Tatsumi is a self-acknowledged country bumpkin who is nonetheless a well trained fighter. He and two companions leave their remote village to head to the Imperial City to find a way to relieve their friends and family from ruinous taxation imposed by the authorities. Yet the Imperial City is filled with unimaginable amounts of corruption and evil from supernatural sources. Tatsumi is immediately swindled after reaching the City and nearly loses everything soon after, but finds himself allied with an unlikely group of assassins. Source: ANN
