One girl washes up on shore - naked, scared, and alone. The other uses psychic weapons to make a blood-soaked break from captivity. One is named Nyu. The other is Lucy. The two couldn't be more different - if only they didn't have to share the same body! When star-crossed students Kohta and Yuka rescue Nyu on the beach, they're blissfully unaware that she's a diclonius, a mutant bred to replace humanity. To make matters worse: she's escaped from captivity, leaving a trail of dead in her path and the world's most lethal hunters on her tail.
As the rooms in Kohta's rented house fill with runaways and diclonius - danger mounts outside. But, what's more dangerous? The monsters beating down the door or the demons within?
