Misumi Ryouta (renamed Ryan Blackstone in the English dub) is a character in Futari wa Pretty Cure. A part of the Misumi family, he is Nagisa's younger brother. He often seems to annoy his sister Nagisa and as a result becomes a target for a wrestling hold called the "Cobra Twist". He also seems to have a crush on Honoka despite him being in elementary school. In Futari wa Pretty Cure Max Heart it is revealed that he plays badminton in almost the same way that his sister plays lacrosse. He worries about his sister since he sometimes hears her talking to Mepple and thinks she may be talking to herself or she's just being plain weird.
