Eclair Seaetto/Chronology

Volume 6
Naofumi requested trainers to help the heroes to improve their skills. She was asked to act as a martial arts instructor for Naofumi's slaves in Rock Valley to prepare for the next wave. She along with other experts helped to improve the skill of Naofumi's party.

Ren looked down on her skill thinking that because he was a hero and a higher level than her she had nothing to teach him and he stated as much in response to his statement and to prove him wrong she challenged him to a duel. during the duel using pure skill, Eclair began to push Ren back which upset him and because of this, he used a skill which was in violation of the rules of the duel. Though he technically beat her, because he broke the rules and by his own admission (after the queen called him out on it) he had lost the fight. Afterward, the three heroes agreed to participate in the training.

The Female Knight participated on the front lines of some of the fights against the Spirit Tortoise. Raphtalia gave the credit of her success to Eclair for training her. Once again she was taken aback by Naofumi's attempt to claim the treasure of the spirit tortoise and assisted in preventing the coalition army from taking the treasure.

After returning from the other world, Naofumi highly criticized Eclair's naivety in rebuilding the territory and took it upon himself to rebuild it. Shortly after his village was attacked by 50 or so slave hunters, Naofumi apprehended all of them and Eclair identified at least a few former soldiers in them who were responsible for the selling the former villagers to the slave auction. Eclair revealed the truth about their punishment and the pressure in favor of the culprits by the nobles against their punishment. Eclair was even more shocked by Naofumi's way of handling things of planning to sell all of the slave hunters to Siltvelt (a demi-human nation which mistreated humans) and use that money to buy all Raphtalia's villagers.

But she remained silent as they might able to escape the grasp of the royal with the help of nobles and they will get the same taste of their victim's fate, it also gave them the required money to buy back the former villagers who were sold as slaves. This incident also acted as a warning which scared away any other slave hunters who may have wanted to attack the village. Eclair for the first time saw the benefits of Naofumi's realistic approach as opposed to her idealistic one.

Later when Granny was appointed as the Battle Instructor and took some of the residents to the mountains for training, Eclair took a "vacation" to follow her so she could learn the Hengen Musou style under the instructor's tutelage. Impressed by Eclair's enthusiasm to learn, the instructor taught her the sword basics of the style.

She then took on the responsibility of capturing Ren herself by using her Hengen Musou techniques she had recently learned.
