A video blogger attempts to fake cryptid sightings to boost his views, but gets more than he bargained for when his crew is slaughtered by a real monster. Elsewhere, students find themselves preyed upon by a sandworm-like beast, initiating a desperate struggle for survival on their own school grounds.

With nothing but the keyword Kagewani to lead him, he scours the sites of recent attacks in hopes of finding a lead to eradicating the creatures for good. However, Sousuke finds that these threats to humanity are even closer to home when the pharmaceutical company, Sarugaku, starts to encroach on his investigation.
