From her relentless exchange with the Pureblood, Serah had pieced together several crucial discoveries.
The first and perhaps most telling was that the demon had yet to reveal its complete form. All the attacks it had unleashed so far, though savage and overwhelming, were merely fragments of its true power—half-measures disguised as devastation. That realization alone meant she had not yet seen the full depths of what the Pureblood was capable of, and that in itself was both alarming and exciting.
The second discovery was far more problematic: the demon possessed the ability to shift its core throughout its body. This made it nearly unkillable, for even a fatal strike could amount to nothing if the core was no longer in that location. It was an insidious advantage, the kind of survival mechanism that turned every exchange into a gamble, forcing her to fight with more precision and patience than ever.
