"Mind control?!"
"That's my guess. Mind invasion is a specialized spell that only darkness magic users can do. With that spell, they can read minds, erase memories, implant false memories, or worst, control others like a puppet," Ymir explained. "But this is a very difficult spell to do. Even His Majesty needed time to master it, as it goes against his principle when he was still bearing the holy magic."
"He told me that nobody in this world can resist mind invasion except fellow darkness magic users, and holy magic users," Ymir added. "Besides, do you not realize that His Majesty has used it on all of us before?"
Ruru tried to remember if His Majesty ever did something to her mind. But other than enhancing her telepathy, she didn't remember anything else.
