Motoyasu Kitamura: In alternate timelines of the spear hero’s story, she escapes his typical gender prejudice and works with him as an equal, often guiding him in negotiations.

“No matter the circumstances, I cannot stand by and watch my people suffer.”
The Rising of the Shield Hero
Eclair first appears midway through the story, sent as a messenger to Naofumi’s village.
Due to her poor self-introduction, Naofumi simply refers to her as the "female knight."
She was previously imprisoned for taking vigilante action against state-sanctioned slave hunts.
After her release, she joins Naofumi to gain experience in governance and sword training, and acts as a counselor for the heroes during key battles like the Spirit Tortoise incident.
Eclair also attempts to mediate when Naofumi is overcome by rage against Ren Amaki, helping him resolve inner conflicts and restoring peace among the heroes.
Despite her stern nature, Eclair sometimes becomes confused by Naofumi’s methods, attempting to balance her own ideals with the messy realities of rule and war.
She stands as Ren’s partner through various battles—though strictly in a professional sense—and ultimately acquires the Vassal Katana, proving her adaptability and strength.
In the web novel, she outmatches Ren in pure sword skills, and in the published light novels, she appears earlier and helps instruct the heroes.

During the war between Melromarc and Siltvelt, she commands Melromarc’s forces and helps deliver key messages from Queen Mirellia.
In one timeline, she tragically dies in prison after being tortured by the Three Heroes Church, but in a later attempt, Motoyasu saves her.
She continues to serve as a diplomatic and tactical leader, tackling issues unresolvable by force, and forms close bonds with new demi-human allies in the region.
Eclair also learns about the legacy of a warrior lizardman connected to the Shield Hero, deepening her respect for those who fought for their ideals.
She plays a pivotal role in the final battle, overwhelming even high-level enemies with skill and experience, and demonstrating her growth as a knight and leader.
