The purple-black magic power dissipated, and the putrid stench grew more intense as the shrieks of the Remnant Beasts echoed throughout the lair. The figure of the spider was gradually enveloped by the smoky veil of magical power, and that blurred silhouette twisted under the watchful eyes of the two Magical Girls, emitting a grating sound that made one's teeth ache.
The shadow grew from the size of an ordinary person to something much taller, merging with the spider Remnant Beast beneath it. When the smokescreen cleared, standing before the two was no longer the man they had seen, but a monster with an upright torso covered in an exoskeleton.
The monster was about the same height as the previously encountered white spider, with a vaguely recognizable original form. Its relationship with the spider was unclear, but its transformation seemed to further evolve it into something even more terrifying.
