High school girl Ogura Sio is on a trip to Taiwan with her class when mysterious creatures attack humankind. To save her only friend, she'll need a weapon--the kind of weapon only one of the great souls of old can give her.

Now that Sio's been identified as an e-gene holder, she faces a hard choice: can she bear to leave her old life behind to join the fight for Earth's freedom?

DOGOO sends Sio off to get some battle training, and she's strictly forbidden from contacting her family and friends until she finishes. But she just might get the chance to make some new friends on base...

Sio's sent into battle in a Category 4 hurricane before she's finished her training. Will some dancing lessons from an ancient warlord make up the difference? Will she be able to hit a moving target this time?

Sio is assigned to the 2nd platoon. When she joins up with them on their airship, she learns that e-gene holders just keep getting weirder. Meanwhile, DOGOO learns something new about the Evolutionary Invaders--and it's not good news.

The 1st platoon is transporting an Evolutionary Invader when their plane crashes in Alaska during a blizzard. Finding shelter at a nearby science lab seems simple enough, but...

A ghost ship appears near Panama with Evolutionary Invader eggs on board--the battleship Musashi, sunk in October 1944. Can DOGOO safely neutralize it in time to avoid nuclear war? And can Sio snap out of her warship mania long enough to focus?

Vidocq discovers something important about how the Evolutionary Invaders are communicating. It's time for the 1st platoon to move out--and when the mission gets a little crazy, the 2nd platoon is called in to back them up.

Sio and Kaoru are reunited at last when Sio visits Japan for medical treatment, but their happy reunion is interrupted by an Evolutionary Invader attack.

We take a trip back in time to discover how DOGOO began and what lies in the Commander's past. Meanwhile in the present, Jack and Sio prepare for a new mission.

Sio makes her debut as operation commander as the fight to kill the underground Invaders begins.

As the battle heats up, everyone's AU weapons are pushed to new levels to compensate for the Invaders' new evolution.

Will Operation Stone Forest manage to neutralize the threat of the pre-evolved cells? And just what is "Mode Nightingale"?
