Olulu, also known as Orle, is a supporting character in Headhunted to Another World: From Salaryman to Big Four!, appearing in both the original manga and the anime adaptation. She is a female ogre from a demihuman tribe, with silver-white hair, three horns on her forehead, and golden-yellow eyes. She is the daughter of the chief of the Ogre tribe, a position that places her close to the leadership of her community from the outset.

Her background is closely tied to the politics of the story's fantasy world. When the Ogre tribe forms an alliance with the Demon King's Army, Olulu joins the army and accepts a position as assistant to Dennosuke Uchimura, a newcomer among the Four Heavenly Kings. In this role, she supports Uchimura in his duties and acts as a bridge between the Demon King's forces and her own people. Her cooperation with Uchimura is aimed at reforming the Ogre tribe, which indicates that her motivations center on the welfare of her family and her community rather than on personal advancement.

Olulu is depicted as kind-hearted and family-oriented. She maintains strong attachments to her father and her tribe, and her willingness to work alongside the Demon King's Army reflects a desire to secure a better situation for those she cares about. Her development follows her transition from a chieftain's daughter into an active member of the Demon King's organization; through her work with Uchimura, she gains experience beyond the boundaries of her tribe and takes on meaningful responsibility within the army.

In terms of abilities, she is not portrayed primarily as a combatant. Her importance lies in her supportive role, her loyalty, and her value as a link between the Ogre tribe and the Demon King's Army, making her a dependable figure within Uchimura's circle.
