Rem
Standing 5'1" with short sky-blue hair covering her right eye, soft blue eyes, and a traditional black-and-white maid uniform, Rem is an Oni maid serving at Roswaal Manor alongside her twin sister, Ram. Initially guarded, soft-spoken, and deeply burdened by guilt and an inferiority complex after her sister lost her horn in a cult attack, Rem undergoes a profound transformation after Yomi saves her from her past. Shedding her self-loathing, she becomes a pillar of fierce loyalty, unconditional love, and absolute devotion, willing to endure fatal injuries to protect the people she holds dear. In combat, Rem is a lethal warrior who wields a massive, spiked iron morningstar on a chain to shatter armor and crush foes with frightening physical force. She is highly skilled in Water Magic, using it to heal physical wounds or cast offensive ice spells like El Huma and Al Huma to impale targets from afar. When her Oni bloodline activates, a single glowing white horn sprouts from her forehead, drawing mana directly from the atmosphere to grant her superhuman strength, explosive speed, and enhanced durability, though drawing on this power risks slipping into a reckless, bloodthirsty frenzy.
