Myu/Chronology

History
Myu's father died before she was born.

One day, while Myu had been swimming, she gotten separated from her mother Remia and had ended up being captured by humans of the criminal gang Freidhof. She then got taken to Fuhren to be sold as a slave. However, she managed to escape into the sewer and got saved by Hajime and Shea. The two of them cleaned and fed Myu and Hajime even bought her some clothes. After learning from Myu on how she ended up in the sewers, Hajime decided to take her to Fuhren's city guards so that they may take her back home. Shea wanted to bring Myu with them on their journey, but Hajime argued that it was too dangerous to bring Myu with them and that taking her would be tantamount to kidnapping. Hajime told Myu about their plan, but she adamantly opposed and declared her desire to go with him instead. Hajime decided it was pointless to try and reason with Myu and forcefully carried her on his shoulders while taking her to Fuhren's guards. Myu tried everything she could to stay with Hajime, such as scratching his face, pulling his hair, and stealing his eyepatch, but it was all in vain as Hajime dropped her off with the guards. Myu tearfully asked if Hajime hated her since he didn't want her to be with him, but Hajime merely left her in the guards care and walked away with Shea. As Hajime and Shea left, soon after the guards building was suddenly attacked and Myu got captured again. Because of this Hajime and his companions began to attack all of Freidhof's bases in Fuhren until they learned of Myu's location after Shea beat it out of Freidhof's leader Hansen, just before killing him. Hajime and Yue arrived at an underground prison that was underneath an art museum and rescued several enslaved children before proceeding to rescue Myu. Myu was held in a water-filled tank and shackled while she was about to be sold off. She missed Hajime very much and was so scared that the auctioneer threatened to beat her with his cane if she did not perform for the bidders, but before he could hit her, however, he was killed when Hajime landed on top of him before freeing Myu. At first, Myu was shocked to see Hajime again, but immediately cried for joy and hugged him. Hajime killed all of the guards at the auction while having Myu cover her eyes and ears so as not to scare her. He then jumped out and had Myu open her eyes after he was standing mid-air, much to her surprise. Hajime finished up by blowing up the entire auction house, while demonstrating to Myu the concept of "fireworks", much to her shock. Hajime and Myu met up with Yue after witnessing her destroy Freidhof's remaining bases with her spell "Draconic Thunder". Myu was wary of Yue at first, but after Yue had been taken in by her cuteness and kindly praised her for enduring all of her hardships while being kidnapped, Myu warmed up to Yue while crying in her arms for all the suffering she faced.

Hajime took Myu to the Fuhren's Adventurer's Guild in order to appraise branch chief Ilwa Chang of the situation. Ilwa gave Hajime the choice of either letting Fuhren's officials take Myu back home, or to let him do it. Hajime decided to personally take Myu home after she and Shea begged him to let her accompany them. As Myu expressed her joy that she would get to be with Hajime, he asked her to stop referring him as "Onii-chan", as she had been doing since they first met. To his surprise, Myu decided to call him "Papa" instead since she did not have a father. Hajime tried to convince her to change her mind, but Myu liked calling Hajime by his new name and would always cry whenever he tried to talk her out of using it.

Hajime, Myu, and the others made their way to Horaud Town in order to deliver a letter from Ilwa to the adventurer guild's Horaud branch chief. As they were traveling using Hajime's vehicle Brise, Shea wanted to drive using Hajime's motorcycle Stieff. Watching Shea perform amazing stunts while driving prompted Myu to want to drive it as well, but Hajime instantly rejected her request. Myu was upset and began to throw a tantrum while sitting on top of Yue's lap, but Hajime calmed her down by promising her that she could ride it later with him if she behaved. When they arrived at Horaud, Hajime carried Myu on his shoulders while they headed for the guild. Hajime's expression changed as he was walking along Horaud's streets and began to remember about the first time he visited the town, which ended up with him falling to the bottom of the Great Orcus Labyrinth. Hajime's change in expression caught Myu's attention and asked what was wrong, to which Hajime told her that he was just remembering his first time in Horaud. When they finally arrived at Horaud's Adventurer's Guild, they were met with hostile glares from all the adventurers that were inside. This greatly scared Myu and she tried to hide herself away. Hajime comforted Myu and threatened the other adventurers to smile in order to make her feel better. This initially failed, as Myu was still scared after glancing at the adventurers, but soon came around after Yue briefly spoke to her. Hajime had the receptionist summon the branch chief in order to deliver the letter. As they were waiting, Hajime was surprised to see his classmate Kousuke Endou burst out into the hall and started shouting his name. Once he finally found Hajime, Kousuke begged him to come back to the labyrinth in order to save their classmates from a demon that had ambushed them. Hajime was taken aback by Kousuke's hysterical attitude, but was soon escorted away by branch chief Loa Bawavis in order to discuss the situation in private. As Kousuke was explaining the situation, Myu was eating snacks that Hajime gave her so that she would not be scared by what was happening. Seeing the young girl act completely indifferent to the life and death situation that was taking place prompted Kousuke to lash out at her. This scared Myu and she began crying in Hajime's arms. Hajime comforted her while threatening to kill Kousuke for taking out his anger on his "daughter". After Kousuke finished his story and begged Hajime to help their classmates, Hajime was hesitant at first, but ultimately decided to go after his companions, including Myu, offered to support whatever discussion he would make. Hajime had Myu stay behind at the guild while he went off to save his classmates, much to her displeasure, due to it being too dangerous to bring a young girl with him, and also had Tio stay behind to watch over her.

