The collection of the red orbs has disturbed a nest of ancient curses that lay dormant beneath Tokyo's subsoil. Out of the darkness has emerged the Diabolical Duo Curse, a Special Grade aberration that embodies the fear of betrayal and cannibalism. It is a pale, armored giant carrying within its own mouth a second entity with red hair and a chilling gaze. The air feels heavy and smells of sulfur; this creature isn't just looking to kill you—it seeks to devour your cursed energy to mutate further. You must venture into the epicenter of the crimson mist where the entity was sighted. Be careful: the duo attacks in a coordinated fashion; While the main body uses brute force, the inner entity launches long-range ritual attacks. Your objective is to separate their cores and exorcise them before they finish consuming the residual energy still floating in the area.
"Mission accomplished. The echo of that curse's screams still lingers, but the threat has been neutralized. Thank you for facing a horror of this magnitude with such composure; the demonic nature of these new shadows is pushing many sorcerers to their breaking point, but you stand firm. You have prevented a feast that would have been fatal for the city. Your progress is our only guarantee of survival. Well done!"
