From SBM's translation of chapter 1:
"13 years ago, an unknown object appeared at Shinjuku. That creature regularly gives birth to a demon. Therefore, our world is being eaten clean."
The military found a weapon capable of fighting these creatures, a special power known as "exex" that becomes part of the human body.
From the author of Ubel Blatt.
