[In the dreamscape, Welt delays for time by recreating the Eden's Star once more, continuing that same battle from the moon.
In reality, at the base of Babylon Tower, Siegfried and his wife, who had been unconscious for a long time, finally awaken.
Theresa had long been waiting with their weapons in hand. At the top of Babylon Tower, Sirin remains in a state of silence. Honkai energy had left her body, yet it stopped spreading beyond ten meters around her. Looking at the data analysis from the Alahato, Einstein sighs—the Moonlight Throne had failed... However, the Moonlight Throne weakened her connection to the Herrscher Core. This meant the core could now be forcibly extracted from her. "Hold on, Alahato... and Joachim."
In the illusion, Welt collapses before Sirin yet again, his fate unknown.
After mocking him, Sirin summons a Void Lance to finish him off—but the moment it materializes, it dissipates into nothingness. Sirin clearly feels her power fading away. In reality, Alahato has already extracted one core. Sirin impales Welt with a Void Lance before abruptly awakening, causing the extracted core to obediently return to her body.
As Alahato is destroyed and Sirin prepares to kill Einstein—to make humanity suffer the same pain as Bella—
Three warriors wielding Divine Keys arrive on the battlefield. Sirin dodges the chains of Judah but is ensnared by vines summoned from the White Flower. "Cecilia... so you've come too? As I thought—your goal was always to destroy me!"
"Damn it! Damn it! Get away from me!!"
Faced with Cecilia's betrayal, Sirin finally feels despair.]
[March 7th]: "We really weren't wrong—Mr. Yang died again."
[Stelle]: "Why does this not even surprise us anymore?"
Fu Hua: "Probably because we've gotten used to it after seeing it so many times."
[Honkai Star Rail - Welt]: "Fu Hua, you really have the nerve to say that about me?"
[Yunli]: "This last scene kinda feels like 'Three Heroes Battle Sirin.'"
[Mobius]: "As my little assistant said, you truly know nothing about Honkai. A true Herrscher has absolute control over their core."
[Vill-V]: "Using the Moonlight Throne against the Second Herrscher? Of course it failed. We've researched anti-Honkai weaponry for so long—did you really think it'd be that easy?"
[Mei]: "The Moonlight Throne was close to the right answer, though your current version still lacks sufficient output."
[Silver Wolf]: "Honestly, I'm more curious how they'll turn this around. A rampaging final boss versus three half-dead heroes?"
[Vill-V]: "Let's hope Sirin lives up to her title as the Six-Core Herrscher when she gets serious."
[After her outburst, Sirin traps Siegfried and Cecilia in a separate dimension, leaving only Theresa to face her in reality. "I won't let you have your way!
Show her our power—Judah!"
"The Oath of Judah—Zeroeth额定 Power, activate!"
Records from the Previous Era describe the Herrscher of Binding as an exceptionally unique Herrscher whose ability was to create a barrier with a radius of 100 kilometers. Within this barrier, all forms of Honkai energy would be nullified, while all other energy would be weakened to varying degrees. Inside it, MANTISes would suffer bodily dysfunction and die within a minute, while ordinary soldiers would lose bioelectricity and perish swiftly. Though her destructive power paled compared to other Herrschers, within this barrier, she was invincible. It was theorized that she was an "anti-Herrscher" created specifically to counter MANTISes and Divine Keys. It was only after this that Dr. Mei proposed the hypothesis of a "Will of Honkai."
Taking a deep breath, Theresa fully deploys
Judah: "I'm counting on you, Judah!"
Countless golden gears unfold from Judah, shooting forth chains that bind Sirin. Under the authority of Binding, Sirin's power vanishes—even her Herrscher attire fades away, reverting to her original lab gown.]
[Tesla]: "Isn't this just cheating? Does Honkai specifically target humanity's weaknesses?"
[March 7th]: "What's next—a Herrscher that specifically counters human technology?"
[Stelle]: "Maybe don't jinx it right now."
[Honkai Star Rail - Welt]: "...March 7th, please don't tempt fate."
[Yanqing]: "Did they not consider the user when designing this weapon?"
[Vill-V]: "Little boy, when Judah was completed, we never intended for anyone using Divine Benediction Barrier to return alive."
Raiden Mei: "Against such a powerful Herrscher... I'm even more curious how the Previous Era defeated her. How would we deal with her if we encountered her?"...
[Kalpas]: "Herrscher... you're dead!"
[Mobius]: "Little mouse~ don't ask questions you shouldn't."
[Su]: "It was a tragedy... an unspeakable tragedy."
[Once Divine Benediction Barrier fully activates, not only does Sirin lose her power—even Theresa suffers excruciating pain as if her body were splitting apart.
Forcing herself to stand, Theresa hurls her spear, but due to her weakened state, it only strikes Sirin's leg. Deprived of her Herrscher authority, Sirin recalls her days as a lab subject. Only then does she realize—though her Honkai energy is gone, her Herrscher Core remains. Staggering forward with her spear as support, Theresa reaches Sirin and drives it through her chest! Then—time runs out. Theresa reaches her limit as Divine Benediction Barrier collapses. All that remains is an exhausted Theresa... and Sirin's "corpse."]
[Stelle]: "Is this not just Judah's launch platform? Let's be real—didn't Judah do all the work in this fight?"
Kiana: "Hahaha! Auntie Theresa—so you're just S-Rank Valkyrie Judah and her mount-launcher, huh?"
[Theresa]: "Kiana... I think your training intensity is still too light. Let's increase it."
Kiana: "Nooo! Auntie! Mei, save me!"
Raiden Mei: "Kiana... you're on your own."
[Sushang]: "So... is the Second Eruption over just like that? Did Theresa get MVP?"
[Qingque]: "Nay, nay~ According to Xianzhou operas, this is exactly when a desperate counterattack happens!"
[Mobius]: "Divine Benediction Barrier dispersed too quickly. For Death's authority, a mere fatal wound is child's play."
