Eros fulfills the divine role of the God of Love. He is Pollon's cousin and closest companion, wielding heart-tipped arrows to incite romantic feelings in others as part of his duties. Ironically, Eros himself possesses notably unattractive features, leaving him without a romantic partner.

His background is deeply shaped by family. Aphrodite, the Goddess of Beauty and his mother, exhibits vanity and preoccupation with her own appearance. This contrasts sharply with Eros's traits, leading her to express shame over his unattractiveness and occasionally disown him.

Eros displays a playful and mischievous nature. He frequently causes humorous disruptions by impulsively using his arrows, prioritizing immediate experiences over long-term planning. Despite this, he demonstrates loyalty and dependability when aiding friends facing difficulties.

His relationship with Pollon remains central. Eros consistently participates in her endeavors, often becoming entangled in the resulting complications. Their interactions involve shared comedic misadventures impacting both divine and human realms. He provides companionship during her quest for godhood, though his methods sometimes unintentionally worsen situations.

Within the broader narrative, Eros appears in a scene of the related work "Nanako SOS," depicted as part of a television show playing within that series. He functions primarily as a supporting figure within the comedic structure, with his attributes and relationships remaining consistent across all appearances.
