Golden Burst

Golden Burst (ゴールデンバースト Gōrudenbāsuto) is Cure Spark's first finisher, first used in episode 21 to purify the Disharmonizer. Later on, this attack is upgraded to Thunder Sonic (サンダーソニック Sandāsonikku).

Description
Cure Spark first claps her hands twice, causing two small hearts to emerge. She reaches for her heart and folds her hands together. Her hands begin to glow and spread sparks, she screams the incantation and projects the bolt at the enemy.
