While fleeing his brother's samurai, Kuro and Benkei stumble upon a house deep in the mountains. The inhabitant is the beautiful and mysterious Kuromitsu . Kuro is enchanted by the solitary woman but she hides a very dark and bloody secret.

Kuro drinks the blood of the immortal Kuromitsu, but while their bloods mix and the power takes effect, he is attacked by an evil enemy and another who Kuro would never expect.

Kuro awakes in the forest only to realize the entire world has changed. Upon entering a crumbled city in search of Kuromitsu, he becomes entangled with the rebel Haniwa's movement, thus becoming a target of the Red Imperial Army.

Haunted by visions of a past he can't quite remember, Kuro searches on for his love. Rai brings Kuro to Izana who claims he will reunite the lovers if Kuro joins the rebels against the Red Imperial Army.

The Haniwa bring Kuro to meet the rebel leader, Saniwa. She promises to reunite him with his lost love. The Red Imperial Army is desperate to find more of Kuromitsu's blood to breed a new army of enhanced soldiers.

Arashiyama, the demonic General and his army close in on Haniwa base in search of the Miitsu. Kuro and the Haniwa must stop at nothing to prevent the Red Imperial Army from acquiring the blood.

Kuro, Izana, and the other Haniwa journey to Kagura in search of Kuromitsu. Upon entering the underground dwelling of the residents they are shocked by what they find.

In the forest of Kagura, Saniwa has fallen victim to the sorceress Kagetsu. Kuro must battle the vine-wielding sorceress and the winner will be closer to finding Kuromitsu.

Kuro and the remaining Haniwa travel to the fortress of the Red Imperial Army in search of answers, but the road is fraught with death and danger.

Kuro and Rai are captured in the fortress by Hasegawa. The truth of Kuro's dark past is revealed as is the true identity of Kuon.

The truth is near but Kuro must protect Rai and defeat the mutated Hasegawa. Destroying him is only the beginning as he must confront Kuon who is desperate to eliminate any competition for Kuromitsu.

Over 1000 years and Kuro returns to the same hut where his journey began. A battle for life, love, of master and apprentice is the key to the truth. This story has happened before and will happen again... for eternity.
