The state-of-the-art ship Natsumi of the Galactic Federation Army was flown to the end of the galaxy thousands of light-years away, with 2500 crew members including apprentices on board during its habitual voyage. It is in the middle of the Quart Empire, which is in conflict with the Federation. In addition, her personality-giving ship, Natsumi, misidentifies herself as a normal human being, and she accidentally falls in love with Yutaro, a high school student who boarded her ship. The crew, who were troubled by Natsumi who only listened to Yutaro, appointed Yutaro as a temporary captain as an emergency measure. What is Yutaro's final decision on the approaching quart army !?
