With that plan in mind, Linsley captured the Witch of Explosion and teleported her to the Avatar Syndicate's headquarters. He had already notified Hellhound to imprison her, and he wasn't worried that she could escape or cause trouble there.
If the Witch of Explosion had been able to break free from a prison guarded by countless Celestial Avatar Masters and Ascendence Avatar Masters, then those avatar masters might as well have retired.
Regardless, Linsley couldn't allow the Witch of Explosion to stay at his villa, no matter how pitiful her situation seemed. Even if it was for experimentation, it would be highly inappropriate to have another girl living in the same villa as his fiancée.
After dealing with the Witch of Explosion, Linsley took Magia Fleur's hand, and the two of them quickly fled the scene.
