Filo (フィーロ Fīro ?)(ambiguously translated as Firo) is a Filolial purchased alongside Raphtalia during the outset of the story. She develops into a Queen due to her association with the Hero of the Shield, and is a staunch ally to the hero, as the possessor of unique class-up effects. She also becomes particularly close to the Second Princess Melty.


Filo's personality has varied greatly throughout the story. Filo originally acted like any normal animal, prior to her transformation ability. She ate a lot, showed a great amount of affection toward Naofumi, and even convinced Naofumi to sleep in a stable with her because she was lonely, by pulling on his mantle. After Filo gained the ability to transform, her personality became that of a spoiled child; she would refuse orders until she was fed, would throw fits when Naofumi wouldn't sleep in the same bed as her, and would randomly transform whenever she saw fit. In an attempt to try and fix her personality Naofumi threatened to sell her (and with a little help from an advanced slave mark) Filo began to behave much more appropriately. Since that point, Filo became a trustworthy and reliable member of Naofumi's party. Filo since has worked hard to gain Naofumi's approval so that she won't be pushed aside if something should happen to her (though it is unlikely Naofumi would really ever do that and instead used it as a threat to discipline her).

Filo has also shown to be very caring, she loves Naofumi very much and considers him "her property" and often reminds Raphtalia that she "won't lose to her." She has shown great affection toward Melty, the second princess and even so went so far as being unable to defeat an enemy because she thought the enemy looked like Melty.

Though intelligent, she mostly acts like an airhead and doesn't pay much attention to anything that she has no interest in. She will often doze off when others are talking about things she has no interest in. She is attracted to shiny objects, music and loves to sing. Filo also loves to swim. She collects all the shiny objects as her treasure though they really are just trash. She enjoys singing and learns a song in every tavern they visit by watching the regular patrons, before joining them. She also sings a lullaby for the new slaves of Rock Valley village, to make them sleep comfortably.

Filo has a boundless appetite and has poor table manners which contradict her appearance. She eats everything and anything, she even once remarked that she thought that her own kind looks delicious. But, she hates alcohol and rucolu fruit. In nature she hates dragons.

Filo is way too talkative. Filo can figure out and say exactly the things people are trying to hide. Her bluntness is mostly due to her naiveness which sometimes deepens the other person's wounds. She is good with magic and quickly learns it and can also judge other beings level of skill with magic. She can see through lies, this was shown during the party exchange when she revealed to Raphtalia the actions, lies, and motives of Itsuki.

Filo is a good judge of character and is able to see through anyone, this is shown many times such as Filo refusing to let Raphtalia have Naofumi(Knowing Raphtalia's feelings for him), Nafoumi's strange thought, Motoyatsu's intention and also Itsuki's personality. It was this trait of Filo that convinced Nafoumi to trust Melty, as Filo completely trust her.

She’s been reserved as of late, but from the start, she’s been overly intrusive.


Filo's Appearance has changed many times, depending on her form.

Beast/Monster Form- When Filo was born she was a small pink chick, who looked to be about the size of an average chick. After a day, and some leveling, she had grown to the size of a steamed bun. Filo's third appearance change would be to that of a small baby ostrich, not wuite large enough to ride on, but definitely larger than the prior 2 forms. Filo would then grow into her fourth beast transformation, which was the size of a normal ostrich, and she was now capable of being ridden. It should also be noted that Filo's feathers had started to turn into a much lighter shade of pink than in her prior forms, and were beginning to turn white. Filo's last and most current form is larger than an ostrich and resembles an owl, her feathers are also almost completely white aside from a small ruffle on her abdomen and some feathers on her wings which still contain pink.


Filo has high basic attack and speed. She can also use ranged magic. Her specialty is crowd clearing. She can’t use pressure points or Hengen Musou, but she can use her natural overflowing power to subjugate her enemies. Looking at just speed, Filo is peerless. Her attacks are extremely quick and heavy. She can also accelerate herself to even greater speeds with Magic, making her a troublesome opponent. Filo is big this means when trying to dodge, she is at a disadvantage. Her battle experience and actual level are high, and she has gotten an understanding of both magic and Chi. Filo’s singing ability has reached magical levels.

Filo has experience singing in bars. Becoming quite famous by word of mouth. Filo’s definitely good at singing. If there’s music playing, she can make words and tunes to complement the song perfectly, and she’s got a nice sense of rhythm. She also likes dancing, and in human form, she’s a bishojo(beautiful young girl).


Filo was originally born from a monster egg which Naofumi purchased from the slave trader, which the trader used as a business front. Originally Filo had the appearance of a small pink Filolial chick (much like an actual chick) and would sit on top of Naofumi's head when they were on the road. However Filo grew very rapidly and within a few days was the size of a normal Filolial making such actions impossible but allowing her to grow to a size so that she could be used to pull their cart, this was thanks to Naofumi's monster tamer shield, which he unlocked from some egg shell's his shield had absorbed. Filo also has exceptionally fast legs, so much so in fact that she was able to beat a dragon in a foot race. Filo's growth, however, was not finished at that point as a day later she had grown to exceed the size of a normal Filolial and upon interrogating the slave trader, he found that she was a "Filolial Queen". Naofumi, wanting to know more about what a Filolial Queen was, offered to have the slave trader take care of Filo for a few days, but, shortly after leaving her, he was called back due to a ruckus she had caused after being separated from her master. After Naofumi and the slave trader got into an argument, a strange voice was heard from the cage Filo was in, and much to everyone's surprise, Filo transformed herself into a small human girl with blonde hair and reached out for Naofumi.




  • Iwatani Naofumi (Master)- Filo loves Naofumi very much and even when he made questionable decisions, she stood by him without even a second thought.
  • Kitamura Motoyasu- Filo hates Motoyasu very much, do to him calling her "lame" and " a fat bird".Filo kicks him the crouch every time they meet. After his female companion 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: Filo sees her as an elder sister, though she would prefer it if Filo viewed her as a motherly figure, but lets it be. The idea of being called mother is because Naofumi was raising Filo and in hopes of positioning herself as the better half of Naofumi.
  • Melty Melromarc: She is Filo's best friend. Being the same age group and Melty's interest in Filo and filolials, in general, deepened their relationship. They care for each other.
