However, another shadow being called “Eternal Assassin” is destined to oppose Hasha no Kubi. These two beings have been in eternal conflict, affecting the course of history from the shadows, influencing those who craved power. Some want it for their own, some want it for revenge, and some want it to fulfill their own ideal.

The wills of men intersect over the Hasha no Kubi. They combine and move together like complicated gear wheels of an engine pushing events towards the future.
