Shadow Warriors

When a five-year old boy, Ietsuna, suddenly becomes the Shogun of Japan, numerous schemes to seize his power begin to hatch. The Shogun's trusted guardian, Hoshina, secretly asks the leader of the exiled Iga ninja clan, Hattori Hanzo, to help protect the stability of the nation.

Under orders from the Kouga clan, a revenge-seeking female ninja, Okou, infiltrates the bathhouse that doubles as the Shadow Warrior's secret base. Meanwhile, a wild Iga ninja causes trouble for Hanzo by refusing to remain in hiding.

A minor clan comes to Edo looking for warriors to help them take over a castle. Hanzo is suspicious that dirty politics are involved, but is convinced by Okou to help lend his arm in battle despite the hopeless odds.

After several loyal courts nobles are brutally murdered, Hoshima suspects a plot against the goverment is brewing in Kyoto. The Shadow Warriors leave Edo to try and stop the conspirators. But will Okou's desire for revenge ruin everything?

Under the guidance of a ninja hunter, the Tokushima clan is secretly gathering weapons and plotting a rebellion against the government. A bloody civil war will break out unless the Shadow Warriors can sneak into enemy territory and disrupt the plot.

The Iga ninja of Nagasaki are accused of running an illegal opium ring to help fund a campaign against the government. Hanzo and the Shadow Warriors venture to Nagasaki's foreign quarter to try and prove their clan's innocence.
