Midorikawa Nao (緑川 なお Midorikawa Nao?) (April in the English Dub Glitter Force) is one of the main Cures in Smile Pretty Cure!. She is a girl with a strong sense of justice, and has no tolerance for wrongdoers. An older sister-type, she is popular even with the girls. While tough, she also has a feminine side, as she loves cute things. Her alter ego is Cure March (キュアマーチ Kyua Māchi?), or Glitter Spring in the Glitter Force dub. She controls the power of Wind.
