Miyuki Hoshizora/Cure Happy

Miyuki Hoshizora is the leader of the Cures in Smile Pretty Cure!. She is a bright, energetic girl who loves fairytales. Although she is a scatterbrain and gets flustered easily, she has the determination to get what she wants and is seldom unhappy. Whenever she is happy, she is fond of saying "Ultra happy!". At the start of the series, she is a newly-transferred student at Nanairogaoka Middle School.

Miyuki's Pretty Cure alter ego is Cure Happy. She controls the power of the Holy light.
