Fitoria/Chronology

Volume 3
Once paroling human grounds in her disguise, she came across Melty who was thrilled to see a new variant of Filolial and offered her jerky. Fitoria ignored her and ran away. But, Melty used her carriage to chase after her. Soon it becomes a game of tag. Fitoria saw her caring nature towards Filolia and was impressed. They ended up in a dragon area, where Melty put herself to save the filolial which pulled her carriage. Fitoria appeared and defeated the dragon and saved Melty and her Filolial.

Fitoria healed Melty and her Filolial. Later, she let Melty play with her herd before sending her with few of her subordinate to the human town where she ends up with Naofumi. Her subordinates spotted Filo and informed Fitoria about the new Filolial queen. Fitoria went to find if the new queen is worthy of the title.

Volume 4
Fitoria and her army of Filolials locate Naofumi's group and save them from the sealed ancient monster Tyrant Dragon Rex. Fitoria is able to strike down the T-rex demon in a single blow, stunning Naofumi's team with her legendary strength. Naofumi uses the dead T-rex to upgrade his shield powers, but Fitoria warns him that one day he will not be able to control the dark powers of a cursed shield (Rage Shield).

Fitoria brings Naofumi's team back to her home-camp, a site of ancient ruins. At night, she questions Naofumi about why during the Wave of Catastrophe the Four Heroes were absent from the rest of the globe. This is the first time Naofumi learns that each hero was supposed to be summoned to different countries, not just Melromarc.

Fitoria also demands Naofumi to mend his relationship with the other three heroes and work together. Naofumi refuses, saying that it is impossible to work with them after how much they have betrayed and backstabbed Naofumi. Fitoria then threatens to kill the four heroes if they do not work together, saying that after they die, the world will summon four new heroes, which she claims will benefit the world in the long run.

After Naofumi still refuses to work with the other heroes, Fitoria forces a duel with Filo by taking Melty as a hostage. If Filo loses, Fitoria threatens to kill all the heroes, and if Filo proves her strength, Fitoria says she will release Melty and not kill the heroes for 'a while'.

During the duel, Naofumi tells Filo not to give up and stay strong. That reminds Fitoria how her former hero raised her. Indeed, although Filo is outmatched by Fitoria, Filo continues to fight and attack, once even breaking Fitoria's magic shield with a spiral strike, shocking everybody.

After the duel, Fitoria is satisfied with Filo's ability and determination. Fitoria then chooses Filo as her successor, saying that the duel was a trial. Fitoria gives Filo a tiara and cowlick to symbolize Filo's new queen status. She also unlocks all of Naofumi's Filolial Shield Series. The gang celebrates the anointment of a new queen.

At night, Fitoria again pleads Naofumi to mend his relationship with the heroes. She says the future waves will be much stronger and that the heroes will die soon if they do not work together (as they are still too weak alone). She asks Naofumi specifically because she rates him higher than the other heroes, especially because Naofumi helped raise Filo, the new Filolia queen. She encourages Naofumi to go back and clear his name, saying that if he does not tell the other heroes they are wrong, that would be a tacit admission of guilt.

She also says that in the future, there will be a big calamity wave that will require great sacrifice. The heroes will have to choose whether to save the world or the people. She has experienced such a moment before with her old hero but says she does not remember much. While most heroes choose to save the people, they all failed.

In the end, Naofumi agrees and says he will try his best to mend ties with the other heroes. This reminds Fitoria of her former hero, and she then lies her head on Naofumi's lap. She casts a spell on Naofumi's shield to slow down its corrosion due to the effects of the Rage Shield. Naofumi then asks if her former hero was the Shield Hero. Fitoria answers him that she forgets as Filolials have short memories and that she also outlived her time by centuries. But, it is heavily implied that her former master may be a Shield Hero.

Volume 5
When Naofumi tries to conduct a class-up ceremony, the cowlick Fitoria had given Filo interferes. It forces Filo and Raphtalia to take a special (albeit more powerful) class-up path.

Volume 7
After Naofumi's party had beheaded the Spirit Tortoise's head, it transformed into a terrifying, more powerful form and headed straight for Melromarc. Naofumi and his party tried to stop the Guardian Beast, but it quickly became clear that they were not strong enough. However, Fitoria ran as fast as she could towards the Spirit Tortoise and Naofumi's party was able to delay it just enough so it didn't destroy Castle Town before she arrived.

As Fitoria fought the Spirit Tortoise, it seemed to be in a stalemate - Fitoria's incredible power verses the Spirit Tortoise's unending regeneration. However, knowing that this wouldn't last forever, Naofumi and Queen Mirellia organized an invasion party to travel inside the Spirit Tortoise. With coordination with Fitoria, they were able to destroy the head(s) and heart at the same time which revealed the pathway to the Spirit Tortoise's core. The Heroes confronted Kyo who was behind the Spirit Tortoise's rampage and destroyed the core which permanently killed the Spirit Tortoise. However, it is only thanks to Fitoria that the beast was prevented from completely destroying Melromarc.

Volume 13
While Melty and Filo were power-leveling, Fitoria had tasked them to get Naofumi's help for an unknown problem. As advance payment, she had bestowed several blessings on Melty and Filo which greatly increased their stats. However, Naofumi brushed off the request for help - saying that he'll deal with it after he deals with Q'ten Lo.

Volume 15
After being asked by Queen Mirellia, Melty and Fitoria, Naofumi finally looks into the filolial issue he was tasked with a while ago. Apparently some filolials have gone renegade, going against her authority and are even stealing wagons across the world. These renegade filolials have grown to have some kind of "turf war" with Fitoria's filolials.

When Naofumi looks into the source of the issue, he finds Motoyasu. Apparently Motoyasu, in his Filo-obsessed state, has been raising and hatching as many filolials as he can which have slowly gone out of control. However, after Naofumi beats Motoyasu in a race and Filo talks him into surrendering, the filolial problem is resolved.

Volume 20
When Naofumi returns from his second trip to Glass' World, he contacts Fitoria to exchange information. Fitoria then invites Naofumi to her sanctuary. Within Fitoria's nest, the four Legendary Heroes find powerful weapons which they use to enhance their own - including a spear called the Dragon Clock Hand for Motoyasu. They also find the red poison which unlocks the 0 series weapons. They also find a mural which depicts the history and truth behind the waves but Fitoria's unreliable memory provides very little help explaining the lore to Naofumi.
