Saphir operates as one half of an antagonistic duo alongside Rubis, both targeting GTO Chief Hiver within the same group as his assassins. Her combat abilities center on generating and manipulating ice, contrasting with Rubis' feral, tiger-like transformations to create complementary fighting styles. They directly assault Ascoeur and Q-feuille during a babysitting assignment for Di-air, where Saphir deploys her freezing attacks. The intervention of GTO security forces forces their retreat. The duo later resurfaces when Rubis experiences a "Balloon Belly" incident, confirming their ongoing partnership. Saphir's name, derived from the French for "Sapphire," follows the series' theme and pairs directly with Rubis, meaning "Ruby." Her appearances remain confined to these antagonistic engagements.
