To counter the great powers surrounding the mighty empire, the "Sky Striker" was developed using advanced military technology. Its power was enough to instantly change the course of battle. The girl "Raye," entrusted with the "Sky Striker," repeatedly encounters the girl "Roze" from the hostile nation wielding equal power on the battlefield. Each time they clash with the "Sky Striker," Raye gradually gets a glimpse of the "human heart" within Roze and rises up to free her!

To meet Roze not as a "weapon" but as a "person"---

The girl "Roze" from the empire couldn't understand.

Why the girl "Raye," who should be her enemy, was coming to save her instead of destroying her.

Each time Roze clashed with Raye and the "Sky Striker," she felt something warm and indescribable from Raye.

The empire saw through Roze's hesitation, and she was absorbed into the tactical weapon "Zeke."

As Roze becomes part of Zeke and loses consciousness, what will she feel in Raye, who is coming straight towards her---

In the northern most reaches of a forbidden land, lies the Nation of Dogmatika.

Its people, marked by the sacred stigmata bestowed by High Priest Maximus, live beneath the unwavering rule of divine doctrine.

Receiving the High Priest’s blessing on that day was Ecclesia, the “Most Virtuous,” the only one in history to bear the stigmata on her forehead.

After the ceremony, Ecclesia stood alongside the previous Virtuous Vestal, “Fleurdelis,” speaking in earnest about what’s to come — when suddenly, the skies above Dogmatika split open.

From the rift emerged a beast thought to exist only in legend — a dragon.

Amid the flames of war, a fallen dragon boy and a wary girl cross paths. From their fated encounter begins the tale of the fallen and the virtuous.
