When Chiaki meets a wounded young man on the street and offers to take him in, she has no idea that she's just invited the King of Hell to move in with her.

Ororon has abandoned his throne, causing renegade demons, bounty hunters, and his own brothers to come after him to take his crown.

Their relationship remains strained throughout the series as Ororon attempts to refrain from killing for Chiaki's sake, leaving himself open for attack in the process.

The powers her angelic father sealed within her level an entire city during a battle with several bounty hunters, and Chiaki spends the rest of the series in agony over her hatred of what she and Ororon must do to survive.
