Elf Suzailgillazegallnelbuzegillreagranzelga Elga hails from a royal elven line. She possesses long blond hair typically in twin ponytails, green eyes with prominent blond eyelashes, and wears a black-and-brown dress, black pants, and red shoes. Her relic armor materializes or vanishes on command, and an anti-mind-control jewel adorns her headband. Her personality embodies the tsundere archetype, masking affection with initial hostility. She is frequently rude toward Yousuke Shibazaki ("Uncle"), partly due to his social unawareness, and visibly blushes when he compliments her. She exhibits intense jealousy over his interactions with other women, sometimes leading to emotional breakdowns. This possessiveness extends to cosmic rings, symbols of romantic commitment in her culture, which Uncle unknowingly distributed during their travels. They first met during her battle with a Poison Dragon; Uncle exploited a weakness she created to strike the final blow. After rescuing her, he later saved three people from monsters only to be betrayed and thrown off a cliff. Elf intervened, nursing him back to health. In gratitude, Uncle gave her a cosmic ring, which she misinterpreted as a marriage proposal, sparking her romantic attachment. Subsequent encounters deepened her feelings: she defended him against townspeople accusing him of causing a monster siege, though he fled after misinterpreting her request for a shared meal as extortion. During a festival, she escorted a drunk Uncle to his room, only for him to dismiss her abruptly, leaving her distraught. Her relationships with other women are complex. She bonded with Mabel Laybelle after discovering her in a compromised position with Uncle, though jealousy resurfaced upon seeing Mabel's cosmic ring. She similarly viewed Alicia Edelsia as a rival, sabotaging her moments with Uncle. A significant shift occurred when she cared for Uncle after subduing his dragon transformation, culminating in a shared hot-springs visit. Though interrupted by eavesdroppers, Elf affirmed their relationship when Alicia speculated they were a couple, showing rare vulnerability. Later, after killing soldiers planning to ambush Uncle and Mabel, she confronted him about their closeness. This led Uncle to reveal his real name and offer the nickname "Sui" (meaning "green," referencing her eyes). She initially rejected it due to clan traditions but privately accepted it after he emphasized her personal choice over familial expectations. Her abilities include flight, swordsmanship, sniping, and wielding a vibration-based magical sword that converts into an energy sniper rifle. She taught Uncle storage magic. Key possessions are the cosmic ring, Uncle's jacket (which she treasures after he covered her during nudity), and her relic armor. A notable incident involved an aphrodisiac arrow; after Uncle offered to "remove the poison," she knocked him unconscious and used her anti-mind-control jewel, resulting in implied intimacy. She also faced a magical contract binding her to mercenary leader Hagen as collateral for a lost cosmic ring. Uncle annulled it by offering Hagen another ring, further straining their relationship due to his casual distribution of the rings. In broader narratives, including crossovers, she maintains her tsundere demeanor and combat role. Her development shows gradual emotional openness, particularly in accepting "Sui" and affirming her bond with Uncle, though his obliviousness perpetuates their unresolved dynamic.
