Psyche is a fashion and lifestyle influencer who actively campaigns for size inclusivity within the rigid social structures of Olympus. As one of Demeter’s daughters, she keenly observes power dynamics but prefers to avoid the political spotlight whenever possible. She is resourceful, fiercely protective of her family, and works hard to maintain her body confidence despite facing prejudice.

Eros is the son of Aphrodite and operates as her primary fixer and enforcer. His violent reputation causes most of Olympus to fear him, socially isolating him and damaging his self-worth. Beneath his dangerous public persona, he deeply resents his mother's control and harbors a desire to experience authentic connection.

Persephone is Psyche's older sister who recently fled the upper city to avoid an arranged marriage to the previous Zeus. Now living in the lower city with Hades, she is deeply suspicious of Eros's motives. She shares a strong bond of trust with her sisters and is always ready to defend them.

Aphrodite is an influential member of the Thirteen and Eros's controlling mother. She holds a bitter rivalry with Demeter and uses her power to enforce strict, conventional beauty standards across Olympus. She is vain, entirely willing to commit murder to maintain her social standing, and treats her son as a weapon.

Demeter is a powerful member of the Thirteen responsible for the city-state's agricultural sector. She is an intensely ambitious mother who actively tries to arrange political marriages for her daughters to consolidate power. Despite her ruthless maneuvering, she genuinely values her children and provides them with a warm home environment.

Perseus is the newly appointed Zeus, having inherited the hereditary title after his father's death. He is a stern young leader trying to secure his precarious political position among the Thirteen. He views marriage as a strategic necessity rather than a romantic endeavor and demands absolute respect for his title.

Callisto is the eldest Dimitriou sister, known for her ferocious temper and disregard for social norms. She is openly contemptuous of the political elite in Olympus. Underneath her aggressive exterior, she holds a deep loyalty to her siblings and is entirely willing to sacrifice her own peace to protect them.

Helen is Perseus's younger sister and a prominent socialite in Olympus. She uses an extroverted, glamorous persona to survive the dangerous politics of the city. She functions as a rare, loyal friend to Eros and is willing to support him despite the potential political fallout from his actions.

Eurydice is the youngest daughter of Demeter. She is described as gentle and beautiful, having recently survived a political crisis that nearly caused a war between the upper and lower city.

Hades is a fallen Olympian leader who rules over the lower city. He provides sanctuary and support to his wife, Persephone, and acts as an imposing political ally for the Dimitriou family.

Eris is one of the Kasios siblings. She uses feigned intoxication to help Psyche escape an uncomfortable matchmaking situation, demonstrating her quiet awareness of Olympus's social currents.

Hermes is Olympus's messenger and a discreet intermediary for the elite. She maintains strict neutrality and confidentiality when delivering sensitive communications between adversaries.

Orpheus is the brother of Apollo and Eurydice's ex-boyfriend. His past actions endangered Eurydice, making him deeply unpopular with the Dimitriou sisters and their protective allies.

Juliette is a size-inclusive fashion designer living in the lower city. She left the upper city due to Aphrodite's influence but continues to create designs that Psyche champions on social media.
