Similar to her predecessor, Gemini Saga, she is afflicted by a split personality, one of which manifests as a gentle, refined and loving young woman, who calls herself the Loving Paradox (in Japanese: 愛のパラドクス Ai no Paradokusu, and the other manifests as a wrathful embodiment of hate, calling herself the Hateful Paradox (in Japanese: 憎しみのパラドクス Nikushimi no Paradokusu). The Loving Paradox is a selfless woman only believing in her own form of love and is overly affectionate to her opponents. The Hateful Paradox is the complete opposite during battles, she is very ruthless and vengeful, seeking to end the life of her opponents the moment they refuse her love.
