One day, her magic instructor and fiancé, Hikaru, is captured by Dogelgar, commander of Inferna. Using dark magic, Dogelgar transforms Hikaru into a lifeless doll. Determined to save him, Kurara infiltrates the enemy's hideout but encounters the demonic warrior Rengaru, who overwhelms her in battle. Rengaru demands she transform. With Hikaru held hostage, Kurara reluctantly obeys, transforming into Misty Blue.

Then, Dogelgar appears before her, holding the doll-like Hikaru. In a sudden move, Kurara lunges forward and seizes Hikaru—revealing it was part of her strategy. Now fighting while protecting the doll, Kurara gains the upper hand—until Dogelgar, enraged, unleashes a devastating magical assault, knocking the doll from her grasp. With the tide turned once more and Hikaru again held hostage, Misty Blue is forced to lower her guard. Trapped in dire peril, how will she rescue her beloved fiancé? [HAPPY END]
