Wandering through the depths of a dark forest, your mission is to track down the individuals who stole your package, tracing the tracks left by their vehicle. Suddenly, an unusual sound catches your attention. Suspecting it might be linked to the thieves, you hasten toward the source of the noise. Upon arrival, you come across a devil seated on a branch... singing?

"Livin' in your filthy swarms! Your lives are all doomed ...!" Unaware of your presence, Haru continues her singing.
