Flore hails from Marmelo, a planet where her father Gyron’s regime systematically persecutes "Minus Psychic" individuals in a campaign to eradicate them. A Minus Psychic herself, she flees to Ceres Station, a Earth-defended orbital refuge, where her ingrained fear of Takeru—a "Plus Psychic" from Marmelo’s rival caste—fuels tension despite his nonhostility. Marmelo’s societal divide, which pits Plus against Minus Psychics, shadows her interactions.

Entangled in a three-way conflict between Ceres, Gyron’s forces, and Marmelo exile Gashu’s pirate faction, Flore allies with Gashu, driven by vengeance against her father and a resolve to protect her people. This pact sparks an uneasy collaboration between the pirates and Ceres Station to dismantle Gyron’s rule and establish a sanctuary for Minus Psychics.

As the conflict unfolds, Flore’s goals evolve from personal survival and retribution to leading her people’s liberation, navigating internal battles over identity and loyalty amid alliances with former foes. Her wariness toward Takeru slowly thaws into guarded cooperation as shared objectives emerge.

When the narrative pivots to galaxy-spanning threats, Flore’s prominence wanes, though her actions during the Marmelo crisis endure as a catalyst for her community’s fight for autonomy. Beyond her pivotal role in the main series’ second arc, no further appearances or details are documented in ancillary media.
