Cure Jaune holds up her Rainbow Pen and summons the power of the Yellow Rainbow, causing a stream of yellow hearts to swirl around her. She then kisses the palm of her hand, forming a yellow heart. She throws it and it circles around her, multiplying into several hearts, then back into one large heart that hits the target, which purifies it.
