Belial looked at the Demon Princesses in front of him, and he slowly raised his axe, but then the axe fell from his grasp. He had no strength left to fight them, and he was frustrated that those Demon Princesses were relentlessly fighting him and didn't show any sign of exhaustion. He lost because the Demon Princesses were invincible, and he couldn't kill them no matter how many times he cut their bodies.
"It was a mistake to let them live," Belial said and then fell into the sea that used to be an ice field.
Vixelleth brought Belial's body back to the surface with her water magic and then tossed him to where Mykel and the others were. Zagan, Vinea, and Bael were shocked when Belial lost to fake demons, and they were frustrated and infuriated because of it.
