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 Lurolona Village 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.

Volume 10
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 Muso style under the instructor's tutelage. Impressed by Eclair's enthusiasm to learn, the instructor taught her the sword basics of the style.

Volume 11
After Ren unlocked his two curse series weapons and started rampaging through Melromarc, Eclair took the responsibility to stop him. The two duelled and Eclair was eventually able to defeat Ren using the Hengen Muso techniques she had recently learned. After Ren gave up and started dealing with the backlash of using curse series weapons, Eclair took it upon herself to take care of him. She also trains him how to properly use a sword and Hengen Muso.

Volume 13
Since the reconstruction of Lurolona Village had begun, Eclair would find ways to avoid her responsibilities by training - leaving Melty in charge of the actual work. Finally, Naofumi recognized this as an ongoing problem and demoted Eclair from her position and put Melty in the role instead since she was already doing all the work. Eclair initially protested but acknowledges that this was due to her own actions.

Volume 17
Since the time that Eclair had taken responsibility for helping Ren from his curse, Ren had slowly started to develop feeling for Eclair. However, these feelings were seemingly reciprocated since Eclair was "married" to the sword. Regardless, Naofumi encourages Ren to pursue his relationship with Eclair.

Volume 20
During Naofumi's absence from the village for his second trip to Glass' World, Ren had taken responsibility of governing the village. However, the stress become too much and he become physically and mentally overwhelmed. Eclair was forced to assist Ren.

After Lurolona Village was sent back in time by an experimental weapon from the Army behind the waves, Eclair was party of the group sent back in time. With her noble education, Eclair helped everyone realize that they were sent back in time and that they were working with a legendary shield hero named Mamoru. As they fought against enemies, Eclair realized that she was falling behind and was becoming less useful to the group. She then asks Ren to help her become stronger.
