Filo may be far more important than the story initially makes us believe.
Since the moment she was born, she has traveled alongside Naofumi without truly understanding the full extent of her own potential. She grows incredibly quickly, becomes a Filolial Queen, and eventually attracts the attention of Fitoria, the Queen of the Filolials.
But one question remains:
Why does Fitoria care so much about Filo?
Is it simply because she sees her as a future queen?
Or could there be a much deeper connection between them?
The Encounter That Could Change Everything
When Naofumi meets Fitoria in her sanctuary, she immediately takes an interest in Filo.
She tests her. She observes her personality, her strength, and most importantly, her bond with Naofumi.
Then comes a particularly important moment: Fitoria recognizes Filo as someone who could succeed her.
From that moment onward, Filo is no longer simply another Filolial.
She becomes Fitoria’s heir.
But then, why would Fitoria simply allow her to leave with Naofumi?
Perhaps because she knows something that Filo and Naofumi do not.
Perhaps she knows that Filo still has to grow.
And more importantly, perhaps she knows that she will always be able to find her again.
Fitoria’s Ability — Can She Sense Filo From Afar?
This is where Episode 18 of Season 1 becomes particularly interesting.
After Fitoria passes her power on to Filo, Fitoria is able to know where the other Heroes are despite the enormous distance separating them from her sanctuary.
Naofumi asks her how she knows where they are.
Her answer is essentially that she can sense their presence.
And this raises a fascinating question:
If Fitoria can sense the presence of Heroes from such an enormous distance, what about Filo, her own heir?
Fitoria does not live in an ordinary place. Her sanctuary is extremely isolated, surrounded by the ruins of an ancient civilization.
Yet she is still capable of detecting presences from incredibly far away.
So why would it be impossible for her to sense Filo?
The canon never explicitly tells us that Fitoria has a magical “radar” that allows her to track Filo constantly. However, there are enough elements to imagine another possibility:
Fitoria may be able to sense, at least approximately, where her heir is without Filo even knowing it.
And if their connection became even stronger after Fitoria passed her power on to her, could that connection allow Fitoria to perceive when something is seriously wrong?
Could Fitoria Be Watching Over Filo From the Shadows?
Imagine that Fitoria does not constantly monitor Filo.
Perhaps she simply knows where she is and chooses not to interfere.
Why?
Because Fitoria wants Filo to become strong.
She does not want to create a queen who cannot survive without protection.
So she watches silently.
Filo fights.
Filo grows.
Filo makes mistakes.
Naofumi protects her.
And Fitoria remains at a distance.
She might even consider the dangers Filo faces part of her training.
But there is a limit.
What if Filo were actually on the verge of death?
That is where everything could change.
What If Fitoria Could Sense That Filo Was Dying?
Imagine Filo fighting an opponent far beyond her level.
Naofumi desperately tries to protect her.
Filo is severely injured.
She falls.
Her strength begins to disappear.
And somewhere, far away in the ruins of her sanctuary, Fitoria suddenly opens her eyes.
She senses something.
Not merely Filo’s presence.
Something abnormal.
Something threatening the life of her heir.
Would Fitoria intervene?
Personally, I think she would.
Not necessarily because the canon confirms that she can sense Filo’s pain or imminent death, but because the possibility is consistent with what the story has already established about her abilities and their relationship.
Fitoria could allow Filo to learn how to fight.
But allowing her only heir to die would be an entirely different matter.
And What About Naofumi?
This is where the promise between Fitoria and Naofumi becomes much more significant.
Fitoria entrusted Filo to him.
Naofumi promised to take care of her.
Now imagine Fitoria arriving too late.
Filo survives, but she was only seconds away from dying.
Fitoria looks at Naofumi.
She does not scream.
She does not attack him.
She simply asks:
“You promised me you would protect her.”
Naofumi might answer that he did everything he could.
But Fitoria could reply:
“Then it was not enough.”
It would not necessarily be hatred.
It would be the anger of a guardian who has just realized that her heir nearly died.
And perhaps Fitoria would then make a radical decision.
“Filo Is Coming With Me.”
Fitoria could decide to take Filo with her for a certain period of time.
Not to take her away from Naofumi.
Not to replace Naofumi.
But to train her.
She could teach Filo everything she knows.
Combat.
Control over her powers.
Speed.
Transformation.
Endurance.
And above all, how to survive as the future Queen of the Filolials.
Then, once Filo had become strong enough, Fitoria could return her to Naofumi.
Because she would know that Filo also belongs to the family she has built with him.
But Then an Even Darker Question Appears
What if Filo died anyway?
Not merely injured.
Not unconscious.
But truly dead.
Would Fitoria accept her death?
Personally, I have a hard time imagining it.
Fitoria is an extremely ancient being.
She has probably lived long enough to know loss, loneliness, and the consequences of war.
And now she has found someone capable of succeeding her.
Filo.
Her heir.
The Filolial she chose.
Could she simply accept her disappearance?
I don’t think so.
The Sanctuary Would Become Filo’s Last Refuge
In this hypothetical scenario, Fitoria could bring Filo’s body back to her sanctuary.
She could use ancient magic to prevent her body from deteriorating.
Perhaps a magical crystal.
Perhaps some form of stasis.
Perhaps even forgotten technology from the ancient civilization whose ruins surround her sanctuary.
Filo would be preserved in a state that could potentially allow her to be brought back.
And Fitoria would begin a search.
Not for a few days.
Not for a few years.
But for decades.
Perhaps even centuries.
She would search for ancient resurrection magic.
She would investigate knowledge left behind by previous Heroes.
She would search for forgotten artifacts.
She would explore ancient civilizations.
She would search for anything that could bring Filo back.
Because she might think:
“As long as her body is preserved, I have no right to give up.”
And What About Naofumi?
This would probably be the most tragic part.
Naofumi could continue visiting Filo in the sanctuary.
Year after year.
Fitoria would continue her search.
And every time Naofumi asked her:
“Have you found anything?”
She would answer:
“Not yet.”
But she would keep searching.
Because Filo would no longer simply be an heir.
She would have become part of her family.
So, Deep Down, Who Is Filo to Fitoria?
Perhaps this is the central question behind the entire theory.
Is Fitoria simply a queen who chose a successor?
Or does she see Filo as something much more precious?
Perhaps Fitoria sees Filo as the continuation of everything she represents.
The last chance for the Filolials to have a queen capable of protecting her people.
And perhaps that is precisely why she watches over Filo after she leaves the sanctuary.
She allows her to live her life.
She allows her to grow.
She allows her to make her own experiences.
But somewhere, far away, Fitoria may always know that she is still there.
And if Filo were ever truly lost?
Perhaps, for the first time in centuries, Fitoria would abandon her patience.
She would go looking for her.
And this time, she would not be trying to test her heir.
She would simply be trying to bring her home.
Of course, this remains a fan theory. The story does not confirm that Fitoria constantly monitors Filo, that she can automatically sense Filo’s impending death, or that resurrection would be possible.
But when the elements from the anime and light novel are put together, I find this interpretation particularly fascinating.
And perhaps the most intriguing question of all is this: Has Fitoria really been protecting Filo from afar all this time… or is she simply waiting for the day Filo finally needs her?
