Liliruca Arde, known as Lili, is a Pallum standing 110 cm tall with chestnut hair and brown eyes. She wears a slightly torn red-and-white hooded top revealing her midriff, an unbuttoned red skirt, black tights, light brown boots, and long gloves. Her Pallum heritage provides sharp eyesight, amplified by her falna.
Born to Soma wine-addicted parents in the Soma Familia, she earned money for them from age three. After their deaths in the Dungeon, the Familia neglected and mistreated her. Struggling as a weak adventurer, she became a supporter but faced exploitation and abuse from others, fueling deep distrust and hatred toward adventurers. She resorted to theft and deception, using transformation magic to disguise herself and steal from those she supported. A brief respite at a flower shop ended when the Soma Familia targeted her benefactors, reinforcing her isolation.
She first encountered Bell Cranel while attempting to deceive him and steal his weapon. His consistent kindness—sharing spoils equally and prioritizing her safety—made her question her actions. When adventurers betrayed her during a theft, Bell rescued her from Killer Ants despite her earlier betrayal. This shattered her worldview, leading to tearful remorse and a vow never to betray him again.
She joined the Hestia Familia after escaping the Soma Familia. Kidnapped later by Soma members, she resisted Soma wine, symbolizing her break from the past. As treasurer, she managed finances meticulously, avoiding waste and favoring cost-effective solutions. Her survival-honed tactics made her the Familia’s chief strategist. She planned their War Game strategy against Apollo Familia, using Cinder Ella to infiltrate and sabotage the enemy. She later trained under Finn Deimne and Daphne Lauros to refine her command skills.
Her abilities include:
- **Cinder Ella**: Transformation magic to assume forms of similarly-sized entities, replicating physical traits limited by her status. Used for espionage before joining Hestia Familia.
- **Artel Assist**: A skill enhancing carrying capacity, vital for her supporter role.
- **Command Call**: A rare skill gained at Level 2, allowing mental relay of orders across distances to those sharing her falna. Enabled battlefield coordination during conflicts like the Faction War.
- **Combat Proficiency**: Wields crossbows like Sciurus Walnut for ranged support and tactical items like poison bags. Post-Level 2, her physical capabilities surpassed Level 1 adventurers despite her non-combat focus.
In the Xenos arc, she advocated caution, opposing sheltering Wiene due to perceived Familia risks, reflecting pragmatic logic. Her leadership expanded during the Faction War against Freya Familia, commanding alliance forces via Command Call and enemy tactic insights. She achieved Level 2 after exceptional growth, becoming one of few Pallums to do so. Her alias "Little Marshal" acknowledges her strategic prowess.
Within Hestia Familia, she holds unwavering loyalty to Bell, evolving into romantic feelings. She clashes with Hestia over Bell’s attention but collaborates for his protection. She maintains a teasing dynamic with Welf Crozzo regarding finances. Finn Deimne proposed after witnessing her courage, though she declined to stay with Bell.
Trivia notes include her magical motif referencing Cinderella, her original web novel portrayal as more mischievous, and lore suggesting she is the reincarnation of legendary heroine Fianna.
