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.
