A many-sided tale of faith and betrayal, drama and intrigue, set in the world of old Edo.

Masterless samurai Akitsu Masanosuke is a skilled and loyal swordsman, but his naïve, diffident nature has time and again caused him to be let go by the lords who have employed him. Hungry and desperate, he becomes a bodyguard for Yaichi, the charismatic leader of a gang called "Five Leaves." Although disturbed by the gang's sinister activities, Masa begins to suspect that Yaichi's motivations are not what they seem. And despite his misgivings, the deeper he's drawn into the world of the Five Leaves, the more he finds himself fascinated by these devious, mysterious outlaws.

Once known as “Sei the Drifter,” Yaichi has maintained a coldhearted outlook on life, a despair rooted in the trauma of a kidnapping that occurred years ago. With his past now coming to light, an air of restlessness pervades the Five Leaves. At the same time, Masanosuke must make a difficult decision when confronted with his brother Bunnosuke’s complicated circumstances.
