Haruka Deep-Ando

 was a human military conscript in the 38th century assigned to a rescue team sent to investigate why all contact had been lost with Le Verrier space station in orbit around Neptune. Considering himself the joker of the group, Deep-Ando soon discovered that this mission was no laughing matter when he became separated from his unit and face-to-face with the Sandmen, a conglomeration of sentient sleep dust that had evolved from the Morpheus process and consumed their sleeping hosts. He evaded the Sandmen for a time, but was cornered by the creatures and killed. (TV: Sleep No More)
