When Miyabi finally stops running away, her mascot partner, Saint, gave Miyabi her Lovely Brooch and PrePhone but soon after that a Yasha appeared and attacksthem. Sachiko transforms into Cure Happiness and tells Miyabi to either transform or hide behind a bush. She watches Miyabi hide behind the bush and attacks the Yasha with her kicks and punchs and her attack Royal Empathy.
