Chiaki is the orphaned daughter of the Archangel Michael and a human woman. Ororon is a devil with a bounty on his head. Together, they struggle to stay alive as the battle between devils and the angelic order rage around them.

While Othello and his Blue Dragon Army face down the bounty hunter Mitsume and the Devil Oscar's forces, Oscar himself finds Ororon and his brood. Oscar has been trying to assassinate Ororon this entire time, fearing his younger brother's power and possible desire to ascend to the throne of hell. This time there is no escape and Oscar, insane with hatred and thirsty for pain, proceeds to murder Ororon very slowly, torturing the poor lovesick Chisaki who can only stand by and watch. Chisaki's friends attempt to attack Oscar to allow Chiaki time to escape, but to no avail. They fall at the hand of the powerful devil. But just as Oscar turns his fury to Chiaki herself, Ororon musters all his remaining power to summon a beast to kill Oscar before falling over dead himself before Othello could even arrive with his own army.
