Demons were experts at playing with souls, so things like possessing a body were easy.
But in fact, few demons would do this. The reason was naturally very simple—the compatibility between the soul and the body.
Since Roy had experienced the soul replacement event of the illusion demon César, he was well aware of what kind of adverse consequences there would be if a demon rashly placed their soul into a body that was not so compatible. Moreover, generally speaking, if the body did not obtain the corresponding power, even if the demon changed bodies, they would fall into a pit instead.
Kha-Beleth's body was now destroyed, but he had signed a contract with the Dragon of Chaos, Urgash, so his soul did not return to the Abyss. The Ouroborus Mark was naturally unable to reconstruct his body, so if he did not want to survive in such a dangerous soul state, he would have to find another body.
