Chapter Summaries

Einstein and the others searched the evacuated children for the immature Second Herrscher, Sirin, but realized she had stayed behind to absorb energy from Babylon Laboratory’s reactor. They rushed back to the laboratory and found that Sirin had already absorbed a massive amount of Honkai Energy.

• Einstein learned that a child who might be the person they sought had been evacuated, so she and Welt hurried to catch up with the children.
• Han Jiang told Kiana that the dangerous culprit behind the laboratory’s Ghost Incident was among the children.
• Einstein tested the children in the transport vehicles but found no sign of the Second Herrscher.
• Theresa realized Sirin was missing, and Einstein concluded that Sirin had stayed at the laboratory to absorb Honkai Energy from its reactor.
• The group raced back to Babylon Laboratory, where Welt sensed that the reactor’s output had fallen by more than eighty percent.

The group discovered that Judas's Oath could track Sirin by sensing her Honkai Energy, and Theresa activated its tracking mode. When hundreds of Honkai Beasts attacked Babylon Laboratory, Welt split the group so he and the others could pursue Sirin while the rest defended the laboratory.

• Welt and Einstein determined that Sirin had escaped Babylon Laboratory by tearing through space, leaving them with no easy way to locate her across the ice field.
• Einstein extracted Sirin's remaining Honkai Energy and used it to activate Judas's tracking function, which Theresa awakened by sensing the weapon's soul.
• Judas transformed into tracking mode and pointed Theresa toward Sirin, with a range of two hundred kilometers.
• Siegfried received word that approximately three hundred Honkai Beasts had appeared near Babylon Laboratory, though the children had already evacuated safely.
• Welt ordered Einstein, Salome, and Nicholas to defend the laboratory while he, Siegfried, and the others followed Theresa to track down Sirin.

Siegfried, Welt, Kiana, Han Jiang, and Theresa tracked the Second Herrscher through the snow and found a giant egg that swallowed Theresa. As Kiana and Siegfried searched for a way to free her, nearby rocks began to loosen, leaving the group facing another danger.

• Siegfried called Cecilia to apologize for missing dinner, and Kiana excitedly greeted her over the video call.
• Theresa used Judah to lead Welt, Siegfried, Han Jiang, and Kiana through the snow while the others stayed to guard the Babylon Laboratory.

Han Jiang, Kiana, and Welt fought Sirin in Fu Hua’s simulation, where Welt’s replicated arsenal overwhelmed her until Otto intervened to protect her. Han Jiang escaped Otto and went to help Kiana, who had found Sirin.

• Han Jiang and Kiana emerged from Sirin’s spatial gates as Welt summoned an expanding army of mechs and aircraft through Understanding Replication.
• Fu Hua interrupted the simulation because she could not fully reproduce the Herrschers’ powers, then restored it with Kiana receiving only a subconscious impression of the missing scenes.

Sirin threatened Earth with meteorites and demanded that Welt come to the moon, while also insisting that Han Jiang accompany him. Welt prepared to go, and Anti-Entropy and Otto began discussing a plan to collect lunar Soulium samples that might reveal how to seal Honkai Energy.

• Sirin sent meteorites crashing into Earth and warned that she would send more every seventy-two hours unless Welt came to the moon.
• Tesla revealed that Anti-Entropy’s Silver Bullets had failed near the moon, and Welt concluded that Sirin had gained new powers.
• Einstein presented an analysis of meteorite fragments and explained that lunar Soulium might contain the code for sealing Honkai Energy, so Welt decided to travel to the moon and asked Siegfried to contact Otto.

• A Schicksal researcher reported that thirty-two girls qualified as test subjects for the organization's experiments.

Sirin remembered how Schicksal’s Babylon Laboratory had imprisoned and killed Agata, Aurora, and Bella, then summoned three girls from crystals and sent them to destroy human cities. The chapter ended with Bella still fighting Kiana while Nicholas and Salome struggled against the surrounding Honkai Beasts.

• After the children arrived at Babylon Tower, Schicksal locked Sirin, Agata, Aurora, and Bella in its underground laboratory and subjected them to experiments.
• Sirin and the others tried to escape, but the staff caught them, and Agata died after an experiment with an increased dose of Honkai Energy.

As the Second Herrscher threat approached, Siegfried chose to inject it, while Otto rallied Schicksal and announced its preparations for war.

• Siegfried’s power erupted during the data viewing, freezing the laboratory before he eventually collapsed and regained consciousness.
• Dr. Einstein explained that Siegfried’s Honkai Beast power caused nerve damage and could be controlled with a Hyper-Evolution Factor activator, but warned it could irreversibly transform him.
• Dr. Einstein explained that the activator’s effects varied by person and noted Han Jiang’s unusual resistance to Honkai Energy.
• Siegfried injected the activator, deciding that he would risk becoming a Honkai Beast to protect his wife and daughter.
• Schicksal urgently summoned its Valkyries, and Otto delivered a global speech declaring that the organization would fight the Second Herrscher’s forces.
