Selma Payne's POV:
The more I thought about it, the more I felt it was possible.
First, Dorothy had the most unique bloodline and power among all the people present.
Ancient beings were always obsessed with so-called 'bloodlines' and 'inheritances'. Dorothy, who had the bloodline of prophecy and ancestors as chaotic as those in ancient Greek mythology, met this requirement.
Furthermore, Dorothy was the descendant of the prophetic witch. She might even be a direct descendant of Mullwica. Possessing her body would be satisfying revenge for the demons with bad intentions.
Third, Dorothy's body had bones, and the side effects of the Eye of Insight were constantly snatching away her life force. She was like a dangerous bomb that could explode at any time. If the demon wished to break free from the shackles of his body one day, then even if Dorothy died quickly, he could use the Eye of Insight as an excuse not to be discovered.
