Lashara Moon, daughter of the Galactic Emperor, earns renown as the "Flower of the Galaxy" through her exceptional beauty. Initially, she harbors intense romantic feelings for Sir Papacharino Nanadan, idolizing him as a hero. Her devotion drives her to gift him twenty-eight doll-like assistants called the Pochis, with Pochi #1 serving as their leader and sharing a particularly close bond with Lashara. She abandons her home to pursue Papacha.

Discovering Papacha's true nature as a womanizer with thirteen wives—who views her merely as a harem trophy—plunges Lashara into severe emotional trauma. This revelation spirals into deep depression and suicidal contemplation. Her anguish intensifies when Papacha callously discards Pochi #1 after a failed mission.

A pivotal shift occurs when Photon Earth rescues Pochi #1, who then merges with Lashara. This fusion stabilizes her emotional state and redirects her affections toward Photon. She subsequently joins Photon’s adventures alongside Keyne Aqua and Aun Freya.

Later revelations expose that the Galactic Emperor switched Lashara at birth with Keyne Aqua. Consequently, Lashara lacks biological royal lineage, while Keyne emerges as the true princess, recontextualizing Lashara’s upbringing and status.

In the story’s conclusion, Photon inadvertently inscribes "baka" (idiot) on Lashara’s forehead. Under galactic customs, this mirrors his earlier accidental marriage to Keyne, forming an unintended marital bond. Lashara’s comprehension and acceptance of this new dynamic remain implicit.
