Ryuto, who was at a loss for words, decided to ignore it altogether.

"In any case, you are their ally. There's no denying that. However, for them, you are not their ally. In fact, they are not even aware of your existence."

"Oh, how do you figure?"

"If you were truly allies, there would be no need to use them. Though one could argue it was a ploy, the truth is they willingly became stepping stones for your plans. If they knew you, there would have been no need for such sacrifices. Although terrorists are known for their willingness to sacrifice themselves, ultimately, there was no need to make the ruse so convincing."

"So what you're saying is that they weren't acting, but... this is all speculation, right? Or do you have evidence, boy?"

I suppose there's no evidence to confirm it. Fiona's smile was filled with confidence.

Well, in reality...

"To be honest, I have no evidence."

Ryuto indeed had no evidence.

Upon seeing his speculation proven correct, Fiona's smile turned into a joyful one.

"So, is boy prepared to admit that he was wrong?"

"No, I have no intention of doing so."

"Sigh..."

Fiona's smile froze unintentionally.

"Well, although there's no evidence, I still believe that way. If I have to explain why, it's because at least from my perspective, it didn't seem like an act."

"...Even without evidence, you refuse to admit you were wrong. Is that really a good thing, boy? Saying things without any basis."

Tsk... He just doesn't want to admit defeat, simply doesn't want to acknowledge his mistake, just arrogantly showing off.

Although Fiona thought so, she denied that conclusion upon seeing Ryuto's gaze.

That gaze told her that things were not as she had imagined. Though it had no basis, she had an inexplicable feeling, similar to that time...

Seemingly to erase that thought, Fiona smiled faintly.

"It's quite strange, isn't it?"

"What do you mean?"

"Boy actually believes these baseless words, only visible to himself. This makes it even more unreliable, especially for boy."

"What do you mean?"

"At least in the eyes of big sister here, boy is someone incredibly, no, terrifyingly rational. A true monster of rationality. For such a rational boy to say something so irrational, no matter how you look at it, it's very strange."

"Are you mocking me?"

Ryuto semi-opened his eyes and retorted.

"No, it's praise. Boy probably doesn't know, but big sister rarely praises people."

"Even if you say that, I don't feel like it's a compliment..."

"Well, let's put that aside for now. Let's assume it's just as you theorized."

"What do you mean by 'even if...'?"

"So, boy, what do you want to say next?"

"I just want to say that you simply used their strategy against them. Since they don't know you are their ally, they surely would impede your plans. So you decided to use others to eliminate them and create opportunities for yourself."

At this moment, Fios smirked with a hint of pride.

"Boy, your words are a bit contradictory. If I am their ally, then there's no need to hide the truth from them. That way, they won't hinder me, big sister, anymore. After all, our goal is to hijack the plane. Since we share the same goal, that makes us comrades, right?"

However, Ryuto's gaze remained as sharp as a blade.

"Although what you said is not wrong, it is not contradictory because you have your reasons for not telling them."
