Piena, the largest nation on the continent, is having its annual ritual dance festival. The semi-finalists and winner are allowed to compete against the previous champion, Princess Nachetanya. One of the competitors is a daring boy, Adlet Meyer.

Adlet and the princess head for the Land where Demons Howl, past Gwenbyer, the Kingdom of Iron Hills. Ten days after they leave Piena, they meet villagers escaping from the fiends. Adlet suspects a trap, but challenges the fiends anyway!

The Braves head for the barrier temple, but they encounter a massive army of fiends along the way. To seal the fiends in, they'll have to fight their way past. And to make matters worse, scores of flying fiends are bombing the temple!

The Six Braves have gathered, but the phantasmal barrier has been activated. With only one means of deactivating the barrier, the Braves must figure out which of them is the fake Brave. Meanwhile, Flamie reveals a surprising secret.

With the others suspicious of him, Adlet must convince them that he is not a traitor. But to do that, he must discover how the temple was breached and the barrier activated. With the others have consolidated their suspicion of him, what will he do?

Adlet flees into the jungle to escape the other 6 braves. He talks with Flamie about her past. Is she the false brave?

Adlet fights Hans, who finally realizes that he's not the false brave. Chamot, however, is not so easily convinced.

Chamot summons a horde of monsters to kill Adlet and Hans. Adlet comes up with an answer to the mystery, which Flamie shoots down.

Maura tricks Nachetanya into going insane and trying to murder Adlet. Adlet declares his undying love for Flamie.

Nachetanya decides that Adlet has betrayed her, and launches a full-on attack. Only Flamie can protect him from the combined might of the rest of the Braves.

Having revealed "how" the seventh managed to trick the Braves, the only question left for Adlet to answer is, "Who is the seventh?"
