Guts and Caska are both tied to the interstice because of their brands, thus allowing Guts to sense apostles and other magical creatures with his brand and also one of the reasons for his increased abilities. Flora and Schierke are both magic users (with Farnese learning) and thus they are knowledgable about magic, the other layers of reality, and so forth, not to mention being able to use magic. The apostles, while not human anymore, were once human, and now are both of the real world and the other lower layers of reality.
I was wondering though, what exactly does it take for someone, on in the case of the Dragon Slayer, to be able to interact with the interstice. For example, by using and gaining a better control of their magical weapons and in Serpico's case, cloak, could him and Isidro become influenced by the interstice or something of the sort?
