Alma Lepucius is the third daughter of the Lepucius noble house. She bears the Second Crest, historically called the "Crest of Might," which specialized in long-range, high-powered magical attacks. In her era, degraded magical knowledge and reliance on incantation magic lead to its mislabeling as the "Crest of Standard," limiting its combat potential.

Her primary combat role is that of a mage marksman, employing archery enhanced by her magic. She fires trick arrows imbued with effects like poison or homing capabilities through magical enhancement. Her combat effectiveness relies significantly on her partnership with Lurie Abendroth, who provides magical support and enchantments for Alma's arrows.

Alma displays a tomboy personality, contrasting with Lurie's more girlish demeanor. She demonstrates strong loyalty to Lurie, having abandoned an arranged marriage chosen by her father. This defiance caused her to flee her home alongside Lurie, subsequently joining Matthias's party.

A notable personal trait is her severe lack of culinary skill; her cooking is inedible, resulting in a ban from her family's kitchens. This extends to group settings, where even Iris, a dragon in human form, cannot tolerate Alma's food.

Within Matthias's group, Alma frequently observes and comments on the developing relationship between Lurie and Matthias, often playfully teasing their mutual attraction. She is consistently portrayed alongside Lurie, with their companionship being a recurring narrative element.

No concrete information exists regarding her involvement in spin-off media, alternate timelines, or significant character evolution beyond this established role.
