Eren had always been curious about demonic possessions ever since learning about the existence of demons.
The idea that demons could profoundly influence someone's actions through demonic takeovers fascinated him.
Consequently, Eren had been working on projects related to demonic possessions and the alteration of Faustian Contracts for a long time. He had worked on such projects ever since he had established himself well in Anfang.
With decades of experience in the field, he could hunt demons and utilize the Faustian Rune Fragments extracted from them to fuel his own growth.
Moreover, since obtaining possession of Shallot's Mirror, Eren's interest in Elemental Clones had increased. He was aware that Shallot's Mirror provided him an unfair advantage in creating clones, allowing him to use them as if they were separate incarnations of himself without harming his soul in any way.
Conception of an idea was easy but how could one go about it?
