In this world, humans cannot touch mysterious powers; only non-humans can possess them. Therefore, Tohsaka Rin's power as a human was suppressed within her inner human world and could not be unleashed.
Heroic Spirits are essentially born from human fantasies and legends, transcending the human plane to reach the level of star spirits, existing between human and non-human.
When Tohsaka Rin first arrived in this world, the Heroic Spirit core in her soul sea was also suppressed by the world and could not be activated. However, when Tohsaka Rin obtained the Imperial Arm key of the demons extract, she discovered that this infinite Imperial Arm, capable of evolving to adapt to all external factors, could actually serve as a non-human output for her Heroic Spirit core!
By bringing the power of the Heroic Spirit into the demons extract and then attaching it to herself, the knight of the lake, who vowed to eternally protect his princess, descended upon this otherworldly realm!
"demons extract: knight of the lake!!!"
Boom!!!
A pitch-Black energy storm erupted from beneath Tohsaka Rin's feet! Roaring gales swept across the entire training ground, nearly blowing the students in the front row to the back. The upper half of a ferocious dragon-shaped Danger Beast, five meters tall, burst forth from the ground behind Tohsaka Rin! That was the prototype of the demons extract, the Super Danger Beast, Tyrande, the Dragon of Infinite Evolution! Whenever the demons extract was activated for the first time by a new operator, it would appear, completely destroying the armor's previous form, which was molded for the last user, and reassembling it according to the new user's physique.
"Roar—!!!"
The more compatible the user of the demons extract was with the Imperial Arm, the higher the activation level of the Imperial Arm's material. At this moment, the demons extract, activated by Tohsaka Rin, had a living dragon beast that seemed ready to break free from the Imperial Arm's restraints! A soul-stirring dragon's roar pierced the clouds!
"That is... the 'demon possession - operating armor,' the prototype template for all armored Imperial Arms, lost for four hundred years?"
"I can't believe this woman was hiding such a trump card?"
"No, that's not right! According to Imperial historical records, the demons extract only shows signs of the Danger Beast reviving during its initial activation and during armor evolution. She's clearly using it for the first time!"
"To hell with 'first time'! This aura and scene are so much grander than when Senior Budo activated his Imperial Arm. That dragon clearly looks like it's about to burst out of the Imperial Arm!"
"Long live Lady Tohsaka Rin!!!"
Just as the astonished students, disregarding discipline, began to clamor uncontrollably, Tyrande, revived from the Imperial Arm, seemed about to break free from its restraints. As it lunged from behind Tohsaka Rin, poised to capture and kill her, a dark shadow suddenly appeared above the dragon beast, a tall, pitch-Black figure resembling a descending demon god!
"Wuwuwuwu Ahahahahah----"
Ferocious, soul-stirring glints of blood-red light emanated from the V-shape on its helmet! The suddenly appearing shadow of the demon god clamped one hand around the head of the Imperial Arm's dragon, which was on the verge of losing control and rampaging due to excessive activation. Infinite immense power suppressed the dragon beast that was about to erupt. Subsequently, the pitch-Black, ferocious armored demon god gradually merged with the roaring dragon beast, and a dark, gleaming demon knight armor attached itself to the dragon beast's surface. Finally, the pitch-Black armored dragon beast transformed into a dazzling array of light and shadow, becoming a suit of armor that armed Tohsaka Rin!
Tohsaka Rin, unexpectedly, produced a lost Imperial Arm, completely turning the tide. Instantly, the atmosphere of the entire venue erupted into chaotic excitement. Some male students were astonished, some dumbfounded; while the female military officer cadets were, without exception, thrilled, delighted beyond measure!
It was a perfect armor, neither ornate nor crude, yet it masterfully combined combat functionality with exquisite beauty. One could see the craftsman's utmost effort and meticulous design and casting. The terrifying, protruding spikes mimicking a dragon's body structure, and its construction perfectly fitting Rin's figure, formed a flawless harmony. It became an adornment showcasing her illustrious battle achievements, adding a valiant demeanor. It was the ideal armament that all soldiers going to war would involuntarily envy. The knight of the lake, descends!
"Ah ha ha ha ha...! Perfect, absolutely perfect! I truly came at the right time today! I never imagined I'd get to see such a good show!"
The chief instructor of the Assassination Squad was laughing so hard he was bending over backward, while beside him, General Black's face was so dark it looked like it would drip water, with a faint greenish tint seemingly beneath his skin.
"Is that... demon possession - operating armor? But the Imperial Armament described in the texts shouldn't look like this after activation. It should be primarily white. This current appearance is more similar to Shura's Descent: Noble Chariot. And what did she just shout... knight of the lake? Is there an Imperial Armament called knight of the lake among the forty-eight Imperial Armaments?"
A general sitting on the other side of the chief assassination instructor looked at Rin, who was encased in exquisite yet domineering Black armor, and muttered to himself in surprise. The assassination instructor, who overheard him, was undoubtedly a staunch supporter of Rin, and immediately responded with a hint of disdain:
"To think that way only means your intelligence is too crude. The records concerning demons extract in the Imperial Armament Archives state that this armor is one of the most potential-filled among the forty-eight Imperial Armaments. It can infinitely evolve and change according to the user's will and characteristics, in conjunction with its compatibility with the demons extract. The stronger the user's ability and the higher their compatibility with the Imperial Armament, the greater the difference in its displayed form from its basic appearance. Theoretically, it is an Imperial Armament that can manifest in any form!"
The chief assassination instructor's single eye sparkled with immense appreciation as he looked at Rin's figure.
"This child's compatibility with this Imperial Armament surpasses any previously known record. With her own potential, she has completely evolved this Imperial Armament, which possesses infinite possibilities, into another Imperial Armament entirely different from the operating armor!"
At this moment, General Black's heart was truly a jumble of mixed emotions, and he didn't know what expression to use to face reality. He had lost face, his dignity was gone, he had thrown away all his pride and brought out his family's most treasured possession, only for the opponent to also have an Imperial Armament!
Now, General Black could only pray that the performance of this demons extract, whose appearance completely differed from the records, was inferior to the admirer. If the final outcome was Budo's defeat while wielding an Imperial Armament, then the General Family's millennia-long prestige established within the Imperial Military Department would suffer an unprecedented blow!
Although it was already close to that, if they won, a significant portion could still be salvaged. After all, Rin also used an Imperial Armament, and the situation had once again become even, rather than Budo unilaterally overpowering her with an Imperial Armament.
"It doesn't matter what kind of pseudo-toy you dug out of that garbage heap; do you think I don't know what the demon possession - operating armor looks like? Foolish woman!"
Budo, clad in the admirer, gnashed his teeth as he looked at Rin, who was also using an Imperial Armament. His forehead was covered with bulging blue veins, looking as if they were about to burst.
With a delicate gauntlet covering her slender hand, Rin removed her dragon-headed helmet. Her smile remained, and she calmly said to the enraged Budo:
"You're right. The moment I put on this Imperial Armament, it could no longer be called demon possession - operating armor. It has become another completely different Imperial Armament, exclusive to me. I've named it: Demon God Dragon Armor: Knight of the Lake!"
At this point, General Black had no choice but to announce the final assessment procedure:
"Both parties' armaments have been displayed. The assessment, begins!"
