As the war for Alcia stretches from the depths of the Abyss to the Wall of Paradise, Licht and Tokikaze meet on the field of battle. The two brothers have been trapped by their love and hate for three hundred years, and their unleashed bloodlust rocks the very heavens. A word from Hina could be all that is needed to decide the match, but will she meet the same tragic end as her mother...?

Tokikaze is alive, and he’s more interested in revenge than reunions. Abducting Hina and stealing the Original Ballots, he and the Abyss launch an all-out war on Alcia! Just what is he planning, and how does Hina fit into the equation? As the three-hundred-year-long peace comes to an end, a wounded Licht must ally with old enemies if he is to have any hope of defeating his old friend!

To reverse Schmerman’s overwhelming numerical advantage, Jail heads to the royal capital alone, armed with nothing but his beliefs. Even though thousands of soldiers stand in his way, his sights remain fixed on two goals—taking the seat of commander in chief of the royal army, and eliminating Robert, the traitor who currently sits in it. As battle lines are drawn and war approaches once more, a duel unfolds between the two with their lives, their pride, and the future of Alcia hanging in the balance!

Captured by Douan and the Special Unit, Hina, Lynn, and Pele are brought face-to-face with Major Schmerman. What happened to the kind teacher of three hundred years ago? What did Douan experience during the war? And is Licht really dead? The gang searches for answers as the battle for Alcia heats up!

Finally, the Waste War begins! As outside forces start to obliterate the school, the members of Class A-including Tokikaze and Jail-dive headfirst into an enemy-infested area to protect their friends. Meanwhile, an unconscious Rihito undergoes a risky operation far removed from the chaos outside. Will the blissfully unaware Ace-to-be make it in time to save his comrades?!

In the world of Alcia' where rank is determined by "counts" a young girl named Hina scours the land for the fabled Ace-the legendary hero of the Waste War. With only the last words of her missing mother to guide her search' she wanders from town to town until she meets Licht' a clownish masked vagrant with a count of --999. Girl-crazy and unpredictable' he's the exact opposite of a hero...or at least' that's how he appears...

Class is in session! As newly enrolled students of Special Military School #13, the gang must plunder stars in order to become soldiers-a title the perpetually hormonal Rihito couldn't care less about. While juggling studies and military training, Jail and the others begin to look for the meaning behind their mysterious time slip, only to come across the school's disturbing connection to the Aces...
