Kaoru's Cure Windy form
Kaoru was one of the two persons can stay in Cure Form because Tsukasa doesn't want sacrifice even the duos. She and her sister Michiru give him the RIDE Card for new respects.
Kaoru's Cure Windy final form called Cure Windy Storm was created from Samuel's first transformation Singular Rider COMPLETE. He used her along with Cure Bright Summer to slash in one blow.
