Ram is the older twin sister of Rem, both members of the Oni Tribe. Born on February 2nd and aged 17-18, she has pink hair covering her left eye, red eyes, and stands 154 cm tall. She and Rem narrowly escaped death at birth due to the tribe's taboo against twins because Ram demonstrated exceptional talent, hailed as the "reincarnation of the Oni God." Her life in the Oni village ended tragically at age eight when Witch Cultists slaughtered the tribe. While protecting Rem during the attack, Ram's horn was severed, causing the permanent loss of most of her power and resulting in chronic pain and weakness. Rescued by Roswaal L. Mathers, Ram later formed a pact with him to ensure Rem's safety, agreeing to support his goal of killing the Divine Dragon. Ram displays a haughty, sarcastic demeanor, often appearing lazy or dismissive, particularly towards Subaru Natsuki, whom she nicknames "Barusu." Despite this outward coldness, she possesses a deeply caring and self-sacrificing nature, prioritizing others' well-being while hiding her physical suffering. She is intensely protective of Rem, constantly supporting her to alleviate Rem's inferiority complex; Ram deliberately underperforms in tasks like cooking to allow Rem to shine. She develops complex loyalty and eventual love for Roswaal, striving to free him from his obsessive pursuits even at personal risk. Her insight and fairness are frequently noted, with the series' author describing her as the "kindest" character. Lacking her horn requires Ram to receive regular mana infusions from Roswaal to survive, as its absence causes chronic pain and fatigue, limiting her physical endurance. Despite this, she retains formidable abilities: She manipulates wind magic to create blades, using spells like "El Fura" for precise strikes, "Ul Fura" for erratic attacks, and "Al Fura" for devastating area assaults; she can augment weapons or mimic techniques like the "invisible blade." Her Clairvoyance (Senrigan) allows shared vision with others matching her wavelength for remote observation, though it strains her body, causing blood tears and tremors. A telepathic Synesthesia bond with Rem enables emotion-sharing and, temporarily, borrowing Rem's horn to amplify her strength, though this causes severe backlash like vomiting blood. Even at 20% of her original power, she remains a capable fighter, using wind magic for flight and strategic advantages. Had she retained her horn, she would have rivaled Reinhard van Astrea, one of the world's strongest warriors. Her story spans multiple arcs: Serving as a maid at Roswaal's mansion in early arcs, she masks her pain, distrusts Subaru initially but later acknowledges his value; Rem's death devastates her, nearly breaking her sanity. In Arc 4 at the Sanctuary, she aids Subaru and allies against threats, confronting Roswaal about his destructive ambitions, revealing her love for him and risking her life to redirect his path. Traveling to the Pleiades Watchtower in Arc 6 wearing desert-adaptive attire, she reacts with denial and aggression when Subaru loses his memories, reflecting her reliance on him as the sole person remembering Rem. In Arcs 7–8 in Vollachia, she cross-dresses as "Natsumi Schwartz" for subterfuge; Olbart Dunkelkenn's technique infantilizes her to age 10, altering her appearance temporarily before she reverts and continues supporting allies in conflicts like the Bloodless Siege of Guaral. Minor details include her proficiency with chopsticks, alcohol tolerance, and signature dish of steamed sweet potatoes. She appears in crossover media like *Isekai Quartet: The Movie – Another World*.
