The “Empress of Night” turns out to be none other than Wise’s mother, who she split up with after a fight in the game. When the two of them went their separate ways, the Empress decided to stop playing the game and instead go chasing after attractive men. And since she was using a powerful cheating tool that could change how the system worked, even Shirase, who is on the managing side, couldn’t stop her.
Normally, she’d face a huge fine for breaking the license agreement, but if Wise can make up with her, Shirase is willing to let it slide.
When she sees her mom flying around on a throne made of shirtless men, Wise is incredibly embarrassed. She agrees to Shirase’s plan, and the rest of the party agree to help, too.
