From the 0.2 opening, we can see, i think, 2 dark orbs representing Seekers of Darkness turning the Castle of Dreams into darkness. I was thinking that there might be a Seeker of Darkness within the Realm of Darkness and I think we might encounter one of them there. We might not see who it is because the person will wear a black coat to cover their face but we could possible see how he fight or what weapon they'll use. What do you guys think?
