Soya is an ordinary boy, with one problem: He's lost his memories and lives with a giant cat and a maid. To make matters worse, his city is under attack by a giant alien craft, and it doesn't come in peace. It comes in... "Peas"?

The first of the seven heroes is down, and Soya is eager to taste his victory katsudon. Could it be delicious pork, or perhaps chicken? At last, meat! But then he finds out... it's vegetarian katsudon!

Soya won his battle with Miu, but the rest of Grand Paladin shows up to stop him. In the ensuing battle, he's defeated, and sensei is forced to take drastic measures to keep him from being captured.

Haru's armor goes out of control, becoming a massive dragon. To stop it, Grand Paladin and the pacifist faction will have to join forces.

Grand Paladin's numbers are fading fast, and the Sealing Faction won't stop coming. With nobody left to help Takashi but his own father and the timid Yosuke, will there be anyone to save the Earth?

Kogane was a Nebula spy. Grand Paladin is destroyed, and Takashi, alone, has to fight off the Sealing Faction. Will Soya help him, even if they're enemies?

The battle is over, and Grand Paladin and the Sealing Faction have both been driven off. But what comes next?

The vials are now in posession of the pacifists, but the battle isn't over. They were simply the key to unlock Grand Paladin's psychic powers. Now, afraid for what humanity may become, some of Grand Paladin are joining with the sealing faction.

Benika is accidentally sealed, and now she dreams that everything she ever wanted is hers. But the sealing faction is far from finished...

After all the skirmishes up to this point, it's now time for the sealing faction and pacifists to settle things with one, decisive battle.

The dragon has awoken on the moon, and is threatening to destroy Earth like it did Sirius. Nebula has a plan to seal him, but can the people of Earth put their hatred towards him aside after everything that happened?
