Himegoto (Secret) - S2.E12

With the Nirvana back on track, all that is left now is to defend Tarak and Mejale from harvesting. But the Nirvana and the veteran pirate ship with it might not even be close to being able to fight off three or four motherships. It has come time to unite the two cultures in battle against the one, true enemy that threatens them all, but it may take Hibiki and his newfound knowledge about proving one's own existence to motivate them all to join the final battle against Earth's Harvest fleet.
