The battle has begun, but Ragna and the Argentum Corps are not facing just any enemy. They are facing those who mean to exterminate them by any means necessary.

Olto Zora's cunning plan overwhelms the corps as they face the power of mature dragons. However, Crimson's impending offensive and Starlia's resolve may be the key to victory.

The tide is turning as the corps claw their way through the battlefield—Ragna and Starlia the source of their inspiration. But none are aware of Crimson's callous scheme.

Olto Zora used to be someone else once, and Starlia reminds him of someone he knew long ago.

Olto Zora and Taratectra are lifelong friends who stand at a crossroads that could determine the battle. Now, Ragna and Starlia may be the only ones who can prevent calamity.

The battle is over, but at a heavy price. While a weary corps mourn their losses, representatives from the Solarian Church arrive to meet the fabled Reaper.

Ragna has found a reason to fight, and he and the Argentum Corps will take the battle to the Blood of the Wing, no matter what Crimson thinks.

Four superior dragons stand between them and the Winged Monarch. With unyielding resolve, the Argentum Corps storm a dead capital for the final battle.

Multiple battles erupt in an all-out war against the Blood of the Wing. As each side engages in mortal combat, a crucial decision awaits Crimson.

The darkest hour is at hand. As cherished comrades fall on both sides, bittersweet memories of the past surge to the forefront.

As Ragna and Woltekamui's titanic battle rages across the heavens, the dragon is reminded of another encounter—one that shaped him into the warrior he is today.

Just as Ragna, Crimson and the Argentum Corps stand at the cusp of victory, the worst case scenario occurs: Against all odds, Ultimatia reclaims her dominion over time.
