Aesop, a genius alchemist determined to restore the fallen House of Pershilad, finally creates the ultimate bio-weapon — the “Final Calamity,” intended to be the cornerstone of world domination. According to plan, a terrifying monster should have been born... But instead, what emerged from the incubation tank was a beautiful girl. Convinced that she must possess some hidden power, Aesop conducts a series of tests — but all the results fall within the normal range for an average human. To make matters worse, she’s afraid to sleep alone and keeps sneaking into Aesop’s bed at night. At his wit’s end, Aesop throws the Final Calamity into the zone where his most dangerous “companions” are imprisoned. But the Final Calamity, unwilling to be separated from Aesop, finally awakens her true power…?!
