House of Five Leaves

Masterless samurai Akitsu Masanosuke is a skilled and loyal swordsman, but his naïve, diffident nature has more than once caused him to be let go by the lords who employ him. Hungry and desperate, he agrees to become a bodyguard for Yaichi, the charismatic leader of a group calling itself “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.
