Chūta Kokonose is a middle school boy who has been able to hear a voice that no one else could hear for as long as he could remember. One day, a strange blue alien named Chips appeared and recruited him to the space police, ēlDLIVE because he fit the requirements. During his entrance test, he discovered the voice he hears actually comes from a small white alien living in his body who he later named Dolugh. Combining his power with Dolugh, he was able to complete his exam using a power called SPH (Space Pheromone), used only by aliens. Chūta, now an officer, along with his coworker and classmate, Misuzu Sonokata, and the rest of the Solar System Area station have to work together to protect the universe from dangerous criminals.
