In the year 1580, a man named Lord Nobunaga Oda sends hoards of unholy armies across Japan, slaying all who stand in their way. A young ninja escapes her villages' destruction with a short sword, one of the three mystical weapons that can end Oda's rule. During her quest, she is joined by two other ninjas who wield the other two weapons of legend, the sacred sword and spear.

The story centers around Saburou, a high school boy who time-travels to Japan's Sengoku Era. He must become Nobunaga Oda, the famed warlord who helps unite Japan.

The year is 1580. Using an army of soldiers equipped with sophisticated weaponry, Nobunaga Oda is on the verge of ruling Japan with an iron fist. One of his enforcers is Ginnai Doma - a fallen samurai reborn into an indestructible killing machine. As Ginnai continues his killing spree on ninjas and those who oppose Nobunaga's rule, Shishimaru of the Iga Ninja - going against the Koga Ninja's plans - pursues a one-man vendetta to avenge the deaths of his comrades and kill the immortal warrior.

The ninja banish evil from the shadows. The gokudo gather lonely outcasts and commit crimes. The grudge they forged centuries ago is rekindled in the present day. The ninja Shinoha meets Kiwami, a gokudo with the face of a businessman. Unknowing of the other's identity, they bond over anime, but the war between ninja and gokudo intensifies. Who will survive and who will perish, ninja or gokudo?