After Hajime successfully rescued his classmate and left the labyrinth, he was instantly greeted by Myu as she ran up to hug him. Everyone was taken by surprise after she called Hajime her father. Tio arrived soon after and explained how she stopped a criminal from attempting to kidnap Myu and did it in a way that the young girl could not see. Several of the the kidnapper's acquaintances appeared soon after in order to get revenge for what Tio did to their associate, but they were all mercilessly taken care of by Hajime. Myu and the others left soon after with Hajime, who was also now accompanied by Kaori after expressing her desire to be with him.

Myu continued to travel with Hajime and the others as they visited several more towns while heading to the Grand Gruen Volcano for the next labyrinth. Among their travels, they visited a town that was famous for its textiles and got new clothes for everyone, and they even trained using Hajime's weapons for target practice (to which Myu displayed an incredible aptitude for using fire arms). As they were traveling across the Grand Gruen Desert, they came across Bize Feuward Zengen of the Dukedom of Ankaji, who was severely ill and surrounded by giant carnivorous sand worms. After he was partially healed by Kaori, Bize told them about a plague that had spread throughout his homeland and that he attempted to warm the Heiligh Kingdom and request for their aid before he began showing the symptoms as well. Hajime decided to help Bize and his people since he planned to leave Myu in Ankaji while he would explore the labyrinth in the Gruen Volcano. Hajime discovered the source of the plague to be from their oasis and managed to create a temporary source of water for Ankaji until it could be properly purified. Hajime said goodbye to Myu and Kaori as the latter stayed behind in order to heal as many people as possible. Myu was sad that she would be separated from Hajime for a while, but she would obey his wishes and stay behind. She asked him for a goodbye kiss before he left, to which Hajime gave her on the cheek after Myu began to cry. While Hajime and the others were exploring the labyrinth, Myu was under the care of Bize's younger sister Ailee, who had grown quite fond of the young dagon and treated her like a sister. After a while, Tio returned alone and explained how Hajime and the others had been trapped in the volcano after they were ambushed by the demon Freid Bagwa, who also caused it to erupt with them still inside. Myu started crying when she learned Hajime still hadn’t returned, but Tio calmed her down by telling her that Hajime’s daughter had to be a strong girl and strong girls didn’t cry. Myu and Kaori spent the next two days in Ankaji while Tio attempted to locate Hajime around the now erupting volcano. Myu continued to be supervised by Ailee while Tio and Kaori were busy. Although she had faith that Hajime would return, Myu couldn't hide her sadness from being apart from him. Ailee was impressed with how brave Myu was behaving and was interested in the story of how she met Hajime, to which Myu was happy to tell. Unfortunately, the way Myu told her story caused Ailee to have a lot of misguided ill will towards Hajime, and believed him to be a monster that prayed on children.

After Tio's unsuccessful efforts to find Hajime, and Kaori finally finished healing as many people as she could, the two of them decided to take Myu back to her mother in Erisen, then return back to resume their search for Hajime. Myu was sad that she would not get to see Hajime, but was also very eager to be reunited with her mother, and the three of them traveled using Tio's dragon form. After Myu arrived at Erisen, Tio told Myu that she could see Hajime and the others, much to their surprise. Hearing this greatly excited Myu and she immediately jumped off of Tio's back and began to freefall towards him. Hajime heard Myu's voice, and in a panic, jumped mid-air and safely caught her. Hajime then scolded Myu for acting so reckless, which caused Myu to cry. After having Myu promise to never behave that reckless again, Hajime comforted her while giving her a hug, much to Myu's delight. Hajime and the others finally managed to bring Myu to her mother Remia. Myu heard her mother's voice and instantly ran up to greet her. Remia warmingly embraced her daughter after being separated for over four months and repeatedly apologized to Myu. Much to Remia's surprise, Myu tried to comfort her mother and told that she was back now. After the two of them hugged, Myu was shocked to see the injuries on Remia's legs and asked Hajime to help her, while calling him her father. Hearing Myu use that term on Hajime shocked Remia and was taken by Hajime to carried her back into her home to have her healed. After learning about how Hajime saved Myu, Remia expressed her gratitude and promised to pay him back no matter what. She offered to let Hajime and the others stay at her home until they were ready to visit the next labyrinth at the Sunken Ruins of Melusine. After five days at Myu's home, Hajime and the others left her while they explored the labyrinth. They managed to successfully clear it and decided to spend some more time with Myu before leaving her for good. After six days of resting, Remia could see that Hajime was wavering to resume his journey since that would mean saying goodbye to Myu for good. She told him not to worry about her and the he should focus on finishing his objective, to which Hajime accepted. That night, Hajime told Myu that he was leaving the next day. She was very sad about it, but did her best not to cry. Myu asked Hajime if she would ever see him again, but he did not answer her. Myu then declared that she would come and find him once she was older and that she could go wherever Hajime goes, regardless of the danger, since she was his daughter. Hearing Myu's resolve caused Hajime to make a decision and told Myu that he would see her again once his journey was over, and that he would even show her his homeworld, to which Myu was eager to see and gave him a hug. Myu and Remia said goodbye to Hajime the next day.

When Myu was swimming out on the ocean one day, she encountered the fishman Riiman after he sensed the magic from her pendent that Hajime gave her. Among other abilities, it gave Myu the power of telepathy. At first Myu was scared of Riiman, but calmed down after learning that he was a friend of Hajime. After learning that Myu was Hajime's daughter, Riiman vowed to help her if she was ever in trouble and also advised her on the type of wife that Hajime should be with. Just then Riiman's wife appeared and dragged him down to the bottom of the ocean while complaining to him about not spending enough time with her or his children. When Myu returned home, she asked her mother about the type of wife she would be if she married Hajime. Hearing her daughter ask such questions and using more mature terms caused Remia to snap and asked Myu who taught her those questions, to which Remia understood what Riiman meant when warning her about that type of wife that Hajime should end up with.
