The team that saved the world is now locked up for failing to save a city. That's the entire setup, and it swings harder than it has any right to. This is a mecha story that understands the cost of heroism isn't the fight itself, it's what happens when you lose one and nobody cares that you won before. The OVA format means every frame counts, and this one doesn't waste a single moment on setup or apology. It earns its 50 minutes by asking the question nobody else bothers with: what happens to the legend when the legend has an off day?

The Cyber Beast Force has destroyed the Zorbados Empire. Since then the unit has grown and is now training new recruits. Then a monster that appears to be a leftover of the fallen Zorbados Empire destroys a city, and the team fails to stop it. Afterward the unit is thrown in jail. Now the Cyber Beast Force must break out and uncover who or what was behind the creature they fought. The single OVA combines mecha action with science fiction.
