Description
Rem Galleu is a Pantherian from the Gad family in Caliture City. She possesses long black hair reaching her waist, rare black ears and tail among her kind, and expressive green cat-like eyes. Her slender frame shows visible ribs and toned limbs. She typically wears a chest-length vest with shoulder pads, a layered skirt over skin-tight shorts, and a wide leather belt with multiple pockets.

Her personality blends stoicism with underlying vulnerabilities. She experiences significant self-consciousness about her petite chest size, seeing it as a romantic disadvantage. Though initially reserved, she displays snark, quarreling, and pouting around close companions. She exhibits jealousy witnessing affectionate interactions involving Diablo, which evolves from anger to proactive participation. Public affection flusters her, yet she demonstrates deep loyalty, particularly when protecting Krebskulm despite her mission.

Rem bears an inherited curse: the soul of the ancient Demon Lord Krebskulm was sealed within her family line, passed from her mother. To prevent the soul's release upon her death, she left her family and declined Celestine Baudelaire's Mage Association sanctuary offer. She became an adventurer and summoner, seeking independent means to destroy the soul. This quest led her to Starfall Tower, where she coincidentally performed a joint summoning ritual with elf Shera L. Greenwood, resulting in Diablo's summoning. An enslavement spell rebound due to Diablo's magic ring placed collars on both Rem and Shera.

Her abilities leverage her Pantherian heritage, granting superhuman speed and offensive prowess. As a level 40 Summoner with Earth magic affinity, she commands seven primary summons: 《Shadow Snake》 (binding), 《Aslau》 (charged assault), 《Stone Man》, 《Iron Gorilla》, 《Rock Wan》 (earth wolf), 《Dragonfly》 (wind attribute), and 《Sabre Tiger》. She later trains as a Warrior. Key equipment includes the 《Layer of Secret Stone》 (defensive armor), 《Wild Animal's Ring》 (summon enhancement), and 《Magic Hands of the Beast》 (gauntlets boosting speed and beast damage), all gifted by Diablo. When possessed by a fragment of Krebskulm's power, she temporarily manifests the demon lord's martial arts like 《Kikouha》 and 《Rasensou》.

Her character development centers on reconciling her mission with newfound relationships. Though initially viewing Diablo as a tool to eliminate Krebskulm, she gradually develops genuine affection for him. Her dynamic with Shera evolves from rivalry over summoning rights to a competitive yet caring partnership. A critical shift occurs when Diablo partially separates Krebskulm's soul from Rem, leading to Krebskulm manifesting as a separate childlike entity. Despite vowing to destroy the demon lord, Rem instinctively protects and nurtures Krebskulm, showcasing maternal conflict and loyalty. This bond deepens, with Rem prioritizing Krebskulm's safety even at personal risk.

Rem's familial connections include her aunt Solami Galleu, a formidable martial artist who later trains Diablo. Solami's revelation about Diablo's dual engagement rings—one gifted to Rem and another to Shera—causes temporary marital confusion, resolved when Diablo commissions a new ring exclusively for Rem. This reinforces their committed relationship within the group dynamic.
