Fighting to protect the city, Aurora discovers the creature's weakness and corners it—just one step away from victory. But the perverted monsters born from evil desire are not limited to just one! Now Aurora faces a new threat: the mechanical horror, Mecha-Zetsulinger. Can she defeat the hellish lust demon spawned from wicked desire—the insatiable Zetsuringer—and save the city from ruin?!
