Once again, Hiroto and the Build Divers gather in real life. To save the people of Eldora from the One-Eyes, they must power up their Gunpla to resist the powerful new enemies created by Alus, and discuss how to rescue Masaki Shido, whose mind is still trapped on the planet Eldora. Then Parviz makes a surprising proposal.
