Description
Leonmitchelli Galette des Rois commands respect as the Princess and leader of the Galette Lion Territory, often addressed as "Your Highness" or affectionately called Leo or Leo-hime. At 16 years old, she shoulders the expectations of her battle-loving people, initially forging a stern demeanor. Her striking appearance features long white hair, piercing yellow eyes, a slight protruding fang, and expressive cat ears capable of flattening to signal dismissal. She typically wears a white strapless top, short jean shorts with crossing straps, armored boots, gauntlets, shoulder armor, and a dark blue cape.

She shares a deep bond with Millhiore Firianno Biscotti, Princess of the Biscotti Republic; they grew up as close as sisters despite their nations' conflicts, with Leo affectionately calling Millhiore "Millihi". A star reading predicting Millhiore's death caused Leo to distance herself emotionally, adopting a cold and ruthless attitude to avert this fate and leading her to initiate wars against Biscotti. Her personality shifted from open and loving to isolated, though she maintained a commanding presence as Galette's leader. Following a fox demon incident, she reconciled with Millhiore and reverted to her warmer personality. Notably, Leo often acts like the younger sibling in their dynamic despite being older than Millhiore. Her speech incorporates masculine tones and archaic pronouns like "washi" and "jaa".

In combat, Leonmitchelli specializes in massive weapons and heavy armor, wielding destructive spirit energy manifested as seal cannons. Her abilities include the **Seal Cannon**, delivering a targeted attack with knockback; **Demonic Flash Wave**, a long-range channeled energy blast; **Lion King Round Seal**, an area-of-effect wave followed by lingering damage; and **Gigantic Explosion**, a high-damage ultimate affecting a large radius. Her passive skill, **Sidestep**, enables evasion of melee attacks. This prowess positions her among Flonyard's most formidable warriors. During the series, she receives a Hero Crystal, enabling a temporary transformation into an adult form with enhanced power.

Her family includes her 13-year-old younger brother, Gaul Galette des Rois, First Prince of Galette, who shares her white hair, cat ears, and yellow eyes and views Biscotti's hero, Cinque Izumi, as a rival. Trusted subordinates include General Bernard Sablage, leader of the Galette Knights and frequent battle commentator. Her relationships extend to childhood friend Leaf, whom she battled in a marriage tournament, noting future potential in their rivalry.

Later developments see Leonmitchelli summon Nanami Takatsuki, Cinque's cousin, as Galette's heroine. Nanami wields the divine sword Exmachina, becoming a key ally and strengthening Galette's ties with other nations through collaborative battles.
