One by one, Team Meteora’s bag of tricks are neutralized or absorbed by Altair, who unlike other creations, never had a backstory or any distinct story at all that she is tied to. Instead, she’s an open source character whose abilities and power are as infinite as the internet.
She is, as she says, a product of emotion, not logic, both in her sole motivation (to avenge her creator by destroying the world that rejected her), and the way the vast and ever-expanding network of creators who fuel her existence and acceptance has reached a near-relativistic scale.
This is why she can take away Hikayu’s new martial arts abilities with one strum of her rifle and even turn the tables on Sirius, her essential copy and the last remnants of Shimazaki Setsuna’s original creations, turning their secret weapon into one of her own to restore herself, complete with new outfit.
Throughout their struggles, Meteora and the Creators and Creations on their side have had to abide by certain rules, which means they were never going to be able to defeat an entity that surpasses those rules and can change them or make new ones on the fly.
Enter Chikujouin Magane and Mizushino Souta, with the last weapon against Altair, one that, if it’s ineffective like the previous ones, will result in them resigning themselves to the fact the world really will end.
A lie about a lie (in this case, the impossibility of beating Altair) turns inside out, transporting Altair and the others to the day Setsuna took her life, just as she is approaching the train platform from which she intends to jump.
This development, prepared mostly in the background by Magane and Souta, totally flips the script, as it messes with cause, effect, and reality in ways nothing else in their arsenal had been able to touch.
Will Altair find a way around this as well, her rage further fueled by her foes’ readiness to drag her dead creator ‘out of her grave’? Are hours numbered? Or will she stand down on her own, without having to be destroyed?
