Extraterrestrial beings have invaded our garden world, hellbent on wiping humanity off the face of the planet. The only hope is a specialized force of genetically-engineered female "Pandoras" and their male partners known as "Limiters," who represent the last line of defense against a horrific alien force.
Kazuya Aoi is a Limiter who enrolls in a prestigious academy that trains genetically-engineered soldiers. Having made a promise to his Pandora sister who died in battle, Kazuya must overcome his sadness and become the best he can be. His first major obstacle is a frigid second-year student known as Satellizer el Bridget, who has remained undefeated in combat simulation. Does Kazuya have what it takes to beat her, while readying himself for an impending war?
It took a while to get into the long-term plot, but we finally get to see combat against the "evil alien invaders" who, for reasons known only to themselves, had only been showing up once every few years. Suddenly that has changed, and mankind isn't really prepared. In addition, their new fighting techniques and targets for attack suggest that they've actually been thinking about how to win, unlike the evil alien invaders in a lot of stories. That suggests bad things for humanity because, you know, evil alien invaders with both power and brains...that makes things much more difficult. The story becomes much more serious, and we finally see the human agencies that are responsible for the academies at which the Pandora and their Limiters are being trained. We also get a better handle on the ages of the characters, since the normal age for entering these academies is comparable to that of entering high school. The story still does not explain why combatants have to be that young, although there are hints that the modifications needed to become Pandora may shorten a human lifespan, but still, the oldest combatant we've seen up to this point in the series is no more than college-age. This set of stories also deals with an issue I'd been wondering about, which is the question of "what if you have the physical aptitudes for this war, but not the mind-set?" Also, some of the creepiest parents on record, even for manga, are featured in various parts of this story. I'd like to think that it's because humanity is desperate, but in the examples thus far, no, it's just creepy parents.
Briefly, I thought that this volume(s) might be better because the pandoras were finally fighting the novas. But, I was wrong. Most of the characters seem like spoiled brats. Most of the panels are fight scenes where it is difficult to see who is involved. The fighting moves sound like ice-skating (triple accel instead of triple axel. Everything is a contest -- even drinking.
