Movie
Description
Feel Nilvalen is an elf from the No Game No Life series, specifically appearing as a character in the main storyline rather than the prequel film Zero, though she is a descendant of the elf Shinku Nilvalen who fought during the Great War depicted in that movie.

Feel Nilvalen has the physical appearance of a young girl of about fifteen years, but her actual age is fifty-two. She possesses long, golden blonde hair, often styled with a pink ribbon keeping a portion of it in a plait, and her distinctive eyes have dark blue irises with pink, clover-like pupils. As an elf, she has long, pointed ears and she has a notably large bust. Her attire typically consists of an elegant dress with detached sleeves, reflecting her high social standing.

Feel was born into the Nilvalen family, a prestigious and powerful house that has held a seat in the upper senate of the elf nation of Elven Gard for generations. Following the death of the previous head of the family, she became the de facto head of the Nilvalen household and acted as a substitute upper senator.

Despite her noble background, Feel is known within her society as the Disgrace of the Nilvalen family. This is a carefully constructed facade. She publicly presents herself as a poor magician who can only manage two spells with the aid of a magical amplifier, which led to her expulsion from the prestigious magical academy known as the White Tower of Trees. In reality, she is an extraordinarily powerful sorceress. She is a hex caster, meaning she can simultaneously cast and maintain up to six spells, and she possesses the secret ability to cast a sevenfold magic as her ultimate trump card.

Feel Nilvalen's personality is marked by a sharp contrast between her gentle, mild-mannered exterior and her cunning, strategic mind. She is an expert in psychological warfare, with abilities that are considered equal to the protagonist Sora. She typically speaks with a soft voice and maintains a calm and friendly demeanor, which allows her to hide her true intelligence and capabilities from her political rivals. Beneath this surface, she is fiercely dedicated to her goals and holds deep-seated pride in her heritage, though she is willing to set aside that pride for the sake of those she cares about. She harbors a notable dislike for the Flugel race, the angelic beings, due to the heavy losses they inflicted upon the elves in the past.

Her primary and most defining motivation is her unwavering devotion to Chlammy Zell. Chlammy is, officially, her family's slave, a fact that Feel personally opposes. They present themselves as master and servant in public, but in reality they are close friends and partners. Feel's ultimate priority is protecting Chlammy, and she has stated that she would let her own nation be destroyed if it meant saving her. This bond is so strong that the siblings Sora and Shiro have remarked that their relationship resembles that of a mother and daughter.

Within the story, Feel Nilvalen plays the role of a hidden genius operating from within the heart of the elf political establishment. She secretly supports the liberation of slaves, a goal that runs directly counter to the policies of Elven Gard, which encourages the enslavement of lower races. After aligning with Sora and Shiro, she becomes a double agent, feeding misinformation to her own government to aid their plans to unite all sixteen races of Disboard. As Chlammy's gaming partner, she provides magical support, often cheating subtly during games to ensure Chlammy's victory, and served as a magical relay during a crucial challenge against the Werebeast race.

Her key relationships are central to her character. Besides her profound connection with Chlammy Zell, her allegiance eventually shifts towards Sora and Shiro, known as the Blank siblings. While initially dismissive of the Imanity, she comes to trust Sora's vision after he returns Chlammy's memories, agreeing to work with him as a spy. She is also the descendant of the legendary elf Shinku Nilvalen, a mage from the Great War who was one of the creators of a devastating superweapon and was known as an octo caster, capable of maintaining eight spells.

Feel Nilvalen undergoes a distinct development throughout the story. She begins by hiding her immense magical power and strategic mind, pretending to be incompetent to avoid suspicion. She lives a dual life, secretly sabotaging the slave system of her own nation for the sake of her friend. After joining forces with the protagonists, she transitions from a secret protector to an active agent of change, using her political position and magical abilities to directly work towards a new order where the races can coexist.
