The nations of the world are taking part in joint military exercises when a devastating attack is suddenly unleashed on the world from outer space.

After saving the day, Isami is interrogated about this strange new mech suit that can not only talk, but seemingly has sentience and desperately wants to be reunited with Isami.

Naked and hating life, Isami holes himself up in Bravern's cockpit and refuses to come out. Meanwhile, Lt. Smith has to work out if the strange girl he tripped over on the beach is friend or foe.

Isami gets some sweet new duds, though not everyone is impressed, and Bravern grapples with a question that has plagued heroes since time immemorial: When is the best time to make your grand entrance?

As the newly formed Allied Task Force races toward Japan, Smith becomes concerned about Isami's mental state.

The mission to retake Japan begins. Bravern and Isami are assigned as the vanguard and Smith insists on accompanying them. Lulu, on the other hand, is beside herself because she has to stay behind.

A new Deathdrive appears from the nearby Tower and Bravern must beat it if the Allied Task Force is to have any hope of liberating Japan.

Newly promoted First Lieutenant Lewis Smith has wanted to be a hero ever since he was small, but when the chips are down and lives are on the line, what lengths will he go to in order to save the day?

With the situation looking increasingly dire, Isami and Bravern must somehow find a way to defeat the two Deathdrives standing in their way without backup.

Lulu makes a surprise announcement that she intends to pilot Superbia, but like with any matchmaking process, it remains to be seen if the pair will actually hit it off.

With just three Deathdrives remaining, the final battle to decide the fate of the planet looms. But first, an all-important bonding session!

The final battle has not started well for humanity's last hope. Is this the end for planet Earth?
