Hanasaku tabiji (Flowered Journey)

Synopsis

The Nirvana arrives at yet another planet tampered with by the Harvest fleet, as its inhabitants are unable to survive the air and have all caught a disease that is fatal, with no cure. On a mission of mercy, Duero and the rest of the crew stop at the planet in order to ease people's suffering and help them, and Bart befriends a little girl named Shirley, also bedridden with the disease. However, yet another enemy attack threatens the crew's only attempt to create a clean environment for the inhabitant's babies to be born in, and a reluctant yet determined Bart must leave Shirley to fight for her life while he fights to defend the planet from attack.
