Description
Rafinha Bilford, nicknamed Rani, is the daughter of Marquis Bilford and Irina Bilford, and the younger sister of Rafael Bilford. Her maternal cousin is Inglis Eucus, the series' protagonist, sharing a close bond since childhood. Rafinha possesses short black hair, blue eyes, and a modest physique, often contrasted with other characters' more pronounced bust sizes. She typically wears the Royal Knight Academy uniform.

Her personality blends a strong sense of justice with a cheerful, lively demeanor, making her a mood-maker. She exhibits a perverted streak, frequently groping Inglis during shared baths and expressing envy over Inglis' larger bust, extending this behavior to others like Leone Olfa. Rafinha is fiercely protective, demonstrated when defending Leone against Liselotte Arcia's derogatory comments about Leone's family. She initially disliked Liselotte for this but reconciled after Liselotte acknowledged her wrongdoing. She shows embarrassment when given nicknames like "Little Demon" by her senior, Yua, due to her spirited nature.

Key events mark her youth: at age five, she witnessed the warrior Rahal bullying her brother Rafael, leading to Inglis defeating Rahal. At twelve, she joined Inglis and Eris to confront Rahal again, now transformed into a monstrous Highlander; Inglis killed him when reversion proved impossible. By fifteen, Rafinha enrolled in the Royal Knight Academy alongside Inglis, aiming to become a Holy Archer. Her age progresses to sixteen in later light novel volumes.

She wields an Energy Bow artifact, manifesting arrows of light without physical strings or quivers, leveraging her Light-element Rune. Her combat abilities include exceptional marksmanship and the "Rain of Arrows" technique, where a single arrow disperses into multiple piercing beams. While her magical prowess is significant, it is less potent than Inglis'. She often provides strategic coordination in battles, particularly with Inglis, who typically handles the most formidable threats.

Relationships define much of her arc. She advocates for Inglis to marry her brother Rafael to solidify their familial bonds. Her friendships include Eris (initially mistaken as hostile), Leone Olfa, Pullum, Lahti, Cyrene (nicknamed "Rin"), Liselotte Arcia (after reconciliation), Yua, and Ripple. She dislikes dishonorable individuals, exemplified by her enmity toward Rahal, the traitor Leon Olfa, and the Hyrule Menace Sistia Rouge, who once threatened her life to escape Inglis.

Trivia includes her birthdate (April 5th) and a running gag where Cyrene shows no interest in her cleavage due to her flat chest, unlike other female characters.
