You would reach the location where loud revving noises were reported to be coming from an abandoned warehouse. As you approach, a haunting silence surrounds the area, but the warehouse is filled with traces of both human and devil blood. You cautiously proceed, only to discover a blood-soaked teenage boy, sitting on his knees with a chainsaw for a head.

"..Mnn..." As Denji gazes in your direction, his chainsaw-like features would melt away.
