At the restricted area of St. Freya High School.
Anti-Entropy's Einstein and Cocolia had successfully infiltrated the restricted area.
Although this area was protected by defenses that not even a Herrscher could break through, and encryption that would take Schicksal's most advanced computer cluster seven hours to crack...
Unfortunately, the designer of these defenses felt the decryption time was too long, and so, with a bit of mischief, left a backdoor.
And the designer of Schicksal's defense system was none other than Einstein, who had served Schicksal sixty years ago and had now defected.
"This is as far as you go!"
Theresa, standing outside the main gate with a Faux Judah larger than herself on her back, shouted to stop Einstein and Cocolia inside.
"Well, well, well, isn't it Theresa? It's been a while, and you haven't grown an inch~" Cocolia turned around and mocked her.
"Hmph. You vixen from Anti-Entropy, I've seen through your tricks. Surrender quietly!"
"Tsk, you didn't go to save the Third Herrscher? I'm surprised Otto was willing to risk losing the Third Herrscher to have you come here first. It seems what's in here is indeed more important than the Third Herrscher!"
"Heh, what risk... Do those monsters even need me to save them..."
Theresa thought about Kika's firepower, the sentient Judah, the complete Herrscher Ryn, and Kiana in her White Knight: Moonlight battlesuit... it seemed that, by comparison, she was the weakest one.
"It's been a long time, Ms. Theresa." Einstein, having finished cracking the defense system, also turned to greet Theresa.
"Einstein?! You're part of this operation too!!!"
Theresa immediately flew into a rage. She hated deceit and betrayal, especially being betrayed by a comrade who had fought and died alongside her.
"We fought together in the campaign against Sirin. I thought there might be some good people in Anti-Entropy. But I never expected you to be here, that you would dare to conspire with others to harm my students!!!"
Clang—
Theresa placed the Faux Judah on the ground. It expanded, revealing its sharp chain-spears.
"The tragic state of the Valkyries from the Canghai City branch is constantly on my mind... I believed in Welt, Tesla, and you, and I've been suppressing my anger. My reason told me it's normal for a large organization like Anti-Entropy to have some bad apples, but to think you, Einstein, are one of them!!!"
"Faux Oath of Judah, standby!"
"Looks like you and Theresa have some friction, Einstein!" Cocolia said teasingly, watching Theresa charge over with her chain-spear.
"Titan mecha A2304, observation system offset. Quantum state disengaged!"
At Cocolia's command, dozens of Titan mechas appeared out of thin air, blocking Theresa's path and halting her advance.
"Heh, I once thought you guys teleported your mechs directly via quantum positioning like Schicksal... I didn't expect you to convert them into a quantum state and carry them with you. Condensing from a quantum state to a physical entity, Anti-Entropy actually achieved such a theoretical technology."
"But are you underestimating me too much! Daring to use something like a Titan mecha, a toy for kids, against me!
Let the Principal teach you the proper etiquette when facing an S-rank Valkyrie!"
"Heh, your weapon, the Oath of Judah, can greatly weaken Honkai Beasts and Honkai Zombies by suppressing the Honkai energy within their bodies. But what use is that against my beloved tactical mechas?"
"Pfft, heheh."
Cocolia's confident look made the furious Theresa laugh.
"It seems you know nothing about powerful Valkyries, and you clearly don't understand my Judah at all. Although this is just a Faux Judah, apart from not being able to activate its Zeroth Power, it's not much different."
Theresa patted the Faux Judah, and it contracted back to its original form, leaving only a few chains wrapped around the cross for Theresa to grip.
"Let me show you the hundred ways to use Judah!"
Theresa grabbed the chains, lifted the Faux Judah, and leaped into the air. She then hurled it forward, smashing a Titan mecha several meters tall into scrap metal.
"Final deployment. Faux Oath of Judah!"
At Theresa's command, the Faux Judah fully expanded again, and its thirteen long spears shot out as beams of light.
Theresa walked towards Cocolia step by step. With each step, the thirteen light spears descended from the sky, piercing through the Titan mechas one by one, annihilating them all.
A beam of light reformed into a chain-spear in Theresa's hand, and she aimed it at Cocolia's throat.
"Game over, you vixen from Anti-Entropy!"
Theresa's combat prowess had scared Cocolia into a cold sweat, but even with death a second away, she maintained a look of holding a winning hand.
"Hehe, it's just that our quantum technology isn't mature yet, so we could only bring this many. When my real Titan mecha army arrives, how will you handle that, Theresa?"
"Stop, don't do it, hear me out!"
Cocolia quickly motioned for Theresa to retract the spear. If she had shouted a moment later, Theresa's spear would have pierced her neck.
Wiping the blood from her neck, Cocolia had Theresa look at Einstein. "Since I dared to break in here, I naturally have an ace up my sleeve to ensure a safe retreat."
Einstein stepped aside, revealing the path to the restricted lab's interior, gesturing for Theresa to enter.
"Ms. Theresa, please take a look inside the opened laboratory! I believe once you see it, you will understand that we are not enemies."
Theresa entered the lab and saw several conspicuous large characters—「Sirin Project」
"Sirin Project? The Second Herrscher's name... Heh, I've long known that Schicksal has been researching the Second Herrscher Sirin's abilities. If that's what you came for, then there's even less reason for me to let you leave."
"Is that so? Then why not take a closer look!" Einstein activated a switch in the lab, revealing row upon row of countless experiment pods.
When Theresa saw the individuals submerged in the endless rows of pods, she froze completely. The chain-spear in her hand slipped from her grasp and clattered to the floor.
Inside the experiment pods... were clones of Cecilia and Kiana, one after another...
Einstein leaned in close to the petrified Theresa's ear and said to her.
"Theresa, this is our objective. We went through all this trouble to break in here just to show you this, to let you know the truth about the Sirin Project and the K-series..."
"All communication here has been blocked by us. Otto and the others will not know what has happened here. Now, let's make a deal! It's all for the sake of the ones we love..."
Not far from where the three were talking, Cortana was watching everything through a camera.
"I'm screwed, I'm screwed, I'm screwed! Is it too late for me to delete the data and run? This news is too explosive, how am I supposed to tell Ryn and Kiana..."
Cortana, while cursing herself for being so curious as to follow them, silently downloaded all the data from the laboratory regarding the Sirin Project and the K-series.
