Ayumu is the "den mother" of the Shinsengumi, Ayumu is the cook and housekeeper at the Shinsengumi compound. A pretty woman with a motherly nature, Ayumu is fully cognizant of what the people around her do for a living, and acts as a sort of big-sister figure to Tetsu.  She is Susumu's older sister, and, like him, a shinobi.

Although traumatized by witnessing the murder of his parents by one of the Choushuu, Ichimura Tetsunosuke's thirst for revenge lead him to desire strength. At the age of 15, Tetsunosuke approached the Shinsengumi, wanting to become one of its members. However, Tetsunosuke lacked the skill, mind and will to emotionlessly cut down whoever threatened peace and the Shinsengumi. Even with the support of his brother Tatsunosuke and his newfound friends of the Shinsengumi, little did Tetsunosuke know the blood and pain he would have to face being part of this historical group.

When childhood innocence gives way to a blinding thirst for revenge, is it worth the price of one's humanity? Tetsunosuke and Tatsunosuke are the sons of a diplomat who sought to bring peace and prosperity to Japan during the early Meiji Restoration. But when their parents are murdered before their very eyes, Tetsu seeks to join the Shinsengumi, the unofficial police who are capable of the same brutality as his parents' murderers. Wading through a sea of espionage, deception and bloodshed, the young boy must choose: should he take a step on the path to becoming a demon...or give up his rage and transform into the ultimate Peacemaker?<br><br>
