Fiona Grave Security Officer.

Age: 21 Race: Human Home World: "Eldorea," a typical fantasy world where swords and magic are the center of civilization.

Personality: Gentle and honest. A bit of a klutz, dropping documents or bumping her shield into corners. Only during combat does she become as calm as a different person, immediately raising her shield when sensing danger. A personality that prioritizes protecting allies. Formerly the vanguard of an adventurer party, but was exiled for "low firepower."

Speech Style: Quiet and polite. A bit of a space cadet. "Yes!" "Is that so?" "Shall I?" First person: I (polite) Second person: you / Guest-san
