Ximena Luis, a civilian co-owner of a Valiante Kingdom capital inn with her father, discovered Germán Luís naked and vulnerable during their first meeting, offering him a sheet to preserve his dignity. She later nursed him through life-threatening injuries from Horror battles, applying medical expertise to prevent complications. Their time together forged a mutual respect and deepening emotional bond, defying Germán’s usual philandering tendencies.

Prior to Germán’s departure on a critical mission, Ximena confessed her feelings, culminating in a passionate encounter that left her pregnant. After his death, she gave birth to their son Roberto, the future heir to the Zoro armor. Ximena voiced reservations about Roberto embracing the Makai Knight path, hoping he might avoid its emotional toll and physical dangers, yet acknowledged the weight of Germán’s legacy.

When masked thralls under Horror Nigra Venus kidnapped Roberto, Ximena chased the abductors but fell behind. León stepped in, vowing to retrieve the boy. Following the Horror’s defeat and Dario Montoya’s downfall, Ximena reunited briefly with a resurrected Germán, aiding the mission. Their moment shattered when Dario resurfaced as a Horror, prompting Germán’s final sacrifice to shield his family. Grieving yet resilient, Ximena drew strength from Roberto’s resolve and ally support.

Amid these trials, Ximena remained fiercely protective of Roberto, balancing maternal care with harsh realities. She inherited Jiruba, Germán’s Madōgu bracelet, using it as a protective charm against Horrors. Her bond with Germán defined her journey—fleeting moments of connection intertwined with enduring loss and unwavering duty.
