Atla Fayon/Chronology

Volume 11
Atla was first found as the property of the Zeltoble slave traders. She was blind and dying of a genetic disorder but was being cared for by her brother Fohl who fought in the coliseum. Impressed by Fohl's stats and racial characteristics, Naofumi decides to purchase both of the siblings. Naofumi uses incredibly potent and expensive medicine to starts a healing regimen for Atla. Both Fohl and Atla are set at Naofumi's slaves and are sent to his village.

At the village, Atla makes a nearly full recovery. When her bandages were removed, her beauty struck everyone. In order to help Naofumi, Atla determined that she wants to fight, much to Fohl's despair. She decides that if Raphtalia is Naofumi's sword, she wants to be his shield.

Atla tagged along with Naofumi, Fohl, and Sadeena for their trip to reset Fohl and Sadeena's levels. Before heading to the Melromarc hourglass, Fohl and Atla came across Trash. Trash immediately started raving once he saw Fohl and then calmed with a sad look once he saw Atla. The queen explains that the Hakuko killed Trash's family except for his blind sister, which Atla closely resembles. Trash's sister went missing, presumed dead by most. It is believed that Trash's sister is Atla and Fohl's mother. When discussing their family, Fohl reveals that their parents died when they were young and that their grandfather, Trash's enemy, was supposedly impressive.

After Atla was tested by the old lady, Naofumi found that Atla had a high aptitude for the Hengen Musou style. Using Hengen Musou, she is able to use it to 'see' even though she is blind and strike critical points on opponents. With Fohl's level reset, Atla was clearly the better fighter.

Volume 12
In order to teach Naofumi how to understand Hengen Musou and life force, the old lady tells Naofumi to spar against Atla. To keep Atla's obsession with Naofumi in check, Raphtalia also stayed with them to train. Outside of training, Fohl was tasked to keep Atla in check.

During the Demon Dragon Emperor incident where Gaelion was taken over by the Demon Dragon Emperor shard that he consumed, Atla was able to stop Gaelion from draining levels from Filo. She also went with Naofumi to retrieve Gaelion. When it came time to fight the Demon Dragon, Atla was chosen to receive the Descent of the Thunder God buff due to her defense-rating attacks. She was able to destroy his barrier and cause massive damage while no one else could damage the dragon before. Through teamwork, they were able to defeat the Demon Dragon and save Gaelion and Filo. It became clear, however, that the power gap between Atla and Fohl kept on growing larger.

When the attack force from Q'ten Lo attacked Naofumi's village, Atla successfully helped in its defense until all the enemies were defeated.

Volume 13
In order to reach Q'ten Lo, Naofumi and his party were forced to make their way through Siltvelt. Since Atla and Fohl's family was from Siltvelt, they were chosen to join the trip. Due to the Hakuko's previous power in Siltvelt, Naofumi was forced to explain to their hosts that neither Atla nor Fohl wants the throne.

Jaralis and his companions try to poison Naofumi, Fohl, and the rest of their group. After they are discovered, Atla calls out Jaralis and the rest of the leadership as selfish and as ones who have strayed away from the purpose of Siltvelt - to worship the shield hero. The surrounding leadership is impressed and convinced by her ferocity and logic. However, Jaralis is upset at this confrontation and proposes a duel: He and his companion will fight the two 'half-breeds'. Fohl and Atla, who both accept. After Fohl was targeted by Jaralis to fight one-on-one, Atla got his companion - a massive minotaur. Atla easily beat the monstrous war hero by using her Hengen Musou. With Atla and Naofumi's help, Fohl was able to defeat Jaralis using the legendary Assault of the Ferocious Tiger Tyrant attack.

The leaders of Siltvelt convinced of the legitimacy of Naofumi, Atla, and Fohl, prepared everything required for their group to travel to Q'ten Lo. Atla was part of the group that first landed in Q'ten Lo.

Volume 14
While in Q'ten Lo, Atla participated in the battle against the sealed Orochi. However, she was ineffective in this fight because she dumped the weapon that Erhard's master had created for her.

Thanks to Naofumi's training with Atla, he was starting to be able to see the life force which was essential to Hengen Musou. Encouraged by the results, they trained harder so that Naofumi would be able to implement life force for battle. S'yne taught Naofumi and Atla the defense techniques that have been forgotten in their world.

Atla's obsession with Naofumi has slowly grown into a larger problem requiring help from the whole party. Fohl was commanded to step up and take responsibility for Atla's problematic behavior.

Volume 15
Back in their village in Melromarc, Fohl takes Naofumi aside to ask him to stop bringing Atla to dangerous battles. Naofumi accepts on the condition that Fohl will be strong enough to take her place and to stop her from going in the first place. Fohl then decides to leave the village for a while to train in the Hengen Musou Style to get stronger.

Atla accompanied Naofumi when he went out to deal with Fitoria's rogue filolials problem. When they found Motoyasu leading the filolials, Atla was able to sense that he was full of love to the point of insanity. After losing a filolial race to Naofumi, Motoyasu used the skill Unleash Ressentiment. Under the influence of this skill, Atla attacked Raphtalia. With Raphtalia barely able to contain Atla's jealous attacks, Naofumi and Filo were able to convince Motoyasu to stop the skill. Atla was then knocked out and brought back to the village.

Before Fohl returned, Atla accidentally overheard about Naofumi's promise to Fohl and got greatly upset. When Fohl got back, she challenged him to a fight. The two fought intensely, arguing whether Atla should go to fight the Phoenix with the heroes. Using all of their skills and techniques, they both passed out in a draw. After their recovery, Fohl allowed Atla to participate in the battle with the Phoenix.

Before the battle of the Phoenix, Atla tried to pick up the Seven Star Gauntlets but they wouldn't respond to her. Despite Fohl's protests, Atla decides to fight it the front lines by Naofumi.

During the battle, Atla fought very well against the Phoenix. She was able to use her Hengen Musou to prevent the Phoenix's attack from hitting the troops. She was also able to place several critical hits on the Phoenix. However, when one of the two birds was close to death, a mysterious attack killed it which caused it to explode. Naofumi, despite his shield and fire resistance enhancements, was not able to hold back the explosion. Right when Naofumi was about to die from enduring the sustained explosion, Atla jumped ahead and gathered the entire explosion into herself and redirected it away from everyone.

Naofumi caught the charred Atla as she fell from the sky. Desperately, Naofumi tried everything to heal her but nothing worked. Despite that, Atla encouraged Naofumi. She was happy that she was able to die as his shield. Atla kissed Naofumi and made him promise that he would be more open to people's feelings towards him. With that, she died. After a few moments of grief, Atla's body vanished into Naofumi's shield and unlocked the Bless Series, Shield of Compassion.

Volume 16
After the Phoenix Guardian Beast was defeated, a grand funeral was held for those who died, including Atla.

Later, when Naofumi entered the world of the legendary weapons to commune with the Shield Spirit, he is shocked to see Ost and Atla. Atla assures him that she is not in pain within the shield. Both Ost and Atla speak on behalf of the Shield Spirit. They give him updates on what has been going on since he had been unconscious, offer him a reward from the Shield Spirit, and finally warn him about the enemy behind the waves. Before he leaves, Atla encourages Naofumi by saying that she is always with him and watching him through the shield. She asks him to not let her death chain him down. Naofumi then leaves the legendary weapons world and wakes up in Raphtalia's world.
