Milano Entolasia, granddaughter of the royal butler Jodo Entolasia, serves as Princess Alita Forland's maid. When Dr. Akamashi launches a coup against the Forland kingdom, Milano volunteers to act as Alita's decoy. Disguising herself as the princess, she creates a diversion to enable Alita's escape, an act of sacrifice that leads to her death during the coup. This loss leaves Alita shattered and fuels her subsequent actions.

After fleeing the coup, Alita experiences a near-fatal encounter with the bounty hunter Falis, resulting in an accidental body swap between them. With Milano deceased, Alita adopts Milano's identity, becoming Falis's maid. She aids Falis, who now inhabits Alita's body, in governing the kingdom and defending it from dangers. Initially burdened by grief over her father and Milano, Alita exhibits moments of fragility and uncertainty. Yet, while maintaining the Milano persona, she cultivates resilience and determination, especially in her commitment to protecting Falis and the kingdom.

A critical juncture arises when Alita's brother, Prince Kaito, returns as the traitorous "Dark Knight." To shield an injured Falis, Alita (still posing as Milano) replicates Milano's original sacrifice by impersonating Princess Alita, drawing Kaito away. During their confrontation, she openly denounces Kaito as a disgrace to their royal blood, showcasing her newfound boldness and unwavering loyalty to Falis. This shared experience of sacrifice and protection forges a deeper bond between Alita and Falis, solidifying Alita's dedication to her role as Milano for the kingdom's stability.
