Once, three wizards opened a door to another world, and the human world was filled with mysterious magic.

Many years passed, and the magical power brought forth advanced civilization, magical wisdom enriched people's lives, and the power of wizards made nations and organizations even more formidable.

The three wizards became legendary figures known as the great "Three Sages (Magistus)"...
Then, one day, signs of the resurrection of the evil demon they had sealed away began to appear.
And, sensing these signs, wizards from all over the world began to take action in secret.

One is the sorcerer king who rules a formidable magic city.
Another is the head of the magic craftsmanship guild.
And the third is a young man who has heard rumors of an ancient summoner.

They are heading towards a familiar land,
to meet their former friend, now a demon, once again.

A closed-off land.

In this land, isolated from the outside world since ancient times, a gateway to the abyss, known as the "Hole," occasionally appears.

The "Hole" sometimes swallowed land and people into another dimension like a calamity, and at other times brought blessings like the grace of God.

Those who live in that land protect and compete for limited resources, and eventually unite under the umbrella of "species."

With numerous nations and organizations vying for power, a history of bloody warfare was etched onto the land.

And now, in the far north, a conflict continues between two species.

The chosen people, bestowed with the stigmata by their leader "Maximus," wield the power of miracles.

---The miraculous nation beloved by the gods, "Dogmatika, the Dogmatika Nation"

The demi-humans, who do not bear the stigmata, rose up to resist the invasion of the Knights of the Training Order.

--- The armed beastmen group "Tri-Brigade"

On that day, a festival was being held in Dogmatika to celebrate the current saint, "Ecclesia."

While the people rejoice and pray over the existence of the "purest saint," the Iron Beast Front launches an infiltration operation into the Dogmatika territory to rescue the prisoners.

As if it had been waiting for this chaos, the abyss slowly opened its jaws, the "hole."

Great powers centered around powerful military empires.

To counter this threat, the weapon "Sento" was developed using advanced military technology.

A single sword, imbued with a wish for peace, was entrusted to a young girl named Ray, and when "Sky Striker Ace - Ray" was deployed onto the battlefield, it instantly changed the course of the battle.

However, that dominance did not last long.

Suddenly appearing before Ray was another Sky Striker Ace created by the military empire, "Roze."

The two men, the only two on the battlefield, were evenly matched in strength, but as they clashed blades in numerous battles, Ray sensed the deep-seated anguish hidden within Rose's heart.

Ray's sword strikes, imbued with his feelings, further swayed Rose's heart, which had previously defined herself as a weapon, but the Empire did not overlook this.

The operational strategy for Sky Striker Ace was changed from using them as combat weapons to using them as biological components for the prototype flash-art weapon "Sieg." Rose's mind was sealed once again, and she reappeared on the battlefield.

Rose is still crying out that she doesn't want to fight. In that case, I will definitely save her.

With unwavering determination, Ray activated Sky Striker and descended upon the battlefield.
