Olympe, daughter of Apollo, resides on Mount Olympus. Her mother remains unidentified, leading to her upbringing by her neglectful father. Apollo's frequent laziness and drunkenness force Olympe to assume his duties, including driving the sun chariot across the sky.

She possesses a persistent desire to achieve godhood, fueled by a fundamentally kind-hearted and optimistic nature. Her attempts to prove herself involve performing good deeds or assisting others, though these actions typically backfire, causing unintended chaos for gods and humans. Despite recurring failures, she maintains an indomitable spirit and refuses to abandon her goal.

Her closest relationship is with her cousin and best friend, Eros. They constantly bicker and exchange insults but remain deeply loyal companions who collaborate on misadventures. Interactions with other deities are often strained: Aphrodite, Eros's mother, displays vanity and dismissiveness toward her; Zeus, her grandfather, occasionally shows grudging affection amid his pursuits; Hera, her grandmother, exhibits volatile reactions to Zeus's infidelities, creating a turbulent familial environment.

Through her experiences, Olympe undergoes gradual maturation. While retaining her inherent mischievousness and penchant for comedic errors, her actions evolve toward genuinely beneficial outcomes. This development culminates in her achieving divine status as the "Goddess of Hope," signifying her earned role as a symbol of perseverance and optimism.

Beyond her core narrative, Olympe makes a brief, non-speaking cameo within a television scene in the unrelated series "Nanako SOS."
