The vampire Scarlet lost her brother Crimson when Niscura invaded Paradia. Her grief has become something larger and more dangerous: a conviction that the entire human race is to blame. She has hired Team Supernova to build three space stations capable of absorbing stellar energy and generating a supermassive black hole to consume everything. Sicari cannot travel to space, which means it falls to the robot K-16 to go up there and prevent it.
