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