Filo/Relationships

Naofumi Iwatani
Filo is Naofumi's second-closest companion after Raphtalia. The moment Filo hatched from her egg, she immediately became attached to Naofumi through imprinting. When Naofumi continued to raise Filo, her feelings for him grew even stronger to the point that Filo loves Naofumi very much that even when he made questionable decisions, she stood by him without even a second thought. It is through this, that they both share their respective dislike towards Motoyasu. Filo even has a desire to be Naofumi's mate. Her attachment also makes Filo worry that Naofumi might leave her. Despite Filo's love for her master, Naofumi sees himself more as Filo's owner.

Regardless, Filo becomes very invaluable to Naofumi, that she is considered as important (if not right after) as Raphtalia. While Naofumi considers himself more of an owner to Filo, he treats Filo more like his own daughter. This treatment is similar to how he cared for Raphtalia when she still looked like a child. Filo is the second one to help Naofumi not be consumed by his cursed series, the Shield of Wrath.

Motoyasu Kitamura
Filo hates Motoyasu very much, due to him calling her "lame" and "a fat bird." Filo kicks him the crotch every time they meet. After his female companions betrayed Motoyasu, he has been trying to seek Filo's love much to the latter's trauma, causing her to run away from him.

Raphtalia
When Filo first hatched from an egg Naofumi bought, Raphtalia was rather neutral towards Filo. However, when Naofumi started to give Filo special attention, Raphtalia started to become jealous of her. These feelings grew even further after Filo took on her human appearance and whenever Naofumi compliments Filo for her appearance and actions. In return, Filo also sees Raphtalia as a rival for Naofumi's affections, where she even states how she won't hand him over to Raphtalia, much to her chagrin. Whenever Raphtalia tries to share a moment with Naofumi, Filo would often (or want to) interrupt in order to not be left out.

However, they also develop a healthy relationship where Filo sees Raphtalia as an elder sister, though Raphtalia prefers to be seen more as a mother figure to better position herself with Naofumi who raised Filo. Raphtalia sometimes worries that Filo might pick up some of Naofumi's bad behaviors. In addition, their care for each other extends to working well together and perform combo skills in battles to protect Naofumi who in turn, protects them. It through these various battles that it shows how they both displayed visible concerns for each other.

Fitoria
Fitoria sees Filo as her potential successor. While Filo is willing to get along with her fellow Filolial Queen, she will go against Fitoria when Fitoria tested Filo by almost taking Naofumi's life. It is through this test that Fitoria is willing to trust Naofumi and that she blessed Filo to being the next Filolial Queen for passing her test. This connection not only made Filo stronger but also allows the two to communicate with each other. Fitoria also expects much from Filo, which includes watching over Naofumi.

Melty Q Melromarc
She is Filo's best friend. Through their initial interactions, they became fast friends. Being in the same age group and Melty's interest in Filo and Filolials, in general, deepened their relationship. Filo was saddened by how Naofumi originally told her to no longer hang out with Melty.

When Melty ends up traveling with Naofumi because the Three Churches and Malty framing Naofumi, Filo expressed joy in travel with Melty again. It through this journey that they became even closer and care for each other's well being. This was first proven when Melty attacks Motoyasu for holding Filo hostage when Filo was unable to transform. Filo's trust in Melty became deep that she is willing to listen and believe what Melty asks or says. An example is how Filo believed and listen to Melty into playing a game of hide and seek when Melty was actually protecting Filo and her comrades by giving herself up to Idol Rabier, a corrupted noble who was looking for them. This also resulted in Filo wanted to rescue Melty. Their bonds is strong enough they're able to do a combo skill together.

When Naofumi's name was cleared up and his relationship with Melty improved, Filo was allowed to hang out with Melty again. This proceeded in Filo often hanging out with Melty whenever Naofumi had something else to do. They would often sleep together such as sharing the same bed or Melty resting, preferably naked, in Filo's feather. When Filo has the effect of her heat season enhanced by Motoyasu's Lust Series, Naofumi traps Melty with Filo in hopes of Melty calming Filo's lust (which she does).

Rishia
While the two aren't often shown interacting, the became close as fellow party members. When they reunite after being separated in another world, Rishia showed her concern and care for Filo when the later was being held captive for display.
