Fitoria/Relationships

Naofumi Iwatani
Due to Naofumi raising a worthy Filolial Queen, she believes that Naofumi can't be a bad person. Though Filo passing the test showed that she could trust Naofumi, Fitoria wanted the Heroes to cooperate and feels that Naofumi alone can achieve it. Fitoria understands Naofumi's situation of being discriminated and persecuted by the human supremacist nation for religious reasons. She also senses his sorrow and anger, all which made him unlock the Curse Series. Still, she pressures him to do what is necessary and was prepared to dirty her hands if he refuses to do his duty. She discards all of Naofumi's reasons and forces him to comply.

Naofumi sympathizes with Fitoria for fighting the Waves of Calamity alone for a long time and being constantly disappointed, let down by the people and the Heroes. Naofumi suspects that Fitoria might have been worshiped in the past and attempts may have been made to do away with her, for humans are a fragile creature who either worship, control, or destroy the unknown power which is beyond their grasp. Despite all her disappointments and betrayals, she still fought and survived to keep her promise to her master. Realizing all this, Naofumi felt that fulfilling her request was the least he could do for her.

It was because of Fitoria's word that Naofumi decided to give another try in mending his relations with the Heroes and to stay in Melromarc, as they prefer to stay there. While Fitoria can't remember well, she has also seen similarities between Naofumi and the past Hero who raised her. Fitoria sees her previous master in Naofumi while Naofumi sees Filo in her and wonders if Filo may end up like her after he leaves the world.

Filo
When Fitoria learns of Filo's existence, she becomes interested in Filo as a candidate to be her successor as the new Queen of Filolials. Upon meeting Filo, they soon got along that they appear to be sisters. When Fitoria sees how well Filo is raised, she immediately trusts Filo as someone worthy to succeed her. It is because of Filo that Fitoria also came to trust Filo's comrades. Filo finds Fitoria's power and size to be amazing and wonders (and desires) if she can be like her.

However, Filo is willing to fight Fitoria when the latter starts to show hostility by imprisoning Melty to have Naofumi comply with her demands and requesting a duel with Filo. When the duel was revealed to be a trial and Filo passes, Fitoria officially appoints Filo as her successor and the two got along again. Through this connection, Filo (along with those near her) can communicate with Fitoria.

Melty Q Melromarc
Before their encounter, Melty knew the legends surrounding Fitoria as the Queen of Filolials. Once, Melty ran into Fitoria in her disguise as a normal filolial and tried to befriend her, not knowing who she was. Like with Filo, Melty is both shocked and enthralled when she meets and sees Fitoria's humongous appearance for the first time. While the two were temporarily at odds when Fitoria took Melty as a hostage, they soon made up when Fitoria revealed her true intentions that it was all a trial for Filo who passed.

In the anime, Fitoria goes as far as letting Melty ride her as an apology.

Raph-chan
Raph-chan feels that Fitoria is manipulating Naofumi to do her bidding; Fitoria does accept the fact that her method may be flawed but not her motives. Raph-chan argues that Naofumi would still help if asked directly rather than twisting her words.
