Ch. 501I Refuse to Be a Valkyrie! Chapter 501
Nocturne explained that the black box contained Hiyamaru, the Twelfth Herrscher, whose power awakened after she was killed in the previous era. Fifty thousand years of imprisonment and the fear and hatred of modern human test subjects weakened the box’s seal, while Yae Sakura’s resentment had only been the final trigger.
- Nocturne took the sealed black box and identified its prisoner as the Twelfth Herrscher, who had destroyed humanity’s last stronghold in the previous era.
- Flame Moth captured Hiyamaru, an ordinary girl whose intense Honkai reactions made them suspect she was a Herrscher, and lower-ranking personnel killed her out of fear.
- After Hiyamaru died, her Herrscher of Corruption powers awakened, and she corrupted the base and launched strategic weapons around the world.
- Dr. MEI sealed Hiyamaru in a box and tried to turn her core into a Divine Key, but the resisting consciousness left it incomplete.
- The Heavenly Mandate Organization later used the box in human experiments, whose subjects’ fear and hatred weakened its seal.
- Nocturne explained that Yae Sakura’s emptiness and resentment had only been the final straw in the seal’s collapse.
