Trained as an elite pilot, Hachimaki Hoshino's life collecting space debris in orbit around Earth doesn't satisfy the engine of his ambition. So when the Earth Development Community begins to look for a crew to man Welnar Rocksmith's new Mars mission, which involves traveling to the red planet on the brand new space ship Brown Fawn in search of a specific breed of plant life, he naturally would want on.

His father, Goro Hoshino, is a legendary astronaut and has already been selected as the mission commander. But getting selected will mean proving the wealth of his knowledge in space, demonstrating his capacity for team work, and embracing love and friendship as guiding principles for his life.
