Fujimiya awakens a monster, Zonnel, with the intention of stopping an asteroid headed towards the Earth. While Fujimiya might want to preserve the planet, Gamu fears that he's not as concerned about saving human lives.

Hiroya's frustrations with humanity reach an apex as he enacts a plan to end what he sees as their futile hopes by destroying the Aerial Base. Gamu is the only one who can stop him.

After struggling through his first battle as Gaia, Gamu is somewhat forcibly drafted into XIG. It soon becomes obvious that not all threats to the Earth will be arriving from outer space.

A jellyfish-like monster with incredibly destructive powers seems to be immune to conventional attacks, and Gamu turns to his school friends to develop a weapon that XIG can then use to take the creature out.

When Gamu is baffled at how the monstrous Gan Q seems to defy the laws of physics, his faulty instructions cause the XIG offensive to go disastrously, and he sets out to find redemption along with an effective attack method.

A mysterious typhoon seems to be caused by something other than the weather, and it's up to XIG to prevent the unnatural disaster from wreaking too much havoc.
