Transformation Sequence

Cure Sonata

Sayaka holds up her Heart Mirror with her ring glowing a bright blue. She then swipes the ring across the mirror shouting "Pretty Cure, Medley Start!". Music staffs wrap around her legs and body before turning into ice and shattering revealing her heels and outfit. She crosses her arms across her chest with musical staffs surrounding them turning to ice with her gloves appearing after the ice shatters. Her hair then fades from sapphire blue to icy blue before then getting put into place with blue bow, she then tilts her head to the side as blue earrings appear.  She then strikes a pose before flying down from the sky and introducing herself.


Sonata Freezing - Cure Sonata summons her Melody Mic before twirling it around forming ice crystals around her before shouting the attack name and firing the crystals at the target.

Sonata Blizzard - Cure Sonata summons her Melody Mic before twirling it around and tracing a diamond with the Mic before shouting the attack name and sending a fury of ice and snow at the enemy.


Hikami (氷上) - Hi (氷) means ice and Kami (上) means top, Together they mean on top of ice. A reference to her powers over ice.

Sayaka (さやか) means bright.

Her name means "bright ice on top".
