Set during the Edo period of Japan, Kamiwaza tells the tale of Ebizo, an amateur thief who aspires to steal from the rich and give to the poor. On the seedy streets of Mikado, only the tough survive. For one man, a heist gone wrong would change his life forever. During Ebizo's first job, he and his mentor Ainosuke witness the other members of their crew, the Silver Ravens, murdering innocent civilians. Ainosuke then tells Ebizo to flee with the sole survivor of the incident, a child named Suzuna.
