Description
Luna Shirogane, internationally recognized as Luna Platz, holds the position of class president for Echo Ridge Elementary's Class 5-A, earning the nickname "Prez" among classmates. Her appearance combines distinctive dark green or blonde hair styled in large pigtails, brown eyes, a formal blue dress with a white upper section, a red scarf, a green gem adornment, cyan tights featuring yellow linings, and blue footwear.

Initially perceived as bossy and demanding, Luna exhibits strong leadership skills, compelling peers to tackle tasks they avoid. This perfectionism arises from parental pressure to meet rigorous standards. Beneath her assertive exterior, she displays kindness, fierce loyalty, and deep concern for friends' safety, often prioritizing their welfare above her own. She harbors an affinity for cute objects, exemplified by her non-combat rabbit-like Wizard partner, Vogue.

Key events shape her journey:
In the first game, Luna persistently urges Geo Stelar to return to school after his father's disappearance. Witnessing Mega Man's heroism during the Taurus Fire incident sparks her admiration for the hero. Family conflict erupts when her parents plan her transfer to another school, deeming her friends detrimental to her potential. Emotional turmoil drives Luna to fuse with the FM-ian Ophiuca, becoming Queen Ophiuca to confront her parents. Following Mega Man's intervention, she reconciles with her family, discovers Geo's dual identity, and forms a BrotherBand with him.

The sequel sees Luna kidnapped by Dark Phantom, who exploits residual Ophiuca data within her to forcibly recreate Queen Ophiuca. Rescued by Geo, she refuses to leave him during an OOPArt-triggered crisis, activating a Link Power that stabilizes him and unlocks new abilities. She later accompanies Geo worldwide to rescue scattered friends, publicly affirms Zack's value to their group, and restores amnesiac Bud's memory using a Ginger Beef bowl and affectionate encouragement.

During the third installment, Luna campaigns for student body president with her "Luna 4 Prez" team. After Jack Corvus and Queen Tia reveal their identities, Joker attacks and deletes her, fracturing her consciousness into six EM-wave fragments. Geo retrieves these Luna Frags, enabling Dr. Goodall to reconstruct her. Post-recovery, Luna acknowledges owing her survival to collective efforts. Elected student president, her inaugural decree promotes school-wide unity through teacher-student collaboration. An optional Alohaha chapter scene depicts her sharing a heartfelt moment with Geo, where he credits her unwavering support as essential to his perseverance as Mega Man.

Romantic tension surfaces through her confessed feelings for Geo beyond her Mega Man fandom, highlighted by narrative notes referencing a boy she likes "almost as much" as the hero. This subplot intertwines with a Betty and Veronica dynamic involving Sonia Strumm.
