Orville is the human form of the Giraffa Undead, the Category King of Diamonds Undead & the last of the Royal Club to appear in the series.
Posing as a human with eye glasses, he is the first Undead to learn the truth about the fake Undead battle & the last Royal Club Undead to be sealed.
He kills Kingston, after using the Riders to fight for him, & steals the Kerberos card to possess the power to seal the Black Joker himself, black-mailing Dirk with the event of their fight tied to the fate of Ada's father to finish the fight.
However, Diamond Warrior intervened & battled the Giraffa Undead on his own, with his Diamond Rouzer having no effect. The Undead was eventually sealed as Diamond Warrior grabbed him & both plunged off the cliff they battled on.
