An alliance formed around the powerful military empire.
To counter this threat, the "Sky Striker" system was developed using advanced military technology.
A single sword, forged with the wish for peace, was entrusted to a girl named "Raye" and deployed to the battlefield. "Sky Striker Ace - Raye" instantly changed tide of the battle.
However, this success was short-lived.
Suddenly appearing before Raye was "Roze," another Sky Striker created by the enemy empire.
The power of the two lone warriors on the battlefield was evenly matched, but after clashing blades many times, Raye sensed the cries of suffering deep within Roze's heart.
Each strike of the sword, imbued with Raye's feelings, further shook Roze, who had always seen herself as a mere weapon. The empire, however, did not overlook this.
The empire's operational directive of the Sky Striker Ace was changed from that of a combat weapon to a biological component of the prototype tactical weapon "Zeke." Roze's heart was once again sealed away as she reappeared on the battlefield.
"Roze is still crying out that she doesn't want to fight. I must go save her."
With strong determination, Raye engages the Sky Striker and dives into the battlefield.
