The secret organization "D" employs the Four Demon Kings and the man-made monster, SX, to massacre numerous innocent people to implant horror and loathing toward demons into people's minds. Seeing the organization's atrocious deeds in the name of God, Sosuke, a member of the organization, becomes skeptical, while Lamia captures Saori and Ryo seeks the help of Saeko.

Although Saeko rescues Saori, Saeko becomes trapped in the labyrinth herself by the Four Demon Kings! Ryo, along with demons, fights to save Saeko, who then brings Ryo back to the past to show him the forgotten history of demons and God. What fate awaits Ryo as his memory returns and his real identity as Demon Lord Dante is rekindled?
