To the far east, there lies a small island nation known as Yamato. Once peaceful, it is now engulfed in bloody conflict.

The ruling shogunate is served by Hozuki, a team of enforcers who maintain order and purge the shogunate’s enemies.

Day and night, they fight against Byakuya, an organization seeking to overthrow the shogunate.

Some strive to maintain order, and some strive to bring about a new era. Those known as samurai risk it all to realize their ideals.

Mukuro, a member of Hozuki, must decide whether she remains loyal to the shogunate or harbors doubts that lead her to join Byakuya. Or she may choose to trust no one and forge her own path as a ronin, beholden only to herself.
