Eclair Seaetto

Her appearance is that of a standard female knight from a game with blue eyes and strawberry-blond hair. She has a face that could rival Raphtalia’s in beauty, but she looks like she would fit the role of a Wicked Queen perfectly somehow. She is introduced in chapter 137 accompanied by other knights, one of whom is identified as part of the volunteer army that helped Naofumi during the third wave. She was often refereed by Iwatani Naofumi as the Female Knight.

Background
Eclair's father spent his life building a relationship with demi-humans and, after he died, Eclair later chose to follow her father's footsteps. In "Start Over of The Spear Hero" it was revealed that, during the Queen's absence, Trash had abused his authority where, because Eclair had punished the knights of Melromarc who hunted demi-humans, he revoked Eclair's knighthood and imprisoned her. It was assumed, in the original timeline, she managed to stay alive as Mirelia returned where the Queen freed Eclair, and restored her status, while Trash was later punished for the injustice he caused for Eclair.
