Keel/Chronology

Volume 4
During the attack on Idol Rabier, Raphtalia led Naofumi and the rest of his party down into the dungeon where she was previously held and tortured. After finding the remains of Rifana, they found Keel in poor condition. At first, Keel did not recognize Raphtalia due to her growth. Raphtalia introduced Naofumi who treated Keel's wounds.

After Idol summoned the Tyrant Dragon Rex, Keel was evacuated to safety with Van Reichnott.

Volume 6
Next time Naofumi meets Keel, she has been well-dressed and taken care of by Van Reichnott. Keel demands that Naofumi takes care of Raphtalia and wishes she could fight in the waves as well. Despite Raphtalia's desire to keep Keel safe, Naofumi invites her to his party to train.

In order to maximize Keel and Rishia's growth, he asks both of them to become slaves. Keel immediately declines due to the horrid treatment he has had as a past slave. However, despite the trauma, Keel finally decides to become a slave again in order to save her village and Raphtalia. Keel's stats are noted to be pretty low level so Naofumi asks her to go grind levels with Filo. Keel endures the grueling training and makes good progress in leveling up. With the rapid leveling up, he is also growing.

After a while of training, Naofumi takes Keel to the Old Man's weapons shop. The Old Man recommended trying out claws or jamadhars but they stick with a sword for now. Keel, along with the rest of Naofumi's party travels to Lerno Village to look into recent monster attacks. Keel was able to attack the weaker familiars. However, one of the familiars attacked Keel and infected him. Thankfully, Naofumi was able to pull out the turtle shell infecting Keel and heal him. However, Keel was unable to help with his energy being drained. He was moved to Melromarc's castle.

Volume 10
Keel was able to return home with three other slaves from the same territory. When Naofumi was able to stop by, she was training and regretted not being able to help further with the Spirit Tortoise or Other World incidents. Apparently, Keel has also been helping Eclair in trying to recruit more people into the village. When Naofumi tries to convince the three other slaves to become his own slaves, he uses Keel's growth as motivation.

During the clean up of Lurolona Village, Keel tries to keep his old, ruined house as it is. Raphtalia promises that his old home will become a communal home that he will manage while Filo knocks it down. Keel among with the other slaves are also tasked with managing the BioPlant fruit that feeds the village.

When taking a break at the beach, Naofumi, Raphtalia, and Filo confront Keel about her gender identity. While Keel believes that she is a boy, she has the body of a girl. Fortunately, the other slaves are accepting of this change. Naofumi considers allowing same-sex relationships in his party but him hinting that Keel and Raphtalia get together makes them both embarrassed and angry. In the end, Naofumi prepares two outfits for Keel - a masculine set of armor and a frilly dress for a trading outfit. Naofumi gets her to try selling medicine and she does it successfully, albeit clumsily.

During the slave hunter attack on Lurolona Village, Keel and the other slaves successfully fend off the village. Keel was able to identify the slave hunters' boss - a former Melromarc soldier which killed the adults and sold the children to slavery. Working together, Raphtalia and Keel were able to defeat the boss while many of the slave hunters were captured.

After the battle, Naofumi explained that the remaining Luroluna slaves are likely being sold at Zeltoble. Keel offers to find in the Zeltoble arena to gain freedom for the other slaves but Naofumi asks him to protect the village while he goes there himself. After the trip, Keel happily welcomes Sadeena the other Lurolona slaves back home.

Volume 11
After the Sadeena returns to the village, she teaches Keel transformation magic. Now Keel is able to transform into her therianthrope form - a Siberian Husky. Keel, among with other slaves, were also ready for a class-up so Naofumi took them to the Dragon Hourglass. Keel decided that he wanted his class-up chosen for him so he did the ceremony with Filo present. Filo's cowlick chose the class-up and all of his stats had skyrocketed.

During an attack by the Other Worlders on Naofumi and his party, S'yne was able to protect Keel.

Volume 12
After defeating the Other Worlders, S'yne used one of their accessories to translate her speech. She made the accessory look like Keel's therianthrope form which Naofumi calls Keel #2.

By this point, Naofumi trust Keel enough to leave her in charge of onboarding the new slaves but worries that she is getting too familiar with him. Unbeknownst to Naofumi, some of the slaves including Keel have taken a monster egg, registered it with Naofumi as the owner and raised it. Unhappily, Naofumi entrusts raising the extra-large caterpiland to Wyndia. Apparently, Keel had convinced Wyndia that Naofumi would eventually agree to the monster.

Keel participated in the defense of Lurolona Village against Q'ten Lo.

Volume 15
Keel continues to trade and exceed's Naofumi's expectations. As a reward, Naofumi cooks crepes for her and the rest of the village. Keel especially loved the crepes and even ate ones that she dropped on the floor.

Noafumi brings Keel along for the attack against the Phoenix spirit guardians. Keel is able to damage the phoenix and shows Naofumi that she has been getting stronger. Eventually, the Phoenix beasts were defeated.

Volume 16
After Atla's death during the Phoenix Arc, Keel pays her respects. Keel, along with the other villagers are inspired by Atla's sacrifice and vow to continue to fight the waves. They then return to the village. Naofumi, mentally unstable from Atla's death, tries to mistakenly fulfill other people's wishes for him. Keel tries to correct Naofumi's confusion but is ultimately unsuccessful. Sadeena eventually is able to help Naofumi. To cheer him up, Melty creates a new Phoenix festival where. Keel is shown to excitedly prepare for the festival. In the celebration of the new Phoenix festival, Keel ran a crepe stand and even tried to improve on Naofumi's original crepes.

During the defense against Takt's forces, Keel and the other villagers fight on the battlefield under Trash. They were noted to be very successful and completed their defense before Naofumi's group could defeat Takt. No one from the village was killed during this battle.
