In 1960s Japan, a low-ranking samurai by the name of Sakamoto Ryoma is disappointed with the longstanding shogunate reign. Foreign guns have arrived on Japanese shores, widespread poverty plagues the common folk, and the era is ripe for a revolution. After Ryoma’s adoptive father is assassinated for leading a revolutionary group, Ryoma vows vengeance, seeking nothing less than to bring an end to the samurai era. In a twist of fate, Ryoma sets out to bring down the shogunate by infiltrating it from within. He joins the Shinsengumi, an elite force of samurai warriors, to hunt down his father’s murderer. But Ryoma is not the only one with an agenda, and he is drawn further into the operations of shogunate rule the more he pursues his cause.
