You're enjoying a shitty day of classes at your all human school in your all human town when you randomly look outside and see a black matter ball hovering only a few hundred meters away, you turn to warn the class but it's far too late as the wave of dark mamono mana shatters the windows and knocks you down.

When you come to there are sounds of pleasured moans filling the air as well as the screams of those who are still mid-transformation. You get to your feet and witness the apocalyptic landscape as several of your transformed classmates masturbate amidst a scenery of broken glass and splintered desks decorated with still-smoldering books.

The world outside bears a night sky as the demonic energy blots out the sun and there's a chance that anyone you put your trust in could spontaneously be transformed into a clingy, horny, and extremely powerful monstergirl.

What do you do?
