With his hands on her neck, Evan posed a question.
"Do tell, Agnes. What stops them from killing you before you can even think to activate the Mark's effect?"
Answer: Unless she subjugated all their souls, then nothing.
But there was a limit on how many souls Agnes could subjugate. It was kind of like Evan's Skill Slots. Just as the more powerful Unique Skills required more Skill Slots, so was it for Subjugating Souls in Agnes' case.
Her strength would not be enough to subjugate as many souls as needed.
Evan let go of Agnes and leaned back, before thinking about the simulation created based on a real future which EOTD had seen—Aidos Online.
'This plan of theirs also didn't work out as the Demons surely didn't have any Soul Marks…'
This whole section of their conversation revealed the inherent strategic weaknesses in Agnes' plan and the critical need for a more reliable approach to dealing with the Demon threat.
