Fiel Nirvalen is a side character in the series No Game No Life. An elf girl who is Chlammy Zell's game partner, as well as the one who helps her cheat using her elven magic. It is subsequently revealed that Chlammy is actually her family's slave. Despite this, they hold a close relationship between each other.
- She begged Sora to restore Chlammy's memories after the latter won them in a game. Believing that Sora's going to fulfill his words to unite all races, she now works with Chlammy to claim the leadership of Elves as she cares more about Chlammy than her own race.
- She greatly cares for Chlammy, even risking her life for her during the Reversi game. Despite having pride as an elf, she is willing to swallow it for the sake of Chlammy.
- She is a hex caster (able to cast and maintain up to six spells at once), a very rare capability that only an extraordinary few possess. However, to protect and aid Chlammy, she hid her magical prowess from the rest of the elves, resulting in them believing Fiel to be a poor magician and a disgrace to the Nirvalen name.
- Her weakness: She is very protective of Chlammy and would go to great lengths to keep her safe. This could prove to be a possible extortion factor if Chlammy was ever to be threatened or taken hostage.
- She offered Chlammy to have her after a bath.
- The way Chlammy was upset about how she was mean to Stephanie, and secretly practicing how she's apologize to Stephanie is what she finds to be really cute.
- In one of the chapters of the visual novel, she slept next to Chlammy.
