Inside Chiba Academy, a young girl knelt on the ground, feeling her own power. She now possessed unimaginable ability and strength. The girl had murdered everyone who had once bullied her, and naturally, she had killed everyone else in the entire academy as well.
At a Schicksal branch, Theresa asked, "Isn't it supposed to be only one Herrscher per Honkai eruption? How is there another Herrscher-level energy signature?" The person on the communications line replied that it was an accident—perhaps surplus Honkai Energy generated by the Third Honkai eruption had been collected. "Alright, I'm heading out immediately," Theresa said.
Inside the academy, Theresa spoke to the dazed Herrscher: "It must be painful. I'll grant you release now." With that, Theresa thrust the spirit spears of Judah toward the Herrscher. The next instant, Theresa was struck by vines. Realizing something was wrong, she immediately leaped out a window and fled, leaving behind Oath of Judah. The vines were coated in a virulent poison, against which even Theresa, with her rapid regenerative abilities, was helpless.
Theresa quickly ran out of Chiba Academy, but the poison coursing through her body continued to worsen, and she eventually collapsed unconscious. At that moment, Yae Sakura appeared. She rescued Theresa and voluntarily transformed into a Stigmata to protect her.
The next morning, the Pseudo-Herrscher looked at Judah lying on the academy path, a sudden surge of hatred welling up in her heart. The Pseudo-Herrscher tried to attack Judah with her vines, but they were directly bounced away.
Just then, Theresa appeared and said, "Judah is made of Soul Steel; it's impossible for an attack like that to leave even the slightest scratch." The Pseudo-Herrscher laughed, "You're a defeated foe coming back to throw your life away!" "I was just careless yesterday. I'm actually very strong." With that, the Pseudo-Herrscher attacked again with her vines. Theresa picked up Judah to block, and then launched a counterattack using Judah's spirit spear form. After a round of combat, the Pseudo-Herrscher sustained quite a few injuries, whereas Theresa remained uninjured.
Yet at this moment, the Pseudo-Herrscher laughed, "Haven't you realized yet? Even though my vines didn't hit you, having absorbed a massive amount of Honkai Energy, I can use the vines to generate toxic gas in the air. Given enough time, you'll end up just like yesterday." Having inhaled a large amount of toxic gas, Theresa immediately collapsed to the ground. Just as the Pseudo-Herrscher manipulated her vines to kill Theresa, Theresa stood up once again. However, her behavior was no longer human; she dodged the Pseudo-Herrscher's attacks like an animal, and instantly used Judah to activate its spirit blade form, slicing the Pseudo-Herrscher into pieces in mere seconds.
That night at St. Freya, Yinyu and Kaslana sneaked out of the dormitories once again, and Yinyu put Kaslana through physical training. Just then, Himeko ran past carrying Theresa toward the infirmary. Thinking they had been caught, Yinyu and Kaslana obediently followed along, hoping to earn Teacher Himeko's forgiveness—only to realize that Himeko hadn't noticed the two of them at all, and they had only been discovered because they tagged along.
The doctor stated that the patient was in no major danger, though she was currently delirious. Suddenly, Theresa woke up: "Five hundred years... This body is mine now!" For some reason, Kaslana and Yinyu grabbed onto Theresa tightly to keep her from running around. Unfortunately, Kaslana's strength was too small and she was directly thrown aside, leaving only Yinyu holding on. Himeko had already returned to the girls' dormitory, and Zhang Lin thought to himself, *What are we supposed to do now?*
Suddenly, Theresa stopped struggling and collapsed again. Zhang Lin had no choice but to pick Theresa up, preparing to carry her back to the girls' dormitory. As they parted, Yinyu secretly snapped a photo to commemorate the scene, then returned to the boys' dormitory by herself.
Upon reaching the girls' dormitory, Mei took Theresa from them and invited Kaslana inside to help brainstorm a solution. Zhang Lin said, "It must be the influence of the Stigmata. We just need to enter the Stigmata world."
