Everyone faces uncertainty at some point in life — even a genius like Tenma. But he never imagined that choosing to save a life rather than advance his career would lead to the creation of a true monster. Years later, in post-reunification Germany, childless couples are being murdered one after another. The killer’s identity is known, but his motives remain a mystery. Tenma embarks on a perilous journey to find the killer’s twin sister, who might hold the key to unraveling the terrifying enigma of the “Monster.”
