Hajime's younger sister. She's a bubbly sixth grader who tends to fall in love with her brother's friends, a prime example being Muryou. Always optimistic, energetic and curious, Futaba is never afraid to speak her mind. She and her brother fight like cats and dogs…but in truth, she loves her brother a lot.
